我在Oracle中有一个用于获取和显示数据的存储过程。但我想在其中实现另外一个功能。

我想要的是,我想要抛出一个异常,而这个异常我想要登录到一个Oracle表中

示例存储过程

CREATE OR REPLACE PROCEDURE GET_FCA_GISDATA(
                                            P_GRPNAME    IN NVARCHAR2, 
                                            TBLDATA_APP OUT SYS_REFCURSOR 
                                           ) AS
BEGIN
    OPEN TBLDATA_APP FOR

      SELECT IP.ID,
             IP.SAP_ID,
             IP.ID_OD_COUNTCHANGE,
             IP.ID_OD_CHANGEDDATE,
             IP.RRH_COUNTCHANGE,
             IP.RRH_CHANGEDDATE,
             IP.TENANCY_COUNTCHANGE,
             IP.TENANCY_CHANGEDDATE,
             ST.STATUS,
             IP.RFE1_DATE_BAND,
             IP.RFS_DATE_BAND,
             IP.CREATED_BY
        FROM TBL_IPCOLO_MAST_INFO IP
        LEFT JOIN TBL_IPCOLO_STATUS ST
          ON IP.FCA_STATUS = ST.ID
       WHERE UMS_GRP_TO_NAME = P_GRPNAME
         AND ST.ISACTIVE = 1
       ORDER BY 12 DESC;

    COMMIT;

  EXCEPTION
    WHEN OTHERS THEN
      ROLLBACK;  
END GET_FCA_GISDATA;

请建议如何抛出异常。

如何提出您自己的异常?这样地:

SQL> set serveroutput on
SQL> create or replace procedure p_test is
  2    my_ex exception;
  3  begin
  4    raise my_ex;
  5  exception
  6    when my_ex then
  7      dbms_output.put_line('My exception');
  8  end;
  9  /

Procedure created.

SQL> exec p_test
My exception

PL/SQL procedure successfully completed.

SQL>

展示它 在屏幕上,您可以将其存储到某个表中。

Select count(1)
  Into v_locked
  From all_objects o
  Join v$locked_object l on o.object_id = l.object_id
  Join v$session s on l.session_id = s.sid
  Join v$session_wait w on s.sid = w.sid
 Where o.object_name = 'TBL_IPCOLO_MAST_INFO'
   and s.status = 'ACTIVE'
   and lower(w.event) like '%enq%contention%' --> "enq: TX - row lock contention"

如果 v_locked zero 然后,相关表有一个 row lock contention v_locked > 0 .
