Hello,
Please help me in accessing multi-dimentional array in postgresql
PL/PGSQL.
for i in array_lower(product_list, 1) .. array_upper(product_list, 1)
LOOP
product_list[i][0];
END LOOP;
Is the above code right?
Or is there any other way to access, i am getting null for
product_list[i][0];
By default, PostgreSQL uses 1-based arrays (i.e. no [0] slot), so maybe
that's your problem.
I just tried it myself: doing this -
select ('{a, b, c}'::text[])[0]
- gives me NULL.
