將多列字符串 分割成多行數據

SELECT Name FROM SysObjects Where XType='U' ORDER BY Name --讀取庫中的所有表名 cafe

 --測試數據
IF OBJECT_ID('tempdb..#tab') IS NOT NULL
    DROP TABLE #tab
CREATE TABLE #tab(
id INT,
VALUE VARCHAR(20),
NAME VARCHAR(20)   
)
INSERT INTO #tab
SELECT 1,'12|23','你好,hello' union all
SELECT 1,'456|1|35','Abc,efc,kkk' UNION ALL
SELECT 2,'12','pppp'
--測試數據結束
 select * from #tab
 go
			 CREATE FUNCTION [dbo].[ufn_SplitStringToTable]

			  @str VARCHAR(MAX) ,
			  @split VARCHAR(10)

IF OBJECT_ID('tempdb..#t') IS NOT NULL
    DROP TABLE #t
SELECT a.id AS id_mstr,a.[VALUE],a.name,b.*,identity (int,1,1) as rn into #t FROM #tab a
OUTER APPLY ufn_SplitStringToTable(a.[VALUE],'|') b
IF OBJECT_ID('tempdb..#t2') IS NOT NULL
    DROP TABLE #t2
SELECT a.id AS id_mstr,a.[VALUE],a.name,b.*,identity (int,1,1) as rn into #t2 FROM #tab a

 go
SELECT a.id_mstr,
       a.value,
       a.name,
       a.id  AS value_n,
       b.id  AS name_n
FROM   #t a
       INNER JOIN #t2 b
            ON  a.rn = b.rn
            AND a.id_mstr = b.id_mstr
            AND a.value = b.value

 

這樣就把數據給進行轉換了。 根據字符 | 進行分割出來的
