Hello,

How do I insert a record into a column, if that record does not already exist.
If it does exist, then do nothing:

----------------------------------------------------------------------
INSERT INTO _table (_item) VALUES ('001') ..... ?

If _item 001 does not exist, then insert it, else do nothing.
----------------------------------------------------------------------

Please note that _item IS NOT a primary key, but I can't have duplicates there.

I'm using mysql 5.1.


Thanks,
Rick
