    Hi Devs,

    Is there any way, I can filter FetchXML results by linked entities' attributes?

    See the sample FetchXML below. I want to order the fetched results by mysol_entity2.mysol_orderattribute first then mysol_entity1.orderattribute. I have 4 linked entities in an actual FetchXML and the result should ideally be ordered by one attribute from each linked entity and a main entity.

    <fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false" >
    <entity name="mysol_entity1" >
        <attribute name="mysol_orderattribute" />
        <order attribute="mysol_orderattribute" descending="false" />
        <link-entity name="mysol_entity2" from="mysol_entity2id" to="mysol_entity2" visible="false" link-type="outer" alias="entity2" >
            <attribute name="mysol_orderattribute" />
        </link-entity>
    </entity>
</fetch>

    Best regards,

    Hello,

    I'm not sure that you can do it in FetchXml. Anyway you can sort it after result on your side using Linq.

    Thanks Andrii,

    Yeah, I did it using LINQ, but was looking for a FetchXML way for doing this.

    Just to complete the thread, here is the sample code to sort the FetchXML results on linked entities' attributes using LINQ:

    foreach (var item in result.Entities
	.ThenBy(e => ((AliasedValue)e.Attributes["entity2.mysol_orderattribute"]).Value.ToString())
	.ThenBy(e => e.Attributes["mysol_orderattribute"].ToString()))
{
	string entity2OrderValue = ((AliasedValue)item.Attributes["entity2.mysol_orderattribute"]).Value.ToString();
	string entity1OrderValue = item.Attributes["mysol_orderattribute"].ToString();
	string entityName = item.Attributes["mysol_name"].ToString();

	Console.WriteLine("entity2OrderValue: {0}, entity1OrderValue: {2}, entityName: {3}", entity2OrderValue, entity1OrderValue, entityName);
}
