paip.python连接mysql最佳实践o4

python连接mysql 还使用了不少时间...,相比php困难多了..麻烦的.. 而php,就容易的多兰..
python标准库没mysql库,只好第三方兰..
先看累挂..说MySQLdb...三,不行..
1. MySQLdb( MySQL-python 1.2.3)支持派森python 2.7的直接windows安装包，用的python 2.7的朋友可以使用，使用python 3.x的朋友就不支持了
2.还没二进制的安装包,..要源码编译..麻烦的..windows上要安装linux编译环境MinGW了..pass..

================mysql-connector-python
目前MySQLdb并不支持python3.x，网上找了一些方法，后来我还是偶然发现MySQL官方已经提供了MySQL连接器，而且已经有支持Python3.x的版本了。MySQL Connector/Python, a self-contained Python driver for communicating with MySQL servers. 这个用起来还是感觉比较顺手的。有二进制包了...
mysql-connector-python-1.1.6-py3.3.msi (111kb)

三,安装的时候儿要python了.俄的机器上有个python3.3.4了,绿色版本的..因为这个新不上...只好在安装了python3.3.5(20M),这才安上.安装到个D:\Python335\Lib\site-packages\mysql 里面兰..看累挂,都是py文件,没编译..

eric5里面f2 运行文件   D:\Python335\Python.exe D:\workSpacePython\halo.py ,三,说新不上mysql 模块..查看sys.path这个库加载的路线..
import sys, os
print( sys.path)
三是eric的路线
[‘‘, ‘D:\\workSpacePython‘, ‘D:\\Python334eric\\Lib\\site-packages\\eric5\\DebugClients\\Python3‘, ‘D:\\Python334eric\\python33.zip‘, ‘D:\\Python334eric\\DLLs‘, ‘D:\\Python334eric\\lib‘, ‘D:\\Python334eric‘, ‘D:\\Python334eric\\lib\\site-packages‘, ‘D:\\Python334eric\\lib\\site-packages\\win32‘, ‘D:\\Python334eric\\lib\\site-packages\\win32\\lib‘, ‘D:\\Python334eric\\lib\\site-packages\\Pythonwin‘]
只好不个那复制到个仄哈面儿,ok兰...

Python.exe D:\workSpacePython\getpath.py

===============例子代码

my_dict = { ‘a‘:1, ‘b‘:2 }
#然后敲"my_dict."，出不来字典的各个函数，ctrl+space也不行。
import sys, os
print( sys.path)
# 引入 MySQL 模組
#import MySQLdb
import mysql.connector

# 連接到 MySQL
#db = MySQLdb.connect(host="localhost", user="root", passwd="", db="dbc8")
#cursor = db.cursor()
user = ‘root‘
pwd = ‘‘
host = ‘127.0.0.1‘
db   = ‘dbc8‘
cnx = mysql.connector.connect(user=user, password=pwd, host=host, database=db)
cursor = cnx.cursor()

# 執行 SQL 語句
cursor.execute("SELECT * FROM grejx where 1=1 limit 30000")
#result = cursor.fetchall()

#print(result)
#[(‘abandon‘, ‘v./n.放弃；放纵‘, 2), (‘abash‘, ‘v.使害羞，使尴尬‘, 3), (‘abate‘, ‘v.减轻，减少‘, 4)]
# 輸出結果
#for record in result:
#   print( record[0] )

#print(cursor)
#MySQLCursor: SELECT * FROM grejx limit 3

homedirx=os.path.split(os.path.realpath(__file__))[0]
#sys.path.append(".")
#sys.path.append(homedirx)
#print( sys.path)

import pkg.strUtil
from pkg.strUtil import *
import strUtil2
from strUtil2 import *
#o44()
#strUtil2.o45()

conn2 = mysql.connector.connect(user=user, password=pwd, host=host, database=db)

cursorInsert = conn2.cursor()
import dicUtil
from dicUtil import *
#this must match field amout and order in sql
for (en, cn, id) in cursor:
    if(hasTsisin(cn)):
        tsisin=left_ByDot(cn)
        cnstr=right_ByDot(cn)
    else:
        tsisin="nonx."
        cnstr=cn
    cnstr=cnstr.replace("；", ",")
    cnstr=cnstr.replace("，", ",")

    cnstr_a=cnstr.split(",")
#    for index8 in range(len(list)):
#        print index8
#      print list[index8]
    print (" "+tsisin+"---"+cnstr)
    for index,v in enumerate(cnstr_a):
      # print ()index
      # print (v) strip
        sql=" insert into grejx_def (en,cn,nAdjV)values(‘@en‘,‘@cn‘,‘@adj‘)"
        sql=sql.replace("@en", trim(en)).replace("@cn", v.strip()).replace("@adj", tsisin.strip())
        print(sql)
        reslt=cursorInsert.execute(sql)

        print("---insert resl:")
        print(reslt)
        conn2.commit()
