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 -
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
func.abs(extract('epoch', header.udatetime - self.header.udatetime))
