此上下文中不允许列 "dbo"，并且找不到 user-defined 函数或聚合 "dbo.getListOfConference"

Question

我的自定义函数有问题。我希望它返回 table 我的会议用户的姓名。这是代码：

CREATE FUNCTION dbo.getListOfConference(@idConference int)
RETURNS Table
AS
RETURN
SELECT Employee_name FROM dbo.Employee WHERE ID_Employee 
    IN (SELECT ID_Employee FROM dbo.Conference WHERE ID_Conference LIKE @idConference);

消息：

Column "dbo" is not allowed in this context, and the user-defined function or aggregate "dbo.getListOfConference" could not be found.

当我想像这样检查此功能时显示此消息：

PRINT dbo.getListOfConference(254712);

Answer 1

您有一个 table 值函数，但您想将其用作标量函数。没办法。

您可以从中select:

select *
from dbo.getListOfConference(254712);
