    Lets say,

    user A queries

    select * from scott.emp;


    user B queries

    select * from scott.emp;

    But user B does not have previlages on scott.emp table.

    Since both the statements are identically same, does oracle parses the statement again
    or does it gets the info about the previleges from existing execution plan in the library cach to return the error?

    Regards

    I think that oracle would not reparse the statement, but always check the security. Because the securtiy can always change.

    The Explan-plan does not conatain security-information.
    The dictionary does.

    Hi pando;
    Sometimes it's good to not give up!
    I am a character often not asks, but
    who will not continue in asking ( hopefully the right questions )
    will not get the answer, the gift.
