  • 【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
