Sybase stored procedures can return tabular results like a SQL query can. This is unlike stored procedures in Oracle (not sure about other DBMSs) I found (in 1.0.4) that I could not invoke such a procedure with the runQuery method. I developed the following subclasses that add a "callProc" method which calls the procedure and fetches the results. I could easily have added these methods to enterprise/adbapi.py but I don't like to run locally modified distributions so I went the subclass route for my needs. Thought I'd share this so that someone could possbly add it to the distribution. I used this with the Sybase module for Python from Object Craft[1] from twisted.enterprise import adbapi from twisted.internet import defer, threads class SybaseConnectionPool(adbapi.ConnectionPool): def __init__(self, dbapiName, *connargs, **connkw): apply(adbapi.ConnectionPool.__init__, (self, dbapiName) + connargs, connkw) def _callProc(self, args, kw): conn = self.connect() curs = conn.cursor() try: apply(curs.callproc, args, kw) result = curs.fetchall() curs.close() conn.commit() except: conn.rollback() return result def procedure(self, callback, errback, *args, **kw): threads.deferToThread(self._callProc, args, kw).addCallbacks( callback, errback) class SybaseAugmentation(adbapi.Augmentation): def __init__(self, dbpool): adbapi.Augmentation.__init__(self, dbpool) def callProc(self, *args, **kw): d = defer.Deferred() apply(self.dbpool.procedure, (d.callback, d.errback)+args, kw) return d The code to call a Sybase stored proc then looks like (patterned after the example in the Twisted Book): dbpool = SybaseConnectionPool("Sybase", "syb_server", "user", "pass") class SybaseDatabase(SybaseAugmentation): def myProc(self, myArg): # A one-argument stored procedure... return self.callProc("dbname..my_proc", [myArg]) def gotResults(resultlist): """Callback for handling the result of the procedure""" print `resultlist` db = SybaseDatabase(dbpool) # These will *not* block. Hooray! db.myProc("foo").addCallbacks(gotResults, db.operationError) # Of course, nothing will happen until the reactor is started from twisted.internet import reactor reactor.run() References: [1] http://www.object-craft.com.au/projects/sybase/ Allan -- "If you understand what you're doing, you're not learning anything." -- Anonymous
