these are oracle column types that aren't present in the reflected types list. this error is harmless (assuming you don't issue CREATE TABLE like you're doing later). > File > "/home/zope/.buildout/eggs/megrok.rdb-0.10-py2.5.egg/megrok/rdb/setup.py", > line 93, in createTables > metadata.create_all(engine) > NotImplementedError: Can't generate DDL for the null type this is more of a problem. you're reflecting views (and I assume table objects) from your database, and then emitting metadata.create_all() - the views you've reflected are assumed to be tables, which don't exist, and it attempts to issue CREATE TABLE for them, and fails due to the types missing above (but luckily, else it would generate a new table for every view). You shouldn't be calling create_all(). Especially not in a web application when it starts up, thats kind of crazy, and also not when your application receives its table metadata through reflection. > Is there any way to skip/speed up the unrecognized column warnings? what evidence do you have that the warnings themselves are slow ? just because thats what you see actually dumped in your output has no relevance to the work that is actually going on, in this case, the vast majority of columns being reflected that do *not* generate any warning, since you would appear to be reflecting at least 12 views. Reflecting a whole database is not a quick operation. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
