[Python]Python操做/管理Mysql學習（一）

先肯定環境是否已支持MySQLdb模塊，若是沒有，請安裝，以下：
[root@bw-vm-soft ~]# wget http://jaist.dl.sourceforge.net/project/mysql-python/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz
[root@bw-vm-soft ~]# tar zxvf MySQL-python-1.2.3.tar.gz
[root@bw-vm-soft ~]# cd MySQL-python-1.2.3

修改site.cfg中的mysql_config路徑
vi site.cfg 
mysql_config = /usr/local/webserver/mysql/bin/mysql_config   （根據mysql安裝路徑而定）

[root@bw-vm-soft MySQL-python-1.2.3]# python setup.py build
[root@bw-vm-soft MySQL-python-1.2.3]# python setup.py install
確認安裝成功後

請在/etc/ld.so.conf添加/usr/local/webserver/mysql/lib/mysql，而後執行 ldconfig

以後就能夠進入正題，操做/管理Mysql了

例一、插入數據
###########################################################################
#!/usr/bin/env python
# _*_ coding:utf-8 _*_
import MySQLdb as mdb
import sys

con = mdb.connect('localhost','root','123123','pythontest')
with con:
    cur = con.cursor()
    cur.execute("CREATE TABLE IF NOT EXISTS \
        Users(Id INT PRIMARY KEY AUTO_INCREMENT, Name VARCHAR(25))")
    cur.execute("INSERT INTO Users(Name) VALUES('Richard shen')")
    cur.execute("INSERT INTO Users(Name) VALUES('Zhang san')")
    cur.execute("INSERT INTO Users(Name) VALUES('Li si')")
    cur.execute("INSERT INTO Users(Name) VALUES('Wang dongdong ')")
###########################################################################

例二、查看數據

#!/usr/bin/env python
#_*_coding:UTF-8 _*_
import MySQLdb as mdb
import sys

con = mdb.connect('localhost','root','123123','pythontest')

with con:
    cur = con.cursor()
    cur.execute("SELECT * FROM Users")
 
    numrows = int(cur.rowcount)
    for i in range(numrows):
        row = cur.fetchone()
        print row[0],row[1]
  
執行結果：
1 Richard shen
2 Zhang san
3 Li si
4 Wang dongdong

這是數據庫最基本的操做，之後學習中會繼續介紹相關內容~~如有好建議/問題，請聯繫~QQ羣:24967504
