Python 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",
- 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
请使用 DESC 关键字按降序对结果进行排序。
实例
按反转字母顺序对姓名的结果进行排序:
- 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)
