【mysql】MySQLdb返回字典方法

来源：http://blog.csdn.net/zgl_dm/article/details/8710371

默认mysqldb返回的是元组，这样对使用者不太友好，也不利于维护
下面是解决方法

import MySQLdb
import MySQLdb.cursors

conn = MySQLdb.Connect (
host = 'localhost', user = 'root' ,
passwd = '', db = 'test', compress = 1,
cursorclass = MySQLdb.cursors.DictCursor, charset='utf8') // <- important
cursor = conn.cursor()
cursor.execute ("SELECT name, txt FROM table")
rows = cursor.fetchall()
cursor.close()
conn.close()

for row in rows：
    print row ['name'], row ['txt'] # bingo!

# another (even better) way is:

conn = MySQLdb . Connect (
host = ' localhost ', user = 'root' ,
passwd = '', db = 'test' , compress = 1)
cursor = conn.cursor (cursorclass = MySQLdb.cursors.DictCursor)
# ...
# results by field name
cursor = conn.cursor()
# ...
# ...results by field number

注意：如果同时安装了PyMySQL和MySQL-python库，会导致MySQL-python失效，只有pymsql可用

解决办法：

try:
    import pymysql as MySQLdb
except ImportError:
    import MySQLdb

这样就可以用一套代码搞定了
