Need To Have A Unique Number Across Several Different Tables
Jul 21, 2006
Ok,
Bacically I have 2 different lists (well there will be 7 in total):
tblValves
ValveID
KKS_no
Description
List - specifies thats its in the valves list
TOP_Code
tblSpools (pipe sections)
SpoolID
SpoolTagNo
Description
List - specifies thats its in the spools list
TOP_Code
The reason that I have kept these two in different tables rather than combining them is because the spools table will relate to a few tables that will have nothing to do with valves. For instance the spools table will relate to a table called tblPipeSupports.
The thing is this: I would like if there was a unique number across both tables. Collectively the items in coth tables are called components. Some of the components from either table will have drawing numbers for instance so I would like if I could have a table:
tblDrawings
DrawingID
DrawingTitle
ComponentID (FK to valveID or spoolID)
However this won't work because valveID or SpoolID could have the same numbers. I could use a composit key like SpoolID + List but I think I'm probally making it more complicated than necessary. Also I'll have several tables like the drawing table e.g. some of the components will belong in the testPack table... And I'l have to repeat that List field in each..
So what do I do?

What I have is a small POS system I'm trying to create a unique invoice number for each transaction (multiple records)
I have two tables, one named "CurrentTransactions" and one named "Past Transactions".
I have everything working except the invoice number my system works by adding pre defined records into the table "CurrentTransactions" and once the sale has been finalised it transfers the data to the "PastTransactions" table.
take the last number from the "PastTransactions"."InvoiceNumber" to create an invoice number in the "CurrentTransactions", and I want to be able to do it using an expression in the default value property as opposed to in the form ( I've tried the form way but using Dmax would require me to almost rebuild my entire POS system )

Hi There,
I am setting up a basic Data Licence database. For each new record I enter I want a unique number to appear at the top of my form that can not be changed. I would like the number to be the date it is entered plus the auto number so, YYMMDD-(auto number) eg 071001-1. I'm sure it's something simple but I am only new to access.
Also while I'm here, on my form I have a Product field, how can I make it so I can enter in more then one product?
I would really appreciate any help!
Thank you,
Dane

Hello i want to create a tracking number based on information entered into a form.
So i have my main table called "MainData" and this is in the backend and linked through to the front end where my form is.
I then have a query which is called "calllog" which has a field called "Call Number" inwhich i placed the following
=Year([Date]) & Left([CustomerName],3) & Right([Date Created],2)
This then gives me a unique number. Once i have entered a job in it will generate a number. Now this part works fine but it does not update the Maindata. How can i get the this to transfer the data to the maindata table???

I am selling some products, namely A to M. I record the orders of costumers in a table, named "orders". For example, if costumer "Jack" has ordered as the following:
Code:
ID costumer product quantity unitprice orderdate
12 jack A 4 10 25/11/2014
13 jack B 5 5 25/11/2014
14 jack C 1 4 25/11/2014
15 jack F 3 2 25/11/2014
16 Jack G 4 8 25/11/2014
17 Jack H 1 7 25/11/2014
Then I make a report based on the above table and issue that as the invoice to the costumer, who is jack here.
How can I make a unique invoice number, which automatically increases sequentially for each invoice? Do I need to add a new column to the table? I also need to be able to look for a specific invoice based on the number, or date.

I am trying to create an automatic unique 'number' (actually text) in a form. Here is an example of the format...
1456.R1
1456 is the project number
R stands for revision
1 is the first revision
So, in this database there could be 1456.R2 etc. but there could also be other project numbers, say 2323.R1, 2323. Looking for expression I need to enter to have Access look up the last revision for a specific project and then add 1 to it?

Example 1:
2011-1
.......
2011-3893 etc.
Currently I have an Access form which produces a new unique number to identify each new record created. To do this I use the unique ID autonumber from a table to identify the new records. I would like to change from this simple number to the the above format per example 1. The four digits to the left of the hyphen would always be the current year and digits to the right of the hyphen would be the unique auto incrementing numbers such as from my table. I need the year to auto increment by 1 each September 30th (new business year) and I need the numbers to the right to auto reset to 1 to start uniquely identifying records again for the new incremented year. As each record is closed I need the number to be written as a single entity in the new format to my database.
Example 2: After September 30th.
2012-1
.......
2012-447 etc.

Need to generate a unique reference number each record wise while data entering by a form. How to do this by using a command button ? After entering all fields related to the record, when click on the command button, unique reference number for that record need to be generated and save with all other data of the records. in a later event, need to recall the record by using this reference number and also need to make relation ship with some other table by using the reference number.

I have a set of transactions with a Unique ID field and a date. I want to add a field based that gives me the sequence of events for each Unique ID in order of when it happened.
For example, if customer X has 6 transactions, the sequence field would have a number (1-6) in each record that corresponds to the order in which those transactions occurred. The first transaction would have the number 1, the second would have the number 2 and so on.

Basically what I have is a database for tracking/logging parcels that arrive to the office. I want to be able to generate a reference number based on the date of arrival: i.e. the reference number should be ddmmyy### where ### is a sequential number. I know that I could just use the primary key's autonumber, for the sequential number but if I do this then the sequence will not restart at 1 on each date and because we receive a lot of parcels the reference number will grow to be too big to print out on the collection slips in just a few months.
two tables (one with the date and staff on duty that day and the other with the parcel's info') with a one to many relationship
I also have a query (Named: FullLog) that picks up the following data from the tables:
Name - Description - Size - TrackingInfo' - Staff - DateReceived - Count
The field named Count is a DCount function that I used to find out the number of times each date is repeated. This is the Expression that I used:
Count: DCount("*","FullLog","DateReceived = " & [DateReceived]) [Note that DateReceived is first converted into a string using CStr()]
This is as far as I have been able to get, I have been looking for weeks for a solution to this problem but I have yet to find one. I don't even know if the DCount function is the correct way of doing it, I did read somewhere that this produces a very slow query.
Effectively what I want to be able to get is something of that resembles the following
DateReceived - ReferenceNo
051013 051013001
051013 051013002
051013 051013003
061013 061013001
061013 061013002
071013 071013001
071013 071013002
071013 071013003
071013 071013004
071013 071013005
081013 081013001
081013 081013002
091013 091013001
101013 101013001

I have a rental database and I print several contacts for leases etc. what I want to do is have a unique reference number or something inserted to the report every time that it's printed. What I am trying to achieve is to keep track of which tenant corresponds to the report (Lease) printed by using reference number.
There is a seperate form which holds the tenants details and I would like to have a field on that form which would show the same reference number as the report so I can track which report was printed for who.
Whats the best/easiest way to accomplish this?

I want Access to automatically generate a reference number for a record based on the values in on two other fields for a given record using a form.
The first field is called Operation Number.
The second is Bag Number.
The reference number needs to be in this format: 19C.3.1
Where 19C is the Operation Number, 3 is the bag number, and 1 is automatically generated. Additionally I need the last number --the automatically generated one--to go back to 1 if with each new bag number.
This is kind of like library catalog numbers. Not sure how to do this.

I'm creating a database using existing data from an excel file full of contact details. What I need to add is a queue type system where each contact in the database has a "Place in Queue" number which is unique obviously.
Lets say Alan is number 1, Bob is 2 and Chris is 3. They have these corresponding numbers in the queue field for their entries.
Now what I need to have, through use of a form, is a way of changing Chris from number 3 in the queue to number 1 and thus have Alan automatically shift down to number 2 and Bob to 3.

Hi,
I have a situation and i do not know how to handle it.
I am developing an application for a lawyer. In the data base i have the following tables: Files, the people table (that are involved in a lawsuit), and other tables. The problem is the following: in the people table, beside the primary key i have another unique element that is social security number.
In the files table beside the primary key another unique element exists: the number and date of the file (File 1 from 15.02.2006). A lawsuit file can have more law terms: today it has one law term and maybe next week another law term so i must have the same file many times in the table with the same code and another date, but i cannot add the same file many times in the data base because a file has data about one person and the social security number of the person is unique.
If anyone can offer me a solution it would be good.
Thank you!

Dear all,
Many thanks for taking the time to read this.
I have a slight problem which seems like it should be easy to solve but I have no idea how to do it.
I have 2 tables (table1 and table2 for instance) Table2 contains more data than table1 but should contain everything in table1 as well as more.
How is it possible to return just records that are in table2 that are not in table1
Eg
Table1 contains:
IDab
112
222
322
422
511
611
711
Table2 contains:
IDab
112
222
322
422
511
611
711
833
The query should return just the line:
833
as this is unique.
thanks again

I have a table as followed;
EmployeeID: PK
FirstName
MInitial
LastName
Company:FK
Department:FK
What I want to do is create a new field that automatically populates based on what is entered into the above fields.
Essentially creating a single field with unique data generated by multiple fields.
For Example if I entered the following informaiton:
EmployeeID: 1 (AutoNumber)
FirstName: John
MInitial: P
LastName: Doe
Company: FederalGov
Department:Test
The new field can be generated as followed: JohnPDoeFederalgovTest
What i plan on doing with this is making this "generated" field an index so no new duplicated records can be added.

I have downloaded a contact template from the internet ready to go. There are few things I need to get rid off and make changes to.
One of the most improtant thing is making one of the field unique. For some reason, i can get to the design view. I open navigation panel and right click on the table, there is no such thing call design view on the menu.

I use Cognos to pull raw data from Oracle. I take this data and put it into Access 2010 tables to then run queries. Because the people creating the data in Oracle are often slow, I run back data to catch missed information, typically two months. For October, for example, I'll run October and also September and August.While I have new data, I also have a great deal of duplicate data. How can I ensure that I append only the new data and exclude the duplicate data?

I have 4 fields in a table that when combined must be unique.I know you can setup multiple fields as a combined key, but I don't really need these to be the key (I will auto number a unique key). I just need to make sure the same combination of codes is not entered twice.Do I set this up as multiple key fields anyway?

I have an Access2007/SQL Server 2012 system with 20 users for an insurance company. The company does most of its business via a network of vehicle dealers around the country. If someone comes in to buy a motorcycle, boat, or recreational vehicle at a dealership they need insurance to take it home, and our dealers send the quotes to us.
The dealers, in turn, receive payment from us each month for their efforts. Some are paid a % commission on the premium, some are paid for each quote they send regardless of whether the policy actually sells or not, and some are paid a set amount per sold policy. (Yes, that is relevant information!)
We already have reports that tally the amounts due each dealer based on their payment scheme, but last month our bookkeeper had to write about 650 checks manually because the check writing is not automated. She'd look at the report, and then enter name, address, and amount (in digits and words) into Quick Books and print the checks from there, a horribly tedious process. I've been asked to print the checks from Access. Basically one click would print all 650 checks.
I've opted to use a Make Table query to move the commissioned dealers amounts to a single location, and then to run two append queries to add the records from those paid per quote and those paid per policy. At the end of the day, one table contains all the information necessary to print the checks...except one.
The check number.
I need a way to sequentially number each record in the new table with a user generated starting point, the first check number.
By the way, the check blanks are on standard letter sized paper, three to a page, with tear-off perforations to separate them, in case that information has any relevance.
I think the best way to accomplish this is from the report itself. I've created a blank field on each record for the check number, and what seems most logical is that the sequential number is generated on print and written back to the table, rather than just generating all the numbers at once. That way, should print ever be interrupted, it will be easy to take up where we left off.

Greetings all! We have a mentor-mentee database that's been setup with a many-to-many design. We're storing essentially the same data in each table except for the field names. We thought we were good to go but one additional request was made to determine a count of employees participating in the program (regardless of whether mentor or mentee) in each section of the company. We don't want each person counted multiple times if they are both a mentor and a mentee, or if they have >1 mentee or >1. I created a couple of queries to pull unique empIDs from each table to narrow down each table BUT I'm stuck on being able to pull unique id's from both tables.
I first tried the unmatched query wizard from both viewpoints but then I don't get those cases where a mentor is also a mentee. In other attempts, I end up with a cartesian product. I've cruised through the queries section but haven't come up with any examples related to this type of situation.
I need a way to pull both unmatched records from each table while also getting essentially the first occurrence of instances where mentorID=MenteeId. I'm no SQL expert so if someone can think of a statement that would suffice, it would be greatly appreciated.

How i would best combine values in a table to produce a 'primary key id number.'
For example: the first letter of a city in the ID and the next number available/auto number - Portsmouth -> P233
I know i can create this in a query however i want it as the unique ID for that record entry in a table. If that doesn't make sense i can try to elaborate some more.

I am working in Access 2003.
I have set up a form that fills out my master table. What I am having an issue with is:
I have 6 different categories that different items fall under.
example: Category 58-Wire Rope and Cable
Category 60-Fasteners
Category 93 - Safety
I need each item that falls under any one of these categories to have a unique identifier starting with the category number.
Example: Safety Glass - - - part number 930001
1.5 inch Cable - - part number 580001
I want to be able to select a category from my drop down box on the form and for the part number to auto fill with the next available number in that sequence.
