Updates and UDF statements

[Paul]

I think I have found a problem with mysql and update statements.

I have a particular UDF function called pcd which returns the first 1
or 2 letters of a postcode (postcode area), it works fine in selects
but when i use it in a update the column being updated ends up with
the first column in the table, 10 spaces, then the 2nd column in the
table, instead of whatever the UDF function returns.

Has anybody else experienced similar problems, im losing my faith in
mysql a bit, im trying to use it for serious business applications but
might have to find an alternative. I prefer linux servers to windows,
any advice, like Max DB?

Thanks,

Paul
