T is type
YYYY is year
MM is month
DD is day
N is sequencial number
X is check digit
The problem is, how do I generate the sequencial number? since my primary key is not an auto increment integer value, if it was i would use that, but its not.
EDIT can I have the sequencial number resets itself after 1 day (24hours).
P201012080000000001X <-- first
transaction of 2010/12/08
P2010120810000000002X <--- second
transaction of 2010/12/08
P201012090000000001X <--- First

(X is the check digit)

I've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record.
So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing:
Post outsidePost = Post.Find(id); // status of this post is Status.Old using (TransactionScope transaction = new TransactionScope(TransactionMode.New)) { Post p = Post.Find(id); p.Status = Status.New; // new status set here p.Update(); SessionScope.Current.Flush(); transaction.Flush(); transaction.VoteCommit(); } outsidePost.Refresh(); // refresh doesn't get the new status, status is still Status.Old

I am a beginner in ASP.NET using VB Code. I want to generate a Unique reference no by concortinating three column fields.Example:
Column unique reference no (System Generated) - 10 Column with Product Code (User Entry) - APPLE Column with Product Title (User Entry) - FRUITS Unique ref No = FRUITS/APPLE/10
I want to concatenate this three fields to the column Unique Ref No.
Recently, I am working on the website where I am generating random number and storing it in database as the primary key. So, this key would be foreign key for many table, now how would I generate the random number and check if random number does not have duplication? Is there any function to check if number is not duplicate?
I want to generate a unique random number everytime a user submits a form. As the form is submited the data of the form should be placed in a database and a unique random number should be generated so that the user can later use this unique random number to reterieve his details from the database that refer to his unique random id. The unique random number should be atleast 9 digits long.
I am generating a unique Ref number using this sql statement: SELECT REPLACE(STR(CAST(CAST(NEWID() AS binary(5)) AS bigint),12),0,0) as REF Subsequently, I need to insert this REF into sql database table in stored procedure. Here is what I did in my stored procedure:
USE [iBankRecords] GO /****** Object: StoredProcedure [dbo].[stp_addPayee] Script Date: 07/05/2010 21:57:07 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROC [dbo].[stp_addPayee] ( @CUSTID char(10), @PAYEEACCNUM nvarchar(20), @PAYEEACCTYPE char(10) , @PAYEENAME char(20), @PAYERINITIAL char(20), ) AS DECLARE @ReturnValue int INSERT INTO PAYEE (CUSTID, PAYEEACCNUM,PAYEEACCTYPE,PAYEENAME,PAYERINITIAL, REF) VALUES (@CUSTID,@PAYEEACCNUM,@PAYEEACCTYPE,@PAYEENAME,@PAYERINITIAL, REF) IF @@ERROR<>0 BEGIN PRINT 'ERROR' SET @ReturnValue=1 RETURN @RETURNVALUE END ELSE BEGIN SET @ReturnValue=0 RETURN @RETURNVALUE END
May I know how do I have generating a unique ref num and inserting the REF into the above statement?
generating random numbers in texbox and then submit to database. code should check if the generated number already exist in database before submiting to database.
