sql server 2008 將字符串截取成數組

 

今天剛好同事用到了，我就整理出來

sql server 2016 以前都需要自己創建存儲過程，如下

CREATE FUNCTION dbo.F_Split
 (
     @SplitString nvarchar(max),  --源字符串
     @Separator nvarchar(10)=' '  --分隔符號，默認爲空格
 )
 RETURNS @SplitStringsTable TABLE  --輸出的數據表
 (
     [id] int identity(1,1),
     [value] nvarchar(max)
 )
 AS
 BEGIN
     DECLARE @CurrentIndex int;
     DECLARE @NextIndex int;
     DECLARE @ReturnText nvarchar(max);
 
     SELECT @CurrentIndex=1;
     WHILE(@CurrentIndex<=len(@SplitString))
         BEGIN
             SELECT @NextIndex=charindex(@Separator,@SplitString,@CurrentIndex);
             IF(@NextIndex=0 OR @NextIndex IS NULL)
                 SELECT @NextIndex=len(@SplitString)+1;
                 SELECT @ReturnText=substring(@SplitString,@CurrentIndex,@NextIndex-@CurrentIndex);
                 INSERT INTO @SplitStringsTable([value]) VALUES(@ReturnText);
                 SELECT @CurrentIndex=@NextIndex+1;
             END
     RETURN;
 END
GO

使用： 

SELECT * FROM dbo.F_Split('38,33',',')

 

2016以後使用系統自帶的函數

select * from string_split('38,33','，')
