SQL Server 2012 Comma-Separated String Splitting: An XML-Based Solution
SQL Server 2012's compatibility level can restrict access to the STRING_SPLIT
function. This article presents an effective workaround using XML techniques to split comma-separated values.
Leveraging XML and CROSS APPLY
This method transforms the comma-separated string into an XML structure. CROSS APPLY
then extracts each value as a node from this XML. Here's the SQL code:
SELECT Split.a.value('.', 'NVARCHAR(MAX)') AS DATA FROM ( SELECT CAST('<X>'+REPLACE(@ID, ',', '</X><X>')+'</X>' AS XML) AS String ) AS A CROSS APPLY String.nodes('/X') AS Split(a);
Illustrative Example
Let's use these sample parameters:
DECLARE @ID NVARCHAR(300)= '1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20'; DECLARE @Marks NVARCHAR(300)= '0,1,2,5,8,9,4,6,7,3,5,2,7,1,9,4,0,2,5,0';
The following query demonstrates splitting these strings and inserting the results into a table:
INSERT INTO @StudentsMark SELECT C.id, C1.marks FROM CTE C LEFT JOIN CTE1 C1 ON C1.RN = C.RN;
Outcome
The result is a table with 'id' and 'marks' columns, each populated with the split values from @ID
and @Marks
.
This XML-based approach offers a reliable method for handling comma-separated data in SQL Server 2012, bypassing compatibility level limitations.
