Install MySQL Driver. Python needs a MySQL driver to access the MySQL database. In this tutorial we will use the driver "MySQL Connector". We recommend that you use PIP to install "MySQL Connector". PIP is most likely already installed in your Python environment. Navigate your command line to the location of PIP, and type the following. Create a MySQLUtil instance to insert json into mysql. Here we use a python MySQLUtil class to operate mysql.
The class is in: Python Select, Insert, Update and Delete Data from MySQL: A Completed Guide. We can connect mysql using MySQLUtil instance first. mysql = MySQLUtil() ecun.school592.rutDB(host ='localhost', user = 'root', psw = '', db_name = 'test').

read_sql requires both a query and the connection instance cnxn, like so. data = ecun.school592.ru_sql("SELECT TOP() * FROM customers", cnxn)Author: James Briggs. Python Database API (Application Program Interface) is the Database interface for the standard Python. This standard is adhered to by most Python Database interfaces. There are various Database servers supported by Python Database such as MySQL, GadFly, mSQL, PostgreSQL, Microsoft SQL Server In Python, a tuple containing a single value must include a comma.
For example, ('abc') is evaluated as a scalar while ('abc',) is evaluated as a tuple. In most cases, the executemany() method iterates through the sequence of parameters, each time passing the current parameters to the the execute() method.
