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)
