Body
The query would need to be present in both cases as the query will not be remembered from one request to another... In the following example the query may not have been created when the second request is made. <pre><code><cfif StructKeyExists(form, "submit")>  <cfquery datasource="#session.HousingDataSource#" name="query"> ... </cfquery> </cfif> <cfif StructKeyExists(form, "export")>  <cfset output = QueryToCSV(query, "studentFirst,studentLast,studentNumber,Detail1,itemDate")/> <cffile action="write" file="#filename#" output="#output#"/> </cfif> </code></pre> If you update the code as follows then when you export it will run the query again to export it... <pre><code><cfif StructKeyExists(form, "submit") || StructKeyExists(form, "export")>  <cfquery datasource="#session.HousingDataSource#" name="query"> ... </cfquery> </cfif> <cfif StructKeyExists(form, "export")> <cfset output = QueryToCSV(query, "studentFirst,studentLast,studentNumber,Detail1,itemDate")/> <cffile action="write" file="#filename#" output="#output#"/> </cfif> </code></pre> Or you can save it in the session... <pre><code><cfif StructKeyExists(form, "submit")> <cfquery datasource="#session.HousingDataSource#" name="query"> ... </cfquery> <cfset session.query = query/> </cfif> <cfif StructKeyExists(form, "export") && StructKeyExists(session, "query")> <cfset output = QueryToCSV(session.query, "studentFirst,studentLast,studentNumber,Detail1,itemDate")/> <cffile action="write" file="#filename#" output="#output#"/> </cfif> </code></pre> Or the application scope.

Querying!

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
