Hello all. I'm new to informix and I'm testing the SP routines.

how can achieve to bypass the "A subquery has returned not exactly one row." message when I'm building the SP:

------------------SP----------Code
CREATE PROCEDURE Phtotgraph_Summary_SP(photograph_classification LIKE fotografs.classificacio_fotograf)
RETURNING CHAR(100) as Photograph, INTEGER as total_Expositions, CHAR(50) as record_Exposition, INTEGER as num_photos

DEFINE photographCode varchar(8);
DEFINE photographName varchar(100);
DEFINE totalExpositions int;
DEFINE averagePhotos decimal(5,2);
DEFINE recordExposition varchar(50);
DEFINE numPhotos int;

FOREACH cursor

FOR SELECT ph.passaport,ph.nom, count(distinct ex.codi_exposicio) INTO photographCode,photographName, totalExpositions

FROM fotografs ph, exposen ex

where ph.passaport = ex.passaport

group by ph.passaport, ph.nom

Select max(ex.num_fotos) INTO numPhotos from exposen ex, Exposicions exp , fotografs ph

where ex.codi_exposicio = exp.codi_exposicio and ph.passaport = ex.passaport and ph.passaport = photographCode;

select exp.titol INTO recordExposition from exposen ex, Exposicions exp , fotografs ph

where ex.codi_exposicio = exp.codi_exposicio and ph.passaport = ex.passaport and ph.passaport = photographCode

group by exp.titol

having max(ex.num_fotos)= numPhotos;

RETURN photographName, totalExpositions,recordExposition,numPhotos WITH RESUME;

END FOREACH;
END PROCEDURE;

---End SP Code--------------
