I'm making a program that will import data from several foxpro databases to mysql and i am using a single data source.
The problem is that sometimes an item exists and sometimes it doesn't, is there a way to verify if an item exists ? if i try to access the item and it doesn't exist it throws an exception and the execution of the program stops but i would just like it to skip that one item and continue with the rest. How can that be accomplished? thank you.

Hi Mauricio,

if by item you mean a field in your foxpro DB, then you can simply
encapsulate your access to this item in a when exception/do nothing/end

Best regards
