Oracle根据SQL_ID批量收集真实执行计划

   日常检查AWR报告会发现一些慢的SQL语句，需要做性能调优，这个时候需要把内存中的真实执行计划和绑定变量的值弄出来。下面就是通用脚本：
sqlplus TEST/[email protected]
set serveroutput on size 100000
spool d:/result.txt
set pagesize 200
set linesize 800
declare
cursor c_cursor is select hash_value, child_number from gv$sql s
  where s.SQL_ID in('c6yba8xcph0cb') order by hash_value;
c_row c_cursor%rowtype;
TYPE t_arry_plan IS VARRAY(1000) OF VARCHAR2(200);  
array_plan t_arry_plan;
begin
  DBMS_OUTPUT.ENABLE(buffer_size=>null);
  for c_row in c_cursor loop
      select plan_table_output bulk collect into array_plan from
            table(dbms_xplan.display_cursor(c_row.hash_value, c_row.child_number, 'advanced'));
      FOR i IN array_plan.FIRST .. array_plan.LAST LOOP  
        DBMS_OUTPUT.PUT_LINE(array_plan(i));  
    END LOOP;  
    DBMS_OUTPUT.PUT_LINE('**************************************************************************'); 
    DBMS_OUTPUT.PUT_LINE(chr(10)||chr(10)||chr(10));     
  end loop;
end;
/
spool off;


出来的结果是：
SQL> declare
  2  cursor c_cursor is select hash_value, child_number from v$sql s
  3    where s.SQL_ID in('fbbm59qban13m','5n0t3uxw307bd') order by hash_value;
  4  c_row c_cursor%rowtype;
  5  TYPE t_arry_plan IS VARRAY(1000) OF VARCHAR2(200);
  6  array_plan t_arry_plan;
  7  begin
  8    DBMS_OUTPUT.ENABLE(buffer_size=>null);
  9    for c_row in c_cursor loop
 10        select plan_table_output bulk collect into array_plan from
 11              table(dbms_xplan.display_cursor(c_row.hash_value, c_row.child_number, 'advanced'));
 12        FOR i IN array_plan.FIRST .. array_plan.LAST LOOP
 13          DBMS_OUTPUT.PUT_LINE(array_plan(i));
 14      END LOOP;
 15      DBMS_OUTPUT.PUT_LINE('*****************************************************');
 16      DBMS_OUTPUT.PUT_LINE(chr(10)||chr(10)||chr(10));
 17    end loop;
 18  end;
