def _get_server_version_info(self, connection):

overrides sqlalchemy.engine.interfaces.Dialect._get_server_version_info

overridden in sqlalchemy.dialects.firebird.fdb.FBDialect_fdb

Get the version of the Firebird server used by a connection.

Returns a tuple of (major, minor, build), three integers representing the version of the attached server.

Undocumented

def create_connect_args(self, url):

overrides sqlalchemy.engine.default.DefaultDialect.create_connect_args

overridden in sqlalchemy.dialects.firebird.fdb.FBDialect_fdb

Build DB-API compatible connection arguments.

Given a .URL object, returns a tuple consisting of a (*args, **kwargs) suitable to send directly to the dbapi's connect function. The arguments are sent to the .Dialect.connect method which then runs the DBAPI-level connect() function.

The method typically makes use of the .URL.translate_connect_args method in order to generate a dictionary of options.

The default implementation is:

def create_connect_args(self, url):
    opts = url.translate_connect_args()
    opts.update(url.query)
    return [[], opts]

Parameters
url	a `.URL` object
Returns
a tuple of `(args, *kwargs)` which will be passed to the `.Dialect.connect` method.

Parameters
dbapi_connection	a DBAPI connection, typically proxied within a `.ConnectionFairy`.
