Mysql Connector Python Install

  1. The disadvantage of using mysqlconnector module is that the its API is different than mysql.connector, and closely resembles to MySQL C client library. Since all the examples we have seen so far, uses pure Python implementation of Connector/Python, the rest of the lesson only discusses how to use the C extension via the mysqlconnector module.
  2. I found no way to install mysql-connector-python that I used with windows. For python 3.4 I used the command. Sudo python3 -m pip install pymysql for python 2.7 you can use following commands. Sudo apt-get install python-mysqldb. Sudo apt-get install python-pip pip install pymysql.

4.4 Verifying Your Connector/Python Installation

MySQL Connector/Python provides you with the MySQLCursor class, which instantiates objects that can execute MySQL queries in Python. An instance of the MySQLCursor class is also called a cursor. Cursor objects make use of a MySQLConnection object to interact with your MySQL server. Import mysql.connector from mysql.connector.cursor import MySQLCursor from pprint import pprint db = mysql. Connect (optionfiles = 'my.conf', usepure = True) cursor = db. Cursor # query with format parameter style sql1 = 'select version' sql2 = 'select Code, Name, Region, Population, Continent from country where Continent=%s. Mysql-connector-repackaged - MySQL driver written in Python mysql-connector-python-rf - MySQL driver written in Python mysql-connector-python - MySQL driver written in Python This is very confusing. Anybody knows which one I should use and why? Thanks for your help.

Connector/Python runs on any platform where Python is installed. Python comes preinstalled on most Unix and Unix-like systems, such as Linux, macOS, and FreeBSD. On Microsoft Windows, a Python installer is available at the Python Download website. If necessary, download and install Python for Windows before attempting to install Connector/Python.

Connector/Python requires python to be in the system's PATH and installation fails if python cannot be located. On Unix and Unix-like systems, python is normally located in a directory included in the default PATH setting. On Windows, if you install Python, either enable Add python.exe to Path during the installation process, or manually add the directory containing python.exe yourself.

For more information about installation and configuration of Python on Windows, see Using Python on Windows in the Python documentation.

Connector/Python implements the MySQL client/server protocol two ways:

  • As pure Python; an implementation written in Python. Its dependencies are the Python Standard Library and Python Protobuf >= 3.0.0.

    EL7 and Ubuntu 16.04 do not provide Python Protobuf 3+ making the pure Python version unavailable on those platforms; use the C Extension variant there instead. You may have to --force the installation but may not use use_pure=True.

  • As a C Extension that interfaces with the MySQL C client library. This implementation of the protocol is dependent on the client library, but can use the library provided by MySQL Server packages (see MySQL C API Implementations).

Neither implementation of the client/server protocol has any third-party dependencies. However, if you need SSL support, verify that your Python installation has been compiled using the OpenSSL libraries.

By default, EL8 and Debian 10 supports TLSv1.2 and later when the policy level is set to DEFAULT. To support TLSv1 and TLSv1.1, the policy needs to be changed to LEGACY. This means that a default EL8/DEB10 setup cannot make connections with TLSv1 and TLSv1.1 using the C-extention. Other platforms may change their default behavior in the future.

Installation of Connector/Python is similar on every platform and follows the standard Python Distribution Utilities or Distutils. Distributions are available in native format for some platforms, such as RPM packages for Linux.

Python terminology regarding distributions:

Mysql Connector Python Install

  • Built Distribution: A package created in the native packaging format intended for a given platform. It contains both sources and platform-independent bytecode. Connector/Python binary distributions are built distributions.

  • Source Distribution: A distribution that contains only source files and is generally platform independent.
