MariaDB Error 1629: Field Comment Exceeds Length
Description
MariaDB Error 1629 indicates that a comment provided for a table field during a `CREATE TABLE` or `ALTER TABLE` operation has exceeded its maximum allowed length. The error message specifies the field name and the maximum permissible length in bytes. This prevents the DDL statement from completing successfully.
Error Message
Comment for field '%s' is too long (max = %lu)
Known Causes
3 known causesDefault Comment Length Exceeded
The specified comment for a table field surpassed MariaDB's internal maximum length limit, typically 255 characters (bytes) for MyISAM and InnoDB tables.
Multi-byte Character Encoding
Using multi-byte character sets (e.g., UTF-8) for comments can cause a seemingly short string to exceed the byte limit, as each character might consume more than one byte.
Unintended Long Text Input
Copying and pasting a lengthy description or comment into the field definition without checking its length can easily trigger this error.
