oracle 查询最近执⾏过的
sql语句查询不包含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; SELECT  sql_text, last_load_time FROM v$sql WHERE last_load_time IS NOT NULL and sql_text like 'update%' ORDER BY last_load_time DESC; SELECT  sql_text, last_load_time FROM v$sql WHERE last_load_time IS NOT NULL and last_load_time like' 14-06-09%' ORDER BY last_load_time DESC;
---正在执⾏的
select a.username, a.sid,b.SQL_TEXT, b.SQL_FULLTEXT
from v$session a, v$sqlarea b
where a.sql_address = b.address
---执⾏过的
select b.SQL_TEXT,b.FIRST_LOAD_TIME,b.SQL_FULLTEXT  from v$sqlarea b where b.FIRST_LOAD_TIME between '2009-10-15/09:24:47' and
'2009-10-15/09:24:47' order by b.FIRST_LOAD_TIME  （此⽅法好处可以查看某⼀时间段执⾏过的sql，并且 SQL_FULLTEXT 包含了完整的 sql 语句）其他 select OSUSER,PROGRAM,USERNAME,SCHEMANAME,B.Cpu_Time,STATUS,B.SQL_TEXT
from V$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$sqltext  where address = sql_address    -- and machine = < you machine name >
order by address, piece  查前⼗条性能差的sql.  SELECT * FROM (select PARSING_USER_ID,EXECUTIONS,SORTS,
COMMAND_TYPE,DISK_READS,sql_text FROM v$sqlarea  order BY disk_reads DESC )where ROWNUM<10 ;  查看占io较⼤的正在运⾏的session  SELECT se.sid,se.serial#,pr.SPID,se.username,se.status,  se.terminal,se.program,se.MODULE,、se.sql_address,st.event,st.  p1text,si.physical_reads, si.block_changes FROM v$session se,v$session_wait st,  v$sess_io si,v$process pr WHERE st.sid=se.sid AND st.
sid=si.sid AND se.PADDR=pr.ADDR AND se.sid>6 AND st.  wait_time=0 AND st.event NOT LIKE '%SQL%' ORDER BY physical_reads DESC
