In SQL Server 2000 and onwards there are INSTEAD OF triggers that can be used to carry out such tasks. Although these types of triggers can be used in a number of scenarios their primary function is to perform DML operations through such views. This tip shows how to use INSTEAD OF triggers to handle these DML operations on views.

I want to suppress the trigger from firing for a particular statement while it remains in its normal execution state for any of the other statements. Is there any way this can be done dynamically?

Over the years, I have witnessed many developers being confused about when to use data-manipulation language (DML) triggers vs. when to use constraints.

When a value is changed that causes an error, finding what caused the error can be tricky. Here an application was truncating a column. The trigger helped to identify the culprit.

When databases suddenly stop working, it can be for a number of different reasons. Human error plays a large part, of course, and the DBA needs to know what these various humans are up to. DDL triggers can help alert the DBA to unauthorized tampering with a production system, of course, but DDL triggers can't tell you everything. At some point, you will need to implement your own checks. Randy certainly reached that point!

This script generates a audit trigger for each table in the database. The trigger then logs when each table is updated.
