Hi, This may be a really simple question but the answer is eluding me. How do we create in Valentina's SQL a search which includes a lookup of a field in one table does not equal in another table? Think of it like an error checking query. Example: SELECT * FROM t1, t2 WHERE t1.RecID = t2.t1ptr AND NOT t1.field1 = t2.field1 Thanks, Tim Davis VSRV, V4RB
