存储过程具有void类型,而不是返回我想要的结果

这是我的存储过程实现:

ALTER procedure [dbo].[ShowProjectByNameOfPerson]
(@name as nvarchar)
as begin

select   Personality.id,COUNT(*) as cnt into  #test 
 from Personality,Project,Personal_project
where Personality.Id = Personal_project.PersonalityId_FK
and Project.Id = Personal_project.ProjectId_FK
and Personality.FullName like N'%'+@name+'%'
group by Personality.Id
order by cnt desc
select * from #test,Personality
where #test.id = Personality.id
end

我在ASP.Net项目中创建了Linq ToSQL类项。我将过程分配给DBML文件。 但是当我想在制作上下文的实例后使用该过程时,我得到了这个错误:

Cannot assign void to an implicitly-typed local variable

No overload for method 'ShowProjectByNameOfPerson' 

这是.cs文件中存储过程的调用代码:

DataClassesDataContext db = new DataClassesDataContext();
var lst = db.ShowProjectByNameOfPerson(txt);

我该如何解决这个问题?

感谢高级。

您对各种t-sql函数类型感到困惑。

你想要的是:

create function [dbo].[ShowProjectByNameOfPerson] (@name as nvarchar)
returns table
as return (
  select
    Personality.Id, Personality.FullName, 
    COUNT(*) as cnt
  from Personality
  inner join Personal_project 
    on Personality.Id = Personal_project.PersonalityId_FK
  where Personality.FullName like N'%' + @name + N'%'
  group by Personality.Id, Personality.FullName
  order by cnt desc
);

请参阅MSDN参考以了解语法变体及其含义: http://msdn.microsoft.com/en-us/library/ms186755.aspx

此外,您应该尽量避免不必要地使用临时表(请参阅我如何更改您的代码)。
