SQL 2005 Introduces DDL Triggers

Normally you use the trigger functionality with Data Manipulation Language (DML) commands such as INSERT, UPDATE, and DELETE. Now SQL 2005 introduces new Data Definition Language (DDL) triggers. You can use it to audit schema changes.

Example of DDL Trigger:

        
        CREATE TRIGGER safety 
        ON DATABASE 
        FOR DROP_TABLE, ALTER_TABLE 
        AS 
            PRINT 'You must disable Trigger "safety" to drop or alter tables!' 
            ROLLBACK
        ;        

        DISABLE TRIGGER safety ON DATABASE;

Please refer to MSDN for details: MSDN: Designing DDL Triggers
