I have new database in this database i make primary key to field (ID NUMBER)
I enter data in this database just copy and past
If I enter any ID Number which is already in database , this database is stock
How I avoid this problem and how I let this database to accept other ID Number which is not in database and ignore other?
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.
Hi
How can you set a primary key number (autonumber) to start from a particular number - eg "10000"
I have invoices issued from an old accounts package - and am creating a new database to replace it, but do not want to duplicate old invoice numbers. I seem to remember in the past a way of setting this but cant remember - any help please ?
Thanks
Hi there.
I am creating a database and i have the layout I want. although I am having problems as i am using autonumber as the primary key in each of the tables. Is there are way to make this work as the data to be entered into this database does not have a natural key until they are 4 months into the process.
i have attached my relationships diagram.
if it is not a good idea to use an auto number as the primary key does anyone have any suggestions as to what i should use?
Hello ALL,
I want to know how to reset (to start again from 1) my primary key field. As an example i have the "Customers" table with the field "customerID" as PK now i entered many values (20) then i deleted them but i want to start again and the "customerID" value starts with 21 i understand that but i want a fresh DB (i was testing things) and i want to start from 1 can i? how? i even deleted the relation between this table and the other table but no success!
Some help please?

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

Can I change the primary key currently set to my products description to an auto number? I'm trying to make things right, also does the foreign key get an auto number?

How can I make the primary key (participant #) in my table equal the record number on the Form? In other words, when I open the form, I need two things to always happen:
1. the primary key must equal the record number (which is displayed on the form)&
2. when I click "Add New Record" button, I want a new customer # automatically generated and in the correct order.
Is this possible? I've been struggling...
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?

I have a form where we fill in information for supply of equipment to employees.
Each item must be signed for on a printed report.
I am encountering problems trying to create enough rows in my report detail for each signature of the items supplied.
For example, on the form I will select the "equipment" - 4 hats supplied and 3 boots. On the report I want the equipment set as the group and the detail to be a number or rows which equals the number of selected items. therefore under the Hats group heading I want 4 blank rows which are made up of 3 text boxes - Print Name, Signature & Date and another group heading for boots but with 3 lines.
I have a access table with 32 columns and 42,000 rows of numbers. I need to find the MIN number in the row and if the MIN number has duplicates then I need them all placed into another column by column name.
Example:
Starting file
DEST,ORIGIN1,ORIGIN2,ORIGIN3,ORIGIN4, ETC
05512,3,2,4,2
ENDING table needed
DEST,ORIGIN1,ORIGIN2,ORIGIN3,ORIGIN4, NEWCOLUMNname
05512,3,2,4,2,2 ORIGIN2 ORIGIN4
Where the new column name contains the MIN number in the row and all of the associated duplicates column names.

Hello,
I have a basic question about choosing the primary key for a table. Now I am not really concerned on the particular field(s) chosen to be the primary key, but rather the potential states, if you will, that the key can be in.
Say I choose a multiple field primary key for a contact table of, say, LastName, FirstName, and PhoneNum.
I thought during an Access db project I was updating awhile ago using Access 97, it didn't require EVERY field of the multiple primary key to be filled in, as long as there was enough to make a unique key.
I am wondering if this is still the case for Access2000 primarily. From what I have read it appears that this is not the case or at least it is strongly not recommended. For my example would it be to have FirstName and LastName filled in but not PhoneNum. Then, if a new Contact were added with the same LastName and FirstName but a PhoneNum was also added, the PrimaryKey would essentially be unique still.
I know this definitely isn't the best example but it still states my point.
If anybody has any wisdom on the subject I'd greatly appreciate it!
Thanks! :)

I think that creating a new primary key is the only solution to this problem, but I would love to have other input, including potential pitfalls I might encounter in this process.
Here is the scenario: I have spent the past year creating a "survey based" database in my "spare" time at work. The database holds detailed information about nutrition questionnaires given to children over the years that they are in our program. I have based the structure on using ClientID as the primary key. ClientID = each individual's social security number.
We have another database that holds all the client's information. This is the database where any updates are done to their information. I export the client information (firstname, lastname, birthdate, socialsecurity, plus a few more) that I need into excel. Then I import that info into my database on a regular basis using an update/append query.
We started using the database in September and all was going well until a few weeks ago when I imported data and found a name that was entered twice. On looking closer, I found that the person had two different ClientID's. How could this happen...? Well, in our other database, if a child doesn't have a social security number yet, or we weren't given it, the program creates a fake social security number AAA-##-####. I knew this from the beginning, but wasn't aware of any problem. However, I was missing a significant piece of information. When the child finally does receive a SS#, we go in and change the number in the program!!!! At first I was told this rarely happens (I had about 6 duplicates the first time), but today I ran another import and found 90 instances of duplicated names!
There are just over 600 records in the database. Many of these have had information that is unique to this database entered in a related table, so I need to be sure I don't lose any of that data. There is data in other tables that I could import again if I have to.
Here are my options as I see them:
1. Leave the primary key alone and delete the duplicated values with every update.
2. Create a new unique autonumber primary key, knowing I will have to delete relationships and rebuild them. I would leave the clientID field in the system as it is the only way we have to determine the difference between two children with the same names and birthdates.
3. Run quietly away hoping they don't notice the problem until I am long gone. ;)
What would you do in these circumstances? If you agree with my assessment that I really should create a new primary key, what steps would you take to minimize problems both during the process and in the future?
And yes, I wish about 12 months ago, I had asked if the social security number was ever updated, but of course no one thought to bring that up when we were discussing the database design! :mad:
Thanks for your help!
I have some employee data to import into Access but this data does not have employee ID numbers. I would like to assign employeeID numbers to each person then set the employeeID field as the primary key.
Here is what I had in mind. I would create a table that defines each employee with an EmployeeID number. Then in the table containing the imported data, the first field would be called EmployeeID. After importing the Excel data into this table, initially this EmployeeID column would be blank because the data in the Excel file doesn't have an employeeID. But the employeeID field would have a VLOOKUP formula that would look at each person's name and cross reference that with the employeeID table in order to obtain the employee ID for each person on each row. Then the VLOOKUP would return the employeeID number. Furthermore, I would like to have this employeeID field set as the primary key.
Can you do a VLOOKUP in Access? If so, can the employeeID field still be used as the primary key field, even though its values would be determined by a VLOOKUP?
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.
Hi guys,
I am having problem with a query.
I have to tables. One named wire and the other named Input.
As my title says there is not unique ID for the tables to relate.. the only thing to relate is one ID where is not unique for all the rows
In the Wire Table I have 3 rows using the same ID, lets say 123.
In the Input Table I have 1 row using the same ID as above, i.e. 123
I need to select a couple of fields from Wire Table and 1 field from Input Table
The only relationship I have is the ID 123.... since the ID in Wire Table is repeated in 3 rows.... I would like to use the same value from the Input Table to be the same for the 3 rows in the other table.. Below is an example:
Wire Table:
ID Group
123 A
123 B
123 C
Input Table
ID Description
123 Analog
My wanted result would be
Group Description
A Analog
B Analog
C Analog
I tried using the Left join or Join function, but somehow the resulting table has many duplicates of the rows...such as:
Group Description
A Analog
A Analog
A Analog
A Analog
A Analog
B Analog
B Analog
B Analog
B Analog
...
Any Idea on whats going on and how can i solve this problem????
Thanks in advance. Your Help is much appreciated
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,
I have a database with 200.000 records, how I Add Primary Key Field.
I'm getting error "File sharing count exceeded..", tried to increase "MaxLocksPerFile" registry , but without success.
I have a table with more than 700,000 records. There are no unique fields or unique combination of fields. I would like to add an AutoNumber field but when I try I get the message:
File sharing lock count exceeded. Increase MaxLocksPerFile registry entry.
If I answer yes I get an error that the new field was not added. Is there any way to add a key foield to an existing database?
Hey Guys
I'm having abit of bother with a database I'm fooling around with.
Basically it has 4 main tables at the moment.
Personal Details
Participant ID (Autonumber)
etc
Training Details
Participant ID (Number)
Attendance ID (Text Field) Auto generated by expression =[Participant ID]&[Course Code]&[Level Code]
etc
Attendance Records
Attendance ID (Text Field)
Review ID (Text Field) Auto generated by expression =[Attendance ID]&[Month]
Reviews
Review ID (Text Field)
etc
These tables are linked by standard one to many relationships. (http://www.flamingbird.com/relationship.png)
Everything worked fine until I decided to Auto Generate the Attendance IDs and Review IDs to save confusion amongst those administering it.
Now it reports when I try to add a new record to the tables with the Auto generated IDs that:-
Index or Primary Key cannot contain a null value.
It appears the auto generated ID's are being mistaken for NULL values!
Anyone any ideas as to why this is happening? This is really my first time trying anything this complex, every other database I've done relied heavily on the data inputer.
Oh and its Office 2003, but the database is in 2000 format cos not all the office has office 2003 just the training end.
Many thanks
