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 #
39 # Verify the default settings for short_column_name and full_column_name
