Sorry I am new to this forumThen I suggest you to start reading: SQL and PL/SQL FAQ
Particularly post CREATE TABLE and INSERT statements, explain the logic and post your expected output.
When you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
It's also considered a good practice to mark questions as answered when the answers are satisfying your question or provide additional details.
