Thread: BUG #2643: Auto trim on insert and update

The following bug has been logged online:

Bug reference:      2643

Description:        Auto trim on insert and update
Details:

THIS IS NOT A BUG, but a request. Found no place else to submit.
I have found no way to automatically trim fields to the length of the
varchar or char on inserts and updates.
I have tried to create check rules to trim to the varchar length with not
luck.
Can this become a Configuration option???
Doing trims of every variable at every sql command execution takes a lot of
time both coding and lookup the columns length.
Thanks.

Write an explicit cast to varchar(N) or whatever it is.

No, because the behavior is required by the SQL standard.
