such as a data change or change to an object. In SQL Server, there are four types of triggers:DDL Triggers (Data Definition Language), DML Triggers (Data Manipulation Language, CLR Triggers, and Logon Triggers. In this article we will learn about logon triggers ...
Azure SQL Managed Instance Logon triggers fire stored procedures in response to aLOGONevent. This event is raised when a user session is established with an instance of SQL Server. Logon triggers fire after the authentication phase of logging in finishes, but before the user session is establ...
Logon Triggers Logon triggers fire stored procedures in response to a LOGON event. This event is raised when a user session is established with an instance of SQL Server. Logon triggers fire after the authentication phase of logging in finishes, but before the user session is actually estab...
Triggers are database objects that store code and get executed automatically when some type of event occurs, such as a data change or change to an object. In SQL Server, there are four types of triggers:DDL Triggers (Data Definition Language), DML Triggers (Data Manipulation Language, CLR...
SQL Server 2005 Logon Triggers by Frederik Vandeputte as SSCLogon triggers by Cristian Lefter as Simple-talk
Logon triggerswere introduced earlier with the arrival of SQL Server 2005 SP2. It is somewhat similar to the DDL trigger which I had discussed it earlier in my blogs.Hereis the link for it: Some main points regarding Logon Trigger: ...
LOGON Triggers:Similar to DDL Triggers, LOGON Triggers fire stored procedures or T-SQL statements in response to LOGON events. Logon triggers fire after the authentication phase of logging in finishes, but before the user session is actually established. Therefore, all messages originating ...
Before SQL Server fires a logon trigger, SQL Server creates an implicit transaction that is independent from any user transaction. Therefore, when the first logon trigger starts firing, the transaction count is 1. After all the logon triggers finish executing, the transaction commits. As with ...
