Error 1044 sql

I have strange error. I am logged in local Mysql as root via command line. After creating database: create database some_db; Then giving privileges to some user: grant all privileges on some_db....

I have strange error. I am logged in local Mysql as root via command line. After creating database:

create database some_db;

Then giving privileges to some user:

grant all privileges on some_db.* to some_user@'localhost' identified by 'password';

This is giving error:

ERROR 1044 (42000): Access denied for user 'root'@'localhost' to database 'some_db'

The permissions for the root(show grants;) shows:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '*8919C53DC7A4DFBF3F8584382E96463583EB7FDA' 

I am also making sure i am logged in as root:

select current_user();

And this confirms that i am logged in as ‘root’@’localhost’

I have created database and assigned user multiple times and never had an issue. Why i am unable assign user to the database created by root while logged in as root?

p.s. from other posts, i am thinking the issue may be caused due to some strange users

select host, user from mysql.user;

Some users that i have not added but does show up:

 MY_COMPuTER_name.local |       ''
 MY_COMPuTER_name.local |     root

I tried to delete these users

drop user 'root'@'MY_COMPuTER_name.local';
drop user ''@'MY_COMPuTER_name.local';

However, while it states query run successful, the users are not dropped even after flush privileges. Why i am unable delete users? Any help is much appricated

I developed my website, but many pages that access the database throw the error ‘SQLSTATE 42000 1044 access denied for user’. Can you help!

That was a recent support ticket received at our Outsourced Technical Support department where we resolve support queries for web hosts.

Website owners often face this error due to insufficient database privileges, typo errors in username/password, and more.

So, what’s the solution here? Well, the solution varies depending on the reason for this error.

Today, let’s discuss the top 5 reasons for this error and how our Dedicated Support Engineers fix it.

‘SQLSTATE 42000 1044 access denied for user’ – What this means?

Before we move on to the reasons for this error, let’s first get an idea of this error.

Website owners usually face this error when MySQL disallow access to a database.

For instance, the complete error message looks like this:

SQLSTATE[42000] [1044] Access denied for user 'test'@'localhost' to database 'test_database'

This error shows that MySQL denies the user ‘test’@’localhost’ access to the ‘test_database’ database.

[You don’t have to be a MySQL expert to keep your websites online. Our MySQL admins are available round the clock.]

‘SQLSTATE 42000 1044 access denied for user’ – Causes and Fixes

In our experience managing servers, let’s see the main causes of this error and how our Dedicated Support Engineers fix it.

1) Incorrect details in website configuration file

This is the most common reason for the error ‘SQLSTATE 42000 1044 access denied for user‘.

Database driven websites like WordPress, Drupal, etc. use the details in the website configuration file to connect to the database and fetch data.

So, typo errors in the database name, database username, password, hostname, database port, etc. can lead to errors.

How we fix?

In such cases, our Hosting Engineers recover the database details, and correct them in the website configuration files.

And, if we can’t recover the password, we reset it and update it in the website configuration file.

Also, we ensure that the new password adheres to the MySQL password policy.

For example, in cPanel servers, we reset the database user password from

cPanel > Databases > MySQL databases > MySQL users > Current users.

sqlstate 42000 1044 access denied for user

MySQL databases option in cPanel

2) Database user doesn’t exist

Similarly, this error occurs when the user trying to access the database doesn’t exist on the MySQL server.

Also, this error can sometimes occur when the database user isn’t properly mapped to the database.

How we fix?

In such cases, our Support Engineers check whether the database user exists in the MySQL user table.

If not, we check the user’s requirement and if valid, we create a user with that username.

In addition to that, we assign this user to the corresponding database.

For instance, in cPanel servers, we map the database user to the database from cPanel > Databases > MySQL Databases > MySQL users > Add User to Database.

3) Insufficient database user permissions

Sometimes, database users don’t have the right privileges to access the database.

In such cases, website owners see this error ‘SQLSTATE 42000 1044 access denied for user

How we fix?

Here, our Hosting Engineers grant the user, proper privileges over the database to correct this problem.

For example, in cPanel servers, we assign access privileges to a user from here:

cPanel > MySQL databases > Current databases >Privileged users > Click on the database user

sqlstate 42000 1044 access denied for user

How to set database user privileges in cPanel

On plain servers, we assign the user privileges from command line.

For example, we use the below command to grant all privileges to the user, ‘test’@’localhost to the database ‘test_database’.

GRANT ALL PRIVILEGES ON test_database.* TO 'test'@'localhost';

And, in-order for the changes to reflect, and the privileges to be saved, we use the below command.

FLUSH PRIVILEGES;

[Struggling with database user permissions and privileges. Our MySQL experts are here for your help.]

4) Existence of anonymous users

Website owners face this error when there exist anonymous users like ‘ ‘@localhost or ‘ ‘ @127.0.0.1.

That is, when a client connects to the database, MySQL looks through the rows in the user table in a sorted way.

And, it uses the first row that matches the hostname and username.

So, here the anonymous user precedes all other users when connecting from localhost.

How we fix?

Our Support Engineers check the MySQL user table and remove the anonymous user.

For instance, we use the below command to remove the anonymous user from MySQL user table.

delete from user where User=' ';

5) Missing PDO module

Website developers see this error when trying to access the database using PDO.

PDOException: SQLSTATE[42000] [1044] Access denied for user 'test'@'localhost' to database 'test_database' in lock_may_be_available() (line 164 of /home/test/public_html/includes/lock.inc).

And, this often occurs due to the missing PDO module.

Most web hosts enable PDO module by default, but some web hosts may disable this module.

How we fix?

In such cases, our Hosting Engineers enable the PDO module on the server.

On cPanel servers, we enable it exclusively for the domain via the PHP Selector option.

sqlstate 42000 1044 access denied for user

PHP Selector in cPanel

[If you suspect missing PHP modules in your server. Our Support Experts can fix it for you within minutes.]

Conclusion

In short, ‘SQLSTATE 42000 1044 access denied for user’ error can occur due to insufficient user rights, typo in username/password, and more. Today, we’ve discussed the top 5 reasons for this error and how our Dedicated Support Engineers fix it.

Troubleshooting the MySQL 1044 “Access Denied” Error

When you import a database using phpMyAdmin, generally you are importing a text file with a .sql extension.

Here is a section of code that may be in a .sql database backup. In this example, the database we are trying to import is named Employees.

-- phpMyAdmin SQL Dump -- version 2.11.9.5 -- https://www.phpmyadmin.net -- -- Host: localhost -- Generation Time: Apr 02, 2010 at 08:01 AM -- Server version: 5.0.81 -- PHP Version: 5.2.6   
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";   
CREATE DATABASE employees;   
-- --------------------------------------------------------   -- -- Table structure for table `employee_list` --   
CREATE TABLE 
IF NOT EXISTS `employee_list` ( `first_name` text NOT NULL, `last_name` text NOT NULL ) 
ENGINE=MyISAM 
DEFAULT CHARSET=latin1; 

When using phpMyAdmin to attempt to import such a file, you will receive an error message similar to:

 Error
 
SQL query:
  
 CREATE DATABASE employees;
  
 MySQL said: Documentation
 #1044 - Access denied for user 'training'@'localhost' to database 'employees'   

In this scenario, my cPanel username is Training. Because of cPanel’s database naming conventions, all database names must begin with the cPanel username followed by an “_”. I cannot create a database named Employees, however I can create a database named Training_employees.

The reason this import failed is because of the following line in the .sql file:

CREATE DATABASE employees

Again, I cannot create a database named employees, however I can create a database named Training_employees. If I change the line that says: CREATE DATABASE so that it creates: training_employees instead of employees it will again fail with the following message:  

 Error
  
 SQL query:
  
 CREATE DATABASE training_employees;
  
 MySQL said: Documentation
 #1044 - Access denied for user 'training'@'localhost' to database 'training_employees' 

When using cPanel, databases must be created within the cPanel itself. To fix the issue, you will need to:

  1. Create the: training_employees database within cPanel
  2. Comment out the: CREATE DATABASE command in my .sql file. To do this, simply change: CREATE DATABASE employees; to — CREATE DATABASE employees; You are simply adding dash dash space to the front of the line to comment it out so that it will not be executed.
  3. Log into phpMyAdmin, access the training_employees database, and then import as normal.

В данной статье пойдет речь об ошибке 1044 Access denied when using LOCK TABLES, которую вы можете получить при попытке создать резервную копию с помощью утилиты mysqldump.

Описание

Полностью текст ошибки выглядит следующим образом:

mysqldump: Got error: 1044: Access denied for user ‘user’@’localhost’ to database ‘database_name’ when using LOCK TABLES

Как видно из текста ошибки, проблема заключается в том, что пользователь, под которым вы пытаетесь сделать резервную копию, не обладает правами на «LOCK TABLES». Вот что говорит мануал, по этому поводу:

Исправляем ошибку

Как видно из описания, решить данную проблему можно как минимум двумя разными способами.

Способ (быстрый)

Достаточно добавить к mysqldump аргумент —single-transaction , т.е. целиком команда для создания резервной копии будет выглядеть примерно так:

Способ (чуть дольше)

Необходимо просто выдать тому пользователю (в нашем примере «user»), под которым мы пытаемся создать резервную копию права на «LOCK TABLES» на ту базу(-ы), резервную копию которой(-ых), мы пытаемся создать. Для этого, необходимо подключиться под учетной записью root к MySQL серверу и выдать нужные права. Делается это следующим образом:
1) Подключаемся к MySQL серверу под учетной записью root

2) Выдаем нужные права для пользователя, под которым мы пытаемся сделать резервную копию

MySQLdump: Got error: 1044 when selecting the database

by Nicky Mathew | May 13, 2021

Stuck with the error, MySQLdump: Got error: 1044? We can help you.

Recently, we had a customer who came across this error while trying to make a backup using the mysqldump command.

As part of our Server Management Services, we assist our customers with several MySQL queries.

Today, let us see how to solve this error.

MySQLdump: Got error: 1044

While trying to make a backup using the mysqldump command, we may come across:

We will get this error if we try to dump the database with a user which has not enough privileges to access the selected database.

Here, the user is missing the LOCK privilege.

mysqldump requires at least the;

  • SELECT privilege for dumped tables,
  • SHOW VIEW for dumped views,
  • TRIGGER for dumped triggers, and
  • LOCK TABLES if the single-transaction option is not used.

We ensure to lock all tables to be dumped before dumping them.

In addition, we lock the tables with READ LOCAL to permit concurrent inserts in the case of MyISAM tables.

Since the –lock-tables lock tables for each database separately, this does not guarantee the tables in the dump file are logically consistent between databases. Tables in different databases may dump in completely different states.

Solution

Moving ahead, let us see an effective method our Support Techs employ to fix this error for our customers.

1. Initially, we assign proper privileges to the user to access the database.

To do so, log in to MySQL and run:

Here, we provide the MySQL root password. Then we grant all privileges on the database to our user:

Similarly, to grant all the privileges:

Next, to flush the privileges and exit from the MySQL we run:

2. Then we run the same mysqldump command, add the –single-transaction flag.

[Need help with the error? We are available 24*7]

In short, how our Support Techs resolve the mysqldump error.

Troubleshooting the MySQL 1044 “Access Denied” Error

When you import a database using phpMyAdmin, generally you are importing a text file with a .sql extension.

Here is a section of code that may be in a .sql database backup. In this example, the database we are trying to import is named Employees.

When using phpMyAdmin to attempt to import such a file, you will receive an error message similar to:

MariaDB error 1044 – Fix it now

Trouble with MariaDB error 1044? Here’s help.

The 1044 error code indicates that the user has insufficient permissions to make changes to the database.

As part of our Website and Server Management Services, we receive support requests from Webmasters, Web hosts and Digital Agencies to fix database errors such as this.

Today, we’ll take a look at the top reasons we’ve seen for MariaDB error 1044 and how our Support Engineers fix it.

Different causes for MariaDB error 1044?

Every application like PHPMyAdmin, WordPress or even a command terminal client connects to a MariaDB database with a username.

That username should have the privilege to manage the database.

It is usually provided by the website administrator or the managed hosting provider.

But there are cases where the permissions are incomplete or the authentication details aren’t right which can lead to MariaDB error 1044.

Let’s dig into the details.

1. Entering an incorrect Username

Some administration tools generate random usernames that are hard to remember.

We have seen many users copy-paste database usernames, which sometimes omits a letter or adds a space at the end.

MariaDB interprets this as the wrong username, and denies access:

2. Wrong Password due to typo

This is one of the most common reasons for database errors.

It is often that customers enter the wrong password due to typo. Or they can leave the password empty while executing the command.

Since the password doesn’t display due to encryption users may not see the error right away.

3. Missing to set the user privileges

Every database user has a particular database. To link them, user privileges must be set to the database.

Sometimes, customers create a database and also create a username for it.

However, if they are unaware of the user privileges that need to be set for the database then they don’t set it. Also, in some cases, they forget to set user privileges. Because they will not be prompted with the option or any message to set the user privileges after the database and username creation.u

This will also lead to errors.

How we fix MariaDB error 1044

Now, we have discussed the reasons that cause the MariaDB error. Let’s now discuss how our Support Engineers fix this error.

Recently, we received a request from one of our customer. He was not able to connect to the database through the command prompt.

Let’s briefly check how our Support Engineers went troubleshooting the error and fixed it.

1. Initially, we checked for the available username.

The above command provided the list of the usernames in the server. And it confirmed that the customer was using the right username.

2. Further, we checked for the user privileges. So, for checking it we used the below command:

3. Thus, we found here that the username was not linked to the database. So, we set the user privileges for customer’s username ‘username’ by using the command:

Finally, this fixed the error.

Conclusion

In short, MariaDB error 1044 is either caused due to incorrect username or empty password or user privileges. Today, we discussed how this error occurs and its fix.

This page will assist you with troubleshooting a MySQL — 1044 «Access Denied» Error Message.  A MySQL denial error sometimes occurs when a database is imported through phpmyadmin.

Note: If you are using cPanel, databases must be created using either the phpMyAdmin or the MySQL Database option.

1044 Access Denied Error Resolution

When you import a database using phpMyAdmin, normally you do so by importing a text file with a .sql extension. Here is a section of code that may be in a .sql database backup. In this example, the database we are trying to import is named employees.

— phpMyAdmin SQL Dump
— version 2.11.9.5
— http://www.phpmyadmin.net

— Host: localhost
— Generation Time: Apr 02, 2010 at 08:01 AM
— Server version: 5.0.81
— PHP Version: 5.2.6

SET SQL_MODE=»NO_AUTO_VALUE_ON_ZERO»;

CREATE DATABASE employees;
— ———————————————————

— Table structure for table `employee_list`

CREATE TABLE IF NOT EXISTS `employee_list` (
`first_name` text NOT NULL,
`last_name` text NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

When using phpMyAdmin to attempt to import such a file, you will receive an error message similar to:

Error

SQL query:

CREATE DATABASE employees;

MySQL said: Documentation
#1044 — Access denied for user ‘training’@’localhost’ to database ’employees’

In this scenario, the cPanel username is «training.» Because of cPanel’s database naming conventions, all database names must begin with the cPanel username followed by an _.  Using this format you can only creat a database named training_employees.

The reason this import failed is because of the following line in the .sql file (show above)

CREATE DATABASE employees;

Again, you cannot create a database named employees, however I can create a database named training_employees.

If I change the line that says: CREATE DATABASE so that it creates: training_employees instead of employees it will again fail with the following message:

Error

SQL query:

CREATE DATABASE training_employees;

MySQL said: Documentation
#1044 — Access denied for user ‘training’@’localhost’ to database ‘training_employees’

When using cPanel, databases must be created within the cPanel itself.

Here are the steps to correct this issue:

1. Create the training_employees database within cPanel
2. Comment out the CREATE DATABASE command in my .sql file

To do this, simply change:

CREATE DATABASE employees;
to
— CREATE DATABASE employees;

You are simply adding dash dash space to the front of the line to comment it out so that it will not be executed.

3. Log into phpMyAdmin, access the training_employees database, and then import as normal.

В данной статье пойдет речь об ошибке 1044 Access denied when using LOCK TABLES, которую вы можете получить при попытке создать резервную копию с помощью утилиты mysqldump.

Описание

Полностью текст ошибки выглядит следующим образом:

mysqldump: Got error: 1044: Access denied for user ‘user’@’localhost’ to database ‘database_name’ when using LOCK TABLES

Как видно из текста ошибки, проблема заключается в том, что пользователь, под которым вы пытаетесь сделать резервную копию, не обладает правами на «LOCK TABLES». Вот что говорит мануал, по этому поводу:

mysqldump requires at least the SELECT privilege for dumped tables, SHOW VIEW for dumped views, TRIGGER for dumped triggers, and LOCK TABLES if the —single-transaction option is not used. Certain options might require other privileges as noted in the option descriptions.
For each dumped database, lock all tables to be dumped before dumping them. The tables are locked with READ LOCAL to permit concurrent inserts in the case of MyISAM tables. For transactional tables such as InnoDB, —single-transaction is a much better option than —lock-tables because it does not need to lock the tables at all.
Because —lock-tables locks tables for each database separately, this option does not guarantee that the tables in the dump file are logically consistent between databases. Tables in different databases may be dumped in completely different states.

Исправляем ошибку

Как видно из описания, решить данную проблему можно как минимум двумя разными способами.

Способ (быстрый)

Достаточно добавить к mysqldump аргумент --single-transaction, т.е. целиком команда для создания резервной копии будет выглядеть примерно так:

mysqldump -u user -p --single-transaction database_name > database_backup.sql

Способ (чуть дольше)

Необходимо просто выдать тому пользователю (в нашем примере «user»), под которым мы пытаемся создать резервную копию права на «LOCK TABLES» на ту базу(-ы), резервную копию которой(-ых), мы пытаемся создать. Для этого, необходимо подключиться под учетной записью root к MySQL серверу и выдать нужные права. Делается это следующим образом:
1) Подключаемся к MySQL серверу под учетной записью root

mysql -u root -p

2) Выдаем нужные права для пользователя, под которым мы пытаемся сделать резервную копию

GRANT LOCK TABLES ON database_name.* TO 'user'@'localhost';

database_name — название базы данных, резервную копию которой вы пытаетесь сделать, необходимо поменять на то, которое подходит для вашего случая.
user — имя пользователя под которым вы пытаетесь сделать резервную копию, необходимо поменять на то, которое подходит для вашего случая.
3) Отключаемся

The management of MySQL databases has come a long way thanks to tools like phpMyAdmin. Using phpMyAdmin you are able to not only manage your existing database but also import data from a database backup file with just a few clicks. Sometimes, however, you may run into an issue where a backup fails to import successfully and phpMyAdmin presents you with error 1044 “Access denied for user”. In this article, we will go over why this issue occurs and how to resolve it.

What Causes the phpMyAdmin Error 1044 “Access Denied for User”?

At its core, phpMyAdmin error 1044 signals that there may be something wrong with the permissions assigned to your database user. As the “Access denied for user” description suggests, your database user lacks the necessary privileges to execute one or more of the commands contained within your database backup.

The 1044 access denied error is generally limited to shared hosting accounts since they often do not have full root access to the database server. As such, you may run into this issue if you are using our free website hosting, premium shared hosting, or our Semi-Dedicated web server plans. The only hosting package where you would not be faced with such an issue is our VPS Cloud Hosting plan.

Which Commands Are Restricted in Shared Hosting?

In most shared hosting environments you will not be able to issue commands that directly manipulate entire databases. For example, you will not be able to create or delete a database using SQL commands. The two screenshots below illustrate what happens when you try to create and drop (delete) a database while working in a shared hosting environment:

Dropping (deleting) a database is a feature that will not be available on most shared hosting accounts and would yield a 1044 access denied error.

Depending on the type of SQL commands that are contained in your backup file and the server configuration, the importing process may partially succeed. In other words, you can see an “Import has been successfully finished” message while also being presented with an “Access denied for user” error. If this happens to you, it is best to further troubleshoot the issue as you would almost certainly be missing some amount of data. You can view an example of such an error below:

Do not be deceived by the success message phpMyAdmin may report. If you see the access denied error, then some data was probably not imported successfully.

In addition to database creation and deletion, in most cases, there are other types of commands that may be restricted if you are using a shared hosting plan. For instance, you may not be able to create new database users and grant them privileges. To learn more about these restrictions, you can read our article on what do to when a database user has insufficient privileges.

How Can the “Access Denied for User” Error be Fixed?

The first step in fixing the phpMyAdmin error 1044 ”Access denied for user” is identifying the problematic SQL commands. Once identified, these commands need to either be removed or they need to be run in a manner that would not cause such issues.

The two most common SQL commands that can lead to a 1044 access denied error have to do with the creation and deletion of an entire database. Such commands are often included when you make a backup of your MySQL database.

Your MySQL backup file can be packaged in different ways. In some cases, it can be provided to you as an archive using the .ZIP, .RAR, TAR, .7z or a similar extension. If you do have an archive on your hands, you would need to extract it and obtain its contents. The contents themselves should contain one or more files that have the .TXT or .SQL extension or perhaps no extension at all. You should be able to open these files using a plain text editor. If you are using Windows, we recommend opening the files using Notepad or Notepad++, Mac users can use TextEdit, and Linux users can use nano or vim.

In this article, we will use the sample code below:

/******************************************
Create the musicshop database
*****************************************/

DROP DATABASE IF EXISTS musicshop;
CREATE DATABASE musicshop;
USE musicshop;

-- create the tables
CREATE TABLE categories (
categoryID INT(11) NOT NULL AUTO_INCREMENT,
categoryName VARCHAR(255) NOT NULL,
PRIMARY KEY (categoryID)
);

CREATE TABLE products (
productID INT(11) NOT NULL AUTO_INCREMENT,
categoryID INT(11) NOT NULL,
productCode VARCHAR(10) NOT NULL UNIQUE,
productName VARCHAR(255) NOT NULL,
listPrice DECIMAL(10,2) NOT NULL,
PRIMARY KEY (productID)
);

CREATE TABLE orders (
orderID INT(11) NOT NULL AUTO_INCREMENT,
customerID INT NOT NULL,
orderDate DATETIME NOT NULL,
PRIMARY KEY (orderID)
);

-- insert data into the database
INSERT INTO categories VALUES
(1, 'Guitars'),(2, 'Basses'),(3, 'Drums');

If we try to run this code in phpMyAdmin, we would get the 1044 error. This is because we are attempting to both create and delete a database via SQL commands on a shared server. The specific code that is causing these issues is the following:

DROP DATABASE IF EXISTS musicshop;
CREATE DATABASE musicshop;
USE musicshop;

Since we cannot run these commands via phpMyAdmin, we would need to perform them by hand using the Database Manager section of the Hosting Control Panel:

  • the first command DROP DATABASE IF EXISTS musicshop; instructs us to delete a database called musicshop if it already exists.
  • the second command CREATE DATABASE musicshop; instructs us to create a new database called musicshop.
  • lastly, the third command USE musicshop; simply asks us to make sure that musicshop is the active database. We can do that by opening it in phpMyAdmin.

Once the problematic commands are performed manually, we need to remove them from the backup file. Using the text editor of your choice, remove the commands outlined earlier in our tutorial and then save your changes. In our example, the end result would be a file with the following contents:

/******************************************
Create the musicshop database
*****************************************/

-- create the tables
CREATE TABLE categories (
categoryID INT(11) NOT NULL AUTO_INCREMENT,
categoryName VARCHAR(255) NOT NULL,
PRIMARY KEY (categoryID)
);

CREATE TABLE products (
productID INT(11) NOT NULL AUTO_INCREMENT,
categoryID INT(11) NOT NULL,
productCode VARCHAR(10) NOT NULL UNIQUE,
productName VARCHAR(255) NOT NULL,
listPrice DECIMAL(10,2) NOT NULL,
PRIMARY KEY (productID)
);

CREATE TABLE orders (
orderID INT(11) NOT NULL AUTO_INCREMENT,
customerID INT NOT NULL,
orderDate DATETIME NOT NULL,
PRIMARY KEY (orderID)
);

-- insert data into the database
INSERT INTO categories VALUES
(1, 'Guitars'),(2, 'Basses'),(3, 'Drums');

This file should now be fully compatible with shared hosting environments and you should be able to import it without any issues using phpMyAdmin:

Success! The modified backup file was successfully imported via phpMyAdmin with no error 1044 in sight.

Success! The modified backup file was successfully imported via phpMyAdmin with no error 1044 in sight.

The 1044 Access Denied Error Persists. What Else Can Be Done?

In rare cases, you may still be faced with the ”Access denied for user” error once you perform the above actions. If this happens to you, we recommend thoroughly checking your entire SQL code for any other CREATE DATABASE or DROP DATABASE statements.

Depending on how the database backup was made, it may be instructing phpMyAdmin to create not one, but multiple databases in one go. In these situations, you would need to use the CREATE DATABASE commands as dividers and split your backup file into several files where each file is responsible for restoring a single database.

Then, you would need to follow our guide as outlined above for each of these backup files in order to manually carry out the database creation and deletion commands.

Conclusion

While the phpMyAdmin error 1044 “Access denied for user” may sound serious and difficult to resolve, in most cases, it actually takes a just handful of small edits to fix the problem. All you need is a few minutes of work, patience, and a plain text editor. And if all else fails, you can always contact the 24/7 Technical Support Team via a Trouble Ticket for additional assistance.

For Web Hosting packages

In the IONOS web hosting packages, the use of the MySQL commands CREATE DATABASE %DatabaseName% and USE %DatabaseName% are blocked for you for administrative reasons. Imports of SQL files that contain these commands fail with error 1044 — Access denied. To import a database nevertheless, for example to change the MySQL version, follow the steps below.

  • Make a backup copy of the SQL file you want to import.
  • Open the SQL file with a text editor, such as Notepad++.
  • Search for strings that are CREATE DATABASE %Database name% or USE %Database name%. %DatabaseName% is a placeholder for the actual database name in your SQL file.
  • Delete these commands. Be careful not to inadvertently remove other statements.
  • Save your changes.

How to import the cleaned SQL file into a database is described in the article Restoring a MySQL Database with phpMyAdmin.

Example

The following extract from an SQL file contains the CREATE DATABASE command in line 11 and the USE command in line 12. Since there are no other commands in either line, you can delete these lines completely.

-- phpMyAdmin SQL Dump
-- version 2.6.4-pl3
-- http://www.phpmyadmin.net
--
-- Host: db123456789.hosting-data.io
-- Creation Date: 01. Januar 2013 um 12:00
-- Server Version: 5.3.3-7+squeeze14
--
-- Database `db123456789`
--
CREATE DATABASE `db123456789` DEFAULT CHARACTER SET latin1 COLLATE lating1_english2_ci;
USE db123456789;

Fixing Error #1046 — No Database Selected

If you encounter the message Error #1046 — No database selected in phpMyAdmin instead of Error #1044, simply click on the database name on the left side in phpMyAdmin. Your database is now selected, and the database name will then also be displayed in the upper-right corner by the server name. Now you can repeat the import process.
