Add a where element to queryDef through javascript.

[#1]

var query =  <queryDef schema = "temp:enrich32" operation="select">

                             <select>

                                 <node expr="@firstName"/>

                            </select>

                            <where>

                             </where>

                    </queryDef>

var condition =   <condition boolOperator="AND">

                            <condition>

                            <condition boolOperator="OR" internalId="0" expr="@gender = 'M'"/>

                            <condition boolOperator="OR" internalId="1" expr="@gender = 'F'"/>

                           </condition>

I want to add the condition into the where in query in a javascript activity.

Hi,

You can use Javascript JXON then, it's easier. Consider the following workflow:

Activity 1:

var query = {queryDef: {
  schema: "temp:enrich32",
  operation: "select",
  select:{ node: [
    {expr: "@firstName"}
  ]},
  where:{}
}};
vars.query = JSON.stringify(query); // string

Activity 2:

var query = JSON.parse(vars.query); // json
var condition = {
  boolOperator: 'AND',
  condition:[
    {boolOperator: 'OR', internalId: "0", expr: "@gender = 'M'"},
    {boolOperator: "OR", internalId: "1", expr: "@gender = 'F'"},
  ],
};
query.queryDef.where.condition = condition; // add condition to the query

You may use directly query as a JXON (see Using XML ) or convert it with "DOMDocument.fromJXON(query).toXMLString()" which outputs:

<?xml version='1.0'?> 
<queryDef operation="select" schema="temp:enrich32">
     <select>
          <node expr="@firstName"/>
     </select>
     <where>
          <condition boolOperator="AND">
               <condition boolOperator="OR" expr="@gender = 'M'" internalId="0"/>
               <condition boolOperator="OR" expr="@gender = 'F'" internalId="1"/>
          </condition>
     </where>
</queryDef>

Hi,

You can do query.where.appendChild(condition)

See this blog post for more examples

Hi floriancourgey​

I have the condition in the string format which is passed from another javascript activity. when I try to append the conditon to the query , the '<' and '>' symbols in the condition are replaced with '&lt' and '&gt' symbols. Because of this the query is not working. Is there any way to add the condition.

Thanks and Regards
