Hi guys,
I use the following code to detect alphanumeric strings:
IF _my_variable SIMILAR TO '^[a-zA-Z0-9]+$' THEN
// do stuff here
END IF;
In pg8.4 this worked perfectly. I upgraded to pg9.0 and it no longer
works. From the release notes it appears that the behavior of SIMILAR
TO has changed in pg9.0. My question is, how do I modify my code so
that it works in 9.0?
Thanks in advance.
Rommel.
