1st query
SELECT DISTINCT a.test_session_id test_session_id, address,

                home_phone, institution_id_display, last_name, middle_name,
                site_id_display, state_name, student_id,
                TO_CHAR (test_session_date,
                         'yyyy-MM-dd') AS test_session_date, zip
           FROM vuestudenttestsessioninfo a, test_session_detail b
          WHERE EXISTS (
                   SELECT td.test_detail_id
                     FROM test_detail td
                    WHERE domain_map_id IS NOT NULL
                      AND b.test_detail_id = td.test_detail_id

Hi ,
Version *10.1.0.2.0*
Business rule is:
I have two scenarios 1) can use first query getting result
2) can use both queries getting result.
In second scenario i'm facing problem with regarding taking more time due to executing two queries one after one.
because i'm getting test session id's from first query executing and displaying results from both quires .Now i have thought to merge both queries as a one query.I think it's possible with in line view quires(2nd query).Pls help
And DDL part i'm using 1 view and reaming tables.here those scripts.
