# Rules (applied in order):
|
|
#
|
|
# (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
|
|
#
|
|
|
|
|
|
# Verify the default settings for short_column_name and full_column_name
