python實(shí)現(xiàn)讀取mysql查詢結(jié)果值的輸出方式

本文主要給大家介紹python實(shí)現(xiàn)讀取mysql查詢結(jié)果值的輸出方式，文章內(nèi)容都是筆者用心摘選和編輯的，具有一定的針對性，對大家的參考意義還是比較大的，下面跟筆者一起了解下python實(shí)現(xiàn)讀取mysql查詢結(jié)果值的輸出方式吧。 

#!/bin/python

#coding=utf-8

import MySQLdb

import time

import sys

import MySQLdb.cursors

# 加上字符集參數(shù)，防止中文亂碼

print "---------TOP OS SLAVE 10--------"

conn = MySQLdb.connect(host="XXXX",db="mysql",user="user",passwd="password",port=338

0,charset="utf8")

cursor = conn.cursor() 

query = "select distinct t.user_host,t.sql_text from mysql.slow_log t  where t.query_time>5 and t.start_time>=SUBDATE(CURDATE(),DATE_FORMAT(CURDATE(),'%w')+3) and t.start_time<SUBDATE(CURDATE(),DATE_FORMAT(CURDATE(),'%w')-4) ORDER BY t.query_time DESC limit 10"

cursor.execute(query)

r = cursor.fetchall()

for a in r:          

   user_host =a[0]

   sql_text =a[1]                 

   print "\n"

   print "%s\t%s" %(user_host,sql_text) 

conn.close()

以數(shù)組形式輸出查詢結(jié)果。

函數(shù)形式多組查詢

#!/bin/python

#coding=utf-8

import MySQLdb

import time

import sys

import MySQLdb.cursors

def select():   #定義函數(shù)

    query = "select distinct t.user_host,t.sql_text from mysql.slow_log t  where t.query_time>5 and    

    t.start_time>=SUBDATE(CURDATE(),DATE_FORMAT(CURDATE(),'%w')+3) and t.start_time<SUBDATE(CURDATE(),D

ATE_FORMAT(CURDATE(),'%w')-4) ORDER BY t.query_time DESC limit 10"

    cursor.execute(query)

    r = cursor.fetchall()

    for a in r:

      user_host =a[0]

      sql_text =a[1]

      print "%s\t%s" %(user_host,sql_text)

      print "\n"

    conn.close()

print('\033[35m')

print "---------TOP OS SLAVE 10--------"

print('\033[0m')

conn=MySQLdb.connect(host="xxxxx",db="mysql",user="user",passwd="password",port=3380,charset="utf8")

cursor = conn.cursor()

select()

print('\033[35m')

print "---------TOP RETAIL SLAVE 10--------"

print('\033[0m')

conn=MySQLdb.connect(host="xxxxxx",db="mysql",user="user",passwd="password",port=3382,charset="utf8")

cursor = conn.cursor()

select()
