Oracle查看执⾏过的SQL

Oracle查看执⾏过的SQL
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 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 以sysdba登录
sqlplus / as sysdba;
执⾏如下sql查看最近3天执⾏的delete和truncate操作
SELECT c.username,
a.program,
b.sql_text,
b.command_type,
a.sample_time
FROM dba_hist_active_sess_history a
JOIN dba_hist_sqltext b
ON a.sql_id = b.sql_id
JOIN dba_users c
ON a.user_id = c.user_id
WHERE a.sample_time BETWEEN SYSDATE - 3 AND SYSDATE
AND b.command_type IN (7, 85)
ORDER BY a.sample_time DESC;
搜出结果还算有⽤，虽然都是业务删除，记录下
--查询Oracle正在执⾏的sql语句及执⾏该语句的⽤户
SELECT b.sid oracleID,
b.username 登录Oracle⽤户名,
b.serial#,
spid 操作系统ID,
paddr,
sql_text 正在执⾏的SQL,
b.machine 计算机名
FROM v$process a, v$session b, v$sqlarea c
WHERE a.addr = b.paddr
AND b.sql_hash_value = c.hash_value
--查看正在执⾏sql的发起者的发放程序
SELECT OSUSER 电脑登录⾝份,
PROGRAM 发起请求的程序,
USERNAME 登录系统的⽤户名,
SCHEMANAME,
B.Cpu_Time 花费cpu的时间,
STATUS,
B.SQL_TEXT 执⾏的sql
FROM V$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
--查出oracle当前的被锁对象
