Thread: TAB view

    I have code in the application where it reads:

    "select xxx.NextVal from TAB;"

    Could someone give me some details on what is the reason of using TAB instead of DUAL?

    I believe, TAB is a vew for the user_tables. I would appreciate some more information on this.

    Thank You,

    TAB was a data dictionary in versions prior to and including 6. i can think of no good reason to use it in lieu of dual. in fact, it is a bad idea, since there is no way of knowing how many rows will be returned. it's very curious.
