把sqlalchemy的result当成struct使用

>>> rst = db.query( "select * from adv_urlqueue where flg = '0'" )

s_sql = [select * from adv_urlqueue where flg = '0']

2008-04-18 13:29:17,030 INFO sqlalchemy.engine.base.Engine.0x..90 select * from adv_urlqueue where flg = '0'

2008-04-18 13:29:17,046 INFO sqlalchemy.engine.base.Engine.0x..90 None

>>> rst.rowcount

1L

从这里可以看到已经取出数据.

查看下rst的一些属性和方法吧

>>> dir( rst )
