b) Otherwise, the <select list> “*” is equivalent to a <value expression>
sequence in which each <value expression> is a column reference that
references a column of T and each column of T is referenced exactly once. The
columns are referenced in the ascending sequence of their ordinal position
within T.

b) The column descriptors of every column of T, according to the Syntax Rules
and General Rules of Subclause 11.4, “<column definition>”, applied to the
<column definition>s contained in TEL, in the order in which they were
specified.
