I want to connect to a IBM Netezza server using SQLalchemy. I do that using the create_engine("----") command in which I need to specify a dialect. I can not find a dialect that supports IBM netezza. Is there a way of doing this or should I switch over to pyodbc?
Thank you.

I've built 2 websoftwares one with .Net and MSSQL server, the other with Django and MySQL. Now I want to transfer datas which falls in MSSQL to MySQL automatically. Is it possible to build an API for that?? I've no idea how to do it. Thanks in advance.
I'm pretty new to the AWS platform. I want to Fetch data from RDS MYSQL Database to my Python application using API. I couldn't find any relevant tutorial to achieve this task. It will be awesome If you could guide me or send a proper tutorial.

This is because such operation is not supported. To connect to your RDS database and get its data you have to use regular mysql tools, such as mysql cli, phpmyadmin or mysql workbanch.
You can only use AWS API for Mysql if you are using Aurora Serverless and its data api.
I am trying execute Python script from RDS SQL Server 15 version but I didn't find any documentation around this in AWS Will it be possible to do this?
Unfortunately that is not possible as of now. RDS for SQL Server is just Relational Database Service and it does not allow you to execute any program on the RDS instance, except for T-SQL programmability stored within your SQL Server database (triggers, stored procedures, etc).
I want to use MySQL in flask, and one config is
app.config['SQLALCHEMY_DATABASE_URI'] = "mysql+pymysql://user:password#127.0.0.1:3306/db"
If I use mysql+pymysql, it can work
But when I only use mysql, the erroe message like this
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
But in my code, I don't import pymysql, so what is the pymysql and why need use that can work
I know pymysql is a moudle
Thanks your reply!
The create_engine function (which is what uses the URL given in the config), requires you to give it a "dialect". A "dialect" is the name of the underlying database engine that SQLAlchemy is connecting to.
However, since many databases have multiple different clients (in Python these implement DBAPI), so in many cases (such as for the mysql dialect) you're required to give the name of the client you want SQLAlchemy to use. In this case, you're asking it to use the pymysql library to actually handle connectivity with MySQL.
SQLAlchemy 1.3 supports the following dialect/DBAPI-libraries for connecting to MySQL:
mysqlclient (maintained fork of MySQL-Python)
PyMySQL
MySQL Connector/Python
CyMySQL
OurSQL
Google Cloud SQL
PyODBC
zxjdbc for Jython
What is the best way to access sql server from python is it DB-API ?
Also could someone provide a such code using the DB-API how to connect to sql server from python and excute query ?
See pyodbc - Python Database API Specification v2.0 implementation. Works great.
Additionally you can use it with other databases. If using with SQL Server 2008, make sure you use Native Driver if you need to support new DATE data types.
See pymssql It is a DB-API module for MS Sql Server and would be the most pythonic way. The documentation includes examples.
If on a Windows OS you could also use OLEDB through COM which will not require any thing else to be installed on the client.
Also if you use Iron Python you can use the .Net APIs

how to connect to sql server from python and excute query ?
This hello world snippet pretty much shows you the common way how to connect with SQL server in Python with an DBI 2.0 database interface module.
