Connecting V$SESSION and V$SQL

How do you connect the details of the two tables V$SESSION and V$SQL?

Using V$SESSION and V$SQL, one can get an idea of the current SQL statement a particular user is executing. In order to join these two views together, you need to link them on the SQL statement's "address" and "hash value". This can be done with the following query:

SELECT se.sid,se.username,sa.sql_text 
FROM v$session se, v$sqlarea sa 
WHERE se.sql_address=sa.address 
AND se.sql_hash_value=sa.hash_value; 
SELECT se.sid,se.username,sa.sql_text 
FROM v$session se, v$sqlarea sa 
WHERE se.prev_sql_addr=sa.address 
AND se.prev_hash_value=sa.hash_value; 

For More Information


One can also see the user's previous query by using the PREV_SQL_ADDR and PREV_HASH_VALUE columns of V$SESSION as follows:
