Oracle获取最近执行的SQL语句

            select  last_load_time, sql_text from v$sql 
where module notin (‘jsenv.exe‘,‘w3wp.exe‘,‘SQL Developer‘) 
--and sql_text like ‘%"Extent1"."ENCOUNTERID"%‘ orderby last_load_time desc;

select sql_text,last_load_time from v$sql orderby last_load_time desc;

SELECT   sql_text, last_load_time FROM v$sql WHERE last_load_time ISNOTNULLand (sql_text like‘select%‘or sql_text like‘SELECT%‘) ORDERBY last_load_time DESC;

SELECT   sql_text, last_load_time FROM v$sql WHERE last_load_time ISNOTNULLand sql_text like‘update%‘ORDERBY last_load_time DESC;

SELECT   sql_text, last_load_time FROM v$sql WHERE last_load_time ISNOTNULLand last_load_time like‘ 2017-6-9%‘ORDERBY last_load_time DESC;

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‘2017-6-9/13:24:47‘and‘2017-6-9/15:24:47‘orderby 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）
