The Limit clause is used in SQL to control or limit the number of records in the result set returned from the query generated. By default, SQL gives out the required number of records starting from the top but it allows the use of the OFFSET keyword. OFFSET allows you to start from a custom row and get the required number of result rows.
Syntax :
SELECT * FROM tablename LIMIT limit; SELECT * FROM tablename LIMIT limit OFFSET offset;
The following programs will help you understand this better.
Database in use:
Example 1: program to display only 2 records
Python3
import pymysql # Create a connection object # IP address of the MySQL database server Host = "localhost" # User name of the database server User = "user" # Password for the database user Password = "" database = "GFG" conn = pymysql.connect(host=Host, user=User, password=Password, database) # Create a cursor object cur = conn.cursor() query = f"SELECT price,PRODUCT_TYPE FROM PRODUCT WHERE price > 10000 LIMIT 2" cur.execute(query) rows = cur.fetchall() for row in rows : print(row) conn.close() |
Output :
Example 2: program to start from the second record and display the first two records
Python3
import pymysql # Create a connection object conn = pymysql.connect('localhost', 'user', 'password', 'database') # Create a cursor object cur = conn.cursor() query = f"SELECT * FROM PRODUCT LIMIT 2 OFFSET 1" cur.execute(query) rows = cur.fetchall() for row in rows : print(row) conn.close() |
