查询结果显示，sql_id为 fm0738ywgbyxk 出现很多（异常sql_id）

---12个进程
SELECT sid,serial#,sql_id from v$session where sql_id in ( ‘fm0738ywgbyxk‘ ); SELECT count(*) from v$session where sql_id in ( ‘fm0738ywgbyxk‘ );
---随机抽一条，查看一下具体是执行的啥内容
select sql_text from v$sqlarea a,v$session b where a.SQL_ID=b.PREV_SQL_ID and b.SID=‘291‘;
select c.SCHOOL_ID WAREHOUSE_ID, count( ARCHIVE_ID) SIGN,c.BUSINESS_TYPE from TB_CONTRACT c,FES_STAFF_ARCHIVE st where c.state!=2000 and st.id=c.ARCHIVE_ID and c.PAY_DATE between to_date(‘2020-02-01 00:00:00‘,‘yyyy-MM-dd HH24:MI:SS‘) and to_date(‘2020-04-27 23:59:59‘,‘yyyy-MM-dd HH24:MI:SS‘) and c.BUSINESS_TYPE in (17,21) group by c.SCHOOL_ID ,c.BUSINESS_TYPE
--- 生成kill语句
SELECT ‘alter system kill session ‘‘‘ || SID || ‘,‘ || serial# || ‘‘‘;‘ FROM v$session WHERE sql_id IN (‘fm0738ywgbyxk‘);
--- 执行生成的kill语句，如下：
alter system kill session ‘291,42431‘; alter system kill session ‘483,24520‘; alter system kill session ‘667,23176‘; alter system kill session ‘768,57609‘; alter system kill session ‘861,65267‘; alter system kill session ‘1243,1739‘; alter system kill session ‘1335,44615‘; alter system kill session ‘1522,31640‘; alter system kill session ‘1622,30425‘; alter system kill session ‘1716,7696‘; alter system kill session ‘1808,44494‘; alter system kill session ‘2096,58865‘;
