Sql error ora 01722 неверное число

Have you gotten an “ORA-01722 invalid number” error? I’ll explain what this error is and how you can resolve it in this article.

ORA-01722 Cause

The ORA-01722 error is caused by trying to convert a string into a number. It could be because of an invalid numeric character in your expression, or you’re trying to add a text value into a number column.

You’ve run an SQL query (which can be SELECT, INSERT, UPDATE, for example), and you’ve got this error:

ORA-01722: invalid number

The reason for this error is that Oracle has attempted to convert a string into a number, but could not perform the conversion.

For example, converting the value of “Hello” to a number cannot be done.

A valid number contains these characters:

• Digits 0 to 9
• Possibly a decimal point
• A + or – sign
• An E or e character

The error can appear in the following queries:

SELECT TO_NUMBER('123,100') FROM dual;

SELECT 'DatabaseStar' - 2016 FROM dual;

There are a few ways to resolve this error, so let’s take a look.

The solution to the “invalid number” error message could be one of several things:

• An incorrect character or typo in your query
• Bad data in your database
• An issue with the query logic

1 – Mismatch of Data Types in an Insert Query

Are you trying to INSERT data into a table using INSERT INTO VALUES?

If so, check that your columns are aligned to your values. I mean, make sure that the position of the columns that contain numbers match the numbers you’re trying to insert.

This query will produce an error (assuming that score is a number):

INSERT INTO student_results (student_id, subject_name, score, comments)
VALUES (1, 'Science', 'Pretty good', 95);

I’ve got the columns around the wrong way here. To correct the query, I need to move the score value of 95 to in between the subject name and comments.

INSERT INTO student_results (student_id, subject_name, score, comments)
VALUES (1, 'Science', 95, 'Pretty good');

2 – Inserting or Updating using a Subquery

Are you inserting or updating values in a table using a subquery?

This error can be harder to detect, because you’re not explicitly stating the values to be inserted.

The error occurs because one of the values found in the subquery is trying to be inserted into a numeric column, and the value is not a number.

To find the cause of the error, you can run the subquery by itself and add a WHERE condition:

WHERE UPPER(column) != LOWER(column)

Replace the “column” with the column you suspect has the bad data. The UPPER and LOWER functions will return different values from character strings, and you should be left with the rows that have string values.

If you want to dig further, or if that doesn’t work:

1. Run the subquery by itself to see the results
2. Look at the values in the columns you’re expecting to be numeric to identify any that look like obvious characters.
3. If you can’t easily tell, you can perform a TO_NUMBER on the columns to find the error.
4. If this doesn’t help, try getting a DISTINCT list of each column in the subquery, and then performing a TO_NUMBER.
5. You can also use a WHERE clause to restrict the results of the subquery, so you’re only looking at a small data set at a time.

Once you’ve found the value that causes the issue, you can either update the bad data, or update your query to handle this data.

3 – Implicit Conversion in a Select Statement

Are you getting this “ORA-01722 invalid number” error when running a SELECT statement?

There are a few reasons for this error:

1. Implicit conversion in WHERE clause
2. Invalid format mask when using TO_NUMBER

In most cases, it is due to an implicit conversion in a WHERE clause. An implicit conversion is where a value is being converted by Oracle but you didn’t specify it.

To resolve this, check for a numeric column that’s being compared to a character column.

For example:

SELECT ...
WHERE number_col = varchar_col;

This will result in an implicit conversion of the VARCHAR column to a number, which may cause the invalid number error.

If you’re using the TO_NUMBER function in your query, make sure that the format mask includes acceptable characters.

The earlier example would cause an error.

4 – Other Possible Solutions

There are some other solutions to this error:

• Fields that contain spaces cannot be converted, so ensure that you TRIM this data, convert it to NULL or zero.
• The database formats for numbers are mismatched between two databases. For example, European numeric data uses 12.345,67 where US format is 12,345.67. Review your NLS_LANG settings to ensure this isn’t causing any issues.
• A function-based index on the table could be causing the error. Review your table to see if there are any function-based indexes that could be converting data.

So, that’s how you resolve the ORA-01722 invalid number error in Oracle!

Using Oracle database is very common but sometimes due to some uncertain reasons, you may get ORA-01722 invalid number error. Do you want to know what is ORA-01722 invalid number error and how to resolve ora-01722 invalid number error? If you want to know so then I must say that you have come to the right place. I am saying so because here I am going to mention some best ways to fix ORA-01722 error in Oracle.

Now, let’s get started with the introduction of this error, causes and then the ways to fix ora-01722 invalid number error and so on…..

What Is ORA_01722 Invalid Number Error?

ORA-01722 invalid number error is actually a fairly typical error in Oracle database. It is an invalid number error that occurs during a failure when you convert a character string to a valid number. It is an error that occurs due to arithmetic operation in the statement failed to calculate just because a single operand cannot be implicitly converted to a valid number. This error can take place due to several reasons which are further mentioned in this blog, so do not skip going through this blog.

Causes Of Occurring ORA-01722 Invalid Number Error

Several causes are that can lead you to face ORA-01722 invalid number error. However, some of the major causes are as follows:

Cause #1: Error During String Concatenation

If you use a plus (add) sign then it cannot concatenate strings. So, if you are using a wrong sign to concatenate two strings then you can get ORA-01722 invalid number error. Below is the code you might have tried to concatenate two strings:

SQL> set heading off;
SQL> select ‘Today is ‘ + sysdate from dual;
select ‘Today is ‘ + sysdate from dual
*
ERROR at line 1:
ORA-01722: invalid number

Here, SQL parser thought the statement tried to make arithmetic operation, however, it failed to continue. The right ways to concatenate two strings are as follows:

SQL> select ‘Today is ‘ || sysdate from dual;

Today is 26-DEC-19

The output of this code is perfect in concatenating two strings.

Cause #2: Error During Type Conversion

When you create a simple table that contains only one column with NUMBER type with the below code:

SQL> create table salaries (salary number);

Table created.

If you try to insert a row into the table that contains NUMBER column, you may get ORA_01722 error with the below code:

SQL> insert into salaries (salary) values (‘200,000’);
insert into salaries (salary) values (‘200,000’)
*
ERROR at line 1:
ORA-01722: invalid number

You may get this error because the value ‘200,000’ of column SALARY can’t be converted into a valid number. You can make it easier by just removing the comma separator:

SQL> insert into salaries (salary) values (‘200000’);

1 row created.

When it comes to fixing ORA_01722 invalid number error, you can try several ways but the best options you can try are further mentioned here. All these solutions are very easy to try and are the most effective and working ways:

Fix #1: Insert Or Update Using a Subquery

If you are inserting or updating values in a table by using a subquery then you can get this error. This error can be quite difficult to detect because you are not explicitly stating the values to be inserted. You get this error because sometimes even one of the values found in the subquery is trying to be inserted into some numeric column. Also, the value is not a number.

Well, to find the major causes of this error, you can try running the subquery by itself and you can add a WHERE condition as mentioned below:

WHERE UPPER(column) != LOWER(column)

Here, you can replace the column with the column you found has the bad data. Here, the UPPER and the LOWER functions will return the different values from character strings and then you will be left with the rows that have strings values.

If you want to dig further then you can follow the below steps:

• You can run the subquery by itself to check the results.
• You can look at the values in the column you are expecting to be numeric to identify any that look like the same characters.
• You can also perform a TO_NUMBER on the columns to find the error.
• Also, you can get a DISTINCT list of each column in the subquery and then you can perform a TO_NUMBER.
• Apart from this, you can use a WHERE clause to restrict the results of the subquery and so you are just looking at a small data set at a time.

After you found the value that causes this error, you can either update the bad data or you can update the query to properly handle this data.

Fix #2: Mismatch Of Data Types In An Insert Query

If you are trying to INSERT data into a table with the use of INSERT INTO VALUES?

If yes then you can check that the columns are aligned to the values you want. It means that you have to make sure that the position of the columns that used to contain numbers that you are trying to insert.

The below query will then produce ORA-01722 invalid number error:

INSERT INTO student_results (student_id, subject_name, score, comments)

VALUES (1, ‘Science’, ‘Pretty good’, 95);

After this query, you will get the columns around the wrong way and in order to correct the query, you have to move the score value of 95 to in between the comments and the subject name.

INSERT INTO student_results (student_id, subject_name, score, comments)

VALUES (1, ‘Science’, 95, ‘Pretty good’);

Fix#3:  Convert Implicitly In a Select Statement

If you are getting the error ‘ora-01722 invalid number’ when you are running a SELECT statement there would be two possible reasons:

• Invalid format mask while using TO_NUMBER
• Convert implicitly in WHERE clause

In some cases, this error takes place due to implicit conversion in a WHERE clause. An implicit conversion is where a value is being converted by Oracle but you do not specify it.

However, in order to fix this issue, you have to check for a numeric column that is being compared to a character column. As for example:

SELECT …

WHERE number_col = varchar_col;

This code insertion will result in an implicit conversion of the VARCHAR column to a number which may also cause the invalid number error.

However, if you are using the TO_NUMBER function in the query, you have to make sure that the format mask includes acceptable characters.

Fix #4: Some Common Possible Fixes

Apart from the above fixes, you can try these other possible ways to fix ORA-01722 invalid number error. Here are the other possible fixes you can try:

• The database formats for numbers are mismatched between these two databases. As for example, European numeric data uses 12.345,67 where US format is 12,345.67. You can review the NLS_LANG settings to make sure that it is not causing any problem.
• Fields that used to contain spaces cannot be easily converted, so it is important to make sure that you TRIM this data. After that, you convert it to NULL or also can convert it to ZERO.
• It is possible that a function-based index is causing ORA_01722 invalid number error. You can review the table to see if there are any function-based indexes that could be converting the data.

In my previous article i have given the brief introduction about different errors like ORA-12154: TNS listener error  and ORA-00600 which is related to internal error codes.The third most searched Error for oracle is ORA-01722 Error which is Invalid Number error. This error is searched approximately 25 k times per month in google search engine.In this article i will try to explain you why this error will come and how this error will solve.You will get this error while converting non numeric string to number or while inserting string value or character value in to number column.

“ORA-01722 error will be searched approximately 25 k times per month on google.”

Why ORA-01722 error will come?

This is another common error the SQL and PL SQL developers  and DBAs will face.This error will come in oracle for mismatching the datatype as number to string or trying to insert the string value in to number values.There should be different reasons for this error.I will mention some scenarios in which this error will come.

Situation 1 :

When user tries to convert string value to number value.

To explain this scenario i will take a simple example. I will try to convert the string in to number using TO_NUMBER function.

Query :

select to_number(‘XYZ’) from dual;

Output :

Error at line 1:

ORA-01722: invalid number

Situation 2:

When user tries to insert the string value in to number column.

Query:

create table Employee
(rollno number(10));

insert into Employee
values(1);
commit;

select * from Employee;

insert into Employee
values(‘amit’);
commit;

Output :

Error at line 1:

ORA-01722: invalid number

The ORA-01722 error will come when you try to convert the string value in to number.

Situation 3 :

Query :

create table Test111
(no1 varchar2(10));

insert into Test111
values(‘1′);
commit;

insert into Test111

values(’10’);
commit;

insert into Test111
values(‘a’);
commit;

select * from Test111 where no1 between 0 and 10;

Output :

Error at line 1:

ORA-01722: invalid number

Resolution of the Error :

I have given the basic scenarios of producing the ORA-1722 error.This error will come when we tries to convert the string value in to number using to_number function. The string can not be converted to number.So to resolve the error we need to use number value in to_number function.

Resolution 1 :

 Use number value in to_number function.

Query :

select to_number(‘111’) from dual;

Output :

111

Always use number value (for varchar2 column) in to_number function to convert that value to number.

Resolution 2 :

Check description of table and change the column to varchar2 column if you want to insert the varchar2 value in the column.

Query :

Alter table Employee

modify rollno varchar2(10);

insert into Employee
values(‘amit’);
commit;

1 Record inserted

So to resolve this error we need to find out the number column from the table and change it to varchar2 column.After altering the column we will be able to insert varchar datatype values.

Oracle SQL Error [1722] [42000]: ORA-01722: invalid number (runs well on SQL Developer) #6513

System information:

• Windows 10 pro (EN)
• DBeaver 6.1.4
• Without additional extensions

Connection specification:

Describe the problem you’re observing:
Running a query were I’m multiplying 2 varchar (one of them converted to_numeric) returns me the error «SQL Error [1722] [42000]: ORA-01722: invalid number». The same query runs well on SQL Developer.

Columns configuration:

Columns on query:

Execution of the same query in SQL Developer:

org.jkiss.dbeaver.model.sql.DBSQLException: SQL Error [1722] [42000]: ORA-01722: invalid number

Caused by: java.sql.SQLSyntaxErrorException: ORA-01722: invalid number

The text was updated successfully, but these errors were encountered:

Generally it works fine in DBeaver
SELECT to_number(‘123’) * ‘3’ FROM dual
shows 369 in results. So problem is definitely not in multiplying numbers. Perhaps some of varchars is not actually a number.

try to find
select option_3 from _table_ where not REGEXP_LIKE(option_3, ‘^[ ]*[+,-]*[0-9]*[.]?[0-9]*$’)

Thanks for your reply @cerebel and @serge-rider

I taked the suggestion from @cerebel but for field option_4. And I got all the table rows returning on query result. This happened because the numbers were saved with comma instead of dot for decimal separator.

I know that this is not a normal and «valid» operation (multiplying numerics with varchars), but why it works on Oracle SQL Developer and in DBeaver returns error? The Oracle Connection Driver is the same.

the difference might be in language settings. sqldeveloper changes many oracle session options that affect how numbers/dates are interpreted.

@jpfmeneses about dot/comma of decimal separator — checks
select * from v$nls_parameters where parameter =’NLS_NUMERIC_CHARACTERS’
oracle say v10 by example
NLS_NUMERIC_CHARACTERS =»decimal_character group_separator»
so, find which application changes nls_param.. ( try sqplus, sqlDevelopper, dbeaver)
In dbeaver:queryManger (enable all options in preferences/general/queryMangery:queryTypes, and open view of queryManger)- this param is not changed.

@cerebel thanks for your feedback.

SQL Developer:

I went into Dbeaver to run that query first, after that opened the SQL Developer and go back to Dbeaver and verified that the parameter stayed with the same values, but different from SQL Developer. There is any DBeaver option that I can consider to change this parameter?

@jpfmeneses will set [,] as decimal separator (at session level)
databaseNavigator->editConnection ->connectionSettings-> initialization->bootstrapQueries
ALTER SESSION SET NLS_NUMERIC_CHARACTERS=’,.’
or execute upper sql, in editor ..

src
In SQL Developer, Preferences->Database-> NLS, if you change the Decimal Separator setting, you also need to make sure that your new setting doesn’t conflict with the existing Group Separator setting.
In this case, you needed to change Decimal Separator to a period ., but also change the Group Separator setting from a period to a comma , to avoid a setting conflict.
or, in editor, run upper sql ..

Better to redefine which decimal separator will be used in yours option_X columns, because at database level — it is [.], not [,] .

How to Resolve ORA-01722: invalid number

ORA-01722

ORA-01722 means that the arithmetic operation in the statement failed to calculate because one of operands cannot be converted to a valid number implicitly.

Let’s see some error patterns.

A. Type Conversion

We created a simple table containing only one column with NUMBER type.

SQL> create table salaries (salary number);

When we tried to insert a row into the table containing NUMBER column, we got ORA-01722.

SQL> insert into salaries (salary) values ( ‘200,000’ );
insert into salaries (salary) values (‘200,000’)
*
ERROR at line 1:
ORA-01722: invalid number

1. Make it Easier to Convert

This is because the value ‘200,000’ of column SALARY cannot be converted into a valid number. We should make it easier to be converted, so we remove the comma separator.

SQL> insert into salaries (salary) values ( ‘200000’ );

Unsurprisingly, string ‘200000’ can be converted to a number and inserted into the table.

2. Use VARCHAR2

You cannot always depend on unpredictable implicit conversion, sometimes, you should change the column from NUMBER into VARCHAR2 . For example, phone numbers of customers may not be perfectly formatted as NUMBER .

SQL> insert into customers (cust_id, phone_number) values (100, ‘0254 539 2413’);
insert into customers (cust_id, phone_number) values (100, ‘0254 539 2413’)
*
ERROR at line 1:
ORA-01722: invalid number

As we can see, the value of phone number cannot be converted into a NUMBER , so we should use VARCHAR2 instead.

SQL> alter table customers modify phone_number varchar2 (13);

SQL> insert into customers (cust_id, phone_number) values (100, ‘0254 539 2413’);

B. String Concatenation

Using a plus (add) sign can not concatenate strings.

SQL> set heading off;
SQL> select ‘Today is ‘ + sysdate from dual;
select ‘Today is ‘ + sysdate from dual
*
ERROR at line 1:
ORA-01722: invalid number

SQL parser thought your statement was trying to do an arithmetic operation, but the string ‘Today is ‘ failed to be converted into number. The correct way to concatenate strings is to use || , not a plus sign + .

SQL> select ‘Today is ‘ || sysdate from dual;

Today is 26-DEC-19

As a result, the output is perfect in concatenating a string and a date without ORA-01722.

A very similar error that you might see in your PL/SQL codes is ORA-06502: PL/SQL: numeric or value error, which is also related to conversion issues of numeric values.

Ошибка ORA-01722: неверное число или ORA-01722: inval >

Обычно ошибка возникает при загрузки данных из текстового файла с помощью Oracle Sqlloader. Ошибка связана с тем, что в России разделитель целой и дробной часть запятая, а в США и Европе – точка.

Если попытаться загрузить в базу некорректно отформатированные данные, то Oracle их не поймет. Выйти из этого положения можно несколькими способами. Некоторые проще, некоторые сложне. Давайте рассмотрим их. Вначале простые, к концу более сложные и, возможно, чреватые проблемами.

1. Зайти в файл и заменить все точки на запятые. Например

1|New York|NY|7322564|1|2001|8307|-73.943849000|40.669800000|
заменяем на

Тут всеп просто. Никаких подводных камней, кроме того, что точки могут встречаться не только в числах и это надо отслеживать, иначе испортите данные.

Например в Linux это легко сделать с помощью sed (для Windows можно взять отсюда или использовать, скажем, perl). Команда не создает резервной копии.

sed -i ‘s/./,/g’ filename.txt

2. В локальном файле при загрузке данных установить соответствующие параметры NLS.

Например, если загрузка осуществляется следующим скриптом батником:

sqlldr scott/[email protected] control=us_citiesus_cities.ctl data=us_citiesus_cities.dat

то ошибки можно избежать с помощью выполнения предварительно в bat-файле вот такой команды:

set nls_lang=american_america.CL8MSWIN1251
sqlldr scott/[email protected] control=us_citiesus_cities.ctl data=us_citiesus_cities.dat

Я считаю этот вариант наиболее предпочтительным.

3. Если это Windows, то можно изменить глобальные настройки NLS. Сделать это можно в реестре в веточке

Нужно будет вместо значения RUSSIAN_RUSSIA.CL8MSWIN1251 прописать AMERICAN_AMERICA.CL8MSWIN1251.

Это решение может очень сильно повлиять на систему в целом. Действие этого параметра может повлечь неработоспособность другого приложения.

Я запустил sql-запрос в oracle sql-разработчике, и он работает отлично, но когда я использую оболочку, в данном случае adodb в excel vba, для выполнения того же запроса я получаю сообщение об ошибке. Я подозреваю, что adodb использует другую версию oracle, и оптимизация выполняется по-разному.

Я выполнил запрос: select (LATITUDE) from db where sin(LATITUDE)

Я получаю сообщение об ошибке:

ORA-01722: неверный номер

ORA-02063: предыдущая строка из db

Если я изменяю sin(LATITUDE) в запросе:

LATITUDE (он не работает)

LATITUDE (он работает)

sin(LATITUDE) (он не работает)

to_number(sin(LATITUDE)) (он не работает)

sin(to_number(LATITUDE)) (он не работает)

Я также попробовал придать LATITUDE плавучесть, и это тоже не сработает. Единственный экземпляр, где он выполняется, — это без SIN и с одинарными кавычками вокруг плавающего значения справа от условия.

Я в недоумении относительно того, почему я не могу заставить запрос работать без каких-либо ошибок, хотя он отлично работает в Oracle SQL Developer. Любая помощь будет оценена по достоинству.

Таким образом, кажется, что LATITUDE хранится как число, а некоторые из значений не являются числовыми.

Возможно, такой запрос поможет вам разобраться в проблеме:

Это не идеальный тест, но он часто работает.

Лучший метод использует регулярные выражения:

Следуя следствию в комментариях, это, по-видимому, является разницей в настройке NLS между прямым SQL-клиентом и ADODB-соединением. Поскольку вы храните число в виде строки (которая всегда является плохим идеей), а число имеет десятичный разделитель, разные настройки NLS_NUMERIC_CHARACTERS вызывают ошибку в одном месте, но не в другом.

Oracle использует этот параметр NLS при неявном преобразовании из строки в число или если у вас есть явный to_number() без маски формата. Поэтому в любой среде одно из этих операторов будет работать, а другое получит ошибку ORA-01722:

Который не работает, зависит от настройки NLS. Вы можете использовать явную маску формата, чтобы избежать этого, и третий параметр to_number() чтобы сказать, как его интерпретировать:

Это использует маркер разделителя D дециметров, который соответствует первому символу в переопределении NLS — обратите внимание, что переключатель периода и запятой между этими двумя операторами — и что переопределение NLS должно быть установлено в соответствии с вашими фактическими данными. Вам также необходимо использовать соответствующие цифры цифр до и после десятичной точки.

В предположении, что вы имеете дело с десятичными градусами, вы должны иметь возможность использовать:

Вам действительно нужно только два девятки перед десятичной точкой для широты, но вам понадобятся три по долготе, поэтому вы также можете быть последовательными.

Но вам также нужно сделать это явное преобразование везде, где вы ссылаетесь на него, например:

Этого можно было бы избежать, если бы вы использовали правильный тип данных в первую очередь. Если вы не можете изменить тип столбца, вы можете подумать о добавлении виртуального столбца, который делает для вас такое же преобразование, или если этому не разрешено представление, которое изменяет тип.

Более ранний ответ дал вариацию Гордону Линоффу, но оказался красной селедкой.

ORA-01722: неправильный номер

Причина:

Пробное преобразование символьной строки в числовую провалилось, потому что символьная строка не была правильной числовой литерой. Только числовые поля или символьные поля содержащие числовые данные могут быть использованы в арифметических функциях или выражениях. Только числовые поля могут быть добавлены или вычтены из данных.

Действие:

Проверьте символьные строки в функции или в выражении; убедитесь в том, что они содержат только числа, знаки, десятичные точки, и символ «E» или «e», затем повторите операцию.
