Split String with Comma Separated Delimiter and Convert to Table Rows in SQL Server

Nov 18, 2015
Introduction

Here I will explain how to split string with comma delimited character in SQL Server or split string with comma separated delimiter in SQL Server or split string with special character in SQL Server or split and convert comma separated or delimited string to table in SQL Server.

Description:


To split comma separated string in SQL Server we need to write custom method for that we need to create one function like as shown below

Custom Split function to split comma separated string into table


CREATE FUNCTION dbo.Split(@String nvarchar(4000), @Delimiter char(1))
RETURNS @Results TABLE (Items nvarchar(4000))
AS
BEGIN
DECLARE @INDEX INT
DECLARE @SLICE nvarchar(4000)
-- HAVE TO SET TO 1 SO IT DOESNT EQUAL Z
--     ERO FIRST TIME IN LOOP
SELECT @INDEX = 1
WHILE @INDEX !=0
BEGIN
-- GET THE INDEX OF THE FIRST OCCURENCE OF THE SPLIT CHARACTER
SELECT @INDEX = CHARINDEX(@Delimiter,@STRING)
-- NOW PUSH EVERYTHING TO THE LEFT OF IT INTO THE SLICE VARIABLE
IF @INDEX !=0
SELECT @SLICE = LEFT(@STRING,@INDEX - 1)
ELSE
SELECT @SLICE = @STRING
-- PUT THE ITEM INTO THE RESULTS SET
INSERT INTO @Results(Items) VALUES(@SLICE)
-- CHOP THE ITEM REMOVED OFF THE MAIN STRING
SELECT @STRING = RIGHT(@STRING,LEN(@STRING) - @INDEX)
-- BREAK OUT IF WE ARE DONE
IF LEN(@STRING) = 0 BREAK
END
RETURN
END

Once we create custom function Split() run sample query like as shown below


SELECT items FROM [dbo].[Split] ('861,739,10,1670', ',')

Once we run above query we will get output like as shown below

Output
