MySQL server is an open-source relational database management system which is a major support for web-based applications. Databases and related tables are the main component of many websites and applications as the data is stored and exchanged over the web. In order to access MySQL databases from a web server we use various modules in Python such as PyMySQL, mysql.connector, etc.
In this article, we are going to get the number of rows in a specific MySQL table in a Database. First, we are going to connect to a database having a MySQL table. The SQL query that is going to be used is:
SELECT * FROM table-name
And finally, display the number of rows in the table.
Below are some programs which depict how to count the number of rows from a MySQL table in a Database:
Example 1
Below is the table Lazyroardemo in database geek which is going to be accessed by a Python script:
Below is the program to get the number of rows in a MySQL table:
Python3
# import required modules import pymysql pymysql.install_as_MySQLdb() import MySQLdb # connect python with mysql with your hostname, # username, password and database db= MySQLdb.connect("localhost", "root", "", "geek") # get cursor object cursor= db.cursor() # get number of rows in a table and give your table # name in the query number_of_rows = cursor.execute("SELECT * FROM Lazyroardemo") # print the number of rows print(number_of_rows) |
Output:
Example 2:
Here is another example to get the number of rows from a table in a given database, below is the table scheme and rows:
Below is the python script to get row count from the table TechCompanies:
Python3
# import required modules import pymysql pymysql.install_as_MySQLdb() import MySQLdb # connect python with mysql with your hostname, # username, password and database db= MySQLdb.connect("localhost", "root", "", "techLazyroar") # get cursor object cursor= db.cursor() # get number of rows in a table and give your table # name in the query number_of_rows = cursor.execute("SELECT * FROM techcompanies") # print the number of rows print(number_of_rows) |
Output:
