we're not quoting anything when its bound...what gets returned from
convert_bind_param is what gets sent as a bind param to cursor.execute
(). your custom type class seems fine.
what you should do here first is make a short program using DBAPI
only (which DBAPI are you using ? the three available for MS-SQL
vary widely in their functionality), and try to get the query to work
using a straight cursor.execute(). there could be issues with
comparisons to binary fields or with the DBAPI's ability to bind a
binary field; a call to setinputsizes() may even be needed. once its
determined exactly what your DBAPI needs (or if its possible at
all). any additional data massaging needed on the SQLAlchemy side
can then be addressed.
as a last resort you can inject direct text into a SQL statement
using a string...with ORM it would look like query.filter
("section_OID=0x08C82B7C6A844743") .
