EntitySet Element (SSDL)

An EntitySet element in store schema definition language (SSDL) represents a table or view in the underlying database. An EntityType element in SSDL represents a row in the table or view. The EntityType attribute of an EntitySet element specifies the particular SSDL entity type that represents rows in an SSDL entity set. The mapping between a CSDL entity set and an SSDL entity set is specified in an EntitySetMapping element.

The EntitySet element can have the following child elements (in the order listed):

Applicable Attributes

The following table describes the attributes that can be applied to the EntitySet element.

Some attributes (not listed here) may be qualified with the store alias, which is the alias for the http://schemas.microsoft.com/ado/2007/12/edm/EntityStoreSchemaGenerator namespace. These attributes are used by the Update Model Wizard when updating a model.

Attribute Name Is Required Value

Bb387152.note(en-us,VS.100).gifNote:
Any number of annotation attributes (custom XML attributes) may be applied to the EntitySet element. However, custom attributes may not belong to any XML namespace that is reserved for SSDL. The fully-qualified names for any two custom attributes cannot be the same.

Example

The following example shows an EntityContainer element that has two EntitySet elements and one AssociationSet element:

<EntityContainer Name="ExampleModelStoreContainer">
  <EntitySet Name="Customers" 
             EntityType="ExampleModel.Store.Customers" 
             Schema="dbo" />
  <EntitySet Name="Orders" 
             EntityType="ExampleModel.Store.Orders" 
             Schema="dbo" />
  <AssociationSet Name="FK_CustomerOrders" 
                  Association="ExampleModel.Store.FK_CustomerOrders">
    <End Role="Customers" EntitySet="Customers" />
    <End Role="Orders" EntitySet="Orders" />
  </AssociationSet>
</EntityContainer>
