Hi Silvia:
From this posting I'm not sure which DB scheme you are using.
There are many different approaches to use, most Databases
have field descriptions which contain sizes:
example: in Mysql char(30)
One could query the database description, then parse
the field/column description.
So, first tell us what DB interface you're using.
