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?
How can i generate automatic reference numbers that can serve as primary key.
I want the prefix to include year. Eg Tr/yyy/incremental number...
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?
THX in advance
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?
View 2 Replies View RelatedI 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

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!
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
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?
View 14 Replies View RelatedIs there a way I can format AutoNumber for a primary key, for example, have the first ID start as C001 then for the next entry Access will automatically go to C002, and so on and so forth?
View 14 Replies View RelatedHello,
I am new to the world of databases, and I would like to know the easiest way to have a column with auto incrementing numbers.
I want that everytime a user enter data in a form, the new record goes into the database with a unique number.
thanks in advance
I have an infopath form, which people in my company can fill out to order parts. The form is linked to an Access database. The primary keys for the database are the Order Number and the Line Number (where the specific part info is in the system). The form also takes info about who entered the order, when they entered it, etc.
My problem is that while the form will be used for only one order, it may be used to order multiple parts. So the infopath form has a repeating section with a table where they can enter multiple line numbers and part names, etc.If I use the form to enter just one part, everything works great. But when I use the repeating section to add multiple parts, the information specific to the repeating section is added to the database but the rest of the information (who entered, when the entered, etc) isn't.
My intial idea was that since the first part is entered correctly and the subsequent parts are missing some information which is already in another line in the database. Maybe if there was a way to pull the information from another line into the lines with missing info within access would solve my problem. So basically automatically populating the rows with matching Order Numbers with the information that is missing.
Hi There,
I have a table that has two numbers, both require incrementing with each record.
These take the form of "00"0"/05" and "Book11 Enc"0.
I want these to update automatically but Access won't let me use two autonumbers in same form. Does anyone have a suggestion to get round it ?
Thanks.
Alex.
I have a field for SSN. If the SSN has a 0 or 00 as the first numbers it auto deletes those numbers. Is there a way in access that when the record is visible the 0's are relpaced so that the SSN will read the 9 digit. Also i have another fiels EIN with 7 digits an i need for there to be 2 9's in the beginning. I was goingto use vba but when i go to yp it i only get .value <
Code:
Me.SSN.Value
Value is tho only option to get. IDK y it does this or how to get it to shop if there is a ay.
Ineed to track Trailer security seals that are sequentially numbered with 8 digit numbers...They are physical seals and no efile with the numbers to upload into Access...is there a way I can put in a range and Access will populate the rest in a table?

Why does it have a random number like "17" when I DO NOT have the first 17 customers !
I have an Access DB with a VB 6.0 front-end. I have a table with a PK that uses an auto-number. I deleted from data from this table in the past, then re-added it back in again just now. However, now when I go to enter a record in this table from the VB executable, I am getting an error for duplicate keys--as the auto-number tries to use a number that already exists. This happens when I just enter a record directly in the table in the DB also.
View 1 Replies View RelatedI would like to expand on this questions. I would like to generate a number based on a reference I use, a format like "14/000" where I use "14" with the last 2 digits of the year. However i want the auto number to generate the the last 2 digit automatically when the year changes i.e. when 2015 comes the field generates "15/000" without any prompt from the user.
View 1 Replies View RelatedI have a very basic application to manage the tasks. In the main form "Tasks" one of the field is the priority (Order by) and I have this example:
Task Priority
B 1
A 2
C 3
E 4
D 5
If the user change one priority, I need a code to automatically change the others too respecting the new priority order. For example if the user change the priority 3 to 1 for the task C, the other numbers have to change to become:
Task Priority
C 1
B 2
A 3
E 4
D 5
There is a way to do this?
I have inherited an Access DB that is supposed to be kept "alive" but not made much better. On a weekly basis I get an Excel CSV that I'm supposed to import into one massive table; that works just fine.
However, there is another query that takes values from a table named "New Users From Import Table" and appends them to the current "User" table.
But before running that query I have to manually update a field called "Display Name ID" with the next highest number from the User table but only the highest value that isn't in the 9000 number range.
For example, my next highest "Display Name ID" is 1144, which of course does not include the records that range between 9000 - 9008.
I had to manually enter 89 "Display Name ID" values yesterday and I know there has to be a way to update that field when I pull the data over from the temp table without having to do it all manually.
Here's the query that pulls the data into the "User" table (after I've manually entered the incremented values).
INSERT INTO Users ( [Display Name ID], [User Type], Organization, [Display Name], [Alias Name] )
SELECT [New Users From Import Table].[Display Name ID], [New Users From Import Table].[User Type], [New Users From Import Table].Organization, [New Users From Import Table].[Display Name], [New Users From Import Table].[Alias Name]
FROM [New Users From Import Table];
how to auto increment one field based on the value in another field. What I have is a table with six fields. There is a foreign key assigned to each record and linked to another table. Four fields in this table are number fields indicating accordingly a number for a category, a number for a subcategory, a number for a subject for a subcategory and a number for an instruction for each subject of subcategory. The last field is the text field for each instruction. Numbers are required to be included in the report. Also, number of categories, subcategories, subjects and instructions vary by each record in the the table which this table is linked to. What I'm trying to accomplish is to have numbers in the subcategory to auto increment starting with "1" for each number in the category field, numbers for each subject field would auto increment starting with "1" for each number in the subcategory field, and numbers in the instructions field to auto increment for each number in the subject field starting, again, with "1". I also need these numbers to restart with "1" for each new record in another table.
Basically, the table would look like this:
cat subcat subj instruction
1------1-------1------1
1------1-------2------1
1------2-------1------1
2------1-------1------1
2------1-------2------1
3------1-------1------1
3------1-------2------1
1------1-------1------1
(if the record in another table is a new/next table)and so forth..I have been looking for anything that could remotely work for me. Every VBA code I've tried is either don't work the way I need it to work, other codes making the field to continue increment numbers if the number already exists in the other field.
I need to create a MemberID field that autonumbers and uses a prefix.
EG: YearJoined+0001
I want this as a the PK as well.I tried a default value Year(Now())&format([ID],"0000") but it gives me errors.
I have the auto ID number set up set up on my Access database which gives me membership numbers. How do I have a supplementary auto numbering column to give me invoice numbers. You used to be able to do this automatically up until a few years ago. Now I have to enter them manually.
View 8 Replies View RelatedI have a table, at the table I'v got these fields:
ID | num1 | num2 | sum
I want that the user put numbers at 'num1' and 'num2' fields and then the 'sum' field will calculate automatically the operator (sum=num1+num2).
I've tried to put any combination at 'Default value' of the sum field (all the fields are numbers , also tried to change the sum field to text...nothing works).
I'm getting a message that 'num1' field is not recognize at the table
(I tried =[num1]+[num2], without the '=', num1.table+num2.table , ...nothing works)
I also tried to do it with SQL command but it dosn't work.
There is any way to do it, is it possible? Or other way to do it at least at Form or at Report ?
