Hello,
Any idea with the following query :
Session.query(Folder, Data).
select_from(folder.join(content).outerjoin(data.select().alias('foo')))
why SQLAlchemy generates :
SELECT ...
FROM data, folder JOIN content ON content.id = folder.content_id LEFT
OUTER JOIN (SELECT data.content_id AS content_id, data.mime_id AS
mime_id, data.file_size AS file_size, data.name AS name
FROM data) AS foo ON content.id = foo.content_id
instead of
SELECT ...
FROM folder JOIN content ON content.id = folder.content_id LEFT OUTER
JOIN (SELECT data.content_id AS content_id, data.mime_id AS mime_id,
data.file_size AS file_size, data.name AS name
FROM data) AS foo ON content.id = foo.content_id
Is there a way to tell SQLAlchemy that it should map "Data" with the
result from the subquery (foo) instead of adding the table in the FROM ?
Thanks,
Julien
