SQL SERVER 数据库备份详细代码
本文实例为大家分享SQL SERVER数据库备份的具体代码，供大家参考，具体内容如下
/**
批量循环备份用户数据库，做为数据库迁移临时用
*/
SET NOCOUNT ON
DECLARE @d varchar(8)
DECLARE @Backup_Flag NVARCHAR(10)
SET @d=convert(varchar(8),getdate(),112)
/***自定义选择备份哪些数据库****/
–SET @Backup_Flag=’UserDB’ — 所用的用户数据库
SET @Backup_Flag=’AlwaysOnDB’ — AlwaysOn 用户数据库
CREATE TABLE #T (ID INT NOT NULL IDENTITY(1,1),SQLBak NVARCHAR(MAX) NOT NULL)
IF @Backup_Flag=’UserDB’
BEGIN
INSERT INTO #T (SQLBak)
SELECT
‘BACKUP DATABASE [‘ + name + ‘] TO DISK=”E:\Backup\’ + NAME + ‘_Full_’+@d+’.bak” WITH CHECKSUM,NOFORMAT,INIT,SKIP,COMPRESSION’ AS ‘SQLBak’
FROM sys.databases
WHERE database_id>4
END
IF @Backup_Flag=’AlwaysOnDB’
BEGIN
INSERT INTO #T (SQLBak)
SELECT
‘BACKUP DATABASE [‘ + database_name + ‘] TO DISK=”E:\Backup\’ + database_name + ‘_Full_’+@d+’.bak” WITH CHECKSUM,NOFORMAT,INIT,SKIP,COMPRESSION’ AS ‘SQLBak’
FROM sys.availability_databases_cluster
END
DECLARE
@Minid INT ,
@Maxid INT ,
@sql VARCHAR(max)
SELECT @Minid = MIN(id) ,
@Maxid = MAX(id)
FROM #T
PRINT N’–打印备份脚本……….’
WHILE @Minid <= @Maxid
BEGIN
SELECT @sql = SQLBak
FROM #T
WHERE id = @Minid
—-exec (@sql)
PRINT ( @sql )
SET @Minid = @Minid + 1
END
DROP TABLE #T
