Python MySQL ORDER BY

排序结果

使用ORDER BY语句对结果进行升序或降序排序。默认情况下，ORDER BY关键字对结果进行升序排序。要按降序对结果进行排序，请使用DESC关键字。

按名称的字母顺序对结果进行排序：结果：

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="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)

降序排序

使用DESC关键字以降序对结果进行排序。

按名称的字母顺序对结果进行反向排序：

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="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)
