Hi,
I'd like to know if there is some profiling support in SQLAlchemy. It would be
nice if there would be some data accompanying SQL statements in the logfiles
that can be used to optimize the RDB-part of the application (e.g. lazy/eager
loading, specifying queries, creating indexes etc.).
Hi,
In one of my database tables I have a varchar that is mapped to an object with
a string attribute. This specific varchar should however be represented by a
certain Python object, therefore it would be very handy, if there would be a
way to automatically load/represent this data. Is there

Here you're holding onto open cursors with 'something ==
ordinateurs.fetchone()'. Either explicitly close() the two result sets
you're accessing with fetchone() or remove your reference to the rows
and python gc will get around to closing the cursors at some point.
ok thanks.
Don't know how you are rendering this; but if this a web app, you
could make an Ajax call which fires off the query, draw the grey bar,
and have the callback from the Ajax query then render the results
when they are ready..

Im not sure about creation, but I've not had any problems using

SQLAlchemy 0.3 and PostgreSQL.

Turns out the issue was in the PK declaration for the table
I think it might be more historical than anything else. Back when what is
now filter() was a single argument to the select() call, on the SQL-API
side, and there couldn't take any additional arguments, as the select() call
was already pretty heavy with keyword arguments and it was easy to get
I believe the 0.4 unit tests have profiling support, have a look there.
