General :: Generating Random Project Numbers With Date
Jun 7, 2012
How to generate random project numbers that reset automatically every month? I want to generate project numbers that look like this:
1234/06/12
where the 06/12 stands for the month and the year while the 1234 is a randomly generated number.
I want the random number to be four digits long.
I already have a number of projects with similarly generated projects from an existing database. Can I import these projects without changing their project number?

Hi Guys,
In my table design view I've set my primary key to auto number and the 'New Values' to random. The problem is, sometimes the numbers generated are too long or negitive. Is there any way I can specify the limit of the numbers to be generated and keep them positive numbers?

I am trying to create a database to link to an online auction site (not ebay) and I want to create a query that randomly generates auction end time and auction length for all listings. I have tried int(rnd()) and various versions but can only generate the same number for all fields in the query.

hi,
I have a table that has results from races, eg.
Race No, Racer ID, Time taken.
i want to have a position field that will say which position the runner finished in. This is complecated as there are many different races.
At the moment the best thing ive been able to do is set up a query with a parameter on the race no. then the time taken is put in order and i have to manually put in the positions.
Manual is bad!
does any one have any idea about how i could make this automatic.
Thanx,
MAtt

I've searched through the forum looking for what i want to do with no luck so hopefully one of you kind people could help.
I'm setting up a DB that logs in a batch of parts to which i generate a batch no.
As the batch progressess through the works when a problem arises we generate fault records (I've set up another table for this and linked the batch no fields together). I want to put a serial no. on this form consisting of 'year' 'batch No.' and ?'Auto number'? From reading posts is it best to put the 3 items in seperate fields (less hassle)
My 2 questions are
1, how do i extract just the year from a date field?
2, This is the main problem. The auto number. If i use auto number to generate a unique number to log the record the number will be massive in no time at all. This is fine as the unique identifier for the record in a table but not for the serial number of the printed report. Idealy I want to have the batch number then a serial number that resets to 1 on a different batch No. For example
21098/1
21098/2 Batch No./serial No.
21098/3
22309/1
22309/2
22309/3
Just some more info this database is a multi user database split front and rear.
I hope i've explained this well enough, many thanks for your help in advance
cheers

Hi,
Can you please help me out--give me some guidance-if you have knowledge about random numbers. Say, for instance, I have 2,000 records and I want to randomly create a final list with 800 of these records, how do I go about it? Thanks.

I'm building a database for my folks's volkswagen car show (www.texasvwclassic.com) if anyones interested ;)
So I've got a Registrations table and a Classes table. Each person that registers for the show is an entry in the Registrations table, and a field in that table is Class, with a relationship to the Classes table. That is all set up and working fine, but I want to add an EntryNumber field generated at time of checkin, so some VB function I can call when the checkbox is clicked in the form, or a query based off the value of the checkedIn field. I want the EntryNumber field to contain a number like 0503 (CCNN) where CC is the class number (class #5) and NN is a counter of how many people have checked in so far in that class (so 0503 would be the 3rd person to check in for class #5). I can get the class number fine, and I can prolly figure out how to stick em together into another field, but im not sure how to generate the NN part.
In the classes table, each class has a sub-table listing all the registrations that have entered that class. I need like an autonumber field in each of those subtables, but I dont understand how to add something like that.
I hope this makes sense, as always any help is appreciated. =)

Hello Everyone,
Im trying to make a query which will allow me to run a query update so that all my listings will get a new random number generated for them,
Ive got it selecting any listing with a ID of >0 (so basically thats all of the listings)
What id like it to do is then assign a random number to the randsort field, (prefer a number like 0.812 or 0.342 etc etc)
To start with ive tried using the Rnd feature, but its updating all the listings with exactly the same number (though granted the number changes each time the query is run)
I see in some of the other comments regarding rnd that you may need to put a randomize statement somewhere,
Im very new to programming in access and was just wondering am I on the right track, and if so where abouts should i declare the randomize code since its in a query?
Thanks for your time and look forward to your replies
Cheers Ezy

I'm reworking a db to make it web compatible. Right now I'm working on my Price and Sales tables.There are about 900 Sales records, 450 Price records (for about 45 Items).
I have re-done my Price table with an Autonumber Key field. (It had a multi-key which I understand web db does not support.) Each autonumber key represents a Date with new Price for a Company/Item. The Price change Dates are random.
I have put a Foreign Field in my Sales table for the Price key field.
My dilemma is matching the Sales with the Prices.
When the Price Date and Sales Date do not match (at least half of them don't match), I need to look back in the Price table to the max Date BEFORE the Sales Date in the Sales table for that Company/Item in order to select the correct Price key.

I am using the following expression to calculate a completion date for a project which is based on the due date. My problem that I am running into is when I get to a project that is due on a Tuesday, it returns a date for Sunday when it should be Friday.
IIf(Weekday([Due Date])=2,DateAdd("d",-4,[Due Date]),DateAdd("d",-2,[Due Date]))

When I create a new record I am also generating a new Auto Number. This is so I have a sure fire way of returning the records that I want to return. I have read where it is a known issue that when using the Compact and Repair it can reset the Auto Number to a lower number and generate a duplicate Auto Number. That is the problem that I have at this time. I have tried using the Allen code but it doesn't seem to worked on linked tables. I use linked tables because I have multiple users who can access this system at any given point in time.how to have the Auto Number field select a number that is unique

I'm sure it's not random, but it doesn't seem to follow any sort of rules. My database has become "Read Only" 3 times now causing all workers using the database to stop work until IT can fix the issue. All IT does is kick everyone out of the folder that my db is in and suddenly it is no longer read only.

Anyway, here is what I am looking to do:
1.) Generate a random number between 1 and 100 and assign the result an identifier, like a person's name.
2.) Generate a second random number between 1 and 100 and assign the result a different identifier, like another person's name.
3.) Compare the two randomly generated numbers.
4.) Have the identifier of the LARGER random number displayed on the screen.
I would like to have this linked into a button click.I am hoping there is an easy way to accomplish this task.

I have almost all of my info with the exception of few hundred pieces of data entered into my database. After looking it over and looking for ways to improve it, would it be easier to import all the tables into a brand new database and starting fresh with everything? I have made a lot of changes since the inception of the database so there are forms and queries and reports that no longer work because of the changes. Or should I go back and change them?
Also, if I am looking to join to tables can they be joined by their foreign keys? They are listed below:
tblEmpInfo
EmpInfoID <PK>
EmpIDFK <FK>
JobNumberFK (joined to tblJobs)
EmpType
CraftCode (would get rid of this)
tblEmpRating
EmpRatingID <PK>
EmpID <FK>
EvalDate
SuptID
StatusChange
CraftCode
I want to join the tables based on the EmpID can this be done or do I have to add another field to EmpRating ID?

I have a large table with a number of fields. I have written the query that I want but can't quite work out how to get it to do the main thing I need. I have several fields that I need to generate in the report but what I want it based on is the field called Date Approved.
When the Date Approved has been Active for more than 4 weeks I want to pick it up in the report. I don't want to set a date to start from but pick up everything that has passed 4 weeks in "Date Approved".

I pulled a report from this website my company uses and it has around 7,000 orders and a corresponding employee to each record. Since each employee has around 20-50 orders, I was wondering if there was a VBA code or different Access tool to randomly select only 2 orders from each employee, thus reducing the data set from 7,000 to a more manageable number?

The Str() function is a basic, how can this function be missing? I had a problem not so long ago with not being able to change background colors via VBA 'cause, I'm almost certain, the same error message.
Somehow my Access installation is broken, or my HD is dying? Haven't noticed any other errors with my system though.

Am just trying to set the default value (on the form, not programmatically) of a text box to a date but with every attempt it either fails or sets the date to 1905-randmon month & random day.I've tried a few different methods from various online sources.
=Now() works fine.
Any attempt to set to an actual date returns 1905-Random Month-Random Day?I am trying to set it to the 1st day of the current month.Text Box is formatted as Short Date - Regional settings are set to the ISO standard numeric date format YYYY-MM-DD.

I have a query regarding signing my database. I have purchased a code signing certificate from Comodo. I have signed the VBA project and then set users security to 'Only enabled macros which are digitally signed' but when the database is opened it still gives the prompt 'Some active content has been disabled' and the user has to click 'Enable Content'.
Why does Access decide it should still disable the content when it is signed?

How do I print the complete code of a project? If I select all the code with CTRL+A in the code window does it print all the objects of the project I'm in or I have to select each object from the drop down list at the top of the code window?
