How to Solve Error ERROR: syntax error at or near “[” on the Restore Process of a Database in PostgreSQL Database

Introduction

Actually, this article has a relation with the existence of the previous article. That previous article exist in this link with the title of ‘How to Solve Error Message Model Attribute Problem SyntaxError: invalid syntax in Django Application’. It is actually just inappropriate format of the column name available in the SQL file. That SQL file actually containing an INSERT statement for restoring data to the targeted database. But since there is a column name which is not following the standard rule which starts with a character that is not number or letter, it cause the restore process to fail.

The following is just to describe that accessing the database is not the cause of the problem.

After that, the process for inserting records by importing it or restoring it using the following command exist as follows :

As in the above command execution, it fail with an error message appear.

Solution

Actually, the solution for the above error message causing it is because of the column’s character is not a proper name for a column name. In that case, just change it into a proper one. So, edit the SQL file and find the column’s character or the column name which is the cause for the database restore process to fail. Changing the column name from [product_code] to another proper one. That new column name is ‘product_code’. After editing the file, just execute the process for importing or restoring the data once more as follows :

Fortunately, the process is a success as in the output of the command above.

Ошибка Error syntax error at or near 1 в PostgreSQL: что это такое?

Многие пользователи сталкиваются с ошибка Error syntax error at or near 1 в PostgreSQL. Уведомления о сбое в программе обычно достаточно корректны. Скорее всего причина в том, что драйвер редактирует детали. Обычно достаточно посмотреть на журнал Postgres, где присутствуют все сведения.

PostgreSQL – что это?

Реляционная система информации, помогающая пользователям упорядочить сведения и иметь общую картину об их взаимосвязи. Информационная база имеет открытый код, и ее поддержка осуществляется на протяжение 30 летнего периода с момента разработки. Она наиболее востребованная у пользователей, из аналогичных реляционных баз данных.

Как определить версию?

Чтобы узнать серверную версию следует набрать командный путь: pg_config –version. Также можно прописать: postgres -V. А чтобы определить версию клиента необходима коанда: psql –version. Альтернативное решение sudo -u postgres psql -c ‘Select version ()’ | grep PostgreSQL.

Преимущества базы

Программа популярна. Этому есть много причин:

  • полноценная совместимость SQL;
  • не закрытый исходный код;
  • расширенные настройки, позволяющие делать личные, индивидуальные плагины и проводить персонализацию критериев;
  • можно индексировать геометрические (и по географии) объекты;
  • присутствуют расширения Пост GIS;
  • опция MVCС, чтобы управлять параллельным доступом путем много-версионности;
  • расширяемость, дающая возможность масштабировать посредством сохраняемых процессов;
  • • поддержка определенного объектно-ориентированного функционала.

Помимо этого база регулярно обновляется, что также явное преимущество для пользователей.

Пуск pgAdmin-4 и подсоединение к серверной

PgAdmin-4 будет установлен совместно с базой, для его запуска следует кликнуть на «Меню Пуск затем выбрать непосредственно саму программу и уже после пгАдмин4.

Обновленная версия обладает веб-интерфейсом, потому у пользователя произойдет запуск браузера, где и откроется программа админ4.

Чтобы подключится к только что скаченному и прошедшему процесс установки локальному серверу в серверном обозревателе надо нажать на категорию «PostgreSQL-11».

В итоге будет выполнен запуск «Connect to Server», где потребуется прописать пароль системного пользователя postgres, а именно тот пароль, который был придуман пользователем во время установки программы с базой. После того как введен пароль, нужно поставить галочку «Save Password», это позволит осуществить его сохранение, после чего не потребуется вводить его при каждом входе.

Обязательно подтвердить действие кликом на «OK». В результате будет выполнено подключение к локальной серверной базы.

@YohDeadfall — I understand that part about it, but this is not script that I am creating or even code that I am creating. This is all created under the hood by Npsql/EntityFramework. My quick guess is that I am extending my DbContext from IdentityDbContext<IdentityUser> which wants to create all of the tables for roles, users, claims, etc. If I change this to just extend from DbContext, then everything works as advertised.

Below is the script that EF is trying to use created from dotnet ef migrations script — please be aware that I have removed my custom part of the script for brevity.

You can see there are two specific calls that are being made where [NormalizedName] and [NormalizedUserName] are being used.

Overview

This SQL error generally means that somewhere in the query, there is invalid syntax.
Some common examples:

  • Using a database-specific SQL for the wrong database (eg BigQuery supports DATE_ADD, but Redshift supports DATEADD)
  • Typo in the SQL (missing comma, misspelled word, etc)
  • Missing a sql clause (missed from, join, select, etc)
  • An object does not exist in the database or is not accessible from the current query (eg referencing orders.id when there is no orders table joined in the current query, etc)

In some circumstances, the database error message may display extra detail about where the error was raised, which can be helpful in narrowing down where to look.

Error Message

SQL ERROR: syntax error at or near

Troubleshooting

This should generally be the first step to troubleshoot any SQL syntax error in a large query: iteratively comment out blocks of SQL to narrow down where the problem is.

TIP: To make this process easier, change the group by clause to use position references
eg: group by 1,2,3,4,5 instead of group by orders.status, orders.date, to_char(...)...
as well as separate the where and having clauses onto multiple lines.

So for example, say we have the following query:

play_arrow

WITH cte AS (
select id, status, sales_amountfrom orders
)
select status, foo.date, sum(cte.sales_amount), count(*) from cte
join foo on cte.date = foo.date
group by status, foo.date
order by 3 desc

We could start by running just the portion in the CTE:

play_arrow

-- WITH cte AS (
select id, status, sales_amountfrom orders
-- )
-- select status, foo.date, sum(cte.sales_amount), count(*)
-- from cte
-- join foo on cte.date = foo.date
-- group by 1, 2
-- order by 3 desc

Then strip out the aggregates and portions related to them

play_arrow

WITH cte AS (
select id, status, sales_amountfrom orders
)
select status, foo.date, -- sum(cte.sales_amount), count(*)
from cte
join foo on cte.date = foo.date
-- group by 1, 2
-- order by 3 desc

Iteratively stripping out / adding back in portions of the query until you find the minimum query to trigger the error.

  • Lookup functions and syntax If the query is small enough, or if we’ve narrowed the scope enough with 1, google all the functions used in the query and verify that they exist and are being used correctly.

  • Verify all objects exist Verify that you’ve joined all tables used in the select, where, and having clause, and that those tables exist in the db. Once we’ve narrowed things down from 1, also check that each column exists in the table specified.
