I'm trying to perform bulk extracts/loads from Oracle to MySQL using cx_Oracle and SQL Alchemy.

I found this example online and it works well for most data types, but fails from Blob data types:

I have about 43 tables and about 12 of them have BLOB data types.

I'm creating a Flask Blog using SQL-alchemy and Python. The blog is a blog for recipes where the users can rate the recipes. I get all the ratings to appear BUT I also want to get the average rating. I've tried this so far but I can't get it to work...

I always use SQL or NoSQL databases in my project and at my job, but now I am asked to use an object-oriented DB. I don't even know for what reason I should do that. Despite this fact, I google for OODBMS in python and can't see any easy way to use this approach. Now I think, that django ORM (and flask sql alchemy) are the simplest way to construct databases.

So, I have two questions:

1. What are the main benefits of using OODBMS instead of, e.x., Django ORM?

2. Is there a simple way to use OODBMS in flask and django?

I'm trying to use pytest-mock for mocking. This library is essentially a plugin/wrapper for mock and patch.

My problem is defined as:

I have an application (mymodule.py) that uses SQL Alchemy. Basically, there's a function that defines some objects from SQL Alchemy and returns a dictionary with those objects.

I am new to SQL Alchemy and need a way to run a script whenever a new entry is added to a table. I am currently using the following method to get the task done but I am sure there has to be a more efficient way.

I am using python 2 for my project and MS SQL as database.

Suppose my table is carData and I add a new row for car details from website. The new car data is added to carData. My code works as follows

I'm developing a python application where most of its functions will interact (create, read, update and delete) with a specific table in a MySQL database. I know that I can query this specific table with the following code:

I know this might be a level 0 question, but I'm stuck here

I'm using SQL Alchemy to get the sql result.

I have a use case, where I need create new queues at runtime, and also create consumers for those newly created queues. The queues created at runtime should be exclusive and auto-delete with an expiry time. I followed the pattern that is suggested over - here If I declare them to be both exclusive and auto-delete, without any x-expires argument it works. However, if I set it, I see an error message in the console, whenever the application tries to create a new queue at runtime. Looks like the argument name is wrong or may not be what spring internally expects. Just looking on how to set that expiry time. Below are my classes:

I'm new to SQLAlchemy and PostgreSql, so apologies for the newbie question. I'm trying to connect to a table in a remote PostgreSql server using flask-alchemy, and read all the table records. It doesn't have to be flask-sqlalchemy specifically, but I do need to read the table records.

The table has 3 records, but it always comes back as zero records when I step through the code.

I'm using python 3.7, visual studio code with an virtual environment in windows 10.
