Order By का use records को sort करने के लिए किया जाता है , आप किसी भी column का use sorting के लिए कर सकते हैं।
Ascending order में record select करने के लिए ASC और descending order के लिए DESC का use किया जाता है , By Default Table से सभी records ascending order में ही आते हैं।
# import connector class from mysql module.
import mysql.connector as myconn
mydb = myconn.connect(
host = 'localhost',
user = 'root',
password = '',
database = 'python_db'
)
db_cursor = mydb.cursor()
# sort records in descending order.
query = "SELECT * FROM users ORDER BY id DESC"
db_cursor.execute(query)
rows = db_cursor.fetchall()
for row in rows : print(row)
