SQL Server 2008 R2中的存储过程调用错误

Question

我在我的SQL Server中有一个存储过程,它以这些行代码开头:

CREATE PROCEDURE [dbo].[SP_Notify]
-- Add the parameters for the stored procedure here
@UserName nvarchar(50),
@lastDate datetime
AS
BEGIN

-- my code...

我尝试使用以下代码调用存储过程:

DECLARE @data datetime
DECLARE @Username nvarchar(50)
SET @Username = CAST('myUserName' AS nvarchar(50))
SET @data = GetDate()
SP_Notify @Username , @data

但这会导致此错误:

消息102,级别15,状态1,行
10'SP_Notify'附近的语法错误.

Answer 1

您需要EXEC在存储过程调用之前添加:

DECLARE @data datetime
DECLARE @Username nvarchar(50)
SET @Username = CAST('myUserName' AS nvarchar(50))
SET @data = GetDate()
EXEC SP_Notify @Username , @data

Answer 2

尝试:

DECLARE @data datetime
DECLARE @Username nvarchar(50)
SET @Username = CAST('myUserName' AS nvarchar(50))
SET @data = GetDate()

EXEC SP_Notify @Username = @Username, @lastDate = @data

我添加了EXEC并指定了参数值,而不是依赖于序号位置来传递它们(这可能会回来咬你,否则,如果你将来修改SP,重新排序和/或添加参数).
