Hi Roddy

i need to create a procedure that delete .

when i delete a name from the table the coulmn (Is Here) which takes values (true / false)
changes its value to false as the name is no longer in the table

also

i need to save these deleted records in another table . this new table works as abackup

can u help ? & as for the rest forget about it

Thank u

This makes no sense as if you "delete" the row you cant update the is here field since it would no longer be there. If thats the case then make a trigger thats before delete.

For mysql I think its something like this: This should copy the row you are deleting to the old/current table and put it in the new table and then delete the row from the old/current table.

DROP TRIGGER trig1;

DELIMITER //
CREATE TRIGGER trig1
BEFORE DELETE ON old_table FOR EACH ROW
BEGIN
INSERT INTO new_table select from old_table WHERE current_id=OLD.current_id;
END;
//
DELIMITER ;
