How to find out what triggers you have.

I try to avoid using triggers because I always forget they are there.  I have been burned more than once by triggers updating data when I didn’t know they were there.  I have also been troubleshooting someone else’s database and been bitten by triggers.
The code from this post I copied from Chris McGowan’s blog.  He wrote up a great article about trigger status.  His post has code to create a job to email you. 
I modified it to just run in SSMS and use a table variable (in case you don’t have the permissions to create a temp table).

This script runs against master and will tell you about all triggers in all databases.

Use master


-- Create table variable
DECLARE @TriggerStatus as Table
(
      DatabaseName SYSNAME,
      TableName VARCHAR(255), 
      TriggerName VARCHAR(255),
      TriggerStatus VARCHAR(8)
);
-- Insert triggers
INSERT INTO @TriggerStatus
EXEC sp_msforeachdb
'
IF ''?'' NOT IN (''master'', ''model'', ''msdb'', ''tempdb'', ''distribution'', ''reportserver'', ''reportservertempdb'')
BEGIN
USE [?]; 
SELECT  DB_NAME() AS DatabaseName,
        OBJECT_NAME(parent_id) AS TableName,
        name AS TriggerName,
        CASE is_disabled
          WHEN 0 THEN ''Enabled''
          ELSE ''Disabled''
        END AS TriggerStatus
FROM    sys.triggers WITH ( NOLOCK )
WHERE   is_ms_shipped = 0
        AND parent_class = 1;
END'


SELECT DatabaseName, TableName, TriggerName,  TriggerStatus FROM   @TriggerStatus
