Sql Server: Split Function

An article by Fabry19dice Commenti

 

Ecco una funzione in Sql Server per splittare una stringa:

CREATE FUNCTION dbo.fnSplit(
 @sInputList VARCHAR(8000) -- List of delimited items
 , @sDelimiter VARCHAR(8000) = ',' -- delimiter that separates items
) RETURNS @List TABLE (item VARCHAR(8000))

BEGIN
DECLARE @sItem VARCHAR(8000)
WHILE CHARINDEX(@sDelimiter,@sInputList,0) <> 0
 BEGIN
 SELECT
 @sItem=RTRIM(LTRIM(SUBSTRING(@sInputList,1,CHARINDEX(@sDelimiter,@sInputList,0)-1))),
 @sInputList=RTRIM(LTRIM(SUBSTRING(@sInputList,CHARINDEX(@sDelimiter,@sInputList,0)+LEN(@sDelimiter),LEN(@sInputList))))
 
 IF LEN(@sItem) > 0
 INSERT INTO @List SELECT @sItem
 END

IF LEN(@sInputList) > 0
 INSERT INTO @List SELECT @sInputList -- Put the last item in
RETURN
END
GO
--Test
select * from fnSplit('1,22,333,444,,5555,666', ',')
select * from fnSplit('1##22#333##444','##') --note second item has embedded #
select * from fnSplit('1 22 333 444 5555 666', ' ')
