>Select * From Table1 where MatchKey IN (Select MatchKey From Table2)

having trouble with the actual sql syntax.

select * from table1 where field1 = .t. into resulttable

now only want the rows from resulttable that have a match on field2 and field3 in table2.

obviously i would prefer to get both things done in a single statement, if possible. this is just the easiest way for me to explain it.

thanks brenda
