Jun 28, 2013 MySQLdb is a Python DB API-2.0-compliant interface; see PEP-249 for details. For up-to-date versions of MySQLdb, use the homepage link. Supported versions:. MySQL versions from 3.23 to 5.5; 5.0 or newer recommended. MariaDB should also work. Python versions 2.4-2.7; Python 3 support coming soon. ZMySQLDA is a Database Adapter for Zope2. If you need 1.2.x versions (legacy Python only), use pip install MySQL-python. Note: Some dependencies might have to be in place when running the above command. Some hints on how to install these on various platforms: Ubuntu 14, Ubuntu 16, Debian 8.6 (jessie) sudo apt-get install python-pip python-dev libmysqlclient-dev Fedora 24.

In this tutorial you will learn how to use a widely used database management system called MySQL in Python. You do not need any previous knowledge of MySQL to use this tutorial, but there is a lot more to MySQL than covered in this short introductory tutorial.

MySQL tutorial
Data is stored in a collection of tables with each table consisting of a set of rows and columns. This is similar to how data is stored in SQLite. To interact with the data stored in tables we use a special-purpose programming language called SQL.

Step 1: Install MySQL
First you must install a MySQL driver, use the specific installation method below.

On Windows:
Install MySQLdb using the installer.

Ghostscript 9.50 Full. Ghostscript 9.27 was released April 4, 2019. Below is a signed and notarized Macintosh install package for this version of Ghostscript. The package works on macOS Sierra and above, for Intel. In case of trouble, you can revert to Ghostscript 9.26 by just installing on top of Ghostscript 9.27. Ghostscript 9.27. Ghostscript mac os x Artifex GSView 6 - a previewer for MS-Windows, Linux and Apple OS X Ghostgum GSview 5 - an old previewer for MS-Windows. There is no further development planned for this version.

MacOS App Bundle of Octave 4.0.3 (with GUI) (OS X 10.9+) Package Managers. All package managers below are given in alphabetical order. The Octave developers do not recommend a certain package manager. Homebrew → Link to Octave package there.

On Linux:
Install MySQLdb using:

depending on your version.

On Mac:
Follow the installation instructions from stackoverflow

MySQL server has to be running before going to the next step.

Step 2: Setup the database

Make sure you have database access, from the command line type:

MySQL will then ask your password. Type these commands:

We go on the create the table:

Then we can insert data into the table (these are SQL queries):

You can now grab all records from the table using a SQL query:

Step 3: Getting the data from Python
You can access the database directly from Python using the MySQLdb module.

Summary: in this tutorial, you will learn how to find duplicate values of one or more columns in MySQL.

Mysql Python 2.6

Data duplication happens because of many reasons. Finding duplicate values is one of the important tasks that you must deal with when working with the databases.

Setting up a sample table

First, create a table named contacts with four columns: id, first_name, last_name, and email.

Second, inserts rows into the contacts table:

Third, query data from the contacts table:

In the contacts table, we have some rows that have duplicate values in the first_name, last_name, and email columns. Let’s learn how to find them.

Find duplicate values in one column

The find duplicate values in on one column of a table, you use follow these steps:

  1. First, use the GROUP BY clause to group all rows by the target column, which is the column that you want to check duplicate.
  2. Then, use the COUNT() function in the HAVING clause to check if any group have more than 1 element. These groups are duplicate.

The following query illustrates the idea:

By using this query template, you can to find rows that have duplicate emails in the contacts table as follows:

This picture shows the output of the query that shows the duplicate emails:

Find duplicate values in multiple columns

Sometimes, you want to find duplicate rows based on multiple columns instead of one. In this case, you can use the following query:

Rows are considered duplicate only when the combination of columns are duplicate therefore we used the AND operator in the HAVING clause.

For example, to find rows in the contacts table with duplicate values in first_name, last_name, and email column, you use the following query:

The following illustrates the output of the query:

In this tutorial, you have learned how to find duplicate rows based on value of one or more columns in MySQL.
