25: # (2) A non-trival expression (not a table column name) then the name is

27: #
28: # (3) If short_column_names=ON, then just the abbreviated column name without
29: # the table name.

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.
