Mariadb 10.4 Data truncated for column 'column_name' on insert but not on update

Question

I have the following table (mariadb 10.4) called p:

 +----------------+----------------------------------------------------------------------------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+----------------------------------------------------------------------------------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | description | text | YES | | NULL | | | url | text | YES | | NULL | | | source | enum('source_a','source_b','source_c','source_d','source_e') | YES | | NULL | |

I currently have a couple of million rows on this table with the sources a, b, c, and d. Just recently we applied a migration to add source_e and we started getting the error ERROR 1265 (01000): Data truncated for column 'source' at row 1 when trying to inset a row with the source_e. The used command that yields the error is the following:

INSERT INTO p (description, url, `source`) VALUES ('test', 'https://google.com.br', 'source_e');

Insertions with any of the other sources are still working.

The behavior changes when editing a row that is already on the db, the error is not shown:

UPDATE `p` SET `source`='source_e' WHERE `id`='3'; Yields: Query OK, 1 rows affected (0.001 sec)

Is there a way to debug this scenario? I've tried changing the log level of the db to get a better insight on the problem ( SET GLOBAL log_warnings=3; ) but the error message did not change.

I also tried changing the source_e name to source_e_ , the error persisted.

Btw, i did change the name of the fields to comply with company policies.

Answer 1

It turns out it was my bad. We happen to have a trigger on insertions of this table that feeds a materialized view kind of table. All I had to do was add 'source_e' to the source field on the other table.
