Yeah, but I can't make reflection use the TypeDecorator subclass instead of DATETIME can I? I can think of two options: 1. Go through each reflected table and replace each DATETIME type with a TypeDecorator subclass. 2. Find all of the DATETIME columns, and implement a preprocessing step for all of them. So whenever I encounter a DATETIME value, I'd convert it from a string into a Python datetime before passing it into insert/update. I don't necessarily like either of these options as I was hoping to not have my code have to deal with these kinds of typing issues, but I might be out of luck. One other idea though: is there any way to use the compiler extension to do this? For instance, could I add a @compiles function that basically says "if this is a datetime column then do this else do whatever is done by default for columns"? The type compilation capability almost does what I want, except it's for DDL rather than DML. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
