CRM QueryExpression with Link to Same Table / Entity - dynamics-crm

Question

I am trying to perform the following SQL equivalent query within CRM using a QueryExpression and LinkEntity. Any ideas? I am fairly stumped. I have used the LinkEntity before but not sure how to reference or alias the same entity type.
select t1.UoMId, t1.BaseUoM, t1.UoMScheduleId, t1.Name, t1.Quantity
from UoMBase t1
inner join UoMBase t2 on t1.UoMScheduleId = t2.UoMScheduleId
where t2.UoMId = '57E59AB7-AC8F-E511-80F0-005056BE36DF';
Which will result in the following entity records:

Answer 1

Try to convert following to QueryExpression:
<fetch mapping="logical" version="1.0">
<entity name="UoM">
<attribute name="UoMId" />
<attribute name="BaseUoM" />
<attribute name="UoMScheduleId" />
<attribute name="Name" />
<attribute name="Quantity" />
<link-entity name="UoM" from="UoMScheduleId" to="UoMScheduleId" alias="t2" link-type="inner">
<filter>
<condition attribute="UoMId" operator="eq" value="57E59AB7-AC8F-E511-80F0-005056BE36DF" />
</filter>
</link-entity>
</entity>
</fetch>
QueryExpression query = new QueryExpression("uom");
query.ColumnSet = new ColumnSet(new[] { "uomid", "baseuom", "uomscheduleid", "name", "quantity", });
query.LinkEntities.Add(new LinkEntity("uom", "uom", "uomscheduleid", "uomscheduleid", JoinOperator.Inner) { EntityAlias = "t2" });
query.Criteria.AddCondition("t2", "uomid", ConditionOperator.Equal, guidID);
EntityCollection result = OrganizationService.RetrieveMultiple(query);
