The code is still failing many of the unit tests but these appear to be cascading errors rather than independent ones. Also, the initial failure is frequently a problem with a tear-down trying to drop a database object that still has referential integrity constraints. -- Ticket URL: <http://www.sqlalchemy.org/trac/ticket/785#comment:8> sqlalchemy <http://www.sqlalchemy.org/> The Database Toolkit for Python |

#785: add sybase support ----------------------------+----------------------------------------------- Reporter: guest | Owner: phrrngtn Type: enhancement | Status: new Priority: medium | Milestone: 0.5.xx Component: engine | Severity: very major - up to 2 days Resolution: | Keywords: sybase Status_field: in progress | ----------------------------+----------------------------------------------- Changes (by phrrngtn): * owner: any volunteer => phrrngtn * status_field: needs a volunteer => in progress Comment: I have done a bunch of work on the Python-sybase module ( http://python- sybase.sourceforge.net). Initial progress was very slow as I did not have adequate diagnostics/debugging set up. However, after some ugly hacking (which should be removed before merging this code into the tree!), the dialect passes quite a few of the unit-tests. The changes were: . get sybase ct-lib diagnostics forwarded to the standard logging framework . add positional parameter support to the python-sybase driver . guard against unicode strings being used for named parameters (not sure what the level of unicode support is in Python-sybase nor in ct-lib itself) . wrap server-message callbacks as logging invocations (this is until such time as we figure out which ones should be thrown as exceptions) . get introspection working (kinda sorta) A lot of work remains but hopefully on 'higher-level' stuff like getting all the unit-tests to work, adding pyodbc support. -- Ticket URL: <http://www.sqlalchemy.org/trac/ticket/785#comment:9> sqlalchemy <http://www.sqlalchemy.org/> The Database Toolkit for Python |

You're probably going to want to look at the 0.6 branch because it changes how we structure dialects and the dbapis that they use. -- Ticket URL: <http://www.sqlalchemy.org/trac/ticket/785#comment:10> sqlalchemy <http://www.sqlalchemy.org/> The Database Toolkit for Python |

For the moment, we are getting by with the mssql dialect against Sybase (via pyodbc + FreeTDS) as all current applications are read-only. pjjH -- Ticket URL: <http://www.sqlalchemy.org/trac/ticket/785#comment:11> sqlalchemy <http://www.sqlalchemy.org/> The Database Toolkit for Python |
