Question

Assume I have this domain object...

public class SpansMultipleTables
{
     public int CommonID {get; set;}

     public string Table1Value {get; set;}

             


        

Answer 1

Try Join, but I would recommend changing your design.

public class SpansMultipleTablesMap : ClassMap
{
  public SpansMultipleTablesMap()
  {
    Id(x => x.CommonID);
    Join("Table1", m =>
    {
      m.Map(x => x.Table1Value, "Value");
    });
    Join("Table2", m =>
    {
      m.Map(x => x.Table2Value, "Value");
    });
    Join("Table3", m =>
    {
      m.Map(x => x.Table3Value, "Value");
    });
  }
}
