--oracle 查询最近执行过的 SQL语句
select sql_text,last_load_time from v$sql order by last_load_time desc;

SELECT sql_text, last_load_time FROM v$sql WHERE last_load_time IS NOT NULL and sql_text like 'select%' ORDER BY last_load_time DESC;

--正在执行的
select a.username, a.sid,b.SQL_TEXT, b.SQL_FULLTEXT

---执行过的
select b.SQL_TEXT,b.FIRST_LOAD_TIME,b.SQL_FULLTEXT

       '2021-08-20/10:30:00' order by b.FIRST_LOAD_TIME 
/*(此方法好处可以查看某一时间段执行过的sql,并且 SQL_FULLTEXT 包含了完整的 sql 语句)*/

--其他
select OSUSER,PROGRAM,USERNAME,SCHEMANAME,B.Cpu_Time,STATUS,B.SQL_TEXT 
from V$SESSION A LEFT JOIN V$SQL B ON A.SQL_ADDRESS=B.ADDRESS AND A.SQL_HASH_VALUE=B.HASH_VALUE order by b.cpu_time desc 


select address, sql_text, piece 
  from v$session, v$sqltext 
where address = sql_address 
  -- and machine = < you machine name > 
order by address, piece 


--查询Oracle正在执行的sql语句及执行该语句的用户
SELECT B.SID      ORACLEID,
       B.USERNAME 登录ORACLE用户名,
       B.SERIAL#,
       SPID       操作系统ID,

       SQL_TEXT   正在执行的SQL,
       B.MACHINE  计算机名
  FROM V$PROCESS A, V$SESSION B, V$SQLAREA C

--查看正在执行sql的发起者的发放程序   
SELECT OSUSER     电脑登录身份,
       PROGRAM    发起请求的程序,
       USERNAME   登录系统的用户名,

--查找前十条性能差的sql. 

SELECT * FROM (select PARSING_USER_ID,EXECUTIONS,SORTS,
