语句如下。蓝色部分表示加筛选，保留这些表，有条件的清空表

--------------------------------------------------------------------------------------------------------------------------

DECLARE @tablename varchar(50)

DECLARE @truncatesql varchar(255)

DECLARE TrCun_Cursor CURSOR FOR

select [name] from sysobjects where type = 'U' and name<>'不想清空的表名' and name<>'不想清空的表名'

OPEN TrCun_Cursor

FETCH TrCun_Cursor INTO @tablename

WHILE(@@fetch_status = 0)

BEGIN

SET @truncatesql = 'truncate table ' + @tablename

--exec(@truncatesql) --当要删除时，去掉exec前的--

PRINT @truncatesql

FETCH TrCun_Cursor INTO @tablename

END

CLOSE TrCun_Cursor

DEALLOCATE TrCun_Cursor
