It passed my very cursory testing. (Select a Number column, and the resulting type is float.) It looks roughly 20-30% slower than using cx_Oracle without SqlAlchemy (or deactivating the outputtypehandler completely). That compares to about 100% slower for using cdecimal, and 900% for using the stdlib decimal. I'll probably still stick with my hack though. We should definitely head towards using decimal: I don't think the original writers realized they were losing precision, and most of those number fields are going to go away in the redesign. Leaving my hack means that the conversion to decimal will only hit code as I update it. But if there are issues, it's sure nice to have that switch in the patch. -- --Anthony -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
