Hi All.
I have a datetime column in my model.
If I do an .order_by I get year-month-day

Thanks,
Frans.

you'd need to use SQL functions that break the datetime into its component
parts, and order by them.
such as:
order_by(func.datepart(MONTH, my_date_col), func.datepart(DAY,
my_date_col), func.datepart(YEAR, my_date_col))
datepart routines vary by database backend with very little cross

If I use InnoDB, the end result of used is 0 in all cases. If I don't and
use MyISAM, the end result of used is 1 in all cases, regardless of whether

Hello,
Thanks again for the quick reply!
I tried to isolate all the mapper columns to try to make it less
confusing, now I know that was not a good idea.
orm.mapper(User, user, properties={
'id': user.c.ID,
'_first_name': user.c.FirstName,
'_middle_name':

Face palm.. missed the forest for the trees.
Does this mean both tables would need to be InnoDB ?

Okay, so I implemented join(A, B).alias(), but I can't seem to access the
columns of the aliased table. Here is my code:
session = sessionfactory()
combined_1 = join(DiskFile, Header).alias()

yah MySQL doesn't really operate with a mixture.

Hi Michael,
Thanks for your quick reply.
I understand.
I am using SQLite as the engine.
I have not found the functions needed in the doc.

Not sure what you mean, as I've seen hybrid setups before.
In any case, thanks for helping me narrow this down. I need to decide
whether I'll need real transactions here. Despite being an oversight
on my part, do you think perhaps the docs for rollback / commit should
mention DB support ? I did
