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
