Hi,
Can I use Group By in Query Extension

Thanks & Regards
Ramesh

you can use that sentence in dynamic sql and you can make it in the following way:
sql_id_1 = sql.parse
("select tccom010.cuno from tccom010" )

The query.extension is added to the "where" clause of the (hidden) select on the main table so you cannot use the group by (this is one of the other clauses of the select statement).
