The below example shows how Trigger's can enter into cyclic cascading. 2) The UPDATE Trigger, trigger B on table 'xyz' issues an INSERT on table 'abc'.
This is an efficient way to return a large result set from a function.
For Example: Let's create a table 'product_check' which we can use to store messages when triggers are fired.
Let's create a BEFORE and AFTER statement and row level triggers for the product table.
For Example: The price of a product changes constantly.
It is important to maintain the history of the prices of the products.
