如何为 SQL Server 2005 实例中的所有数据库创建 DDL 触发器 [英] How to create DDL trigger to all databases in SQL Server 2005 instance

问题描述

我将为 SQL Server 实例中的所有数据库创建一个 DDL 触发器.我想一次运行而不是为每个数据库运行多次.

I am going to create a DDL trigger to all databases in SQL Server instance. I'd like to do it in one run instead of many runs for each database.

下面是我需要执行的两条 T-SQL 语句:

Below are the two T-SQL statements I need to execute:

-- Create table

use <dbname>
GO
CREATE TABLE dbo.ChangeAttempt
(EventData xml NOT NULL,
AttemptDate datetime NOT NULL DEFAULT GETDATE(),
DBUser char(50) NOT NULL)
GO

-- Create DDL trigger 

use <dbname>
GO
CREATE TRIGGER db_trg_ObjectChanges
ON DATABASE
FOR ALTER_PROCEDURE, DROP_PROCEDURE,
 ALTER_INDEX, DROP_INDEX,
 ALTER_TABLE, DROP_TABLE, ALTER_TRIGGER, DROP_TRIGGER,
 ALTER_VIEW, DROP_VIEW, ALTER_SCHEMA, DROP_SCHEMA,
 ALTER_ROLE, DROP_ROLE, ALTER_USER, DROP_USER
AS
SET NOCOUNT ON
INSERT dbo.ChangeAttempt
(EventData, DBUser)
VALUES (EVENTDATA(), USER)
GO

我的问题是:如何在一次运行中以编程方式创建 DDL 触发器?

My question is: how can I programmaticaly create DDL trigger in one run?

推荐答案

为什么需要一次运行?这是唯一的方法.

why do you need one run? this is the only way to do it.

Msg 111, Level 15, State 1, Line 2
'CREATE TRIGGER' must be the first statement in a query batch.

运行由此产生的输出:

DECLARE @DatabaseName varchar(500)
DECLARE @Database_id  int
DECLARE @Query        varchar(8000)
DECLARE @CRLF         char(2)

SET @CRLF=CHAR(13)+CHAR(10)
---MODIFY THIS TO INCLUDE THE DATABASES THAT YOU WANT TO WORk ON
---MODIFY THIS TO INCLUDE THE DATABASES THAT YOU WANT TO WORk ON
select @Database_id=MIN(database_id) from sys.databases where database_id IN (5,7,8,6)

WHILE @Database_id IS NOT NULL
BEGIN
    SELECT @DatabaseName=name from sys.databases where database_id=@Database_id
    SET @Query='-- Create table'+@CRLF+@CRLF
                +'use '+@DatabaseName+@CRLF
                +' GO'+@CRLF
                +' CREATE TABLE dbo.ChangeAttempt'+@CRLF
                +' (EventData xml NOT NULL,'+@CRLF
                +' AttemptDate datetime NOT NULL DEFAULT GETDATE(),'+@CRLF
                +' DBUser char(50) NOT NULL)'+@CRLF
                +'GO'+@CRLF+@CRLF
                +'-- Create DDL trigger '+@CRLF+@CRLF
                +'use '+@DatabaseName+@CRLF
                +'GO'+@CRLF
                +'CREATE TRIGGER db_trg_ObjectChanges'+@CRLF
                +'ON DATABASE'+@CRLF
                +'FOR ALTER_PROCEDURE, DROP_PROCEDURE,'+@CRLF
                +' ALTER_INDEX, DROP_INDEX,'+@CRLF
                +' ALTER_TABLE, DROP_TABLE, ALTER_TRIGGER, DROP_TRIGGER,'+@CRLF
                +' ALTER_VIEW, DROP_VIEW, ALTER_SCHEMA, DROP_SCHEMA,'+@CRLF
                +' ALTER_ROLE, DROP_ROLE, ALTER_USER, DROP_USER'+@CRLF
                +'AS'+@CRLF
                +'SET NOCOUNT ON'+@CRLF
                +'INSERT dbo.ChangeAttempt'+@CRLF
                +'(EventData, DBUser)'+@CRLF
                +'VALUES (EVENTDATA(), USER)'+@CRLF
                +'GO'+@CRLF
    PRINT @Query
    ---MODIFY THIS TO INCLUDE THE DATABASES THAT YOU WANT TO WORk ON
    ---MODIFY THIS TO INCLUDE THE DATABASES THAT YOU WANT TO WORk ON
    select @Database_id=MIN(database_id) from sys.databases WHERE database_id IN (5,7,8,6) AND database_id>@Database_id
END

编辑
确定要为哪些数据库生成脚本，请执行以下操作:

EDIT
to determine what databases to generate scripts for do the following:

• 运行这个查询:

• run this query:

select database_id,name from sys.databases

select database_id,name from sys.databases

找到您要为其运行脚本的所有数据库

find all of the databases you want to run the scripts for

在两个地方更改我上面的脚本(在循环之前和在循环底部)，以便您想要的所有 database_id 都在以下代码部分中:

change my above script in two places (before loop & at bottom in loop) so all of the database_id that you want are in the following code section:

WHERE database_id IN (AAA,BBB,CCC,DDD,....)

WHERE database_id IN (AAA,BBB,CCC,DDD,....)
