Help - How to sort JavaScript items in an alert Activity

I have a technical workflow that captures fields from the technical workflow and writes them to an alert activity.  The code (below) is working correctly but the output is not sorting by date even through the temporary work table is properly sorted.  Can someone advise the best way to sort the item <%= formatDate(item.CreationDate, "%A %D %B %4Y") %>

 

JS Activity:

var query = xtk.queryDef.create (

<queryDef schema= "temp:query2" operation="select">
<select>
<node expr="CreationDate"/>
<node expr="@appointment"/>
<node expr="Registrations"/>
<node expr="Origin"/>
</select>
</queryDef>)

var itemsXML = query.ExecuteQuery();

vars.itemsXMLString = itemsXML.toXMLString()

 

Alert item: 

<% var itemsXML = new XML(vars.itemsXMLString) for each (var item in itemsXML){ %><% } %>

Creation DateOriginAppointmentRegistrations
<%= formatDate(item.CreationDate, "%A %D %B %4Y") %><%= item.Origin %><%= item.@appointment %><%= item.Registrations %>

 

Current Output:

Creation Date

Origin

Appointment

Registrations

Hi @wpomeroy ,

 

You should write

 

var query = xtk.queryDef.create (

<queryDef schema= "temp:query2" operation="select">
<select>
<node expr="@appointment"/>
<node expr="Registrations"/>
<node expr="Origin"/>
</select>

<orderBy >
<node expr="CreationDate" sortDesc="true"/>
</orderBy >
</queryDef>)

var itemsXML = query.ExecuteQuery();

vars.itemsXMLString = itemsXML.toXMLString();

 

sortDesc="true" will return descending sort

Thanks,

David

Hello @wpomeroy ,

 

You can add sortBy in your query def code.

 

sample code

<orderBy> <node expr="@CreationDate" sortDesc="false"/> </orderBy>

 

Let me know if that helps.

Hello @_manoj_kumar_, I had tried the before without success.  Below is my updated code.  The data flows through the workflow appropriately but then when i attempt to reference the item in the alert activity (<%= formatDate(item.CreationDate, "%A %D %B %4Y") %>) it  appears blank.  Is there a change that needs to be made in the alert activity?

 

var query = xtk.queryDef.create (

<queryDef schema= "temp:query2" operation="select">
<select>
<orderBy >
<node expr="CreationDate" sortDesc="true"/>
</orderBy >
<node expr="@appointment"/>
<node expr="Registrations"/>
<node expr="Origin"/>
</select>
</queryDef>)

var itemsXML = query.ExecuteQuery();

vars.itemsXMLString = itemsXML.toXMLString()

    Thanks @DavidKangni. This worked On a related note, do you know how i would go about only pulling a single instance of an item into an alert output? I am using the standard JS conventions below and then referencing them in the alert.  But since i am using 

    <% var itemsXML = new XML(vars.itemsXMLString) for each (var item in itemsXML) { %> it is pulling in every single row.  Is there any way for a specific node / item to only pull a single row?  Do i need to define that as a seperate variable?

     

    var query = xtk.queryDef.create (

    <queryDef schema= "temp:union" operation="select">
    <select>
    <node expr="CreationDate" />
    <node expr="@appointment"/>
    <node expr="Registrations"/>
    <node expr="Origin"/>
    <node expr="WebRegistrations"/>
    <node expr="ApptSum"/>
    </select>

    <orderBy >
    <node expr="CreationDate" sortDesc="true"/>
    </orderBy >
    </queryDef>)

    var itemsXML = query.ExecuteQuery();

    vars.itemsXMLString = itemsXML.toXMLString()
