转:从SQLSERVER6.5开始,MS提供了一个非常有用的系统存储过程sp_MSforeachtable和sp_MSforeachDB;作为DBA会经常需要检查所有的数据库或用户表,比如:检查所有数据库的容量;看看指定数据库所有用户表的容量,所有表的记录数...,我们一般处理这样的问题都是用游标分别处理处理,比如:在数据库检索效率非常慢时,我们想检查数据库所有的用户表,我们就必须这样写游标: DECLARE @TableName varchar(255) DECLARE @ExeSQL varchar(4000)DECLARE Table_Cursor CURSOR FOR SELECT [name] FROM sysobjects WHERE xtype='U'OPEN Table_Cursor FETCH NEXT FROM Table_Cursor INTO @TableNameWHILE(@@FETCH_STATUS=0) BEGIN PRINT @TableName SELECT @ExeSQL='DBCC CHECKTABLE('''+@TableName+''')' EXEC(@EXESQL) FETCH NEXT FROM Table_Cursor INTO @TableName ENDCLOSE Table_Cursor DEALLOCATE Table_Cursor GO 如果我们用sp_MSforeachtable就可以非常方便的达到相同的目的: EXEC sp_MSforeachtable @command1="print '?'

所以上面的语句也可以这样写:
