I’m trying to learn more about system tables of SQL Server. And I get a problem with sysdiagrams. I can’t find which table exists in a particular diagram? its content (diagram’s image) is stored as binary format (column [Definition])

Please give me your opinions
Thanks so much,

I am a Beginner. I have One problem. I want to insert and update records using single stored procedure.

I have One table called Tbl1. It contains three columns such as ExamID, SetUpDate, ExamNumber.

ExamID is an Identity Column.
When I insert the SetUpDate, the ExamNumber will be automatically updated like Oct 2010 01(based on SetUpDate). In that Oct 2010 is the Month and Year of the SetUpDate and 01 is the automatically generated number.

Likewise when i insert another record, the examnumber will be generated as Oct 2010 02 and so on..

Suppose if we select setupdate as Nov 2010. then the exam number will be updated as Nov 2010 01, 02 and so on…

I have write one procedure but it is not working.

Create procedure [dbo].[sp_InsertUpdate]
(
@SetupDate datetime,
@ExamNumber varchar(20)
)

as
begin
insert into OnlineExamHdr
(
SetupDate,
ExamNumber
)
values
(
@SetupDate,
@ExamNumber
)

declare @ExamID int
declare @datept varchar(20)
declare @date varchar(20)
declare @num int

set @date = (select ExamSetupdate from Tbl1 where ExamID = @ExamID)
set @datept = convert(varchar(4), @date,100) + convert(varchar(4),year(@date))
set @num = (select substring(Examnumber, 10, len(Examnumber)) as num from Tbl1 where Examnumber = (select max(Examnumber) from Tbl1 where Examnumber like @datept+’%'))

update Tbl1
set ExamNumber = (select(@datept + space(2) + convert(nvarchar(50), (right(100 + (@num + 1), 2)))))
where ExamID = @ExamID

end

Please anyone give the solution.
