# The following behaviors (duplicate column names on an INSERT or UPDATE)
# are undocumented.  <<---  Not so.  There is a long-standing requirement
# in lang_update.in to say that when the columns to be updated appear more
# than once in an UPDATE statement that only the rightmost expression is used.
# See e_update-1.6.* for the tests.  This is unfortunate, since omitting
# that requirement would greatly simplify the fix to the problem identified
# by forum post https://sqlite.org/forum/info/16ca0e9f32c38567
#
# These tests are added to ensure that historical behavior
# does not change accidentally.
#
# For duplication columns on an INSERT, the first value is used.
# For duplication columns on an UPDATE, the last value is used.
