How to return unique values from XML Custom Web Publishing...???
I'm using the following call to return email addresses from our database based on buyers of a certain product in our database:
https://server.com/fmi/xml/fmresultset.xml?-db=Invoices&-lay=waGetEmails&-sortfield.1=Leads_Clients::Email_Address&Invoice_Items::Description="&ProductDescription&"&-fi nd
This returns results just fine, however, if the same person bought the same type of item more than once their email is getting returned multiple times.
How can I filter this so that it only returns unique values? Basically, I need the equivalent of a SQL SELECT DISTINCT statement.
Any information would be greatly appreciated. thanks!

you should issue the query to the customers table, not the invoices. this assumes you have a link in between the customers and the invoice_items table, which you may not have

I don't see what that would help...??? The criteria I'm searching on is in Invoice_Items. The data that I'm actually returning is in Leads_Clients (customers). These are related based on an invoice. Invoices::ID relates to Invoice_Items::ID and Leads_Clients::ID relates to Invoices::CustomerID. That's the whole point of a relational database, isn't it? If I have to keep creating relationships everything then I'm confused.
Also, would that even help my problem? If just select from the Invoice_Items with a relationship between the 2, say Leads_Clients::CustomerID and Invoice_Items::CustomerID, I'd still get an email address back for every item in Invoice_Items where there was a match. Which would still be multiple.
You've kinda gotten me all twisted here. I'm a little lost.

I was just trying to find a way to get a single record as the result, and I only see the client table to do this. Ignore my idea if it confuses you. I am always thinking what I would do with a regular FM client, I am not using theses web things as it makes everything more difficult.

I got it to work by creating a recordset and adding each email to it within the parsing loop. Then I can use sorting and only print emails that aren't equal to each other.
