SELECT UNCOMPRESS(text) FROM with sqlalchemy
===

I store the MySQL Compress function to insert compressed blob data to the database.

In a previous question I was instructed to to use 

    func.compress

( http://stackoverflow.com/questions/10894706/mysql-compress-with-sqlalchemy )

The problem now is that I want to read also the data from the database.
In mysql I would have done

    SELECT UNCOMPRESS(text) FROM ...

probably I should use a getter in the class.
I tried to do somethin like:

    get_html(self):
        return func.uncompress(self.text)

but this does not work. It returns an sqlalchemy.sql.expression.Function and not the string.

Moreover I could not find which functions contains sqlalchemy's func.

Any ideas on how i could write a getter in the object so I get back the uncompressed data.
