这是我的存储过程，它在sql server中返回两个数据表。但是，当我拖放这个SP在dbml中，它的返回类型变成了int而不是Isingleresult。如何解决这个问题呢。

Answer 1

我以前有过类似的问题。我认为它在SP中有临时表。我不记得我是如何解决它的，但我认为它与使用用户定义的函数而不是存储的proc有关。

是否有没有办法使用Linq-to-Sql而不是SP来实现这一点？

Answer 2

用这种方式声明你的临时表DECLARE @TempTable TABLE而不是CREATE TABLE #tempActualDates，你会很开心。

Answer 3

我有这个问题，以及这是肯定的临时表引起的。我修复它的方法是将

SET FMTONLY OFF; 

添加到存储过程的开始。该解决方案取自this blog，它讨论了实体框架，但似乎也适用于Linq to Sql。
