Hi ERROR: cannot have more than 2^32-1 commands in a transaction SQL state: 54000 Iam getting the above error when iam running my program. If iam not wrong this error ocuurs when there are too many statements executing in one single transaction. But this error is occuring in a function that iam least expecting it to occur in. The function it occurs in is as follows: BEGIN resultindex := 1; -- Go through summedprobs, find where rnum falls, set resultindex FOR i IN REVERSE (array_upper(summedprobs,1)-1)..1 LOOP IF rnum >= summedprobs[i] AND rnum <= summedprobs[i+1] THEN resultindex := i; END IF; END LOOP; RETURN (dobs[resultindex]); EXCEPTION WHEN program_limit_exceeded THEN RAISE NOTICE 'Exception in GETRES'; RETURN (dobs[resultindex]); END; Is is beacuse of the REVERSE command? or because the program is executiung many select and update statements? Catching the exception isnt helping here either.Can anyone explain me why this error occurs and what i can do to resolve it?
