Query running for too long

Question

Hi All,
Can someone pls help me in finding how long will it take to execute the below query.
I have a query that is taking too long to execute.
SELECT   CPU_TIME/1000000/60 CPUTIME, ELAPSED_TIME/1000000/60 ELAPSEDTIME, PROGRAM_LINE#, OPTIMIZER_COST,
USER_IO_WAIT_TIME/1000000/60 IOWAITTIME,  DISK_READS, DIRECT_WRITES, BUFFER_GETS, to_char(Q.SQL_FULLTEXT), OPTIMIZER_MODE,  SHARABLE_MEM, PERSISTENT_MEM, RUNTIME_MEM, SORTS, FETCHES, EXECUTIONS, END_OF_FETCH_COUNT, USERS_EXECUTING, LOADS,
FIRST_LOAD_TIME,  INVALIDATIONS, PARSE_CALLS, APPLICATION_WAIT_TIME, CONCURRENCY_WAIT_TIME, CLUSTER_WAIT_TIME,
PLSQL_EXEC_TIME, JAVA_EXEC_TIME, ROWS_PROCESSED, COMMAND_TYPE, PARSING_USER_ID, PARSING_SCHEMA_ID, PARSING_SCHEMA_NAME, OBJECT_STATUS
     FROM     v$session S, v$sqlarea Q
     WHERE    S.SQL_ADDRESS = Q.ADDRESS
     AND      s.username = 'SCHEMA_NAME'
     AND       s.osuser = 'OSUSER_NAME';I can see CPU_TIME increasing. Is there any way that I can find how lmuch more time will it take for the query to execute.
The query creates a table that has a sub query and inner query.

There is a dynamic performance view v$session_longops that is populated for many long running operations in Oracle. The primary criterion for any operation to appear in v$session_longops is to run more than 6 seconds. Although this isn’t the only criterion as well as not all operations that take more than 6 seconds are shown in this view. For example one can find hash joins in v$session_longops, but you won’t find there nested loop joins even if they are longer than 6 seconds and are joining very big data sets.
