 ## Limitations
 
 Dataverse column comparison has the following limitations:
 
-- You can only compare columns within a single table.
-- Only two columns may be compared at a time.
+- With Web API and [QueryExpression](xref:Microsoft.Xrm.Sdk.Query.QueryExpression), and you can only compare columns within a single table.
+
+   With FetchXml, you can compare columns in other related tables. See [Cross table comparisons](#cross-table-comparisons).

+- Only two columns can be compared at a time.
 - Multi-value condition operators aren't supported (that is, "in").
 - Extended condition operators aren't supported (that is, "creditlimit \> spends+1000").
 - Incompatible column comparison isn't supported. For example, "int vs. int" columns is a valid comparison but "int vs. string" columns isn't a valid comparison.
@@ -59,6 +60,27 @@ The following example shows how to compare columns using FetchXML.
 For FetchXML, the `valueof` attribute the condition element specifies the name of the column to compare with the selected column. In the previous example, the `firstname` column is being compared against the `lastname` column and returns any records that contain
 the same value across both columns.
 
+## Cross table comparisons
+
+With FetchXML only, you can compare field values in related tables. The following example returns rows where the contact `fullname` column matches the account `name` column.
+
+```xml
+<fetch> 
+  <entity name='contact'>
+    <attribute name='contactid' />
+    <attribute name='fullname' />
+    <filter type='and'>
+      <condition attribute='fullname' operator='eq' valueof='acct.name' />
+    </filter>
+    <link-entity name='account' from='accountid' to='parentcustomerid' link-type='outer' alias='acct'>
+      <attribute name='name' />
+    </link-entity>
+  </entity>
+</fetch>
+```
+
+The `link-entity` element must use an `alias` attribute and the value of the `valueof` parameter must reference that alias and the column name in the related table.
