用plsql怎樣連接mysql？

看了web.py源碼，關于連接數據庫的函數如下(webpy/web/db.py)：

1133 _databases = {}1134 def database(dburl=None, **params):1135 """Creates appropriate database using params.1136 1137 Pooling will be enabled if DBUtils module is available. 1138 Pooling can be disabled by passing pooling=False in params.1139 """1140 dbn = params.pop('dbn')1141 if dbn in _databases:1142 return _databases[dbn](**params)1143 else:1144 raise UnknownDB, dbn可以看出的是，dburl的確沒有起到作用，注釋里面也說了： Creates appropriate database using params。不過一般連接mysql數據庫通過以下參數連接的話，應該是可以連接上的吧。（我沒有試過遠程，所以不敢肯定。）import webdb = db.database( dbn="mysql", db="dbname", host="host", port=3306, user="user", pw="password")
