Question

你好我的动态查询和我测试过的这个程序正在运行。但是不将数据带到服务器端（实体）

visual studio 2012 框架4.5 实体商店程序

 public IEnumerable<spGetInvoiceDetailSearch_Result> GetInvoiceDetailedSearch(InvoiceModel item)
    {
        return DALContext.GetInvoiceDetailedSearch(item);
    }

首先，调试它非常简单。用打印替换EXEC（@SQLQUery），然后你会看到你的实际查询。

你有一些sintax错误（某些地方，AND在前面错过了一个空格），而且你还有一些被视为字符串的整数。

尝试我的更新程序。

Answer 2

似乎正在调用过程但没有返回任何行，要调试确切的问题，您可以编写实际的硬编码查询，返回1个或多个记录而不是动态查询。所以在这之后有两种可能性

通过edmx进行的过程调用会返回数据，这意味着参数值会导致一些问题。
不会返回任何数据。

要解决任何问题，您需要检查通过Enitity Framework调用SP时生成的相应sql查询。

mssql动态查询实体没有获取值
