Dear all,
I am writing an application to scan a directory system and store
metadata in DB.
For each directory I create a separate process in which scanning and
metadata feed is performed.
Now I have following problems:
1) I am forced to start a session in each process and bind them for
the engine
I'm trying to diagnose an issue with temporary tables, so I cranked up
the debug levels to DEBUG.
I noticed something strange:

Sorry for late reply, but I was rather busy with real life work.
I believe your code will be useful for me and for others too.

hi all,
I've been trying to work out some SQLalchemy code to query two datetime
columns and choose the one closest in time. I have some code that does this,
but it requires using PostgreSQL and looks a little messy:
query = query.order_by(ABS(EXTRACT(EPOCH FROM (header.utdatetime -
Yeah, that's what we do right now.

Hi all,
I have an application replying on sqlalchemy that deals with many
recursive methods. We manipulate complex graphs.
I have tests that validates we get the expected results for each
method.
Still, many optimization might be done to the code.

you can emit that exact SQL using func.abs() in conjunction with the extract()
function, which is a standalone SQLA construct.
from sqlalchemy import func, extract

Hi Folks,
I was hoping to still be able to get guidance on creating my
UserDefinedType.
If I just knew exactly what the purpose of the bind and result
processes were
supposed to be, I'm sure I could look it up from there.

Assuming you're using types that are provided by the database (i.e. VARCHAR,
ARRAY, INTEGER, etc.), you use a TypeDecorator to add some kind of in-Python
marshalling behavior to some Python type.
