Question
if you are running a query that inserts a new set of records in a table from other one, there is a way to force the update of the coincident pk record in the destination table, without deleting records or split the process in two others (insert new and update existing)?
Solution
In Firebird 2.1, you can do Update or Insert
UPDATE OR INSERT INTO T1 (F1, F2)
VALUES (:F1, :F2)
MATCHING (F1);
