Re: [Zope] how to check if the ResultSet is null?

Hi,

Hi, I stuck on a problem: I am creating a registration form. I need to check if the person info has already in database. I created a Z SQL method which I used "select usr_email from info(table name) where usr_email = <dtml-sqlvar usr_email type=string>" I want to call this method from my dtml method and see if it returns "null". But I'm not sure how to implement this. In Java, it has ResultSet which I can

let's say, you called your ZSQL-method "getThisAddress" then you can do something like this: <dtml-if getThisAddress> You are already in the database </dtml-if> Robert -- Robert Wohlfahrt (robert.wohlfahrt@sachsen-net.com) Tel: 0179 / 2980074 Fax: 0351 / 2880145
