Subj:   Re: Quesion on Explain plan on "Create a new table"
 
From:   David Wellman



Hi Akleema,

If I've understood what you're saying then I believe that you're correct.

Anytime that the optimiser/dbms needs to check for the presence or absence of an object it uses an abort test. So when creating a table (for instance) there are two abort tests: one is to check that the database DOES exist, the second is to check that the table DOESN'T exist in the database.


Cheers,

Dave
