I am just trying to see what is happening in background , when i fire simple sql. Using F10 to see that explain plan.
SQL query is showing results.
My database Description is as below.
Oracle Database 11g Enterprise Edition Release 22.214.171.124.0 - 64bit Production
PL/SQL Release 126.96.36.199.0 - Production

TNS for Linux: Version 184.108.40.206.0 - Production
NLSRTL Version 220.127.116.11.0 - Production
This means one of the statements that sqldeveloper sent to the RDBMS failed. Check the statements log which one.
