You cannot have ID=0 if ID is an index.

Yikes! Then how do I update this table? I will need to update every variable
*except* the ID, which is the primary key and an auto_increment.

RE: Update Doesn't Update!
If ID column is primary key and auto increment as you said, it cant be equal
to zero.
You got a query which reads:
UPDATE columns WHERE false
There is no chance for any updates.

Of course you can have ID=0.

Impossible to say, until you let us know how you defined the column in the
first place...

You can, but not if it's an auto-increment field.

Quoting cars...@bitbybit.dk: Of course you can have ID=0. Definately agree mysql DESCRIBE test; +-+-+--+-+-++ | Field | Type| Null | Key | Default | Extra | +-+-+--+-+-++ | autoinc | int(11) | NO | PRI | NULL| auto_increment | | value | varchar(10) | NO | | NULL|| +-+-+--+-+-++ 2 rows in set (0.00 sec) mysql SELECT * FROM test; +-++ | autoinc | value | +-++ | 0 | 1234567890 | +-++ 1 row in set (0.00 sec) mysql UPDATE test SET value='a' WHERE autoinc='0'; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql SELECT * FROM test; +-+---+ | autoinc | value | +-+---+ | 0 | a | +-+---+ 1 row in set (0.00 sec) However, what I believe the problem is: mysql UPDATE test set value='12345678901' WHERE autoinc='0'; Query OK, 1 row affected, 1 warning (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 1 mysql SELECT * FROM test; +-++ | autoinc | value | +-++ | 0 | 1234567890 | +-++ 1 row in set (0.00 sec) the value of value is too long for the varchar(10) in the table. It thus generates the warning, and truncate the field. The poster's table needs to be updated therefor to accept longer variables in the sizes column. -- Regards, Chris. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Sorry. It's an enum of which the elements I am trying to add into a row are
elements of the same enum; that is, a subset.

You're using the wrong type. RTFM re. the difference between enums and

You cannot have ID=0 if ID is an index.
You can, but not if it's an auto-increment field.
Also, not *entirely* correct, although you have to jump through a few hoops:
it can occur if the field was changed to auto_increment *after* the 0 was
put in there.
Yes, I inherited a database like that once, and yes, it fucks up your day.

I'm lost. I set up this database originally with auto_increment and the
first value was 0. I thought that was always the case. Is there a problem
here?

For autoincrement fields, both NULL and 0 are magic values to get the next number from the sequence at insert time.
