Обсуждение: Use of .mogrify

Hi All,

I just stumbled across this conversation:
http://permalink.gmane.org/gmane.comp.python.db.psycopg.devel/4775

Is .mogrify still just for debugging usage?

I have a query generated by Django's ORM that I would like to execute as
plain SQL (because I will wrap some SQL around it).

Cheers,
Tobias

Any reason you cannot just put it into execute()?

That message is still valid: currently mogrify does what you expect
(actually better than it used to do in 2008). But in the future we
don't guarantee that (actually, if we move to sending parameters to
the server, new cursor classes may not have a mogrify method at all).

Why don't you wrap the SQL around the query with placeholders and then
pass the parameters?
