You can disable an enabled trigger, and enable a disabled trigger.If the procedure is expected to mostly insert new records and rarely update existing ones, then use the following pattern (assuming there are unique constraints on the database to prevent duplicate employees being created): This code relies of the database to tell you the record already exists based on the integrity constraints on the table, which is much more efficient and less error prone that attempting to do it yourself.If the more likely case is that existing records will be updated, the code below is better: begin update employees set ....You might be unaware that a trigger is executing unless it causes an error that is not handled properly. A trigger defined on a schema fires for each event associated with the owner of the schema (the current user).
A trigger defined on a database fires for each event associated with all users.
For other uses of triggers, see table (created in "Creating Tables").
