User variables do not work with REGEXP under MySQL 4.0.21 & 4.1.5.
Is this a bug or a feature?
It's difficult to provide an answer to this because you're providing
no information about what "do not work" means. Can you be more
specific?
Sure. I didn't want to write to not mess in case this is a feature.
So here goes my test case:
SELECT
@a:=FIRMLEGALZIPCODE
FROM tCustomers
WHERE @a REGEXP "[0-9]"
-> Empty set (0.03 sec)
You're expecting the value to be selected first so that you then can
test it with the WHERE clause later.
SELECT
@a:=FIRMLEGALZIPCODE
FROM tCustomers
WHERE FIRMLEGALZIPCODE REGEXP "[0-9]";
-> 2803 rows in set (0.03 sec)
