获取存储过程中执行的每个语句的 SQL ID

Question

我有以下存储过程：

create or replace procedure insert_employee_to_dept (f_name IN varchar2, l_name IN varchar2, dept IN varchar2, tier IN char)
is
    dept_count number;
    t1_count number;
begin
    INSERT INTO employees (id, first_name, last_name, department, tier)
        VALUES (employee_sequence.NEXTVAL, 
                f_name,
                l_name, 
                dept,
                tier);
    select count(*) into dept_count from employees where department = dept;
    update dept_info set emp_count = dept_count where id = dept;
    select count(*) into t1_count from employees where tier = 1;
    update company set tier_one_count = t1_count where name = 'MyCompany';
end;

我使用下面的语句启用 SQL ID 反馈

set feedback on sql_id;

最后我运行我的存储过程是这样的：

call insert_employee_to_dept('John', 'Doe', 'Finance', '5')

上述命令的输出包含 PL/SQL 块的 SQL id 但此块没有可以使用 DBMS_XPLAN.DISPLAY_CURSOR[=16= 查询的执行块]

有没有办法获取调用存储过程时执行的所有 SQL ID？

如果你这样做是为了测试目的，你可以使用 dbms_application_info 设置 module 和 action，然后使用它们从 v$[= 到 select 25=]$sqlarea/v$active_session_history/etc:

SQL> declare
  2     n number;
  3  begin
  4     dbms_application_info.set_module('test_module','test_action');
  5     select/*+test1*/ count(*) into n from dual;
  6     select/*+test2*/ count(*) into n from dual;
  7     dbms_application_info.set_module('','');
  8  end;
  9  /

PL/SQL procedure successfully completed.

SQL> select sql_id,substr(sql_text,1,50) sqltext50
  2  from v$sqlarea
  3  where module='test_module'
  4    and action='test_action';

SQL_ID        SQLTEXT50
------------- ------------------------------------
bavxnddfrxju6 SELECT/*+test2*/ COUNT(*) FROM DUAL
7d8853usybzdg SELECT/*+test1*/ COUNT(*) FROM DUAL

顺便说一句，您也可以将 module/action/client_id 用于 dbms_monitor： Performing Application Tracing DBMS_MONITOR

或者有时您甚至可以使用 v$open_cursor（取决于许多因素，例如 open_cursor 参数等）：

SQL> declare
  2     n number;
  3  begin
  4     dbms_application_info.set_module('test_module','test_action');
  5     select/*+test10*/ count(*) into n from dual;
  6     select/*+test11*/ count(*) into n from dual;
  7     dbms_application_info.set_module('','');
  8  end;
  9  /

PL/SQL procedure successfully completed.

SQL> select sql_id,substr(sql_text,1,50) sqltext50
  2  from v$open_cursor
  3  where sid=userenv('sid')
  4  and user_name=user
  5  and last_sql_active_time is not null
  6  order by last_sql_active_time desc
  7  fetch first 5 rows only;

您可以使用all_statements系统视图获取在PL/SQL单元中执行的所有语句及其SQL_ID。

create table t (
  id int,
  val int
)
/

create or replace procedure test_proc(
  p_id in int
)
as
begin
  insert into t(id, val) values(p_id, 100);
  update t set val = 10;
  delete from t where id = p_id;
end;
/

begin
  test_proc(1);
end;
/

select
  owner
  , object_type
  , object_name
  , type
  , line
  , sql_id
  , text
from all_statements
/

OWNER	OBJECT_TYPE	OBJECT_NAME	TYPE	LINE	SQL_ID	TEXT
DEMO	PROCEDURE	TEST_PROC	DELETE	8	85cd3d95cya5x	DELETE FROM T WHERE ID = :B1
DEMO	PROCEDURE	TEST_PROC	UPDATE	7	d6au94gzv1ydh	UPDATE T SET VAL = 10
DEMO	PROCEDURE	TEST_PROC	INSERT	6	bm74chwppp8w4	INSERT INTO T(ID, VAL) VALUES(:B1 , 100)
