Most custom dialects are written by forking an existing dialect.
Unfortunately, a dialect can not accomplish what you want to do.
SqlAlchemy Dialects are used to generate SQL, which is then passed to the
database via a DBAPI driver.
For example, when someone uses PostgreSQL with SQLAlchemy,

The Flask-Sqlalchemy package handles all the session stuff automatically in

explicitly, but it is utilizing the session implicitly.

Many users with similar experiences ultimately traced the issue to an

I think you misunderstand `exists()` in SQLAlchemy and SQL. `exists()` is
a convenience function to create a SQL `EXISTS` clause, which is an
operator used for filtering subqueries.
The 'from_exists' is just a subquery. It is supposed to be used within a

The first two things I would look into:

the same as the basic operating system install invoked in your terminal.
Sometimes that version does not have the functionality you need.
2. Check the transactional isolation

characters in it. People have had similar issues in the past. If that is
the case, there are some recent threads in this group and on the github

relationships (see https://docs.sqlalchemy.org/en/13/orm/cascades.html)

I realized I could scrap this entire functionality and replace it with
something else.
The use-case was trying to detect the backup renewal options for SSL
Certificates if the private key Or account key is revoked. (foo is an ACME
order if available, bar is the certificate).
It’s been a while since I’ve worked on stuff like this, but IIRC the simplest
way was to use a function that accepts an ID and to flush in SqlAlchemy before
executing it. Then you select the necessary row fields within the sql function,
instead of passing args in or trying to pass a row in.
I have two classes where one f-keys onto another.
Things work perfectly:
class Foo(Base):
id = Column(Integer, primary_key=True)
bar_id = Column(Integer, ForeignKey("bar.id"), nullable=True)
bar = relationship(
"bar",
primaryjoin="Foo.bar_id==Bar.id",
There are two related concerns on this concept:
* protecting your credentials in source code
* protecting your credentials on the server
For the first concern, I like to use encryption management tools like
Blackbox (https://github.com/StackExchange/blackbox)

By default, SqlAlchemy has `expire_on_commit=True`.
I'm going to poorly restate most of what Mike Bayer has told me in the
past: the rationale behind this- an active Session is supposed to mirror
the current state in the database; within a transaction we know the object
values are equal to
My first guess is two things are going on:
1. This is a behavior of `expire_on_commit` on the session. Once you
commit on the Primary database, the object is stale.
https://docs.sqlalchemy.org/en/13/orm/session_api.html
2. The session is then trying to read off a Secondary database, but the
It doesn't matter when the time is entered or what it is supposed to
reflect. The best option -- by a wide margin -- for storing any time
values is in a TIMESTAMP column, and for storing date+time values is in a
DATETIME column. These types of columns/fields/formats exist to streamline
data
The common approach to this situation is storing the data as a 24hour
timestamp in the database/sqlalchemy and converting it to a 12hour am/pm
for display/editing.
You could use a "12 hour" option and an enum column for am/pm or a string.
You're going to have a much easier time in the longterm
