Problem (solved) with toSession:OpenCursor query
The order of the selected columns is important, and currently (version 3.2) wrong. As a consequence, the right hand side of the Open Cursors (sql text, explain plan, ...) remains empty or causes errors. Easily solved by using the following query:
select SQL_Text SQL
, p.child_number as chld
, c.SQL_ID as sqlid
, CURSOR_TYPE
, LAST_SQL_ACTIVE_TIME
, SQL_EXEC_ID
from v$open_cursor c
join v$sql_plan p
on c.ADDRESS = p.ADDRESS
and c.HASH_VALUE = p.HASH_VALUE
and c.sql_id = p.sql_id
and p.id = 0
where sid = :f1<char[101]>
If you prefer these columns remain hidden, change the aliases. as chld => as " child_number" as sqlid => as " sql_id" (an alias starting with a space hides the column)
