Обсуждение: Looping through Arrays
Hi
I want to be able to loop through an array. The code I have used in the past is:
FOR i IN array_lower(arrayvar,1) .. array_upper(arrayvar,1) LOOP
currentvalue:=arrayvar[1][i];
RAISE NOTICE '%', currentvalue;
END LOOP;
But now I need to loop through the whole array, not just the one element. I want to do something like:
FOR j in ....LOOP
FOR i IN array_lower(arrayvar,1) .. array_upper(arrayvar,1) LOOP
currentvalue:=arrayvar[j][i];
RAISE NOTICE '%', currentvalue;
END LOOP;
END LOOP;
How to I set the upper and lower bounds for j?

FOR j IN array_lower(arrayvar, 2)..array_upper(arrayvar, 2) LOOP :-) merlin
