I am trying to print values of an array one by one, but it doesn't work.
For example, if i want to print entire array at once, it does work:
CREATE OR REPLACE FUNCTION "public"."test_func" () RETURNS integer AS$body$declare i int; v_arr integer[] = '{0, 1}'; begin v_arr[1] := 5; v_arr[2] := 7; raise info 'entire array: %', v_arr; return 0;end$body$LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;But then if I try this:
CREATE OR REPLACE FUNCTION "public"."test_func_new" () RETURNS integer AS$body$declare i int; v_arr integer[] = '{0, 1}'; begin v_arr[1] := 5; v_arr[2] := 7; raise info '1st element: %', v_arr[1]; return 0;end$body$LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;
.. and it doesn't compile.
Can someone help me? Thanks!
