Call nested functions, looping through returned queries

I'm calling a CFC through a RemoteObject call which passes an ID. Within that function I need to call another function based on the ID. That function returns a query which I then loop through to continuously call another function, which also returns a query, which again calls another function...I'm not sure how to get started...


<cfargument name="_ID1" type="numeric" required="yes">
<cfargument name="_ID2" >
<cfargument name="_1stQ" type="query">
	
<cfset _1stQ= getFirstQuery(#_ID1#)>
		
<cfloop query="_1stQ">
<cfset _get2ndQ= getSecondQuery(#_ID2#)>
</cfloop>

you are on the right track! that's exactly how one does this, assuming all the other functions you call are in the same cfc.

just don't forget to VAR-scope all variables you create in your function. i.e. in your above code you will need to add <cfset var _get2ndQ = ""> just after the last <cfargument> tag.

also, no need for those # in function calls.

when you are looping the first query  and getting the second query

<cfset _get2ndQ= getSecondQuery(#_ID2#)>


what is this _ID2  is this you pass as an argument or a column of the query which is returned in first query call.

if an argumen which is passed , so in the loop every time ur passing the same variable.

you will be getting out put same query.

if it is a column of the firstquery and u want to pass dynamically to this call


<cfset _get2ndQ= getSecondQuery(#_ID2#)>

you don't need to actually delcare that in arguments section.

and more over where are you storing this query object which you are getting in the loop.

I agree with srikan.. it seems like some details are needed.

I'm assuming the first ID is passed to the function, but the second ID comes from the first query, otherwise the second query would not make sense.

Here's the same code for that, don't forget you need to scope your variables...

<cffunction name="getData">
  <cfargument name="_ID1" type="numeric" required="yes">
  <!--- removed 1stQ and 2nd ID from arguments because it seems they are not passed in, but are created within the function ----->
  
  <cfset var _1stQ= getFirstQuery(arguments._ID1)> <!---- assuming the ID is passed to the function ---->
  <cfset var _get2ndQ = "">
                
  <cfloop query="_1stQ">
    <cfset _get2ndQ = getSecondQuery(_1stQ.ID)> <!--- assuming the ID comes from the first query ---->
  </cfloop>
 
</cffunction>

Actually, I ended up simply invoking the other methods using a cfinvoke, returning a query, which I then looped and invoked yet another query, and so on... but thanks for all the help!
