Oracle triggers if inserting updating

Now before updating ’empid’ column in ’emp’ table see the ’emp’ and ’emp_backup’ table records.Vishwanath Dalvi is a gifted engineer and tech enthusiast. When not hacking around or supporting the open source community, he is trying to overcome his phobia of dogs.

However if the trigger actions reference other tables, the trigger is not dropped or modified if those other tables are dropped or modified.

Triggers are removed using the DROP TRIGGER statement.

The UPDATE, DELETE, and INSERT statements within triggers do not support the full syntax for UPDATE, DELETE, and INSERT statements.

Note that the sqlite3_changes() and sqlite3_total_changes() interfaces do not count INSTEAD OF trigger firings, but the count_changes pragma does count INSTEAD OF trigger firing.

Assuming that customer records are stored in the "customers" table, and that order records are stored in the "orders" table, the following UPDATE trigger ensures that all associated orders are redirected when a customer changes his or her address: CREATE TABLE customer( cust_id INTEGER PRIMARY KEY, cust_name TEXT, cust_addr TEXT ); CREATE VIEW customer_address AS SELECT cust_id, cust_addr FROM customer; CREATE TRIGGER cust_addr_chng INSTEAD OF UPDATE OF cust_addr ON customer_address BEGIN UPDATE customer SET cust_addr=NEW.cust_addr WHERE cust_id=NEW.cust_id; END; Causes the customer.cust_addr field to be updated for a specific customer entry that has customer.cust_id equal to the $cust_id parameter.

An ON CONFLICT clause may be specified as part of an UPDATE or INSERT action within the body of the trigger.
