Limit Number of Rows from Table in Python MySQL
Python MySQL - Limit number of rows selected from table
To select limited number of rows from a MySQL table in Python program,
- Create a connection to the MySQL database with user credentials and database name, using connect() function.
- Get cursor object to the database using cursor() function.
- Call execute() function on the cursor object, and pass the SELECT FROM table query with LIMIT clause.
- Call fetchall() function on the cursor object. The function returns an iterator to the records in the table. Each record is a tuple.
Example
Consider that there is a schema named mydatabase
in MySQL. The credentials to access this database are, user: root
and password: admin1234
, and there is a table named fruits
in mydatabase
.
In the following program, we select the rows from fruits
table, but limit the number of records to two.
Python Program
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="root",
password="admin1234",
database="mydatabase"
)
mycursor = mydb.cursor()
mycursor.execute("SELECT * FROM fruits LIMIT 2")
myresult = mycursor.fetchall()
for row in myresult:
print(row)
Output
('Apple', 25, 'Canada')
('Avocado', 37, 'Mexico')
Summary
In this tutorial of Python Examples, we learned how to limit the number of records in the selection from a table in MySQL database, from a Python program.
