Hi! I have a table with 19000 rows which needs to updated and accessed by different threads.
One approach to avoid locking the table as much is to create a TABLE TEMP mytable and as last action in threads to move rows from mytable_tmp to mytable, like this: BEGIN TRANSACTION; CREATE TEMP TABLE mytable_tmp ... INSERT INTO mytable_tmp SELECT * FROM mytable; COMMIT TRANSACTION; BEGIN TRANSACTION; UPDATE mytable_tmp SET... COMMIT TRANSACTION; BEGIN TRANSACTION; DELETE FROM mytable; INSERT INTO mytable SELECT * FROM mytable_tmp; DROP TABLE mytable_tmp; COMMIT TRANSACTION; Or is there a better way? Can the last transaction be achieved quicker? Are indices in mytable automatically updated? The PRIMARY KEY in mytable keeps incrementing can it be resetted or should I DROP mytable? Many thanks for any pointers... Regards, /Karim
