Hi Chris, Thanks, is this code still efficient if the tables relate to 1:1 and you need to show a list of all records in a tabulare table? eg key, NAME, ALIAS, .... where NAME is from database1 and ALIAS is from database2 The code below would impact that for every record in database1, I've to query database2 Is there another way to do this? (more efficient?, ie less database query) Tom. ----- Original Message ----- From: "Chris Gray" <cpgray@library.uwaterloo.ca> To: "Tom Deprez" <tom.deprez@uz.kuleuven.ac.be> Cc: <zope@zope.org> Sent: Monday, December 04, 2000 3:45 PM Subject: Re: [Zope] ZSQLMethods
You want something along these lines:
<dtml-in selectFromTable1> <dtml-in expr="selectFromTable2(id=_['id'])"> ....display record.... </dtml-in> </dtml-in>
This would be more efficient than pulling out the whole of two tables.

Hi,
I'm wondering how the following can be done.
I've 2 databases. I want to do a 'join' with 2 tables, both in a different database. Is it possible to retrieve data of both tables with a ZSQLMethod and then do a programatically join? What's the easiest python way?
Thanks, Tom.
