This has come up somewhere before (maybe here?) - is there a standard
way to get a "cursor structure" from a query without actually running
the query? I know VFP does it by tacking on "WHERE 0=1", but that
seems kludgey. do all (good) db's support some sort of
prepare/pre-compile/pre-something that would give you a clue what the
result was going to look like?
It depends on the dbapi adapter. MySQLdb returns the structure even
without the data, but others, such as pysqlite, do not. What backend
were you using?
MySQL - got that in the ZipCode Demo where zipcodes.cstateprov = 'xx'
+ python SimpleFormWithBizobj.py
