I'm sorry sqlalchemy hasn't fully clicked for me yet. I'm still stuck on
this.
A I meant to be translating the sql that Michael has suggested into an ORM
query?
This is as far as I have got which results in :
NameError: name 'Issues' is not defined
Even then I still don't see how to get the "where" clause into the select.
from sqlalchemy import Column, String, Integer, DateTime, Boolean
from db_global import db
from sqlalchemy.sql import func, select
class Issues(db.Base):
__tablename__ = 'issues'
id = Column(String, primary_key=True)
thread_id = Column(String, nullable=False)
sequence_number = Column(Integer,
default=select([func.coalesce(func.max(Issues.sequence_number) + 1, 1)]))
