Usually, IN query is the fastest in VFP. I wouldn't expect DISTINCT with JOIN to be faster but only test can prove that. You can also try correlated query.

Select * from csrA ;
  WHERE EXISTS ( ;
    SELECT * FROM TableB 
      where TableB.fieldA = TableA.fieldA ;
        TableB.fieldB='101')

In general correlated query in VFP is slower than IN type.

I used distinct on the entire record because, the structures of Tables A & B being different, the query would return a record from csrA whenever it found a macth in TAbleB, theryby repeating records in csrA. Any suggestions would be appreciated.
