Syntax options:

       RESERVING table-name
       RESERVING view-name

    Lists the tables to be locked during the transaction. Include
    all the persistent base tables your transaction will access. You
    cannot reserve created or declared temporary tables.

    If you use the RESERVING clause to specify tables, you can access
    only the tables you have reserved. However, specifying a view in
    a RESERVING clause is the same as specifying the base tables on
    which the view is based.
