The name for a formal parameter. Use any valid SQL name. See the
    Oracle Rdb SQL Reference Manual for more information on user-
    supplied names.

    Formal parameter names do not have to be the same as the host
    language variables for the actual parameters to which they
    correspond. However, making the names the same is a useful
    convention for keeping track of which parameter corresponds to
    which host language variable.

    SQLCA, SQLCODE, SQLDA, SQLDA2, and SQLSTATE are special-purpose
    parameters and do not require user-supplied names (although you
    can optionally specify a parameter name with SQLDA or SQLDA2).

    There are three ways to specify a valid SQL data type for the
    formal parameter:

    o  data-type

    o  domain-name

    o  record-type
