SUMMARY:
Use the  listToArray(list [, delimiters ])  function.

SHORT EXAMPLE:
<cfset queryAddColumn(myQuery,"fav_pokemon",listToArray("Pikachu,Bulbasaur,Venomoth,Dewgong,Snorlax"))>

— LONG EXAMPLE: —
<!— create a query which has a "title" column,
    but lacks a "notes" column: —>
    <cfset Q = queryNew('title')>
<!— stock the query with two rows,
    regarding apples and oranges: —>
    <cfset queryAddRow(Q)><!— first row —>
    <cfset querySetCell(Q,"title","Apples")>
    <cfset queryAddRow(Q)><!— second row —>
    <cfset querySetCell(Q,"title","Oranges")>
<!— NOW, ADD A NEW COLUMN called "notes",
    FROM AN INLINE ARRAY containing values —>
    <cfset queryAddColumn(Q,"notes",listToArray("Apples are great , Unless compared to oranges"))>
<!— see if it worked: —>
<cfdump var="#Q#">
— :LONG EXAMPLE —

Hope that helps!

For me personally, I’m using it as follows for loading static data into arrays.

<script>
aSet=arraynew(2);
i=0;
i++; aSet[i]=[ “Illinois”, “IL”, 21, “Mississippi River; 279 feet, 33rd” ];
i++; aSet[i]=[ “California”, “CA”, 31, “DeathValley; 282 feet below sea level, 1st” ];

// and so on….
</script>

There are some glaring deficiencies with this feature, but I’m glad they finally put it in and hopeful they improve on it in the future.

<cfset test = arrayNew(1)>
<cfset test[1] = “foo”>
<cfset test[arrayLen(test)] = {name=”Dan”,age=27,state=”VA”}>
<cfdump var=”#test#”>

That works. So, the issue is the evaluation of the arrayLen() +1 in there.

Also, why would you use:

When you can ArrayAppend()?

Also, your test above isn’t accurate. Array index in CF -starts- at zero. Your code is telling it to bypass zero and set 1…?

<cfset test = arrayNew(1)>
<cfset test[arrayLen(test)+1] = {name=”Dan”,age=27,state=”VA”}>

*boom…. error*

This would be awesome but doesn’t work:

<cfset test = [{name=”Dan”,age=30,state=”VA”},
{name=”Chris”,age=23,state=”DC”},
{name=”Todd”,age=53,state=”MA”}]>

Instead you have to either expressly set the array indexes:

<cfset test = arrayNew(1)>
<cfset test[1] = {name=”Dan”,age=30,state=”VA”}>
*repeated for 2 and 3

or use a temporary variable:

<cfset test = arrayNew(1)>
<cfset tmp = {name=”Dan”,age=30,state=”VA”}>
<cfset arrayAppend(test,tmp)>
* repeated two more times

Rob,

The array is an argument for another function which does not perform an action on that array. It uses the array as a source of values to add a new column to a query variable.

I think Adobe will make this available in the future.
