自動備份SQL Server資料庫中使用者建立的Stored Procedures

為了避免意外遺失/損壞辛苦建立的Stored Procedures，或是想要還原到先前版本的Stored Procedures，這樣提供了一個有效方法，可以自動將指定資料庫中的Stored Procedures進行備份。

1. 在特定的資料庫（建議為SQL Server的master資料庫）上建立資料表StoredProceduresBackup，用來保存備份的Stored Procedures。

IF OBJECT_ID('StoredProceduresBackup') IS NOT NULL

DROP TABLE StoredProceduresBackup

GO

CREATE TABLE StoredProceduresBackup

(

AutoID INTEGER IDENTITY(1,1) PRIMARY KEY,

InsertDate DATETIME DEFAULT GETDATE(),

DatabaseName

VARCHAR(50),

ProcedureName VARCHAR(50), ProcedurebaseName VARCHAR(50), ProcedureName

ProcedurebaseName VARCHAR(4000

)

2. 建立Stored Procedure名為usp_ProceduresVersion，該Stored Procedure用來將需要備份Stored Procedures的備份到上述所建立的資料表中。

其中主要存取sysobjects和syscomments系統表：

(1) sysobjects system table
Contains one row for each object (constraint, default, log, rule, stored procedure, and so on) created within a database. In tempdb only, this table includes a row for each temporary object.

(2) syscomments system table
Contains entries for each view, rule, default, trigger, CHECK constraint, DEFAULT constraint, and stored procedure. The text column contains the original SQL definition statements, which are limited to a maximum size of 4finition statements, which are limited to a maximum size 45. .

(3) source script of stored procedure.

/*

Name: usp_ProceduresVersion

Description: Back up user defined stored-procedures

Author: Rickie

Modification Log: NO

Description Date Changed By

Created procedure 8/27/2004 Rickie

*/

CREATE PROCEDURE usp_ProceduresVersion @DatabaseName NVARCHAR(50)

AS

SET NOCOUNT ON

--This will hold the dynamic string.

DECLARE @strSQL NVARCHAR(4000)

--Set the string

--Only stored procedures

SET @strSQL = 'INSERT INTO master.dbo.StoredProceduresBackup(

DatabaseName,ProcedureName,ProcedureText )

SELECT ''' + @DatabaseName + ''', so.name, sc.text

FROM ' + @DatabaseName + '.dbo.sysobjects so

INNER JOIN ' + @DatabaseName + '.dbo.syscomments sc

ON so.id = sc.id

WHERE so.type = ''p''' + ' and so.status>0

Order By so.id '

--Execute the string

EXEC dbo.sp_executesql @strSQL

GO

3. 建立Job執行上述Stored Procedure

在SQL Server上建立Job，並設定運行計劃，這樣指定資料庫的Stored Procedures就可以自動備份到上述資料表中。
