Also, triggers will fire only in response to logged operations. Minimally logged operations such as TRUNCATE and WRITETEXT do not cause a trigger to fire.

However, you should not use triggers in place of declarative referential integrity (DRI) via a FOREIGN KEY constraint. DRI is enforced when the modification is made, before the change is part of the table, and is much more efficient than executing trigger code. However, you cannot define FOREIGN KEY constraints across databases. To enforce referential integrity across databases, you must use triggers.

INSERTED and DELETED tables are visible only within a trigger and cannot be accessed by any other construct such as a stored procedure or function. The structure of the INSERTED and DELETED tables exactly matches the column definition of the table on which the trigger was created. Therefore, you can reference columns by using the same name as the table for which the trigger was defined. When you execute an INSERT operation, the INSERTED table contains each row that was inserted into the table, whereas the DELETED table does not contain any rows. When you execute a DELETE statement, the DELETED table contains each row that Create GS1 - 13 In Java Using Barcode printer for Java Control to generate, create EAN13 image in Java applications. www.OnBarcode.comEAN 128 Encoder In None Using Barcode printer for Microsoft Word Control to generate, create UCC - 12 image in Word applications. www.OnBarcode.comLesson 3: Implementing Triggers

When you execute an UPDATE statement, the INSERTED table contains the after image of each row you updated, and the DELETED table contains the before image of each row that you updated. The before image is simply a copy of the row as it existed before you executed the UPDATE statement. The after image reflects the data in the row after the UPDATE statement has changed appropriate values. The general Transact-SQL syntax for creating a DML trigger is as follows: Make UPC-A In Objective-C Using Barcode drawer for iPhone Control to generate, create UPC Symbol image in iPhone applications. www.OnBarcode.comRead ECC200 In None Using Barcode scanner for Software Control to read, scan read, scan image in Software applications. www.OnBarcode.comCREATE TRIGGER [ schema_name . ]trigger_name ON { table | view } [ WITH <dml_trigger_option> [ ,...n ] ] { FOR | AFTER | INSTEAD OF } { [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] } [ WITH APPEND ] [ NOT FOR REPLICATION ] AS { sql_statement [ ; ] [ ,...n ] | EXTERNAL NAME <method specifier [ ; ] > } <dml_trigger_option> ::= [ ENCRYPTION ] [ EXECUTE AS Clause ] Every trigger must have a name that conforms to the rules for object identifiers. You use the ON clause to specify the table or view that the trigger will be created against. If the table or view is dropped, any triggers that were created against the table are also dropped. Using the WITH clause, you can do the following: Specify whether the code in the trigger will be encrypted when it is created. Specify an execution context. The FOR clause specifies whether the trigger is an AFTER or INSTEAD OF trigger as well as the event(s) that cause the trigger to fire. You can specify more than one event for a given trigger if you choose. Most people can ignore the WITH APPEND clause, which applies only to 65 compatibility mode, because most organizations should have upgraded their SQL Server 6.5 databases by now. The NOT FOR REPLICATION clause is covered in 19, Managing Replication. Following the AS clause, you specify the code that you want to execute when the trigger is fired.
