我不明白为什么这行代码执行时出现语法错误：
return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductGroupDetail_Result>("Kitti_getProductGroupDetail @ProductGroupId", @params);
这是整个方法：
public virtual ObjectResult<Kitti_getProductGroupDetail_Result> Kitti_getProductGroupDetail(Guid ProductGroupId)
{
var @params = new SqlParameter[]
{
new SqlParameter("ProductGroupId", ProductGroupId)
};
return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductGroupDetail_Result>("Kitti_getProductGroupDetail @ProductGroupId", @params);
}
这是调用方法：
public System.Collections.Generic.IEnumerable<ProductDetail> getProductDetailsFromSP(Guid ProductGroupId)
{
System.Collections.Generic.List<ProductDetail> productDetailList = new System.Collections.Generic.List<ProductDetail>();
using (var context = new EFDbContext())
{
var result = context.Kitti_getProductGroupDetail(ProductGroupId);
foreach (Kitti_getProductGroupDetail_Result res in result)
{
ProductDetail productDetail = new ProductDetail();
productDetail.ProductId = res.productid;
productDetail.SizeId = res.sizeid;
productDetail.SizeDescription = res.sizedescription;
productDetail.SizeRank = res.sizerank;
productDetail.ColorId = res.colorid;
productDetail.ColorDescription = res.colordescription;
productDetail.ColorRank = res.colorrank;
productDetail.QuantityRemainingInStock = res.quantityremaininginstock;
productDetail.ProductGroupId = res.productgroupid;
productDetail.ProductGroupName = "ProductGroupName is currently not in the stored procedure or in EF";
productDetail.Description = res.description;
productDetailList.Add(productDetail);
}
}
return productDetailList;
}
结果对象：
public partial class Kitti_getProductGroupDetail_Result
{
public System.Guid productid { get; set; }
public System.Guid productgroupid { get; set; }
public string description { get; set; }
public decimal price { get; set; }
public Nullable<System.Guid> colorid { get; set; }
public string colordescription { get; set; }
public int colorrank { get; set; }
public Nullable<System.Guid> sizeid { get; set; }
public string sizedescription { get; set; }
public int sizerank { get; set; }
public int quantityremaininginstock { get; set; }
public string productname { get; set; }
public string imagesrc { get; set; }
}
最后是我的存储过程：
ALTER PROCEDURE [dbo].[Kitti_getProductGroupDetail]
@ProductGroupId uniqueidentifier
-- Insert statements for procedure here
SELECT product.ProductId as 'productid', product.ProductGroupId as 'productgroupid', product.[Description] as 'description'
, product.Price as 'price', product.ColorId as 'colorid', color.ColorDescription as 'colordescription', color.ColorRank as 'colorrank',
product.SizeId as 'sizeid', size.SizeDescription as 'sizedescription', size.SizeRank as 'sizerank', product.QuantityRemainingInStock as 'quantityremaininginstock',
product.Name as 'productname', product.ProductImageSrc as 'imagesrc'
FROM dbo.Product product
INNER JOIN dbo.Color color
on color.ColorId = product.ColorId
INNER JOIN dbo.Size size
on size.SizeId = product.SizeId
INNER JOIN dbo.ProductGroup productgroup
on productgroup.ProductGroupId = product.ProductGroupId
WHERE product.ProductGroupId = @ProductGroupId
AND product.QuantityRemainingInStock > 0
ProductGroupId肯定会被填充。 EF对我的代码不满意吗？我有一个类似的方法，不需要参数即可执行存储过程-可以正常工作
// this works just fine
public virtual ObjectResult<Kitti_getProductDetailsAndCategory_Result> Kitti_getProductDetailsAndCategory()
{
return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductDetailsAndCategory_Result>("Kitti_getProductDetailsAndCategory");
//ExecuteFunction changed to ExecuteStoreQuery
}
