刪除指定SQL資料庫所有表和儲存過程
阿新 • • 發佈：2019-02-06
原理就是根據 sysobjects 系統表裡面查到每張表名，然後drop掉，同理可以一次性drop所有儲存過程
--刪所有資料表 USE [資料庫名] DECLARE @tableName VARCHAR(Max) SET @tableName = '' SELECT @tableName = @tableName + NAME + ',' FROM sysobjects WHERE xtype = 'U'; SELECT @tableName = 'drop table ' + LEFT(@tableName, (LEN(@tableName)-1)) EXEC (@tableName) --刪所有儲存過程 USE [資料庫名] DECLARE @procedureName VARCHAR(Max)
補充：sysobjects表裡type欄位含義：
--刪所有資料表 USE [資料庫名] DECLARE @tableName VARCHAR(Max) SET @tableName = '' SELECT @tableName = @tableName + NAME + ',' FROM sysobjects WHERE xtype = 'U'; SELECT @tableName = 'drop table ' + LEFT(@tableName, (LEN(@tableName)-1)) EXEC (@tableName) --刪所有儲存過程 USE [資料庫名] DECLARE @procedureName VARCHAR(Max)
