ORACLE中可以通过v$session表查看当前有效的session信息，并且可以通过v$session的sql_id或sql_address通过关联查询v$sql查看当前正在执行的sql语句；

如果想查看session近期执行的sql语句,可以通过v$active_session_history表中的sql_id查看近期历史执行的sql语句,要求数据库的liberary没有被fresh。

SELECT b.sql_text, --content of SQL a.machine, --which machine run this code a.username, a.module, -- the method to run this SQL c.sofar / totalwork * 100, --conplete percent c.elapsed_seconds, --run time c.time_remaining --remain to run time FROM v$session a, v$sqlarea b, v$session_longops c WHERE a.sql_hash_value = b.hash_value(+) AND a.SID = c.SID(+) AND a.serial# = c.serial#(+) --AND a.sid=139

Oracle 最近执行过的sql语句:

SELECT sql_text, last_load_time FROM v$sql WHERE last_load_time IS NOT NULL ORDER BY last_load_time DESC 其它，

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; 监控concurrent 正在执行的sql SELECT a.sid, a.serial#, b.sql_text FROM v$session a, v$sqltext b WHERE a.sql_address = b.address --AND a.sid = ORDER BY b.piece 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$sqlarea ORDER BY disk_reads DESC )WHERE ROWNUM6 AND st. wait_time=0 AND st.event NOT LIKE '%SQL%' ORDER BY physical_reads DESC
