How to get Top Row Only In A Link-Entity in FetchXML Report?

(0) ShareShare

Posted on by ClixSol 1,505

How can I create a fetchXML query which will retrieve only the top row from a linked-entity?
I have a situation in which I want a report which shows Account and the last Opportunity Closed regarding account, ie in fetchXML i'm trying something like:

<fetch distinct="false" no-lock="false" mapping="logical"><entity name="account" enableprefiltering="1" prefilterparametername="CRM_FilteredAccount"><attribute name="name" alias="name" /><attribute name="customertypecode" alias="customertypecode" /><attribute name="address1_city" alias="address1_city" /><attribute name="industrycode" alias="industrycode" /><attribute name="accountid" /><link-entity name="opportunity" to="accountid" from="parentaccountid" link-type="outer" alias="opportunity1" enableprefiltering="1" prefilterparametername="CRM_FilteredOpportunity"><attribute name="new_partnername" alias="opportunity1_new_partnername" /><attribute name="name" alias="opportunity1_name" /><attribute name="new_microsofttechnologies" alias="opportunity1_new_microsofttechnologies" /><attribute name="createdon" /><attribute name="actualclosedate" alias="opportunity1_actualclosedate" /><order attribute='actualclosedate' descending='true' /><attribute name="opportunityid" /></link-entity></entity></fetch>

    i make it possible by following this article stackoverflow.com/.../auto-numbering-to-parent-and-child-columns

    by indexing on opportunity i display only 1 index opportunity row using Expression.

    it's working as required.

    Thanks.

    Its not possible to apply top (count) record on Linked entity.

    But You can invert your query by putting linked entity as main one . You will then apply your filter to the link entity. I suggest you use Advanced fine to create the query and then download the fetchxml and add the count="5".

    I hope you get my point.

    ClixSol, Sorry I misunderstood before.

    I think <link-entity> doesnt support count for getting top record but there should be some different way to achieve this.

    You can add filter to have this.

    Let me try this using advance find. meanwhile have look on this article.

    But I need Top X from link-entity name="opportunity" . Find below sample code.

    <fetch distinct="false" no-lock="false" mapping="logical">

     <entity name="account" enableprefiltering="1" prefilterparametername="CRM_FilteredAccount">

     <attribute name="name" alias="name" />

     <attribute name="customertypecode" alias="customertypecode" />

     <attribute name="address1_city" alias="address1_city" />

     <attribute name="industrycode" alias="industrycode" />

     <attribute name="accountid" />

    <link-entity name="opportunity" to="accountid" from="parentaccountid" link-type="outer" alias="opportunity1" enableprefiltering="1" prefilterparametername="CRM_FilteredOpportunity">

     <attribute name="new_partnername" alias="opportunity1_new_partnername" />

     <attribute name="name" alias="opportunity1_name" />

     <attribute name="new_microsofttechnologies" alias="opportunity1_new_microsofttechnologies" />

     <attribute name="createdon" />

     <attribute name="actualclosedate" alias="opportunity1_actualclosedate" />

     <order attribute='actualclosedate' descending='true' />

     <attribute name="opportunityid" />

     </link-entity>

    </entity>

    </fetch>

    You need to pass Top X in FetchQuery in count. Find below sample code to fetch top 10 records.

    <fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true" count="10">

     <entity name="account">

       <attribute name="name" />

       <attribute name="primarycontactid" />

       <attribute name="telephone1" />

       <attribute name="accountid" />

       <order attribute="name" descending="false" />

     </entity>

    </fetch>

    How can I create a fetchXML query which will retrieve only the top 1 row from a linked-entity.?

    If you want to use FetchXML in your plugin/Custom Workflow you will need to download the FetchXML from your advanced find.  There is a very helpful button on the advanced find that appears after you have run the advanced find, which you can see below.

    So build the query here with the record you want in your report, and then download FetchXML and use it. 

    here is the link which will help you:
