MySQL 'Truncated incorrect INTEGER value'

Question

I\'m getting an odd \'Truncated incorrect INTEGER value\' error when I run the following UPDATE query:

update tbl
set projectNumber = right(comments, 7)
wher         


        

Answer 1

Toby Speight has outlined one solution for the problem in his answer. I don't know if anybody will ever be as stupid as me, but to whom it may concern:

I got Error code 1292 trying to modify the data type of a column IsDeleted from VARCHAR ('Y' => true, 'N' => false) to BIT.

To resolve the problem: Update all 'Y's to '1's (UPDATE table SET isDeleted = '1' WHERE isDeleted = 'Y') and all 'N's to '0's, tried to modify the column type again and voila data type was modified PLUS the '1'-columns contain TRUE and vice-versa now.

Answer 2

It's not an error. It's a warning that comes from CONVERT() when you ask it to convert non-numeric to integer;

Run these queries in console to see:

mysql> SELECT CONVERT(right('1s23d45678', 7), SIGNED INTEGER);
+-------------------------------------------------+
| CONVERT(right('1s23d45678', 7), SIGNED INTEGER) |
+-------------------------------------------------+
|                                               3 |
+-------------------------------------------------+
1 row in set, 1 warning (0.00 sec)

mysql> SHOW WARNINGS;
+---------+------+----------------------------------------------+
| Level   | Code | Message                                      |
+---------+------+----------------------------------------------+
| Warning | 1292 | Truncated incorrect INTEGER value: '3d45678' |
+---------+------+----------------------------------------------+
1 row in set (0.00 sec)

As I said, it's a warning, not an error. Your query should be doing the update correctly.

Answer 3

Another common cause for this warning is white space in the string to be converted. Use trim() before convert() to get rid of that.

Answer 4

As stated in other answers, this is an error as of 2019, which prevents the query from running. To run the query even if there are strings that cannot be converted to numbers, simply use UPDATE IGNORE.

So for example a minimal version of the original code:

UPDATE IGNORE tbl
SET projectNumber = RIGHT(comments, 7)
WHERE CONVERT(RIGHT(COMMENTS, 7), SIGNED INTEGER) > 0

Answer 5

If you're using a text type for column data and you tried to set the default value as 0 then just set it as NULL:

ALTER TABLE `__table__` 
CHANGE `__column_name__old__` `__column_name__new__` 
INT(4) NOT NULL DEFAULT '0';

Answer 6

I found one solution, which is out of box and could easily be implemented. The solution is much similar to SET ANSI_WARNING OFF in MS SQL Server.

In MySQL, first you need to check whether what is configurations is set for "sql_mode" by using below command:

SHOW VARIABLES LIKE 'sql_mode';

OR else use below:

SELECT @@GLOBAL.sql_mode;

There might have following sets of value in CSV.

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

Based on your error, you can remove settings and Reset it using below command:

SET GLOBAL sql_mode = 'ONLY_FULL_GROUP_BY,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

By using above command to reset it. It has solved similar of this problem "Truncated incorrect INTEGER value" in my case. I hope it should be working from other user also who are facing this issue.

For more details on this "sql_mode", please refer this.

Hope this would be use full!
