Applicable Attributes

Any number of annotation attributes (custom XML attributes) may be applied to the RowType element. However, custom attributes may not belong to any XML namespace that is reserved for CSDL. The fully-qualified names for any two custom attributes cannot be the same.

Example

The following example shows a model-defined function that uses a CollectionType element to specify that the function returns a collection of rows (as specified in the RowType element).

<Function Name="LastNamesAfter">
  <Parameter Name="someString" Type="Edm.String" />
  <ReturnType>
   <CollectionType>
     <RowType>
       <Property Name="FirstName" Type="Edm.String" Nullable="false" />
       <Property Name="LastName" Type="Edm.String" Nullable="false" />
     </RowType>
   </CollectionType>
  </ReturnType>
  <DefiningExpression>
            SELECT VALUE ROW(p.FirstName, p.LastName)
            FROM SchoolEntities.People AS p
            WHERE p.LastName &gt;= somestring
  </DefiningExpression>
</Function>
