Is it possible 开发者_如何学Pythonto connect any database from flex directly?
You can use asSQL as mentioned by michael, or use the Adobe Air runtime.
However, this must be said about using this library: It is EXTREMELY insecure to have a straight database connection from the client unless it's from Adobe Air since the db is local.
You don't want to send your username/password over the internet to connect to a database unless you really don't care about the data or security of your data. I would recommend you use a middleware solution, like PHP or Java that interfaces your database for your client to get the data it needs.
Not unless you use Adobe AIR for desktop at which time you'd be using the SQLLite api's to create/connect to a sqlite database file.

Anything else is going to require a back end service to handle such transactions.
You may try asSQL.
