How can I make random auto numbers 8 digits in length (including leading zeros) and always positive?
Thank you
I am working on a form and need it to be able to generate a random number to use as an invoice number. The only parameters i need it to meet is that it is at least 5 digits in length. I was hoping i could use a button to make the number generate in a separate box.
View 5 Replies View RelatedHere 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.

Quick question, how do I have access generate a random number between 1 and 8? I want it to generate either a 1,2,3,4,5,6,7, or 8. (no zero, no nine)
Expr1: Fix(Rnd(8-1)*10*Rnd()) is what I have been using, but this always generates the number 2? I do want the decimals to be rounded to the nearest integer, thus I have Fix.
If someone could please help me, it would be greatly appreciated! Thanks in advance.
Hello,
I have this query:
SELECT UNIT.Code, Rnd() AS Expr1
FROM UNIT;
The problem is that in the Expr1 field all the numbers are the same. I would like to have random numbers that are different for each record (generate new random number for each record)
Thanks for your help
Cheers
Ok, I apologize in advance for my lack of knowledge but I need Help!!
I have a database form that has a O_Num field that populates the Order table. Now the client wants the order number to be a randomly generated number. this is the primary key and I cant use autonum because there is another field in the table that is autonum.
I have tried to use the following in the OnClick field, doesnt work
=Int((1000 * Rnd()) + 1)
Hello i've got to make a project for school and thought I would make a rental shop like Blockbuster. But I need to create a number that will be assigned to each customer when they become a member. So I need to generate a random number that uses a certain amount of digits (I was thinking about 8) and that won't be used again can you help.

Hi All,
I'm designing this database, in which, I have to give each record a unique random (or sequance) number of 5 digits, giving that the first digit must be retrived from another field.
Please Help, I need this ASAP!
Any help will be very much appreciated!
Thanks,
CS.
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 a log in screen that my users must use before they can use my db. if they enter the wrong username/password they get the usual message boxes. I also thought it would be a nice personal touch if once they've logged in they get a little greeting, so i made a message box that says "Hello " followed by their first name
This did the trick for a while, however theyre sick of seeing "Hello" and want other greetings, i figured this wouldnt be too complicated and took me only about 10 minutes or so to implement.
Basically i created a table (tblGreetings), has two fields, an autonumber field (ID) and a short text field
I've added the following code into the login sequence:
Dim greetings As Integer
Dim greet As String
Dim randomNum
greetings = DCount("ID", "tblGreetings")
randomNum= Int((greetings - 1 + 1) * Rnd + 1)
greet = DLookup("Greeting", "tblGreetings", "[ID]=" & randomNum)
which in theory should generate a random number between 1 and "greetings" (which is an integer representing the number of greetings ive stored in my table), currently greetings=9
then it should pick a greeting from tblGreetings using the random number as an ID
This more or less works, except whenever the DB is opened and a user logs in, the "random" number is the same every time, it always seems to be 7 (which corresponds to the greeting "G'day").
Why this random number is always the same? it changes if i run the code a few times in the same session, but once the database is closed and reopened it still gives off the number 7, every time
On an Access database, I would like an ID number to be generated randomly.
This ID number needs to be within the range of 11000 - 99999.
How is this possible?
My company does daily, weekly, and monthly drawings using mountains of entry tickets and a barrel that has seen better days. So needless to say this system has to go. I hope to be able to do it digitally.
I would like to do a random number generator to pick the winners based off of a ticket number range. The ticket numbers issued to the customer would correspond to the customer account number. To complicate things I would really love to have the random numbers displayed on the screen so people feel they are watching the randomization pick in progress with the winner name popping up.
I have searched Help for Rnd function, as well as googled. I haven had any luck finding what I need. Is what I am looking to do possible in access? I had something similar in Excel a few years ago but lost it.
hello all
I am trying to set column values to a random number between 3 and 5
PMRatingTokenID: textH1: doubleYearID: textCode:UPDATE PMRating SET PMRating.H1 = (5+3-3)*Rnd()+3
This shows type mismatch error . What is the problem here..
please do help...Thank you
Hi.
I have major report due within hours.
I need to add a field to existing table that will be a 9 digit number, non duoplicating or - to take an existing field of 9 digits and allow it's values to change to random or incremental, non-duplicate numbers of 9 digits. I already have an autonumber field I must keep.

I have a RN generator that looks at 9 different lanes and puts in a number based off of a certain criteria but I was wondering if in the frmLanes the actual "Go" button was an incoming number how could I get my current random number generator to look at that number and determine if the current number is within 5 of the "go" number?
Any way to have a beginning number that I would enter into a text box and have the number generator kick off based off of that number. I have included a copy of my db for viewing.
I have a form which allows the user to add new records to a table. After the user had entered all the information into the form, they click a command button to add the record. In addition to adding the new record, my command button runs an query which is supposed to generate a random number between 1 & 1,000,000,000 and update the record ID field with that number.
Here is the formula I have been using in the "update To" now of my query: Int((1000000000-1+1)*Rnd()+1)
My problem is that I keep getting duplicates. You would think that the chances of getting a duplicate number would be pretty small with this large of a range, but I get a duplicate almost every time.
I have tried indexing (No duplicates) the field in the table, but that did not work. When my query generated a duplicate number, the record was just not added to the table.
I also tried a two step approach:
1-Make a table of all in use record ID numbers from my table (tblIdNo)
2-Update new record with a random number that is not in tblIdNo
This was a no-go too
How to build an update query that will update each new record added to the table with a random number between 1 & 1,000,000,000 without any duplicates? This seems like it should be so simple, and I am starting to get really frustrated.
I would prefer to accomplish this through a query/queries (if possible) rather than with 100 lines of code. This database is not for me, it's for another group, and the individuals in this group are totally freaked out by code.
I'm trying to create a query that generates random numbers for each record, sorts them by that field, then selects the top record. This should randomize the record being selected.
I can use the Rnd([ID]) function which does appear to generate a random number. Problem is that each time I exit the program and come back in, it always selects the same record. When I remove the Top = 1, to show all the records, every row does have a different random number but it does not appear to be sorting by this field.
If I run the query, here is the number I get: 0.98609316349029
Exit the program, restart, and run the query again: 0.98609316349029
If I refresh the query, the second and third time does appear to be random but the first result is always the same. how to generate truly random numbers?
I've been building a CRM in Access that allows for creating profiles for our accounts. When we add a new account, I'd like an Account ID to automatically generate and look like this: CRMXXXXX where the X's represent a random number. I originally wanted to set the field as autonumber to just count up, but unfortunately I need to append this value to another sales database we have; you can't store the text "CRM" with an autonumber in a table.
Right now, all I've done is place an equation in the default value of a textbox I have on my 'Add Account' form. I then made the control source of the text box the Account ID field. My equation is as follows:
="CRM" & CStr(Int(Rnd(Now())*10000))
This appears to work, as it generates a value in the correct format. However, I've realized that each time I open the CRM, the random numbers start over again and I run into issues of trying to create a new record with the same ID as a previously created record. I assume I need to incorporate some sort of timestamp to it in order to change it.
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.
I would like to know if there is any procedure to restrict/stop auto number increment for certain number of record count (say 50), then increment by 1 for next 50 records.

More specifically - random long integers linking back to an ID (autonumber) field in another table?
Background to this is, I have multiple static data tables related to each other by long integer identifiers (autonumbers)
The structure is fine but I haven't been provided with the actual data yet - but for development purposes, I need to work on other functionality which requires that this data be present.
So I want to fill my table with dummy data such that I can go off and work on the remaining functionality, but then just go back and clear it all out once I get the actual data.
I have one 'main' static table, which links back to other tables, which I have already populated with dummy static (i.e. company names, locations etc) Now I want to go into my main table and populate those fields in each record with a random ID. I don't mind doing this field-by-field (there's only a handful) but I've a lot of records in there (~1000) so I'd rather not do this record-by-record.
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!
I'm trying to get an invoice number field to auto generate the next number, keeping the format as "00000"...this is what I have, which gets the next number but drops the leading 0
Code:
Private Sub Customer_AfterUpdate()
If Len(Me.[InvoiceNumber] & vbNullString) = 0 Then
Me.[InvoiceNumber] = (DMax("[InvoiceNumber]", "[tblInvoiceNumber]") + 1)
DoCmd.RunCommand acCmdSaveRecord
End If
End Sub
invoice numbers are 04024, 04025 etc...how I keep the formatiing?
I need to create an auto number for service calls that show the following:
year as 08, 09 etc, month as a letter, Jan = A, Feb = B etc then an incremental number starting at 300 for each month/year combination.
So for example: 08A300
Can anyone help me as I am stuck?
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 ?
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.)
