Firebird treats the word 'count' as a keyword, so
mapper / testcount does this:
mapper(User, users)
q = create_session().query(User)
self.assert_(q.count()==3)
self.assert_(q.count(users.c.user_id.in_(8,9))==2)
self.assert_(q.count_by(user_name='fred')==1)
which produces:
SQL error code = -104\n Token unknown - line 1, column 20\n count')
'SELECT count(?) AS count \nFROM users' [1]
Is it safe to change sql.py/ FromClause and TableClause count() to use a
different label than "count"?
Since in this case, the count method is returning it's value, the actual label
used
doesn't seem to matter.
Also, Firebird only allows
count(*)
or
count(column_ref)
So I am not sure how
func.count(1)
is supposed to be handled.
Where in the engine do I override the handling of count? I couldn't trace much
beyond sql.FunctionGenerator.
Somehow the engine needs a crack at changing count..
