Hi hemantsharma,

The minus sign, in workflow-id name identifier, generates the error, due to Javascript syntax restriction.

So, you need to use the escaping syntax [@workflow-id] instead.
And please use the {}, it is better.

	<where>
	<node expr={[@workflow-id] = 123456789} />
	</where>

Hi hemantsharma,

Please see below the limit parameter, and the order clause.

var param = '[@workflow-id] = 123456789';

var query = xtk.queryDef.create(

  <queryDef schema="xtk:workflowLog" operation="select" limit="30">

    <select>

      <node expr="@error"/>

      <node expr="[@workflow-id]"/>

    </select>

    <where>

      <node expr={param} />

    </where>

    <orderBy>

     <node expr="[@workflow-id]" sortDesc="true"/>

    </orderBy>   

  </queryDef>

);

By the way, might you declare as correct answer the post to complete this ticket (green status)?
Many thanks in advance.
