您可以找到这段代码在SQL Server Management Studio的模板资源管理器

--====================================== 
-- Create T-SQL Trigger Template 
--====================================== 
USE <database_name, sysname, AdventureWorks> 
GO 

IF OBJECT_ID ('<schema_name, sysname, Sales>.<trigger_name, sysname, uStore>','TR') IS NOT NULL 
    DROP TRIGGER <schema_name, sysname, Sales>.<trigger_name, sysname, uStore> 
GO 

CREATE TRIGGER <schema_name, sysname, Sales>.<trigger_name, sysname, uStore> 
    ON <schema_name, sysname, Sales>.<table_name, sysname, Store> 
    AFTER <data_modification_statements, , UPDATE> 
AS <T-SQL_statement, , UPDATE Sales.Store SET ModifiedDate = GETDATE() FROM inserted WHERE inserted.CustomerID = Sales.Store.CustomerID> 
GO 

一个简单的例子是

CREATE TRIGGER TriggerName ON TableName 
    AFTER UPDATE 
AS 
    /* Some SQL Statements */ 
    UPDATE TableName 
    SET  ColumnName = 'SomeText' 

GO
