I would agree that the approach taken by pg_largeobject is a useful
approach in that you can read just

After upgrading sqlite to the most recent version (3.3.10), my problem
went away and everything works as expected.
Thanks for the help, and sorry for the noise.

without seeing a full example, its looking like a mysql bug. SA's
datetime implementation for MySQL doesnt do any conversion from return
value since MySQLDB handles that task. whereas the sqlite dialect in
SA *does* do conversion since sqlite doesnt handle that.

Hi All,
Trying to implement full text search with PostgreSQL and tsearch2,
being a beginner, I am facing some basic hurdles:
1. How to declare a table in SA, I mean, what SA datatype should
tsvector correspond to?
2. Can the index be defined using SA, or we need to do it in the
backend?
3. Can

This means that if someone is querying the table in the middle of the
transaction it'll get wrong results.
(I'm not a DB expert, this might be total nonsense)
no, it just means that queries run in the same uncommitted

just a note, when you use SQLite, by default you get the same
connection every time within a single thread, since its using
SingletonThreadPool. read the docs for options on how to change this.

i dont know much about tsvector, but as to the various can the
trigger/index be defined in SA, no, you have to use literal postgres
commands to do that (which you can of course issue from SA as textual
statements). since they are pg-specific anyway, theres not much
advantage to SA supporting

I would like to access the underlying psycopg2 connection to get at a DBAPI2

moving large amounts of data to/from the database. I can't seem to find a

Consider the following model:

def __init__(self, text):
self.text = text
CommentTable=Table('Comment', metadata,

Column('text', Unicode(512)),

the ImageComment mapper is superfluous to the example. you should
generally not map a class to a table, then also use that table as the
secondary join in another mapping; since changes to one wont get
reflected in the other. If you want to use ImageComment, then you need
to use the association
ticket 427 is fixed in rev 2216. so using the trunk or 0.3.4 when i
get around to releasing, this is the program:

secondary=ImageCommentTable, lazy=False, cascade=all, delete-orphan)}
