I'm trying to capture the
execution plan of my query on
PL/SQL developer as you can see below :
select * from vmi_dimcustomer t1 inner join vmi_factcustomer t2 on t1.customer_num = t2.customer_num ; Select plan_table_output from table(dbms_xplan.display_cursor(null,null,'basic'));
but I receive this note :
SQL_ID 9m7787camwh4m, child number 0 begin :id := sys.dbms_transaction.local_transaction_id; end; NOTE: cannot fetch plan for SQL_ID: 9m7787camwh4m, CHILD_NUMBER: 0 Please verify value of SQL_ID and CHILD_NUMBER; It could also be that the plan is no longer in cursor cache (check v$sql_plan)
What am I doing wrong here?
I searched here and the answer I got was to
"set serveroutput off" . Put I can not do this on PL/SQL developer.
Thanks in advance.
