ef——存储过程

 

数据库中存在存储过程GetCategory：

ALTER proc [dbo].[GetCategory]
    @cid int
as
begin
    select *
    from Categories
    where @cid = cid
end

执行此存储过程的代码如下：

public IEnumerable<Category> GetCategoryWithProductsWithID(int id)
        {
            var parameter = new SqlParameter
            {
                DbType = DbType.Int32,
                ParameterName = "cid",
                Value = id
            };
            //联表并延迟加载
            var result = (from p in this.Categories.SqlQuery("EXECUTE GetCategory @cid", parameter) select p).ToList();
            return result;
        }     //参数是一一对应的

  例如:

var country = "Australia";
var keyWords = "Beach, Sun";
var destinations = context.Database.SqlQuery<DestinationSummary>("dbo.GetDestinationSummary @p0, @p1", country, keyWords);
