JS to return schema?

Hi guys,

Is it possible to Query a schema, send it to a Javascript to apply a <where> condition and then return the schema result, therefore send it to another flow activity? I have tried it without result.

Here's my js

query = xtk.queryDef.create( 
  <queryDef schema={vars.targetSchema} operation="select" distinct="true" noLineCount="1"> 
    <select>
      <node expr="@field1" alias="field1"/>
    </select>
    <where>
      <condition expr={"@field1='" + localVar + "'"}/>
    </where>
  </queryDef>);
resultSet = query.ExecuteQuery();
return resultSet;
