|
|
#
|
|
# (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

# 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.
