Subject: Re: [Zope-DB] Using dtml-vars in ZSQL methods?
...
FWIW you
might want to call the query or execute methods directly on the DA
connection object if they are supported.
ZPsycopgDA is my database adapter. I haven't found any documentation of
ZPsycopgDA's methods except its code. In the code, I found a class DB
with a query method (which in turn uses execute and fetchall methods,
whose definitions I can't locate).
I tried to invoke the query method of my adapter (which is named
dhatabase) with this code:
p = context.REQUEST.get('delete_this')
if p:
s = ', '.join([str(x) for x in p])
t = delete from person where person_id in (%s); % s
context.dhatabase.query(query_string=t)
...and got this error: AttributeError: query (full traceback at end of
message). What's wrong with my method call?
I also have a broader question: When one is composing dynamic SQL in Python
scripts, what are the pros and cons of executing them by going directly to
the database adapter (as suggested above) vs passing it in as the sole
argument of an empty ZSQL method? By empty ZQL method I mean something
like:
dtml-comment
title: Query whose whole body is passed in as an argument
connection_id: dhatabase
arguments: foo
/dtml-comment
dtml-var foo
