字符串 分割和合并

分割多个字段，然后拼接在一起

    SELECT pg.vchcode,pg.ptypeid,pg.ktypeid,pg.dlyorder,pg.pgdetail,pg.IsCut,(CAST(substring(pg.pgQtyStr,b.number,charindex('ǒǜ' ,pg.pgQtyStr +'ǒǜ',b.number)-b.number) AS NUMERIC(22,10))) AS lpgQtyStr,
            dbo.fn_splitPgCode(pgIDCode,'ǒǜ',len(STUFF('ǒǜ'+ pgQtyStr,b.number+2,LEN(pgQtyStr),''))-len(replace(STUFF('ǒǜ'+ pgQtyStr,b.number+2,LEN(pgQtyStr),''), 'ǒǜ', ' '))-1) lpgIDCode
            INTO #pg  FROM (SELECT * FROM dbo.pgdlyDetail WHERE  vchcode = @ovchcode and dlyorder = @nOldDlyOrder ) pg
                join master..spt_values b on b.type='P'
                where charindex('ǒǜ','ǒǜ'+pg.pgQtyStr ,b.number)=b.number
                 AND pgQtyStr <>'' AND pgQtyStr <> '-'    

效果如下

字符串分割方法

if object_id ('dbo.fn_splitPgCode') is not null
    drop function dbo.fn_splitPgCode
go

CREATE FUNCTION fn_splitPgCode(
@s   varchar(8000),
@splitchar VARCHAR(5),
@num  INT
)RETURNS VARCHAR(1000)
AS
BEGIN
 Declare @s1 varchar(1000)
 SET @s1 = '-'
 SELECT @s1 = col FROM dbo.f_splitSTR(@s,@splitchar) WHERE id = @num
 RETURN @s1    
END
go

SET QUOTED_IDENTIFIER ON
SET ANSI_NULLS ON
GO


CREATE FUNCTION f_splitSTR(
@s   varchar(8000),   --待分拆的字符串
@split varchar(10)     --数据分隔符
)RETURNS @re TABLE(ID int IDENTITY,col varchar(8000))
AS
BEGIN
    DECLARE @splitlen int
    SET @splitlen=LEN(@split+'a')-2
    WHILE CHARINDEX(@split,@s)>0
    BEGIN
        INSERT @re VALUES(LEFT(@s,CHARINDEX(@split,@s)-1))
        SET @s=STUFF(@s,1,CHARINDEX(@split,@s)+@splitlen,'')
    END
    INSERT @re VALUES(@s)
    RETURN
END


GO

合并

SELECT pgs.PtypeId,pgs.KtypeId,pgs.pgDetail,SUM(pgs.pgDetail) sumqty
,stuff((select 'ǒǜ'+convert(varchar(25), g.pgIDCode) FROM (SELECT pggoodsidcodes.* FROM dbo.pggoodsidcodes
    WHERE pggoodsidcodes.PtypeId='00009' AND pggoodsidcodes.KtypeId='00002' AND pggoodsidcodes.pgDetail<>0 AND IsUsed=0 AND lockMode='D'
    ) g WHERE g.PtypeId = pgs.PtypeId AND g.KtypeId=pgs.KtypeId AND g.pgDetail=pgs.pgDetail AND g.goodsorderid=pgs.goodsorderid AND g.IsCut=pgs.IsCut
    FOR XML PATH('')), 1,2, '') as CustomerName
FROM dbo.pggoodsidcodes pgs
where pgs.PtypeId='00009' AND pgs.KtypeId='00002'
AND IsUsed=0 AND lockMode='D'
GROUP BY pgs.PtypeId,pgs.KtypeId,pgs.pgDetail,pgs.goodsorderid,IsCut

效果如下
