Hi,
I am trying to compress some data down into a single row (making it an
array). I believe I am close, but I still keep getting an error: "ERROR:
query has no destination for result data"
Does anyone have an idea what is going wrong? Thanks.
CREATE or REPLACE FUNCTION getVSS(f_pvid integer, f_time timestamp, OUT
o_port integer[], OUT o_conf double precision[], OUT d_port integer[], OUT
d_conf double precision[]) RETURNS setof record as $$ DECLARE vssview RECORD;
BEGIN o_port = ARRAY[0]; o_conf = ARRAY[0]; d_port = ARRAY[0]; d_conf = ARRAY[0]; FOR vssview IN select
vss_orig.portid,vss_orig.confidence from vss,
vss_orig where vss.vssmsg = vss_orig.vssmsg AND pvid = f_pvid and f_time
between starttime and endtime LOOP select array_append(o_port, vssview.portid); select array_append(o_conf,
vssview.confidence);END LOOP; FOR vssview IN select vss_dest.portid, vss_dest.confidence from vss,
vss_dest where vss.vssmsg = vss_dest.vssmsg AND pvid = f_pvid and f_time
between starttime and endtime LOOP select array_append(d_port, vssview.portid); select array_append(d_conf,
vssview.confidence);END LOOP;
END;
$$ LANGUAGE plpgsql;
