[Zope] sqlvar

I have noticed that I get ODBC errors if I attempt to insert character strings longer than the database field length. I can restrict the character lengths by using the maxlength attribute in the data entry forms, but would it not be better to have an attribute of sqlvar that restricts the length of strings being passed to the ODBC adapter? ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz
