Displaying query values horizontally

Question

I have a subreport with a query that returns a single field.
WHat I'd like to do is display it as a list on one line, as opposed
to showing each item on its own line. I couldn't find a
straightforward way to do this, so I tried to come up with a hack
but it's not working too well. What I did was simply output one
field with ValueList(query.FieldName, ", ") and then set the Print
When on the band to query.CurrentRow EQ 1 . Unfortunately the
ValueList() function doesn't seem to be working properly for this.
I tried setting the query to advanced and specifying a query name,
then using that query name in the function and that doesn't work
either. Anybody has any idea how to get ValueList() working or how
to solve my particular problem?

Answer 1

I came up with a solution for this, here it is for the
benefit of others. Basicaly, I created a report function that would
build the list for me. The function is as follows:
<cffunction name="outputAsList">
<cfargument name="qData" />
<cfargument name="col" />
<cfset list = "" />
<cfloop from="1" to="#qData.recordcount#" index="i">
<cfif i GT 1>
<cfset list = list & ", " />
</cfif>
<cfset list = list & qData[arguments.col]
/>
</cfloop>
<cfreturn list />
</cffunction>
Then I set Print When on the subreport band to
query.CurrentRow EQ 1 so that the list would only get output once.
Then in the field I put the following expression:
report.outputAsList(query, "MyColName")
Works fine. Yet another hack, of course, but that's the way I
managed to get what I needed, since ValueList just won't play
nice.
