split semicolon delimiter SQL to rows [duplicate]

Answer 1

If you do not like a function, or if you do not have the rights to create a new function, you can use the quite fast XML approach. In your case it needs some extra effort to get this XML-safe (due to special characters and the ; as delimiter):

Declare @Dummy table (ID int, SomeTextToSplit varchar(max))
Insert Into @Dummy values
 (1,'A&B;C;D;E, F')
,(2,'"C" & "D";;D;E, F');

DECLARE @Delimiter VARCHAR(10)=';';
WITH Casted AS
(
    SELECT *
          ,CAST('' + REPLACE((SELECT REPLACE(SomeTextToSplit,@Delimiter,'§§Split$me$here§§') AS [*] FOR XML PATH('')),'§§Split$me$here§§','') + '' AS XML) AS SplitMe
    FROM @Dummy
)
SELECT Casted.*
      ,x.value('.','nvarchar(max)') AS Part 
FROM Casted
CROSS APPLY SplitMe.nodes('/x') AS A(x)

The result

1   A&B
1   C
1   D
1   E, F
2   "C" & "D"
2   
2   D
2   E, F
