String Split Ignore Last delimiter if no data
0
I am string splitting some values that are comma delimited into rows.
However some values have an extra comma on the end.
Example
Userid | Value
1 | A,B,C,D,
2 | F,H
Code
select value
from string_split('A,B,C,D,',',')
Current Output
UserId | Value
1 | A
1 | B
1 | C
1 | D
1 |
Is there any way to make the string split function ignore the final comma if no data follows it?
Desired Output
UserId | Value
1 | A
1 | B
1 | C
1 | D

That also removes NULL values. What do you mean by that ?string_splitvalue column will not have null value. And If you pass aNULLvalue tostring_split, it will not return any rows.

So your strings could look like "A,B,,,E,F," and in this instance you'd only want to remove the last blank? If so, maybe just do a check whetherRIGHT(Value, 1) = ','and use a substring of the value, otherwise use the full string.

STRING_SPLIT Function doesn't support for lower version of sql server so first create a function to split the given string and join the function with your select query.Here is below sample for your expected result.
Created User defined Function
CREATE FUNCTION [dbo].[Udf_StringSplit]
(
@Userid INT,
@Value VARCHAR(1000)
)
RETURNS @Result TABLE(
Userid INT,
Value VARCHAR(10)
)
AS BEGIN
DECLARE @Data AS TABLE
(
Userid INT,
Value VARCHAR(100)
)
INSERT INTO @Data(Userid,Value)
SELECT @Userid, @Value
INSERT INTO @Result(Userid,Value)
SELECT Userid,
Split.a.value('.','nvarchar(1000)') AS Value
FROM
(
SELECT Userid,
CAST('<S>'+REPLACE(@Value,',','</S><S>')+'</S>' AS XML) Value
FROM @Data
) AS A
CROSS APPLY Value.nodes('S') AS Split(a)
WHERE Userid=@Userid AND Split.a.value('.','nvarchar(1000)') <>''
RETURN
END
GO
Sample data table
DECLARE @Data AS TABLE(Userid INT , Value VARCHAR(100))
INSERT INTO @Data
SELECT 1,'A,B,C,D,' UNION ALL
SELECT 2,'F,H'
Sql script to get the expected result
SELECT d.Userid,
f.Value
FROM @Data d
CROSS APPLY [dbo].[Udf_StringSplit] (d.Userid,d.Value) AS f
WHERE d.Userid=1
GO
Result
Userid Value
