oracle 查询最近执行过的 SQL语句

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_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.
