SQL2005EXPress自动备份

STEP1：在数据库服务器的master表中创建存储过程sp_BackupDatabase

代码如下

 USE [master]
 GO
 /****** 对象:  StoredProcedure [dbo].[sp_BackupDatabase]    脚本日期: 04/09/2019 09:38:30 ******/
 SET ANSI_NULLS ON
 GO
 SET QUOTED_IDENTIFIER ON
 GO

 CREATE PROCEDURE [dbo].[sp_BackupDatabase]
        @databaseName sysname, @backupType CHAR(1)
 AS
 BEGIN
        SET NOCOUNT ON;   

        DECLARE @sqlCommand NVARCHAR(1000)
        DECLARE @dateTime NVARCHAR(20)   

        SELECT @dateTime = REPLACE(CONVERT(VARCHAR, GETDATE(),111),'/','') +
        REPLACE(CONVERT(VARCHAR, GETDATE(),108),':','')    

        IF @backupType = 'F'
                SET @sqlCommand = 'BACKUP DATABASE ' + @databaseName +
                ' TO DISK = ''F:\SQLExpressAutoBackup\' + @databaseName + '_Full_' + @dateTime + '.BAK'''   

        IF @backupType = 'D'
                SET @sqlCommand = 'BACKUP DATABASE ' + @databaseName +
                ' TO DISK = ''F:\SQLExpressAutoBackup\' + @databaseName + '_Diff_' + @dateTime + '.BAK'' WITH DIFFERENTIAL'   

        IF @backupType = 'L'
                SET @sqlCommand = 'BACKUP LOG ' + @databaseName +
                ' TO DISK = ''F:\SQLExpressAutoBackup\' + @databaseName + '_Log_' + @dateTime + '.TRN'''   

        EXECUTE sp_executesql @sqlCommand
 END  

STEP2：创建SQL文本，代码如下：保存成backup.sql文件即可

 exec [sp_BackupDatabase] 'WeightCommon','F'
 go  

STEP3：创建批处理文件，以下代码保存成SQLRun.bat即可

@ECHO OFF 

SET dbhost=MS-20161018OMFZ\SQLEXPRESS
SET dbuser=sa
SET dbpasswd=sasa
set dbName=master
SET sqlpath=%~dp0
set sqlfile=Backup.sql

osql -S %dbhost% -U %dbuser% -P %dbpasswd% -d %dbName% -i %sqlpath%%sqlfile%

ECHO 完成!
PAUSE

@ECHO Done!

效果如下：
