Question

我有一个程序，我试图显示每个主题的每个人的出勤率。问题是我正在使用旋转来完成所需的工作。我面临的问题是本地主机上的程序在本地数据库上工作正常，但在服务器上我收到此错误：

超时已过期。操作完成之前经过的超时时间或服务器没有响应。

我的程序如下：

ALTER PROCEDURE [dbo].[prStudentLoadFullAttendance]  
    @SemID int ,
    @CourseID int
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    Declare @S  nvarchar(1024)
 Declare @Q nvarchar(Max)


set @S=''
