Prerequisite: Python: MySQL Create Table
In this article, we show how to concatenate column values of a MySQL table using Python. We use various data types in SQL Server to define data in a particular column appropriately. We might have requirements to concatenate data from multiple columns into a string
Concatenating Coloums means that one is merging column data and showing it into a single column. This can also be done in MySQL using the CONCAT() function, but we are using a Python Program to concatenate multiple columns. MySQL Connector-Python module is an API in python for communicating with a MySQL database.
We are going to use this database:
How to Concatenate Column Values of a MySQL Table:
Syntax: SELECT Concat(Coloumn Name 1, Coloumn Name 2) AS fulldetail FROM Table_Name
How to Concatenate Column Values of a MySQL Table Using Python:
This example shows the Concatenation of a column. Steps are as follows:
- Use connect() function to establish a connection with the database server. Pass the host, user (root or your username), password (if present), and database parameters to connect() method.
- Then to create a cursor object, use the cursor() function.
- Execute the upper disused syntax for the Person table.
cursor.execute(“SELECT Concat(Coloumn Name 1, Coloumn Name 2) AS fulldetail FROM Table_Name”)
