The original records stay in the table. The result of the SELECT goes to a cursor (a temporary table).

If you want to have the totals in the original table, I think you might start with the SELECT ... GROUP BY to have the totals. After that, you might index the cursor, do a SET RELATION (from the table into the cursor), and do a simple REPLACE. Or write some kind of loop.

>>>So I should sum field "B" by field "A" in the filed "C". I would use 2 do while loops, one of them goes through the table and the other one would sum up the filed B if there are more than two identical ones in field "A". Does it seem ok?
