SQL 字符串拆分

字符串拆分：

ALTER FUNCTION [dbo].[f_Split](@sText nvarchar(max),@split NVARCHAR(20))
RETURNS @t TABLE (idx INT IDENTITY(1,1) Primary Key , [value] nvarchar(4000))
AS
BEGIN
    DECLARE @temp NVARCHAR(1000)
 
    WHILE(CHARINDEX(@split,@sText)<>0)   
    BEGIN  
      SET  @temp = SUBSTRING(@sText,1,CHARINDEX(@split,@sText)-1)
      IF(@temp <> 'Empty' AND @temp <> ' ')
        INSERT @t([value]) VALUES (@temp)   
      SET  @sText = STUFF(@sText,1,CHARINDEX(@split,@sText),'')   
    END   
    IF(@sText <> 'Empty' AND @sText <> ' ')
    INSERT @t([value]) VALUES (@sText)   
    RETURN      
END

使用方法：

  DECLARE @HouseCodeStr NVARCHAR(MAX)
  SET @HouseCodeStr ='26a24d5a-9a50-4503-9579-e01c6c01aefd,9980eda0-43da-400e-baf9-2a2e1c7b1dd1,570beb03-99e9-4d8c-8a4f-782cf2428073,ef861f42-ae8b-4045-94c3-eb9907ba643f,35ad978e-9b17-4067-b606-262917a81258,4517b7f6-b0ea-4661-95ab-f36d5d8c82cb,2c606205-9fd9-4d68-a649-2273c5ec0dd8'
  
  SELECT * FROM  f_Split(@HouseCodeStr, ',')
