Docs/数据库/oracle/oracle查询最近执行的sql.md

查看 Oracle 正在执行的 sql 语句以及发起的用户

SELECT b.sid oracleID,  
       b.username 用户名,  
       b.serial#,  
       paddr,  
       sql_text 正在执行的SQL,  
       b.machine 计算机名称
FROM v$process a, v$session b, v$sqlarea c  
WHERE a.addr = b.paddr  
   AND b.sql_hash_value = c.hash_value 

查询当前用户正在执行的SQL

select a.sid,
       a.serial#,
       a.paddr,
       a.machine,
       nvl(a.sql_id, a.prev_sql_id) sql_id,
       b.sql_text,
       b.sql_fulltext,
       b.executions,
       b.first_load_time,
       b.last_load_time,
       b.last_active_time,
       b.disk_reads,
       b.direct_writes,
       b.buffer_gets
  from v$session a, v$sql b
 where a.username = sys_context('USERENV', 'CURRENT_USER')
   and a.status = 'ACTIVE' 
   and nvl(a.sql_id, a.prev_sql_id) = b.sql_id;

查看1小时内执行的sql语句,并按照执行时间倒序排序

select s.LAST_ACTIVE_TIME,s.SQL_TEXT,s.SQL_FULLTEXT,s.FIRST_LOAD_TIME,s.LAST_LOAD_TIME,s.EXECUTIONS from v$sql s
where s.SQL_TEXT like '%DUAL%' and s.LAST_ACTIVE_TIME>sysdate-1/24
order by s.LAST_ACTIVE_TIME desc
