Autonumber Problem

We have a database which has recently started driving us nuts. It, and
some of its ancestors, have been in use for about 8 years and, until last
January, everything seemed fine. However, in the last couple of months, it
has been sending messages demanding that it be repaired and compacted
several times a week.

This has never happened before.

Recently, we have found that several tables with autonumbers are generating
duplicate values. For example, we have one table with about 20,000
records. It has an autonumber column that sometimes generates the same
number twice. For example, in a couple of instances, 329 has shown up
twice when the next autonumber should be about around 20,000.

Is this autonumber problem known? I have not been able to find references
to it. Is there a quick fix to it such as applying a service pack?

Thanks.

The first thing you should do is backup the database or save it with a
different name.

Did you compact the database? A database should be compacted occasionally,
but AFAIK the database must be failing if it is requesting to be compacted
frequently.

Check the properties in the tables to be sure the Auto number has the proper
settings, Make sure the Index is set to Yes(No duplicates)

I'm finding this to be extremely difficult to set up. I understand that Access won't manage the primary key and the cascade updates for a table. Fine. I tried changing the PK type to number and setting default value to a UDF that manages the auto-numbering. Access won't take a UDF as a default value. Okay, I'll use SQL WITHOUT any aggregate functions, for the default value. Access won't do that either. Okay, I create a second...

Hi all, Here's my situation: I have 2 tables, let's call them TableA and TableB. TableA has a primary key called AffNo, TableB's primary key (--> foreign key in TableA) is called ID, and is Autonumber. I want to do a form to input information for TableA, with a subform for TableB where i can enter several records concerning TableA. This seems to work, however, whenever i click on the 1st Field in the TableB subform, it

If I have a table with an autonumber primary key and 100 records and I delete the last 50 records, the next record added would have a primary key of 101. Is there any way to have the primary key start at 51 after the last 50 records are deleted? Thanks! Traci

Sometimes I use Autonumber fields for ID fields. Furthermore, sometimes I use those same fields in orderdetail type tables. So it's important in that case that once an autonumber key value is assigned to a record that it doesn't change. Occasionally I find that due to corruption or an accidental deletion and restore of a record from a backup the autonumber field needs to be tidied up. So when I create (through AddNew) the autonumber...

1. I want to create an autonumber, my requirement is : 2005/0001 (Year/autonumber), which year & autonumber no. both can auto run. 2. I had create a query by making relation to a table & query, but I can't update record in query or in form. I believe the problem is due to the source query. In source query, there is a filter to show the incomplete record ("is null" in delivery date)], but I need to re-use the job no. if the job is...

A project I'm working on is going to use VB6 as a front end. The back end is going to be pre-existing MS Access 2002 database tables which already have records in them *but do not have any AutoNumber* fields in them. Correct me if I'm wrong, but I'm assuming this means that I cannot now alter these existing Access tables and change their primary key to an "AutoNumber" type. If I'm right about this, I need some suggestions as to the...

Hello, I have a problem with a table in my MS Access 2003 table. The primary key of this table is an autonumber field set to a Long Integer, Yes - no duplicates. The autonumber made it to 10252. Now when I try to add a new record the autonumber started over at 1. Therefore I am getting an error message saying that it can't save this new record because it contains duplicate values. My best guess is that I need to reset the autonumber...

I'm having a problem with a form that uses AutoNumber as the primary key. I have an Abort button to delete the current record and close the form. If AutoNumber is assigned, the code executes a SQL statement that deletes the current record. I need to be able to detect when AutoNumber is unassigned (a new blank record) so that I can simply close the form without running the SQL delete statement. Unfortunately, no tests I can think of...

To comp.databases.ms-access -- I just discovered, to my more than mild dismay, that some tables in my Microsoft Access 2003 database have duplicate numbers in the "AutoNumber" field. (Field Size is set to "Long Integer", and New Values is set to "Increment".) I know that an old version of the Jet database engine can cause this problem, but my version of msjet40.dll is 4.0.8618.0, which is supposedly bug-free in this respect. I am...

Hello, I have created a form that links with a table with the autonumber feature as its primary key. Whenever i create a new record in the form (using a command button ... i have disabled the navigation buttons) it creates a duplicate primary key value. i.e. it always starts back at 30. If i go to the table it is temperamental. Sometimes it will create a new record with the next autonumber in the sequence, and the next time it resets to...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
