Customized Primary Key With Auto Number

Oct 6, 2004

Hello,
I am a beginner and know a little about access. I am trying to create a customized Primary Key with an auto number. I want it to look like this: VP001 ,next record, VP002 and so forth. When I enter a new record and want it to do this automatically. It could be VP1, then VP2, I don't need the extra zeros but it would be nice. I don't know how to do this. If someone could please help walk me through this. Remember I am a beginner with databases and need help.

I would appreciate it

Thanks

Tables :: Text As Primary Key Vs Auto Number

Jun 19, 2013

When I first was making my database I used all auto numbers for PK's. But then I read an article or two saying that you really don't need to do that if you don't have to (actually, the article said "don't use autonumber if you want anyone to understand your database). I have a few tables (most employee experience type tables) where I just use the word as the PK and there is no auto number in the table at all.I continue to build my database?

General :: Auto Number PK Change Starting Number?

Dec 18, 2013

I have a table with an auto number PK. This table will contain orders. I'd like to use the PK from this table as the Invoice number on the invoice. I'd like to have it start at a number other than "1" just because it looks better on an invoice. I don't know how to do this. I looked at the table design to see if there were options available to me there but couldn't find anything. Is it possible? (I do not know how to use code.)

Appending Records With A Desired Auto Number In A Table With Auto Number

Oct 26, 2005

Here is my issue. In a table with an Auto Number index some records have been deleted. I have been able to recreate them along with their original auto number. The problem is that I do not know how to append these records forcing the original auto number. I have tried changing the auto number field to a number field in the table, this works except I cannot change it back to auto number.

I am sure I’m not the first with this question or issue. I did search through a couple hundred entries about auto number before I posted this question.

Primary Key Auto Numbers

May 21, 2007

I have used priamry keys in my tables and these are set to auto numbers on the advise of fellow forumites.

One question if at the end of every year I need to upload batches of data to my tables, this would mean I would need to go through each record and manually enter the foreign keys in the linked table.

Surely Access has a better way of dealing with this issue?

Change Primary Key And Update Data?

Jul 25, 2007

Hello,

Firstly, I am very much self-taught on access, so there are several gaping holes in my knowledge, and my database structure is probably not wonderful! I have been learning as I go along, so in the initial stages I have built in several problems which I am now discovering!

My db is designed to track suggestions - i have a table where the idea, progress etc is stored [tblIdeasBank]. This contains an 'originator' (person's name) which is linked to a second table, where the names are stored [tblPeople].

Originally I set up tblPeople with the Primary Key as FullName (e.g. Joe Bloggs) (guaranteed to be unique with the small number of people that would be involved), and a second field called InitialLastName (e.g. J Bloggs). It is this second field that is stored in the tblIdeasBank. Data verification came from the user having to select a name from a drop down box, so there is no actual 'relationship' between the tables. (Didn't realise how useful they were at the time!)

The db has been so successful :confused: that it is now going to be rolled out across the company, which gives me two problems. To populate all the names, I need to import them from Excel, where I will have FirstName and LastName. I have now realised that it would be more sensible to just store these, and create InitialLastName where needed. Also, I may well have duplicate names, so I need to create a unique ID, and a proper relationship. (Yes, I know I should have done that in the first place).

So, I have:

tblPeople:
.FullName (Primary Key)
.InitialLastName

tblIdeasBank:
.Originator (stored as InitialLastName)


And I would like:

tblPeople:
.PersonID (Primary Key)
.FirstName
.LastName

tblIdeasBank:
.IdeaID (Primary Key)
.Originator (stored as PersonID)

With a One-Many relationship from PersonID to Originator

Any ideas how I would go about doing this and changing the Originator for each idea from InitialLastName to the relevant PersonID number, without corrupting the data?

I have searched through Google and various groups, but cannot find a useful answer, so any pointers gratefully appreciated!

Thanks,

Nick

Forms :: Auto Generate File Number Based On Number Of Records In Year

Jan 21, 2014

I have a form [IUDATA]

I have a add record button.

I have a date field [DATEIN]

I have a text field [DRPNO]

If the [DPRNO] field is empty, I would like the user to have the [DPRNO] field be automatically populated after the user enters a date.

I'd like the format of [DPRNO] to be "dpr YY-XXX"

Where:
YY is the year of the [DATEIN] field and
XXX is number of records in that year.

So for example, if it was the 4th record with a 2013 date the [DPRNO] would be dpr 13-004.

Uniqueness Of Auto Generated Primary Keys

Jul 13, 2006

I am developing a DB that is composed of approximately 50 tables. The primary key in every table is automatically generated byAccess. I understand that the primary key for each record in the table has to be unique. My question is: Is the primary key uniqueness applicable across the entire DB?

For example, table A has a auto gen key #25 in it. Therefore, no key in table A can be #25. Now I make an entry in table B (A:B, is 1:many). Can the primary key in table B be #25? OR, once #25 is used and continues to exist, it cannot be used in *any* table?

I have made several small examples and the keys across all the tables are unique. I don't know if this is guranteed across all the db tables, or just in my particular case?
Thanks
John

Importing Data Problem (auto Primary Key)

Aug 11, 2006

Hi all, I currently have 2 databases: a main current database (Main.mdb), and a secondary database (Working.mdb).

They are identical, except the working database has no data, just the existing tables, forms, etc. from the main database.

When I (or a programmer) makes changes to the forms and some underlying calculations, they are first made in the Working database.

After the changes are made, i delete all the data from the tables in the working database (data from testing, etc.). I will then copy all of the data from the tables in the Main Database over to the Working database, then rename the Working Database to the Main Database.

The only problem I'm having right now is that the primary key in one of the tables (ClientID) is an autonumber. When I paste the data into the Working Database, all the ClientID numbers change. Is there any way to keep the numbers the same as the Main database?

Thanks in advance!

Make Table Query With Auto Primary Key Help

Jan 24, 2007

Anyone...
Please can you tell me how I run a make table query that makes one of the fields a primary key. Can it be done in the query or do I have to set it as part of a macro that runs the query. If so How do I achieve this.

I am running a make table query from a link table so i can use it with infopath. I run the make table query every time I update the spreadsheet that the link table runs off and it makes a proper table with it for infopath to run off (because I can't get infopath to run off a link table, No primary key means it won't submit.) When I run the macro that runs the query and creates the table, I need it to make oone of the fields a primary key.

Any suggestions

Auto Increasing A Number, Depending On Maximum Number When Condition Is Met

Sep 18, 2006

Hi,

I'm trying to get the maximum number in a table field to increase it by one depending on the member that is selected in a drop down in a field.

I have three tables: members, programs and times. Each member can have N programs and each program can be broadcast N times.

Each member has a three digit code, like XXX. Each program has the three digit code of the member + three numbers that are supposed to auto increment. That is, the first program of member X with the member code XXX is called XXX001.

What I'm trying to do is that when a new program is filled in and I select the member, then the program code should update automatically, adding one to the latest program by that member.

That is, if the last program by member X that was inserted in the database is XXX010, then if a new program is inserted it should automatically be XXX011, even though programs by other members have been added in between.

This is the code I use now, for the AfterUpdate when selecting the member in a dropdown in the form. But although I've played around a bit, I just get error messages...

Private Sub medlemsruta_AfterUpdate()
Dim medlemskod
medlemskod = Me![medlemsruta].Column(2)

Dim strMax As String

strMax = DMax("programs_kod", "table_programs", "Left$(programs_kod, 3) = medlemskod")
Me!program_kod = Left$(strMax, 3) & Format$(Val(Right$(strMax, 3)) + 1, "000")
End Sub

Medlemsruta is a dropdown where one selects the member from the members table, where the three digit code is in the third column (Column(2)).

I'm trying to use DMax to get the maximum number for the particular member and after that adding 1 to that for the new program code.

Grateful for any advice! Thanks!

Change Primary Key / Data In Related Table

Oct 18, 2011

I am new to access 2010. I need to change the primary key in a table ("stations", Primary key is "station number"), because future entries will result in double entries for this primary key.

I have another table ("species&stations") which has records of Species for each "station number".

So I created a new Primary key for the "stations" table, now called "species id", being a bit better in defining a unique station (as it contains the year and the species number, i.e. "451_2010")

Now the table "species&stations" references/(is in relationship with) the old primary key, identifying a station number for each record.

How do I get it to recognise the new primary key from the "stations" table, and keeping the records (over 1000...) with all there info.

Approach so far: I tried to create a new field in "species&stations", which should look up the new primary key from "stations" and then autofill the field. i did not manage this though

I attached a screenshot to make the relationships more clear!

Query That Result Incremental Number, With No Auto-Number

Sep 10, 2006

Well, here's my database :

Name : String
Address : String

I want to add an automatically generated column, "no.", to show which number it's in. Like this :

No. Name Address
1. A Unknown
2. B Unknown2

The problem is, I can do that with Auto-Number, but if the user delete row 1, the number in row 2 is still 2, not 1.

Is it possible to generate query that have "no." column in it ?
