>Yes, but the CursorSchema must match the data types of the fields being returned from the DB. Otherwise, your DB must support CASTing of one data type to another. The order of the field names specified in the schema must also match the order of the field names returned from the DB as well. The field names selected from the DB must match the field names you specify in the CursorSchema.

With the exception of VFP's Logical data type, most of the data I will work with
should be compatible. If the SQL field is varchar, I can live with it, as it should
map fine to a character field in a VFP table. Same with Int to numeric. At least
thats what I'm hoping. Some of the field names would almost certainly change, but
as long as the data types are compatiable, I can't see any reason using CursorSchema
to get back a desired structure table would be a problem.

But, I've been wrong before....
Everything makes sense in someone's mind

In addition, an integer field is not for irrational people
