The error means that InvoiceTemplateType_Key is a column in both tables, so you have to let the database know which one you actually want. Use your table aliases:
<cfquery name="qgetcreditnotetemplate" datasource="#request.dsn#"> SELECT IT.InvoiceTemplate_FileName, IT.InvoiceTemplateType_Key, I.Invoive_Key FROM InvoiceTemplate IT, INVOICE I WHERE I.IINVOICE_Key = #url.invoice# AND IT.InvoiceTemplateType_Key = 1 </cfquery> Looks like you're not JOINing your tables either, which could be pretty bad in both performance and results, and please be sure you're using CFQUERYPARAM in actual code to screen that URL variable. Something like this (making assumptions here about data types and column references): <cfquery name="qgetcreditnotetemplate" datasource="#request.dsn#"> SELECT IT.InvoiceTemplate_FileName, IT.InvoiceTemplateType_Key, I.Invoive_Key FROM InvoiceTemplate IT INNER JOIN INVOICE I ON IT.InvoiceTemplateType_Key = I.InvoiceTemplateType_Key WHERE I.IINVOICE_Key = <cfqueryparam cfsqltype="CF_SQL_INTEGER" value="#url.invoice#" /> AND IT.InvoiceTemplateType_Key = <cfqueryparam cfsqltype="CF_SQL_INTEGER" value="1" /> </cfquery> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
