Us Coldfusion ArcIMS folks have grown to love and hate the Out_Querytable variable. For those of you that don't know what Out_Querytable is, its a query object that gets returned from Coldfusion after you send a query (spatial or attribute) to ArcIMS. This is very handy to have - becasue Coldfusion works so well with these types of objects. For you windows based folks, its essentially the same as a recordset.
The good: You can loop over them, display them, make a nice value list, query them (with coldfusion's ability to query an existing query object). Basically anything that you can do to a coldfusion query object, you can do to the Out_Querytable variable.
The bad: Things tend to get a bit hairy when you use ArcSDE based data. Who uses shapefiles these days anyway...The biggest issue for me are column names that get returned. For example, lets say I query roads. The columns that get returned will be fully qualified - like DBName.Owner.Tablename (in the case of SQl Server). Now try making a nice valuelist with VALUELIST(Out_QueryTable.DBName.Owner.Tablename) and see what evil things happen. Luckily, a few years back, James Welch (where are ya these days James?) created a sweet custom tag called cf_ArcSDEquery, which essentially converts the query to wddx, fixes it, at converts it back to a query object. The tag used to be on ArcScripts, but I haven't seen it there in quite some time. So, I'll attach it for everyone if they don't already use it.
I also do lots of multiple spatial queries right after each other - like in a drill down identify. The problem is that lets say I find a result in the first, but not the second, and then the 3rd returns a result. If, after each query, I test to see IsDefined("Out_QueryTable") then run some processing...Its going to bomb after the 2nd spatial query - becasue it does exist - but not from that query. Of course, you can rename your queries and do all sorts of crazy work arounds to compensate for this. However, I recently discovered a fantastic undocumented function - removeRows:
Queryname.removeRows(startrow,endrow)So, this means now that I can perform a spatial query, test for the results, do something with the results, and then remove the rows from the Out_querytable object. Then, I can move on to the next operation...Something like this:
<cfoutput>
<cf_arcims action="Request"
servicename="#mapservicename#"
servername="#mapservername#"
serverport="#mapserverport#"
GenerateHTML="false"
ParseResponseAXL="true"
CustomService="Query"

<SPATIALQUERY searchorder="attributefirst" where="objectid IN (#featureID#)">
<BUFFER distance="0" bufferunits="FEET" >
<TARGETLAYER id="#SOILSLayerID#" />
</BUFFER>
</SPATIALQUERY>
</GET_FEATURES>
</REQUEST>
</ARCXML>
</cf_arcims>
</cfoutput>
<cfif Out_QueryTable.recordcount GT 0>
<cf_ArcSDEquery query="OUT_QueryTable" output="Out_QueryTable">
<cfset SRCSOILSValueslist = quotedvaluelist(Out_QueryTable.ObjectID)>
<CFQUERY NAME="SOILSResults" DATASOURCE="#dsn#">
SELECT MUName
FROM SRCSOILS
WHERE ObjectID in (#PreserveSingleQuotes(SOILSValueslist)#)
</CFQUERY>
</cfif>
<!--- Use this function to delete all the rows from the query --->
<cfset temp = OUT_QueryTable.removeRows(0,OUT_QueryTable.recordcount)>
Then I can do the next drill down spatial query....Hope that makes sense and or helps someone out. Don't forget, here is the code for the cf_ArcSDEquery which will makle your life sooo much easier when working with SDE data:
<cfsetting enablecfoutputonly="yes">
<cfparam name="attributes.output" default="NewQry">
<cfif not isDefined("caller.#attributes.query#")>
<cfoutput>ArcSDEquery - #attributes.query# is not a valid Query and cannot be returned as #attributes.output#</cfoutput>
<cfabort>
</cfif>
<cfif FindNoCase("OBJECTID", evaluate("caller.#attributes.query#.columnlist"))>
<!--- arcsde --->
<cfset oldCols = Evaluate("caller.#attributes.query#.columnlist")>
<!--- setup new col names --->
<cfset aGoodCols = "">
<cfloop index="c" list="#oldCols#">
<cfset aGoodCols = ListAppend(aGoodCols, ListGetAt(c,ListLen(c,"."),"."))>
<cfif FindNoCase("ObjectID",c)>
<cfset caller.objectid = "#c#">
</cfif>
</cfloop>
<!--- convert to WDDX Packet --->
<cfwddx action="CFML2WDDX" input="#Evaluate("caller.#attributes.query#")#" output="OrigQryWDDX">
<!--- replace invalid names in fieldNames list --->
<cfset goodColWDDX = OrigQryWDDX>
<cfloop index="col" from="1" to="#ListLen(oldCols)#">
<cfset goodColWDDX = ReplaceNoCase(goodColWDDX, "#ListGetAt(oldCols,col)#", "#ListGetAt(aGoodCols,col)#", "all")>
</cfloop>
<!--- Turn the packet back into a query --->
<cfwddx action="WDDX2CFML" input="#goodColWDDX#" output="NewQry">
<cfelse>
<!--- not arcsde --->
<cfset NewQry = Evaluate("caller.#attributes.query#")>

Rio Ferdinand: honor more important than money
Manchester united defender Rio Ferdinand firmly said, his career should be taken by his honor to judge, not how much money he earned. Just last week spent 34 years old of birthday, he said he has achieved in front of the honor of (5 times the premiership champions and a champions league), he has to earn money fundamental isn't worth mentioning.
