how do i ping mysql using mysql alchemy and python?
Use mysqlshow to see if MySQL is running as expected.
http://dev.mysql.com/doc/refman/5.1/en/mysqlshow.html
Assure that SQLAlchemy has supprt for MySQL.
http://www.sqlalchemy.org/docs/05/dbengine.html#supported-dbapis
Use a simple query through SQLAlchemy.

I am currently connecting django with MySQL using mysqlclient module,can I use mysql connector which is used in python to connect with MySQL database, here in django to enter deal with MySQL database
I didn't actually tried it.did anyone have tried it
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
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 am learning Python / Flask. Now I am at the point where I am learning Flask with MySQL Database. I read lots of posts about using Flask with databases and most of them suggest to use SQLAlchemy. I tried to read about SQLAlchemy, but I didn't like that because I prefer building and executing SQL queries and creating tables in the database only. Is there any way that I can take full benefit of using Flask with MySQL Database without SQLAlchemy?
Please suggest.
You don't have to use SQLAlchemy, no. You just have to connect to the database in Flask and execute your queries manually.
This question is about how to connect to MySQL with Python, and the official docs go over creating a site with a SQLite database. Modify the examples provided there with your MySQL connection.
