MariaDB is an open source Database Management System and its predecessor to MySQL. The pymysql client can be used to interact with MariaDB similar to that of MySQL using Python.
In this article we will look into the process of querying data from a table of the database using pymysql. To query data use the following syntax:
Syntax :
- In order to select particular attribute columns from a table, we write the attribute names.
SELECT attr1, attr2 FROM table_name
- In order to select all the attribute columns from a table, we use the asterisk ‘*’ symbol.
SELECT * FROM table_name
Example 1 :
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 * FROM PRODUCT"
cur.execute(query)
rows = cur.fetchall()
conn.close()
for row in rows :
print(row)
Output :
The above program illustrates the connection with the MariaDB database 'GFG' in which host-name is localhost, the username is 'user' and password is 'your password'.
Example 2 :
import pymysql
# Create a connection object
conn = pymysql.connect('localhost', 'user', 'password', 'database')
# Create a cursor object
cur = conn.cursor()
query = f"SELECT price,PRODUCT_TYPE FROM PRODUCT"
cur.execute(query)
rows = cur.fetchall()
conn.close()
for row in rows :
print(row)
Output :
