I have a query contains SUBSTRING in where clause:
Select top 100 * from _Doc
where SUBSTRING(_Doc.FileNameStr, 22, 1) = '2'

This query runs on mssql but I need to use that query from sa.
I could not find anything like this in SA documentatin.
Here is what I tried so far:
q_doc =
Hello list,
I have the following models (excerpt) which represent a scoring system
(the score is the extra value, it is linked to a scorecard):
class Scoring(Base):
__tablename__ = 'scraper_scoring'
scoring_id = Column('id',Integer, primary_key=True)
extra = Column(Integer,
sqlalchemy.sql.expression.func may work for this:
from sqlalchemy.sql.expression import func
...
q_doc.filter(func.substring(model.Doc.FileNameStr, 22, 1)==search_str)
...

Thank you. it works now.
But what is the difference between
from sqlalchemy.sql.expression import func
and
from sqlalchemy import func
the second import is what I found out while experimenting with the query
and after I saw your reply, I tried your code and both works the same.
On
from sqlalchemy.sql.expression import func
from sqlalchemy import func as other_func
func == other_func
True

Hi all,
I was wondering if there is some kind of security announcements mailing
list or anything where we could be informed of security issues directly
from the horse's mouth? :) I did join the mailing list after 0.7.0 was
released so I can't tell if this particular issue was mentioned, a
Hi
My code basically does:
---
engine = create_engine()
table = Table('table', MetaData(), Column('id', Integer, primary_key=True))
table.create(bind=engine)
Session = scoped_session(sessionmaker(bind=engine))
Session.execute(text('SELECT id from table'))
---
The last statement blocks

Why would you do that?
I advise using NullPool with SQLite in the docs, if you use SQLA 0.7 the SQLite

Hi everyone,
I join an application dev team in order to solve 2 main problems with SA on
an application that use SA the wrong way.
Indeed the dev team did not understood that sessions are ad-hoc (as said
by Mike if i remember well).
So they get DetachedInstanceError sometimes on lazy loads.

Ah, so it seems I was most confused about the intended usage of the
scoped session - I was assuming that because it was designed to be
multithreaded, that would imply that the same instance would be used
for more than one request ... because an individual request is
typically handled by a single
I found a recipe on stackoverflow for turning a query instance into a
string, including parameters. I only do this for testing purposes and the
implementation is here:

However, I just upgraded to 0.7.5
