Hi Edgar,

If I understand you correctly, you want to locate records in Table1 that do not have a matching record in Table2. Is this right?

If so, how about

SELECT * from Table1 Where ID_Field Not In ;
   (Select Distinct ID_Field From Table2) ;
   Into Cursor SomeCursor

Now in the good table I may find 0102, that would match my first 4 digits but I need to continue and see if there is a match for the next digit till the last (in this case of 010200)
