博客中,Insus.NET有分享过处理重复记录的功能。如《删除重复Row记录数据》https://www.cnblogs.com/insus/p/10890148.html
今天就改编这个,改为动态存储过程。日后可以针对任一张表来进行。
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author: Insus.NET -- Blog: https://insus.cnblogs.com -- Create date: 2019-05-31 -- Update date: 2019-05-31 -- Description: 删除多个重复记录 -- ============================================= CREATE PROCEDURE [dbo].[usp_Delete_Multiple_Duplicate_Record] ( @TABLE_NAME SYSNAME, @Refer_Column_lists NVARCHAR(MAX) -- ‘[a],[b],[c]‘ ) AS BEGIN DECLARE @query NVARCHAR(MAX) = N‘ ;WITH cte_temp_table(rank_num,‘+ @Refer_Column_lists +‘) AS ( SELECT ROW_NUMBER() OVER(PARTITION BY ‘+ @Refer_Column_lists +‘ ORDER BY ‘+ @Refer_Column_lists +‘) AS rank_num, ‘+ @Refer_Column_lists +‘ FROM ‘+ @TABLE_NAME +‘ ) DELETE FROM cte_temp_table WHERE rank_num > 1; ‘ EXECUTE sp_executeSql @query END
演示:
IF OBJECT_ID(‘tempdb.dbo.#Part‘) IS NOT NULL DROP TABLE #Part CREATE TABLE #Part ( [ID] INT, [Item] NVARCHAR(40) ) GO INSERT INTO #Part ([ID],[Item]) VALUES (23394,‘I32-GG443-QT0098-0001‘), (45008,‘I38-AA321-WS0098-0506‘), (14350,‘K38-12321-5456UD-3493‘), (64582,‘872-RTDE3-Q459PW-2323‘), (23545,‘098-SSSS1-WS0098-5526‘), (80075,‘B78-F1H2Y-5456UD-2530‘), (53567,‘PO0-7G7G7-JJY098-0077‘), (44349,‘54F-ART43-6545NN-2514‘), (36574,‘X3C-SDEWE-3ER808-8764‘), (36574,‘RVC-43ASE-H43QWW-9753‘), (14350,‘K38-12321-5456UD-3493‘), (64582,‘872-RTDE3-Q459PW-2323‘), (80075,‘B78-F1H2Y-5456UD-2530‘), (53567,‘PO0-7G7G7-JJY098-0077‘), (44349,‘54F-ART43-6545NN-2514‘), (44349,‘54F-ART43-6545NN-2514‘), (36574,‘X3C-SDEWE-3ER808-8764‘) GO EXECUTE [dbo].[usp_Delete_Multiple_Duplicate_Record] #Part,‘[ID],[Item]‘ SELECT * FROM #Part
