sql-server - 是否可以在旨在插入数据的存储过程中插入当前日期时间？

Question

我创建了以下存储过程:

CREATE PROCEDURE dbo.InsertTutees 
    @StudentID INT = NULL, 
    @FirstName VARCHAR(50) = NULL, 
    @Surname   VARCHAR(50) = NULL, 
    @Major     VARCHAR(50) = NULL,
    @Timestamp DATETIME = NULL  
AS 
BEGIN 
    SET NOCOUNT ON 

    INSERT INTO dbo.Tutees (StudentID, FirstName, Surname, Major, Timestamp) 
    VALUES (@StudentID, @FirstName, @Surname, @Major, @Timestamp) 
END 
GO

EXEC dbo.InsertTutees 
         @StudentID = 2, 
         @FirstName = 'Sarah', 
         @Surname = 'Smith', 
         @Major = 'Science',
         @Timestamp = '2013-12-12';

但是我想用当前时间戳替换时间戳值。我试过 GETDATE()，但出现以下错误:

Msg 102, Level 15, State 1, Line 6
Incorrect syntax near ')'

是否有其他方法可以在此 exec 语句中检索当前日期？我应该编辑我的存储过程吗？

感谢您的帮助!

编辑: 这是我尝试完成的 exec 语句:

EXEC dbo.InsertTutees
       @StudentID = 2, 
       @FirstName = 'Sarah' , 
       @Surname = 'Smith' , 
       @Major = 'Science' ,
       @Timestamp = getdate()

Answer 1

你可以使用一个中间变量:

    DECLARE @dt datetime =GETDATE()

    EXEC dbo.InsertTutees
       @StudentID = 2, 
       @FirstName = 'Sarah' , 
       @Surname = 'Smith' , 
       @Major = 'Science' ,
       @Timestamp = @dt
