I would like to aggregate single column values with an separator in between and with some prefix. Below is the code tried which works.
SELECT concat('TNB/IAG/',STRING_AGG(WF_ValStr, '/')) AS Result
FROM wfattrdata where wf_id=35262472 and WF_AttrID in (28,29,30,31,33);
I could get the below expected result in latest MSSql versions.
TNB/IAG/1/2/3/4/5
How to replace the above query to make it work in SQL Server 2016?
Check the below STUFF,XML code -
SELECT DISTINCT CONCAT('TNB/IAG/',T1.results) AS EXPECTED_RESULT FROM
(
select REPLACE(STUFF(CAST((
SELECT ' /' +CAST(c.WF_ValStr AS VARCHAR(MAX))
FROM (
SELECT distinct WF_ValStr
FROM wfattrdata
) c
FOR XML PATH(''), TYPE) AS VARCHAR(MAX)), 1, 2, ''),' ','') AS results
from wfattrdata t) T1;
