A trigger is a special kind of a store procedure that executes in response to certain action on the table like insertion, deletion or updation of data. It is a database object which is bound to a table and is executed automatically. You can’t explicitly invoke triggers. The only way to do this is by performing the required action no the table that they are assigned to.... |

This month I will expand on last month's column—the foundation of SQL Server™ triggers and the features that they expose. I have targeted this column in response to many of the questions I have received regarding triggers. I'll begin with INSTEAD OF triggers and the differences between them and AFTER triggers. I'll then discuss some situations in which to use INSTEAD OF triggers including allowing updates to multiple tables through views. Finally, I'll discuss how to handle transactions in trigg... |

Implementing business rules as well as performing validation or data modifications, triggers are the best use for this purpose when other methods are not sufficient. Triggers are normally used in two areas: creating audit records and reflecting changes to crucial business tables, and validating changes against a set of business rules coded in T-SQL.
In this article, I would like to demonstrate how to create triggers, use of triggers, different types of triggers and performance considerati... |

I have two triggers defined on my table which are set to fire on the same table actions (i.e. an INSERT, DELETE, UPDATE transaction). The second trigger that fires is dependent on the first fired trigger. How can I make sure that they fire in the correct order to enforce my business logic? In addition, as our system changes, what are some of the caveats that I need to be aware of when managing the trigger firing order? By default, multiple triggers on a SQL Server table for the same action ar... |

A trigger is a database object that is attached to a table. In many aspects it is similar to a stored procedure. As a matter of fact, triggers are often referred to as a "special kind of stored procedure." The main difference between a trigger and a stored procedure is that the former is attached to a table and is only fired when an INSERT, UPDATE or DELETE occurs. You specify the modification action(s) that fire the trigger when it is created.... |

Triggers are one of the core tools available in relational databases such as SQL Server™ 2000. As one of the mainstays of SQL Server database programming, triggers also happen to be one of the topics that I get most of the questions about. In this month's installment of Data Points, I will explore the different trigger types that SQL Server 2000 makes available along with many of the features that they expose. When used properly, triggers can play a key role in a data model and in implementing e... |

Constraints are valuable tools for maintaining data integrity in databases. However, there are times when it is convenient to disable one or more of them to perform tasks such as data synchronization with an offline database. When SQL Server™ replication is used to synchronize data between databases, individual objects can be told to withhold enforcement during replication.... |
