Subject: str_aggr function not wokring
Hi,
I need to combine results of multiple rows in one row. I get below error. Could you please help.
Query:
select string_agg((select '******' || P.PhaseName || ' - ' || R.Recommendation AS "ABC" from tblAssessmentRecommendation R,tblAssessmentPhases P
where R.PhaseID = P.PhaseID Order BY P.sortOrder DESC),' ')
Error:
ERROR: more than one row returned by a subquery used as an _expression_ SQL state: 21000
Regards,
Aditya.
Hi,
I would suggest you to try something like this instead
select string_agg( '******' || P.PhaseName || ' - ' || R.Recommendation '' ORDER BY P.sortOrder DESC ) AS "ABC"
from tblAssessmentRecommendation R,tblAssessmentPhases P
where R.PhaseID = P.PhaseID
Regards,
Patrick
Thanks Patrick. I used WITH Query and feeded that output to string_aggr which worked. However it is giving performance issues. Will check on that. THanks.
