如何进行python数据库查询？（实例解析）

#!/usr/bin/python

# -*- coding: UTF-8 -*-

import MySQLdb

# 打开数据库连接

db = MySQLdb.connect("localhost", "testuser", "test123", "TESTDB", charset='utf8' )

# 使用cursor()方法获取操作游标

cursor = db.cursor()

# SQL 查询语句

sql = "SELECT * FROM EMPLOYEE \

       WHERE INCOME > '%d'" % (1000)

try:

   # 执行SQL语句

   cursor.execute(sql)

   # 获取所有记录列表

   results = cursor.fetchall()

   for row in results:

      fname = row[0]

      lname = row[1]

      age = row[2]

      sex = row[3]

      income = row[4]

      # 打印结果

      print "fname=%s,lname=%s,age=%d,sex=%s,income=%d" % \

             (fname, lname, age, sex, income )

except:

   print "Error: unable to fecth data"

# 关闭数据库连接

db.close()

fname=Mac, lname=Mohan, age=20, sex=M, income=2000
