Set ID Primary Key (autonumber) Field Back To ZERO
Sep 30, 2005
Hi there,
strange query... I have a testing database which I have filled full of test data. I now want to create an empty copy of this database, so I copied this, removed all records, however the tables where I have a field named ID, which is the Primary Key field and is Autonumber set to increment, I cant seem to get this to set back to 1. I tried deleting the ID field completely, closing DB, and adding it again, yet it STILL remembers the next number up from the last record I had created previously??
Can anyone offer any help as to how I can get this set back to 1, as now I am finished testing I want to essentially start all table records fresh.
Many thanks for your help as always,

Hi,
The database I've inherited has a primary key autonumber set up which is randomly generating numbers. It also has another field which has yet to be used, of a clients reference number.
I thought it would make sense to use the reference number field as the primary key, as it seems redundant otherwise and it would give us another field to perform searches on (if we record a clients reference number on their paper file, then finding them on the database would be much quicker).
Because of the relationships in the database, I didn't want to remove the existing primary key as I'm afraid it would mess up the whole thing. I was wondering if there is a way of having the autonumber which is generated in the primary key to be automatically copied to the clients reference number field? This would leave the primary key intact but give us this extra level of information to search on.
Thanks.

How can I insert an 'ID' field into an existing table at first field as primary key using AutoNumber? The table will then be populated.

the autonumber datatype in access automatically adds numbers when a new record is added, since i have been using it to test my database new users already started at 100, without creating a new table how do you change it back to 0.

My shiny new database is ready to go - now I have deleted all my trial data and want to re-set the autonumber primary key of my main table to start at "1" (I thought I could delete it and re-insert it but it won't let me). Suggestions?

Just a general question...
When you make a primary key is it better to use and Autonumber or a Custom one? I have for the most part used auto...easy, convienient and well I have never had a problem yet (been pretty serious on Access for about 1 year). But I just read that ref integ doesn't work on Autonumbers? which would also mean cascading update & deleting correct?
I have looked at Northwind Access sample and all except "Customer" they use Auto. Well then to make a custom Primary field wouldn't I have to do that at the form level? like "CustomPrimKey = Left([CustFirstName],2 & Left([CustLastName],2) & [PriKeySetAtAutoNum]" or something like that to get what I want. I imagine you would automate this as opposed to letting the operator manually enter them.
And then as in the Northwind sample how do you know which tables need the custom numbering and which ones don't.
As I have learned on my own some of the "basics" elude me until they come back to bite me.
Thanks

Any ideas on tagging my primary key (currently autonum as a data type) with an "M" on the front of it. I guess i wanted to keep it as autonumber so i wouldn't have to key in a value
Thought maybe i could create a new field and do an "M" & [ID] in the default value where [ID] is the autonum primary key field but I guess I'm not doing it right - get an error trying to save saying it can't find the field [ID]
thanks for any suggestions!

Hi!
I am a new member of this forum and new to access.
I need to make a data base and I would to have my primary Key as an autonumber. I would like to use ID numbers that have already been assigned but they have letters in the beginning, they are GKAD0001 etc. so at the moment I just have them as text that wont allow duplicates, but really I would like them as and autonumber so when new data is added it automatically assigns the next number.
Is this possible?
Thankyou very much for your help.

Hi,
I need to create a table with 2 sets of different information both referring to job types. the problem is that i need the autonumber which created the job number to scale together. so both tables have a primary key of "job number" and i want the autonumber to only ever use 1 number in both tables.
e.g.
job type 1 - autonumbers - 1,2,3,4,6,7,9,10
job type 2 - autonumbers - 5,8,11,12
is there anyway of achieving this?
Any help greatly appreciated

I am new to Access, and have spent the last few weeks reading everything I could get my hands on about creating databases. I am working on a new database for my office and I need some help please.
I am trying to create normalized tables, so I have broken down my tables into the smallest possible field groups and linked the tables via primary and foreign keys using autonumbers and the primary key in parent tables. My question is how do I have my users interface in forms with actual data instead of the ID numbers but have the ID numbers inserted in the field. Here is a sample of my address table to demonstrate my question:
tblAddresses
AddressID Autonumber PK
StaffID Number (FK to tblStaff)
AddressTypeID Number (FK to tblAddressType)
Address1
Address2
CityID Number (FK to tblCities)
StateID Number (FK to tblStates)
ZipID Number (FK to tblZips)
Obviously all of my tables are not shown here but this should show what I am looking for.
So, how can I let the user input/select the actual data from the forms in combo and text boxes but actually input the ID numbers into the underlying tables. If a user is inserting a new record and selects state I want them to be able to input/select CA not the StateID 1.
I don't know why I am having such a hard time with this, I seem to understand the other concepts but this one has me stumped. I found a few ways to do it, but I don't think they are right and I want to learn this the correct way. Any help is greatly appreciated, thanks!

I have three tables.
EAch has a field called ID that is an Autonumber that is the primary key.
When I enter data via a form each record has a different ID across the three tables.
Does this mean they are not linking up correctly?
I have attached my databaset if that helps.
Thanks.

I have a table that has a primary key that does an autonumber in increments. Then I made some queries that will append records by date and then also another query that will delete what was appended. Then I created a reverse sequence of this process in case I change my mind and would like to put back the records I archived, however, when I do this, the primary key is now thrown off and will still revert to the last primary key that was appended before the archive ever took place. In other words it still thinks that the records I appended before I did the reverse, are still there. So now it will not let me save the record because it is a duplicate.
Is there a way to set the autonumber for the primary key to where I want it to begin?

I've just begun using microsoft access and would like to create a primary key on a table of data that has been sorted alphabetically. However, when I try to create this key (designview -> auto number-> increment) it autonumbers for the column the way it was before i sorted it. Is there a known way of doing this?

I have an existing contact information database which consists of a number of tables, the main table has a primary key which is currently set to NUMBER.
There is a relationship between it and 2 other tables via that key (ContactID).
I would now like to change the primary key (ContactID) to AUTONUMBER, so that any new records added, have a number assigned automatically. I also need any newly created primary key number to be used in the child tables created as a result.
Is this possible ? (without renumbering my existing tables/records)
many thanks

I have a simple database that I inherited, that contains basic customer contact info. We want to start adding more functionality to the database, so I've done alot of research to learn about how to begin normalizing my data.The existing table does not contain a useful primary key, since we may have multiple individuals from the same company, companies with very similar names, etc.
I would like to add an AutoNumbered field to use as a CustomerID/primary key, but I can't seem to find a way to do so. Here is what I've tried so far:
I have tried to add a field to the table, and make it an AutoNumber data type. When I do so, I can error message saying that I cannot make a field AutoNumber if any other field in the table already has data entered in it.I have tried to create a new table containing only an AutoNumber PrimaryID field, and then import data from the existing table, but that just creates a 3rd table.

The above image is of a table which I need to update according to a new data on daily basis. As you can see when I added two records at the last , the AutoNumber primary key of the table jumped by thousands . I have used the following query to update the table
Code:
db.Execute "INSERT INTO D_Counterparty (CPTY_ENTITY_ID,CPTY_DESC)"_ & "SELECT Ctpy_Entity_Id,Ctpy_Entity_Legal_Nm"_ & "FROM NewCU LEFT JOIN D_Counterparty ON D_Counterparty.CPTY_ENTITY_ID=NewCU.Ctpy_Entity_Id"
I never changed the AutoNumber from incremental to random and I have also tried re-seeding it but had no success. Also when I inserted the sample values using a sample table ,the AutoNumber was working fine . Here's that query
Code:
db.Execute "INSERT INTO D_Counterparty (CPTY_ENTITY_ID,CPTY_DESC,) SELECT a,b, FROM sample"
I did not use join in this query ...

I have two tables linked to each other in one to many relationship. Instead of auto number, the date and shift (Text) is being used as the primary keys (Composite Primary Key). Here is the tables structures,
Payouts Table:
Date: Primary Key
Shift (Day or Night) : Primary Key
Bills Table:
Date: Primary Key
Shift (Day or Night): Primary Key
Autonumber: Primary Key
The tables Payouts and Bills has one to many relationship. One payout row can have many bills. The problem is that I want to start the Autonumber in bills table everyday from 1. As date and shift are different for every day so even if i start bills from 1 everyday, it wont make same primary key. I can do it manually but I want to make it automatically.

Assuming the following table:
Album ID AlbumTitle Song Rating
New
When I enter data, Album ID increases every time I jump to the next field. For example, when I enter: AlbumTitle, Song, Rating, Album ID is already at 4 and this is just the first record.

I have an autonumber field that somehow got reset back to one. Is there anyway to reset this number, I need it to be back around 1900.
This is a big problem because I use the auto number as an order number and also use that number to link the options selected to that order. Now that it has reset to one, it is picking up options from the original order number one.
Any suggestions?
Addtl Info. This is in an Order Table. When the order is ready for manufacturing it is assigned a serial number and the order is deleted from the order table and put into a production table.

I have a primary key field called "Issue Number", with the properties set to auto-number.
After testing, I need to set it back to zero before going live.
I deleted all the records and did a compact and repair, but the first number that comes up is the one after the last one used during testing.
Help????

Is there a way to change the back color of an active field in a form? Meaning, when I tab through my form and the field I tab to becomes active, the field turns white. This poses a problem because my form back color is black and my field text is white. When the field is active, I can't see the value in the field due to the back color defaulting to white. Does this make sense? Is there a way to change it?

So I have a control called txtBranch. If the user does not put 1 of 4 options then a msgbox pops up and says that is an invalid option and then gives all the valid options. It then sets the value to blank. Then it moves to the next field. I do not want it to move to the next field. I want it to stay on txtBRanch till it has a correct value. I have tried DoCmd.GoToControl "txtBranch", Me.txtBranch.SetFocus on the OnExit, OnLostFocus, AfterUpdate events and it still continues to go to the next control how do I get it not to go to the next control?
