Checking V$FIXED_VIEW_DEFINITION, you can see that V$SQLAREA is based off of
x$kglcursor_child_sqlid, V$SQL is off x$kglcursor_child, and V$SQLTEXT is off
x$kglna. I may be way off on this, but I believe pure DDL is not a cursor,
which is why it won't be found in X$ cursor tables. Check with a CTAS vs. a
plain CREATE TABLE ... (field ...). CTAS uses a cursor and would be found in
all the X$ sql tables. A plan CREATE TABLE won't.
Again, I may be way off on the reason why, but hopefully the above helps
explain a little of what you're seeing.

Subject: What are the differences of v$sqltext, v$sqlarea, v$sql
Hi Guys,
Weird scenario, when I'm looking for TRUNCATE statement, I can see it in
V$SQLTEXT .... but I can't see it in V$SQLAREA and V$SQL
select * from v$sqltext where upper(sql_text) like '%TRUNCATE%TEST3%'; --
returns the truncate statement
select * from v$sqlarea
where sql_id = 'dfwz4grz83d6a'
where upper(sql_text) like '%TRUNCATE%'; -- no rows
select * from v$sql
where sql_id = 'dfwz4grz83d6a'
where upper(sql_text) like '%TRUNCATE%'; -- no rows
So to have a more readable ASH... I joined it with SQL_TEXT so I can clearly
see the TRUNCATE statement on the samples...
set lines 3000
select substr(sa.sql_text,1,500) txt, a.sample_id, a.sample_time, a.session_id,
a.session_serial#, a.user_id, a.sql_id,
a.sql_child_number, a.sql_plan_hash_value,
a.sql_opcode, a.plsql_object_id, a.service_hash, a.session_type,
a.session_state, a.qc_session_id, a.blocking_session,
a.blocking_session_status, a.blocking_session_serial#, a.event,
a.event_id,
a.seq#, a.p1, a.p2, a.p3, a.wait_class,
a.wait_time, a.time_waited, a.program, a.module, a.action, a.client_id
from gv$active_session_history a, gv$sqltext sa
where a.sql_id = sa.sql_id
and session_id = 126
So my question is, what are the differences of v$sqltext, v$sqlarea, v$sql?
Any ideas? :)
