[sqlalchemy] Re: Threading
It seems the problem is something else. A while back I ran into issues where on Windows and MS SQL, my data was not not being inserted into my tables. For some reason, by adding metadata.createall() right before I return my Session in my getsession() function, data started inserting again. This worked for both Windows, Mac, and Linux. Now switching my app to use the multiprocessor threadin library, that metadata.createall() throws all kinds of errors on Mac/Linux, if I remove it everything runs great except on Windows where data does not insert again. Any ideas where I should start looking?

[sqlalchemy] cascades and mappers
To get foreign keys in my python app I am doing the following: ForeignKeyConstraint(['USERID'], ['USERS.USERID'], ondelete=CASCADE) and my mappers are nothing more than mapper(class, table). Is there anything wrong with not defining the relation in the mapper as well?

With r5930 I've moved all savepoint logic into savepoint oriented routines so it will not step on non-savepoint based code. Savepoint support is still very experimental in mssql. I'd appreciate as many eyes as possible on this changeset, as well as testing it out against problem code to see if this corrects our issues. At this point I'm pretty satisfied with the implementation based on the tests. I only have one failing test and after a couple of hours of comparing profile traces I'm still unable to understand why it's failing. The trace results are exactly the same. All other savepoint related tests are passing just fine. If this changeset still creates a problem (it shouldn't) let me know and we'll just revert all savepoint functionality. As of yet I still have not seen an isolated test case that illustrates the failures, so that makes me a bit uneasy in making code changes. So, if someone could produce an isolated test case that fails on the previous version of trunk that would still be very helpful to understand where the problem is. Thanks for everyone's help.

[sqlalchemy] Re: pyodbc issues
I tried reinstalled pyodbc many times. Still creates the tables just fine but no inserts. Am I doing this correctly: db.py contains: engine create scoped session table definitions mappers meta creates/delete each object has its own .py for example servers.py but contains no column information about that table. then I run a file which makes a server object, adds to session, flush...

[sqlalchemy] Re: POSTGRE Error with scoped sessions.
Ok, was just curious if anyone else had this error. On Wed, Jan 7, 2009 at 7:52 PM, Michael Bayer mike...@zzzcomputing.comwrote: That doesnt appear to be within SQLAlchemy. This might just be too much load for psycopg2 / your Python interpreter ?There's not much else to suggest here without a lot more context.

[sqlalchemy] Re: ORM relations...
I am not sure based on the project if I can have a module that imports both
of them. How can I use the string based ForeignKey? I may be doing it in
correctly because it says the table does not exist that I try to reference.

ForeignKey accepts strings to remove the inconvenience of handling
circular imports. Both dependent tables will need to be present

object is first used, though, so another module that imports both
queue and filequeue would be best.

Any ideas?

[sqlalchemy] Re: ORM relations...
I have a py file that creates my tables. It does MetaData =
queue.metadata. metadata.create_all(). That's all I do with MetaData. Is
there additional table setup I need to be doing?
On Tue, Dec 23, 2008 at 12:24 PM, Michael Bayer mike...@zzzcomputing.comwrote:
thats because both Table objects need to be present in the MetaData when
used. Ultimately your application can't run unless both queue and
filequeue have been imported in some way.

[sqlalchemy] Re: cascade
code:
queue_table = Table(
'QUEUES', metadata,
Column('QUEUEID', Integer, autoincrement=True, primary_key=True),
Column('JOBNUM', String(48), ForeignKey('JOBS.JOBNUM',
onupdate=CASCADE, ondelete=CASCADE)),
Column('SCHEDID', String(48), ForeignKey('SCHEDULES.SCHEDID')),
Column('DATE', DateTime),
Column('STATUS', Integer)) # 0 sched 1 Ignore 2 Evalling 3 Running 4
Unsched 5 Error
mapper(queue, queue_table, properties=dict(parent=relation(queue,
backref='job')))
In MSSQL the cascade entries for those tables are set to none and my app
also generate this:
many-to-many relation, 'secondaryjoin' is needed as well. % (self))
sqlalchemy.exc.ArgumentError: Could not determine join condition between
parent/
child tables on relation queue.parent. Specify a 'primaryjoin' expression.
If
this is a many-to-many relation, 'secondaryjoin' is needed as well.
