Question

如何查看oracle某用户近期执行的SQL

Answer 1

　　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;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_FULLTEXTfrom 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_FULLTEXTfrom v$sqlarea b
　　where b.FIRST_LOAD_TIME between '2009-10-15/09:24:47' and'2009-10-15/09:24:47' order by b.FIRST_LOAD_TIME（此方法好处可以查看某一时间段执行过的sql，并且 SQL_FULLTEXT 包含了完整的 sql 语句）其他
　　select OSUSER,PROGRAM,USERNAME,SCHEMANAME,B.Cpu_Time,STATUS,B.SQL_TEXTfrom V$SESSION A LEFT JOIN V$SQL B ON A.SQL_ADDRESS=B.ADDRESS AND A.SQL_HASH_VALUE=B.HASH_VALUE order by b.cpu_time descselect address, sql_text, piece
　　from v$session, v$sqltext
　　where address = sql_address
　　-- and machine = < you machine name >
　　order by address, piece
　　查找前十条性能差的sql.
　　SELECT * FROM (select PARSING_USER_ID,EXECUTIONS,SORTS,COMMAND_TYPE,DISK_READS,sql_text FROM v$sqlareaorder 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

Answer 2

不能查看近期执行的sql，当前执行的可以查看。
