Hi rajemessage,
To change your funtion inline, you can reference the below sample.
ALTER FUNCTION DBO.udfa(@aa int)
RETURNS TABLE
AS
RETURN
SELECT
STUFF(
SELECT ''+L FROM XYZ WHERE id= @aa FOR XML PATH('')
),1,0,'') AS L,
stuff(
SELECT ''+B FROM XYZ WHERE id= @aa FOR XML PATH('')
),1,0,'') AS B
GO
--test
CREATE TABLE xyz (ID INT, L VARCHAR(99),B VARCHAR(99));
INSERT INTO xyz(ID,L,B) SELECT 1,'A','D'
UNION ALL
SELECT 1,'B','C'
UNION ALL
SELECT 2,'C','B'
UNION ALL
SELECT 2,'D','A'
SELECT * FROM XYZ
GO
SELECT * FROM udfa(1)
More on the
STUFF and FOR XML PATH
If you have any question, feel free to let me know
