方法2

  /*--------------------------------

功能说明:  批量DropTable

使用说明:  使用时一定要小心，因为删选表的where条件是like所有必须保证where

后的like确定与你要删除表名相匹配

---------------------------------*/

--------参数定义-------------------

DECLARE @tableName AS Nvarchar(50) --查询表名条件（小心！，确保like条件是你要Drop的表.TableName尽量精确）

SET @tableName='test'  

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

--SELECT name FROM sys.tables   WHERE name LIKE '%'+@tableName+'%' --查询出要删除表的名称

IF @tableName='' SET @tableName='tableName'--初始化TableName为tableName,防止@tableName为空

DECLARE @tableNames AS Nvarchar(3000)

DECLARE @sql AS Nvarchar(3000)

SET @tableNames=

(SELECT ','+name FROM sys.tables   WHERE name LIKE '%'+@tableName+'%'  FOR XML PATH(''))

SET @tableNames= Stuff(@tableNames,1,1,'')

SET @sql='DROP TABLE '+@tableNames

EXEC(@sql)
