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 -
, which is a standalone SQLA construct.
from sqlalchemy import func, extract
func.abs(extract('epoch', header.udatetime - self.header.udatetime))

I want to do a self join on combined but it wont let me. Essensially,
I want to join two different tables, and create aliases so I can
compare one column and make sure that each item in the column is
uniqe. If there are duplicates, I want my piece of code to show the
duplicates. Combining join
