MySQL Order By

结果排序

请使用 ORDER BY 语句按升序或降序对结果进行排序。

ORDER BY 关键字默认按升序对结果进行排序。若要按降序对结果进行排序，请使用 DESC 关键字。

实例

以字符顺序对姓名进行排序，结果:

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  password="yourpassword",
  database="mydatabase"
)

mycursor = mydb.cursor()

sql = "SELECT * FROM customers ORDER BY name"

mycursor.execute(sql)

myresult = mycursor.fetchall()

for x in myresult:
  print(x)
运行实例 »

  user="yourusername",
  password="yourpassword",
  database="mydatabase"
)

mycursor = mydb.cursor()

sql = "SELECT * FROM customers ORDER BY name DESC"

mycursor.execute(sql)

myresult = mycursor.fetchall()

for x in myresult:
  print(x) 运行实例 »
