Examples

The following example compiles and then invokes a query that accepts DateTime and Decimal input parameters and returns a sequence of orders where the order date is later than March 8, 2003 and the total due is less than $300.00:

static readonly Func<AdventureWorksEntities, DateTime, Decimal, IQueryable<SalesOrderHeader>> s_compiledQuery5 = 
    CompiledQuery.Compile<AdventureWorksEntities, DateTime, Decimal, IQueryable<SalesOrderHeader>>(
            (ctx, orderDate, totalDue) => from product in ctx.SalesOrderHeaders
                                          where product.OrderDate > orderDate 
                                             && product.TotalDue < totalDue
                                          orderby product.OrderDate
                                          select product);

static void CompiledQuery5()
{            
    using (AdventureWorksEntities context = new AdventureWorksEntities())
    {         
        DateTime date = new DateTime(2003, 3, 8);
        Decimal amountDue = 300.00M;

        IQueryable<SalesOrderHeader> orders = s_compiledQuery5.Invoke(context, date, amountDue);

        foreach (SalesOrderHeader order in orders)
        {
            Console.WriteLine("ID: {0} Order date: {1} Total due: {2}", order.SalesOrderID, order.OrderDate, order.TotalDue);
        }
    }            
}
ReadOnly s_compQuery5 = _
   CompiledQuery.Compile(Of AdventureWorksEntities, DateTime, Decimal, IQueryable(Of SalesOrderHeader))( _
                Function(ctx, orderDate, totalDue) From product In ctx.SalesOrderHeaders _
                                                   Where product.OrderDate > orderDate _

                                                   Order By product.OrderDate _
                                                   Select product)
Sub CompiledQuery5()

    Using context As New AdventureWorksEntities()

        Dim orderedAfterDate As DateTime = New DateTime(2003, 3, 8)
        Dim amountDue As Decimal = 300.0

        Dim orders As IQueryable(Of SalesOrderHeader) = _
            s_compQuery5.Invoke(context, orderedAfterDate, amountDue)

        For Each order In orders
            Console.WriteLine("ID: {0} Order date: {1} Total due: {2}", _
                              order.SalesOrderID, order.OrderDate, order.TotalDue)
        Next

    End Using
End Sub

Remarks

Provides for compilation and caching of queries for reuse. Conceptually this class contains a single Compile method with several overloads. You call the Compile method to create a new delegate to represent the compiled query. The delegate, when invoked with the ObjectContext input parameter and other parameter values, produces some result (such as an IQueryable<T> instance). The query is translated and cached when the delegate is invoked for the first time.
