It seems what when using .first() with from_statement() I get a
traceback with 0.5rc4 when no rows are found (works when a row is fount):
using 0.4.8 I get:
/usr
0.4.8
with 0.5rc4 I get:
/users/dgardner/dev
0.5.0rc4
Traceback (most recent call last):
File "assetdb_test.py", line 38, in <module>
session.query(Note).from_statement(qry%(uid,name,updated)).first()
File
"/users/dgardner/dev/lib/python2.5/site-packages/SQLAlchemy-0.5.0rc4-py2.5.egg/sqlalchemy/orm/query.py",
line 1025, in first
return list(self)[0]
IndexError: list index out of range
