Okay here's what I'm trying to do.

I have a table with the columns

customer_id product_purchased

When I query it comes out like:

1 product1
1 product2
1 product4
2 product3
2 product4
3 product3
3 product2

What I want is:
1 product1, product2, product4
2 product3, product4
3 product3, product2

Any thoughts?  I've been trying this via SQL and Coldfusion, but I'm stumped after 2 days.

If you want commas in between, you'd need to adjust gdemaria's example slightly. One way is:

<cfoutput query="qry" group="customer_id">
  #customer_id# 
  <cfoutput>
       <cfif currentRow gt 1 and qry.customer_id[currentRow] eq qry.customer_id[currentRow-1]>,</cfif>
      #product_purchased#
  </cfoutput>
  <br>
</cfoutput> 

Open in new window


You could also do it in SQL with XML PATH. But using CF is the simplest

Thank you both!  I had gone down the SQL path and was way over complicating the issue.
