在SQlServer下实现某类表批量删除
/*--------------------------------
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)
