Hi,
This is really weird... I have a database that has an autonumber field.
Records 1-70 were deleted. Various things have changed to the front end and
a few extra fields added to the table.
Now Access has decided to re-use 1-70 again!!! however this went unnoticed
until it tried to have 2 x 71's !!
Has anyone had this before / know a reason / know a workaround??
Thanks, Jon

Is the Allow Duplicates property for the field set to On?

I had this happen for no apparent reason a few months ago. The
autonumber skipped some numbers, then went back and used the lower
numbers and generated errors when it reached the higher number and
tried to use it twice.
I had not deleted a batch of records, however I do delete records one
at a time fairly often to correct user entry mistakes.
I fixed this by copying the table, deleting and re-inserting the
autonumber ID field, and re-naming the table to the same name as
before. I don't use the autonumber field for anything, it's only for
the database to use internally, so this didn't cause me any problems
with links or othe number applications.
Another approach might be to copy the table into Excel, fix the
numbers, then copy it back into the table.

As far as I know it's just random corruption. It happened just before
I implemented a front-end back-end split, and one of the reasons I did
the split was to help prevent corruption. Before the split we had
corrupted records or fields every few weeks, and this was the third
corruption problem that surfaced while I was working on the split.
We haven't had nearly as much corruption since the split, in fact, I
can't remember having any. The split also prevented that annoying
"form has been changed" message when all users were in the same forms.

Is there a way to reset the AutoNumber sequence?
I have several tables that use the AutoNumber field as the Primary Key, and
I'd like to somehow do an Import/Export that will make remove the breaks in
the sequence. A few breaks in sequence is not a big deal, but I have one
table with under 200 records, but the last AutoNumber PK ID field is over
1500 - due to a lot of edits....

Hi,
Hope someone can help. Here's the scenario:
I have two MSAccess tables MainTab and SubTab. MainTab has an autonumber
'id' column as primary key. Subtab has this id column as a foreign key.
There is a one-to-many relationship defined on MainTab and Subtab using the
id column. The join type is include all from MainTab and only rows with
matching value from SubTab. Referential integrity enforced; cascading

I have a table where the key field is an autonumber. The highest number
was about 900, and there are several gaps in the sequence. This database was
recently converted from Access 97 to Access 2002/XP
At some point, it started using low numbers for new records. I compacted the
database, and it's still doing this.
Is this a problem? Will it start overwriting the high numbers when it gets
to them?

I have an A97 database table (tblCorrespondence] in a database
installed at 2 sites. The table's key field is not a
natural key - its an autonumber field. Here are the values at the
2 sites. First, site #1. Then, site #2. If you plot them, you'll see
why I'm worried - I'm afraid I'll be running out-a-numbers soon.
For the life of me, I have no clue why they're not incrementing
by 1. Hope someone can help.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
