Explicitly declares a table or view definition in a program. For
    tables named in a DECLARE TABLE statement, SQL does not check the
    schema to compare the definition with the explicit declaration.

    An explicit table declaration is useful to:

    o  Document the definition in the source code of the program

    o  Allow references to tables that do not exist when SQL
       precompiles the program, including:

       -  Tables created in other modules of the program

       -  Tables created dynamically

    o  Improve precompiler performance because SQL does not need to
       attach to the schema to retrieve the table definition

    o  Make it easier to check that the declaration correctly
       corresponds to a host structure the program uses to hold
       values from or for the table

    o  Declare only a subset of columns contained in the schema
       definition of the table if the program needs to use only some
       of the columns
