Updating pl sql trigger

In this chapter, we will discuss Triggers in PL/SQL.Triggers are stored programs, which are automatically executed or fired when some events occur.After the T-SQL UPDATE command, we then execute a T-SQL SELECT query to make sure the trigger executed correctly.The output from the UPDATE and SELECT statements are shown below.SQL Server fires triggers on statement rather than row level.For example, if update statement modified 10 rows, create table dbo.DML events are INSERT, UPDATE, or DELETE statements on a table or view.These triggers fire when any valid event is fired, regardless of whether or not any table rows are affected. DDL triggers execute in response to a variety of data definition language (DDL) events.

In the image below we see where we create our example table named tbl Trigger Test with a primary key column named pk ID, a date column named Order Approval Date Time and a varchar column named Order Status.Triggers can be created directly from Transact-SQL statements or from methods of assemblies that are created in the Microsoft .NET Framework common language runtime (CLR) and uploaded to an instance of SQL Server.Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions.The Visual Studio edition that you have and the settings that you use determine these elements.
