ER_TRUNCATED_WRONG_VALUE: Incorrect datetime value

Question

So i\'ve recently completed an application for a study project. It\'s all good, and all I have left is putting the application to production.

I\'m using MySQL with Node.

Answer 1

Apparently, the datetime value is not a valid MySQL Datetime. But there is a work around modifying the Server SQL Modes.

For some reason, in my development server, the MySQL default mode configurations were completely removed. Therefore there were no restrictions on how I could insert the datetime.

mysql> select @@sql_mode;
    +------------+
    | @@sql_mode |
    +------------+
    |            |
    +------------+
    1 row in set (0.00 sec)

On the production server on the other hand, there was a ton of restrictions that told the mysql server what kinds of datetime formats to accept.

mysql> select @@sql_mode;
+-------------------------------------------------------------------------------------------------------------------------------------------+
| @@sql_mode                                                                                                                                |
+-------------------------------------------------------------------------------------------------------------------------------------------+
| ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+-------------------------------------------------------------------------------------------------------------------------------------------+

This is not a safe method, but I changed the MySQL restriction modes to no_engine_substitution, and voila, everything works like a charm (almost). You have to change the GLOBAL and SESSION modes for this to work.

The standard SQL mode is 'NO_ENGINE_SUBSTITUTION', so we'll put the mode to that. There are more modes you could add tough:

SET GLOBAL sql_mode = '<mode>';
SET SESSION sql_mode = '<mode>';

Now GLOBAL and SESSION mode should be set to NO_ENGINE_SUBSTITUTION

mysql> SET SESSION sql_mode = 'NO_ENGINE_SUBSTITUTION';
mysql> SELECT @@SESSION.sql_mode;
+------------------------+
| @@SESSION.sql_mode     |
+------------------------+
| NO_ENGINE_SUBSTITUTION |
+------------------------+
1 row in set (0.00 sec)

mysql> SET GLOBAL sql_mode = 'NO_ENGINE_SUBSTITUTION';
mysql> SELECT @@GLOBAL.sql_mode;
+------------------------+
| @@GLOBAL.sql_mode      |
+------------------------+
| NO_ENGINE_SUBSTITUTION |
+------------------------+
1 row in set (0.00 sec)

Answer 2

Same answer (given by @Jesper) works for error

ERROR 1292 (22007): Truncated incorrect DOUBLE value: ''

i.e. my

select @@GLOBAL.sql_mode; -- and
select @@SESSION.sql_mode;

gives

STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

When I updated them to

SET SESSION sql_mode = 'NO_ENGINE_SUBSTITUTION';
SET GLOBAL sql_mode = 'NO_ENGINE_SUBSTITUTION';

my SQL inserts executed without a glitch

This error is because of Strict SQL Mode. So Only removing STRICT_TRANS_TABLES from sql_mode is enough. for example

SET SESSION sql_mode = 'ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
