I am trudging through the unit tests for the Sybase backend and found
an interesting one in test_nonreflected_fk_raises in engine/
reflection.py. A couple of the drivers look like they skip over the
column if it is not contained within table.c but go ahead and create
the primary_key in any case! This seems a bit odd to me. Is this the
intended behavior?

# I think we have to raise some kind of exception here if
# we try and reflect on an index when the column is
# omitted from include_columns?
if include_columns and column_name not in include_columns:
raise exc.NoReferencedColumnError(
"Could not create PrimaryKey/Index '%s' on table
'%s': "
"table '%s' has column named '%s' but it is not
present in include_columns:%s" % (
index_name, table.name, table.name,
column_name,','.join(include_columns)))
if r.status & 0x800 == 0x800:
table.primary_key.add(table.c[row[0]])
if not index_name in PK.keys():
PK[index_name] = PrimaryKeyConstraint(name =
index_name)
PK[index_name].add(table.c
[column_name])
else:
if not index_name in INDEXES.keys():
INDEXES[index_name] = Index(index_name, unique=
(r.status & 0x2 == 0x2))
INDEXES[index_name].append_column(table.c[column_name])
