Oracle PLSQL 在每批完成后打印批量批输出

如何解决Oracle PLSQL 在每批完成后打印批量批输出

我有以下 plsql 批量脚本，可在整个更新完成后打印每个批次大小和批次完成时间的输出。

set timing on echo on verify on Feedback on
set serveroutput on
whenever sqlerror exit failure rollback

declare 
    type update_id is table of tbl_source%rowtype;
    tab      update_id := update_id();
    start_time   number;
    end_time     number;
    c_limit      int;  -- bulk collect limit
    cursor load_cur is
    select * from tbl_source;

begin
    open load_cur;
    start_time := dbms_utility.get_time;
    loop
        fetch load_cur
             bulk collect into tab limit &c_limit;
        begin
            forall i in tab.first..tab.last
                
                update tbl_target
                   set value = tab(i).name
                 where id = tab(i).id
                ;

                dbms_output.put_line('Bulk    (' || tab.count || ' rows): ' || (dbms_utility.get_time - start_time)/100 || 'seconds');

            exception
            when others then
                dbms_output.put_line('Updated '|| sql%rowcount                                     || ' rows.');
                dbms_output.put_line(sqlerrm);
            commit;

        end;

        exit when load_cur%notfound;
    end loop;

    end_time := dbms_utility.get_time;
    dbms_output.put_line('Bulk Update Time taken: ' || (end_time - start_time)/100 || 'seconds');
    close load_cur;
end;

但是我需要在第一批完成后立即打印批次大小和完成时间，以此类推以用于下一批。所以我会知道有多少批次已经完成，有多少批次待处理。
