INSERT [dbo].[MM_T_MATER] ([fbillno], [fid], [FCREATEDATE], [FDATE], [FPURCHASEORGID], [FENTRYID], [FMATERIALID], [FNUMBER], [F_XHWT_REPNUMBER], [FTaxPrice]) VALUES (N'INC24010057', 113675, CAST(N'2024-01-10T15:30:22.390' AS DateTime), CAST(N'2024-01-10T00:00:00.000' AS DateTime), 100006, 144354, 672265, N'030201064', N'030201064,011401008,011401065,011401066', CAST(5.6000000000 AS Decimal(23, 10)))
INSERT [dbo].[MM_T_MATER] ([fbillno], [fid], [FCREATEDATE], [FDATE], [FPURCHASEORGID], [FENTRYID], [FMATERIALID], [FNUMBER], [F_XHWT_REPNUMBER], [FTaxPrice]) VALUES (N'INC24010057', 113675, CAST(N'2024-01-10T15:30:22.390' AS DateTime), CAST(N'2024-01-10T00:00:00.000' AS DateTime), 100006, 144355, 672270, N'030201082', N'030201082,011401008,011401027,011401066,011401084', CAST(5.3000000000 AS Decimal(23, 10)))

方式一

SELECT a.*
,CASE WHEN a.F_XHWT_REPNUMBER='' THEN a.FNUMBER else b.[fvalue] end FNewValue
FROM 
(
SELECT *,[fvalue]=CAST('<v>'+REPLACE(F_XHWT_REPNUMBER,',','</v><v>')+'</v>' AS xml) FROM MM_T_MATER
) a
OUTER APPLY (
SELECT [fvalue]=T.C.value('.','varchar(50)') FROM a.[fvalue].nodes('/v') AS T(C) 
) b

在这里插入图片描述

方式二

SELECT a.* ,CASE WHEN a.F_XHWT_REPNUMBER='' THEN a.FNUMBER else t.fid end FNewValue
FROM MM_T_MATER a  
OUTER APPLY  fn_StrSplit(a.F_XHWT_REPNUMBER,',') t
