Question

我正在预订＆amp;在ASP.NET MVC5中开具发票的Web应用程序。在我的预订索引页面（应用程序的主页面）上，我有一个搜索表单和一个显示PagedList内容的表。

目前预订表中有大约100.000条记录。他们中的大多数都有一个状态为DONE的发票。大多数查询适用于没有发票的预订或状态为PENDING的ivoice。加载索引页大约需要8秒。（空过滤器=＆gt;查询所有预订）这太长了......

大部分时间都花在从数据库中提取数据上。有什么方法可以加快查询速度？

public IQueryable<Booking> GetByFilter(SearchBookingViewModel model)
{
    var bookings = _context.Bookings.Include(b => b.Invoice).Include(b => b.Customer).Include(b => b.Origin).Include(b => b.Destination);
    if (!model.IncludeInvoiced)
    {
        bookings = bookings.Where(b => b.InvoiceID == null || b.Invoice.Status == InvoiceStatus.PENDING);
    }
    if (!string.IsNullOrWhiteSpace(model.Awb))
    {
        bookings = bookings.Where(b => b.Awb.ToUpper().Contains(model.Awb.ToUpper()));
    }
    if (!string.IsNullOrWhiteSpace(model.ClientRef))
    {
        bookings = bookings.Where(b => b.ClientRef.ToUpper().Contains(model.ClientRef.ToUpper()));
    }
    if (!string.IsNullOrWhiteSpace(model.CustomerCode))
    {
        bookings = bookings.Where(b => b.Customer.CustomerCode == model.CustomerCode);
    }
    if (!string.IsNullOrWhiteSpace(model.OriginCode))
    {
        bookings = bookings.Where(b => b.Origin.AirportCode == model.OriginCode);
    }
    if (!string.IsNullOrWhiteSpace(model.DestinationCode))
    {
        bookings = bookings.Where(b => b.Destination.AirportCode == model.DestinationCode);
    }
    if (model.FromDate.HasValue)
    {
        bookings = bookings.Where(b => b.BookingDate >= model.FromDate);
    }
    if (model.ToDate.HasValue)
    {
        bookings = bookings.Where(b => b.BookingDate <= model.ToDate);
    }

    return bookings.OrderByDescending(b => b.BookingID);
}

售票：

public class Booking
{    
    public int BookingID { get; set; }
    public int? InvoiceID { get; set; }
    public int CustomerID { get; set; }  
    public int OriginID { get; set; }    
    public int DestinationID { get; set; }
    public BookingType BookingType { get; set; }
    public string Awb { get; set; }
    public string ClientRef { get; set; }
    public DateTime BookingDate { get; set; }
    public int NumberOfPieces { get; set; }
    public int GrossWeight { get; set; }
    public int? VolumetricWeight { get; set; }
    public decimal? Rate { get; set; }
    public decimal TotalCharges { get; set; }
    public string Info { get; set; }    
    public string Location { get; set; }

    // Navigation
    public virtual Airport Origin { get; set; }
    public virtual Airport Destination { get; set; }
    public virtual ICollection<BookingDetail> BookingDetails { get; set; }

    public virtual Customer Customer { get; set; }
    public virtual Invoice Invoice { get; set; }
    public virtual Pod Pod { get; set; }
}

控制器：

public ActionResult Search(Filter filter)
{
    filter.Bookings = _db.Bookings.GetByFilter(filter).ToPagedList(filter.Page, filter.NumberPerPage);

    return PartialView("_SearchResultsPartial", filter);
}

ToPagedList执行.Count（）+ .Skip（）。在IQueryable上执行（）

ASP.NET MVC加速查询较大的表
