 21# Rules (applied in order):
 22#
 23# (1) If there is an AS clause, use it.
 24#
 25# (2) A non-trival expression (not a table column name) then the name is
 26#     a copy of the expression text.
 27#
 28# (3) If short_column_names=ON, then just the abbreviated column name without
 29#     the table name.
 30#
 31# (4) When short_column_names=OFF and full_column_names=OFF then
 32#     use case (2) for simple queries and case (5) for joins.
 33#
 34# (5) When short_column_names=OFF and full_column_names=ON then
 35#     use the form: TABLE.COLUMN
 36#
