Tells SQL to use all the columns in the table references referred
    to by the table name, view name, or correlation name. The name
    must be specified in the FROM clause of the select expression.

    The number of columns you specify in the select list, either by
    using wildcards or by explicitly listing value expressions, is
    the number of columns in the result table. In
