Explain plan question

Hi there, I have been away from Oracle for a while and so I have forgotten some things. I remember that there was a command that would show the query execution plan for each query. It was set for a user and after it was set, every query by the user would show the execution plan. Could you kindly tell me what that command is? Thank you.

If you have Plan table created in the Schema,

Use This

Set Autot On

This will help

Thanks..

set autotrace on;

Thanks you very much guys
