+# (1) If there is an AS clause, use it.
+#
+# (2) A non-trival expression (not a table column name) then the name is
+# a copy of the expression text.
+#
+# (3) If short_column_names=ON, then just the abbreviated column name without
+# the table name.
+#
+# (4) When short_column_names=OFF and full_column_names=OFF then
+# use case (2) for simple queries and case (5) for joins.
+#
+# (5) When short_column_names=OFF and full_column_names=ON then
+# use the form: TABLE.COLUMN
