Om meerdere rasters in één query op te halen, wordt de QueryMultiple methode gebruikt. Hiermee kunt u elk raster achtereenvolgens ophalen via opeenvolgende oproepen tegen de geretourneerde GridReader .

var sql = @"select * from Customers where CustomerId = @id
            select * from Orders where CustomerId = @id
            select * from Returns where CustomerId = @id";

using (var multi = connection.QueryMultiple(sql, new {id=selectedId}))
{
   var customer = multi.Read<Customer>().Single();
   var orders = multi.Read<Order>().ToList();
   var returns = multi.Read<Return>().ToList();
}
