[Phpmyadmin-devel] Re: Alter Table Lacks Warnings

I recently edited a table for a column change on an enum. The column is not null with a default set and '' is not a member of the enum. This is the output from PHPMyadmin where I changed 'Artist' to 'Music Artist' Table contact_types has been altered. SQL query: ALTER TABLE `contact_types` CHANGE `contact_type` `contact_type` ENUM( 'Actor', 'Actress', 'Music Artist', 'Band', 'Company', 'Unknown' ) NOT NULL DEFAULT 'Unknown' [ Edit ] [ Create PHP Code ] This resulted in all the existing rows that had the value 'Artist' changing to ''. First, I guess I expected that it would change those rows to Music Artist but that's my own fault. Second, the fact that it didn't utilize my default definition ended up "better" than if it had change it to 'Unknown' However, running this from the command line results in the following output: Query OK, 1578 rows affected, 21 warnings (0.06 sec) Records: 1578 Duplicates: 0 Warnings: 21 mysql> show warnings; +---------+------+--------------------------------------------------- ---+ | Level | Code | Message | +---------+------+--------------------------------------------------- ---+ | Warning | 1265 | Data truncated for column 'contact_type' at row 9 | | | | Warning | 1265 | Data truncated for column 'contact_type' at row 11 | | | | Warning | 1265 | Data truncated for column 'contact_type' at row 39 | | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 529 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1533 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1534 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1535 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1536 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1537 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1538 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1539 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1540 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1541 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1542 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1547 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1558 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1568 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1569 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1574 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1575 | | | Warning | 1265 | Data truncated for column 'contact_type' at row | 1576 | +---------+------+--------------------------------------------------- ---+ 21 rows in set (0.00 sec) I believe that the existence of warnings is important and warrants a change in PHPMyAdmin. Thoughts?
