In ORACLEV $ sessionTable to view the current valid session information, and can be queried through the SQL _id or SQL _address of v $ sessionV $ SQLView the SQL statements currently being executed;

If you want to view the SQL statements recently executed by the session, you can useV $ active_session_historyThe SQL _id in the table is used to view the recently executed SQL statements. The database liberary is not 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 timeFROM v$session a, v$sqlarea b, v$session_longops cWHERE a.sql_hash_value = b.hash_value(+) AND a.SID = c.SID(+)              AND a.serial# = c.serial#(+)       --AND a.sid=139

The SQL statements recently executed by Oracle:

SELECT   sql_text, last_load_timeFROM v$sqlWHERE last_load_time IS NOT NULLORDER BY last_load_time DESC

Others,

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;

Monitor the SQL statement being executed by concurrent

SELECT a.sid, a.serial#, b.sql_text  FROM v$session a, v$sqltext bWHERE a.sql_address = b.address  --AND a.sid = <...>ORDER BY b.piece

Executing

SELECT a.username, a.sid,b.SQL_TEXT, b.SQL_FULLTEXT FROM v$session a, v$sqlarea b where a.sql_address = b.address 

Executed

SELECT b.SQL_TEXT,b.FIRST_LOAD_TIME,b.SQL_FULLTEXTFROM v$sqlarea bWHERE b.FIRST_LOAD_TIME between '2009-10-15/09:24:47' and       '2009-10-15/09:24:47' order by b.FIRST_LOAD_TIME 

(This method allows you to view the SQL statements executed in a certain period of time, andSQL _FULLTEXTContains the completeSQLStatement)

Others

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
