Today, I will be continuing my talk on database objects that can be viewed through the system catalog views or system stored procedures. A Microsoft SQL Server database is composed of many different objects.
We will be investigating how to retrieve information on these objects in the [MATH] sample database. Please see [...]
Triggers can be used to track Data Manipulation Language (DML) changes that occur in tables. Today, I am going to expand the AUTOS database script to add table auditing. Auditing is a very good practice when multiple people have rights to make changes to important semi-static data. This is not a good [...]
Another usage of Database Triggers is track Data Definition Language (DDL) changes that occur in a database. Today, I am going to enhance the AUTOS database script to add such auditing. This auditing is a very good practice when multiple people have syadmin rights to make such changes.
First, I am going [...]
Another usage of Data Modification Language (DML) triggers is the replicating data for historical tracking or data aggregation.
Today, I am going to expand on the AUTOS database that I created in prior articles to demonstrate such usage. The business unit has asked us to track each macro task in the making of [...]
A typical use of Data Modification Language (DML) triggers is to prevent unwanted data modification. AFTER triggers are great at detecting the INSERT, UPDATE or DELETE action and rolling back the changes.
A good security model can prevent these types of changes and should be the first line of defense. However, there [...]
