在 SQL 2012 中,我有以下查询:“
DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
-- 指定数据库备份目录
SET @path = 'D:\BACKUP\'
-- 指定文件名格式
SET @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
--SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112) + REPLACE(CONVERT(VARCHAR(20),GETDATE(),108),':','')
DECLARE db_cursor CURSOR FOR
SELECT name FROM master.dbo.sysdatabases WHERE name NOT IN ('master','model','msdb','tempdb') -- exclude these databases
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
BACKUP DATABASE @name TO DISK = @fileName --with differential
FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor "
此查询为数据库进行了备份,但如果我再次运行它,新备份将放置在同一个文件中。我该怎么做才能将新备份放在新的 .bak 文件中?谢谢!!
