plsql - Invalid cursor exception in 2nd iteration -


i getting invalid cursor exception while iterating 2nd time.

load_table_ref_cursor(v_tariff_table_rows); -- v_tariff_table_rows sys_refcursor.

when doing iteration below.

load_table_ref_cursor(v_tariff_table_rows);     loop         fetch v_tariff_table_rows tak_row;         exit when v_tariff_table_rows%notfound;       end loop;

the control inside loop going 1st time fine , throwing exception invalid cursor @ fetch statement 2nd time.

could tell whats wrong 2nd iteration.

invalid cursor error produced when; fetch cursor before opening cursor. fetch cursor after closing cursor. close cursor before opening cursor.

load_table_ref_cursor(v_tariff_table_rows);  open v_tariff_table_rows;      -- use v_tariff_table_rows  close v_tariff_table_rows;
