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

#
# (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

# 2017-07-29: Interaction between column naming and query flattening.
# For years now, the query flattener has inserted AS clauses on the
# outer query that were the original SQL text of the column. This caused
# column-name shifts when the query flattener was enhanced, breaking
# legacy applications. See https://sqlite.org/src/info/41c27bc0ff1d3135
# for details.
#
# To fix this, the column naming logic was moved ahead of the query
# flattener so that column names are assigned before the query flattener
# runs.
