Create Random Number To Be Automatically Generated As Default Value For Record ID
May 28, 2015
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 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
I am trying to construct a system in access where I can have a user type in a part number, revision of a part, job number, serial number quantity, and generate a serial number based on the quantity that they need.
I am getting hung up on even how to construct the tables effectively to accomplish this, let alone the forms, queries, etc.
The numbers have to be in the following form. XXXX-XXXX
For an example:
I have part ABC and I need 5 serial numbers.
I need to be able to create a batch of serial numbers automagically that reads like:
9001-0001 9001-0002 9001-0003 9001-0004 9001-0005
Then for the next part XYZ I need 3 serial numbers. It would be constructed like this:
9002-0001 9002-0002 9002-0003
With the goal of eventually being able to search a part number and revision, or a job number and return all serial numbers assigned to that.
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 am using an attendance management system with a DB in Access. Now I want to create APPLICATION_ID automatically by continuing number. For example, I have a table called "LEAVE_APPLICATION" and the structure is below:
Now I want to update the table by adding the below data
00360 2 00360 2 01390 14 01390 1
How can i create the APPLICATION_ID field auto generating while pasting additional data. It should be numbering continually from the last record (Grouping to be applied for EmpID)like below:
I Have a main form called table one has 3 fields an autonumber as primary key and i have a subform called table 2 has 3 fields one an autonumber a primary key , second is an integer which is equal to table 1 primary key, and third is a text with default value set to N/A
i want when the user enter info in the main form and save it, the subform automatially add new record and save it with default settings..so far what s happening , that the related field in the subform to the main, is getting change but record is not getting save in the table 2
Hey guys.This is a real basic question but I am a newbie at this.:confused:I have created a form in Access that is actually an INVOICE for my company and therefore I have fields like [qty1],[rate1] & [amount1] In the form in [amount1] I have used the following expression to get automatically generated values.=[qty1]*[rate1]This gives me the Amount. But problem is that the result that is automatically generated by this mathematical operation is not stored in my database under the field amount1 and the field is therefore blank. I wish to use this resulted value in a report and also want to use it in other forms e.g. my sales register.kindly help me out with this.:)
I would also like to automatically attach on the server to this email. Such a file stored such as servernamesharefilename.pdf. Is it possible to do this?
Quote by Pat Hartman >>>BTW, one somewhat undesirable thing happens when you go with replication. Access changes ALL your autonumbers to random instead of sequential. That means that from that time on, all new autonumbers will be assigned randomly to minimize the problem of conflicts between the design master and replica sets. A random autonumber can range from a very small negative number to a very large positive number. These autonumbers can no longer be used as your customer numbers or order numbers if these numbers are ever printed or given to the customer to be used for reference. A customer probably will be confused by an order number = -2. If this is going to cause you a problem, you'll need to switch to custom generated numbers. Post back for details if you need them.<<<<
I'd be interested in getting some details. Data will be entering that table through a data entry form and through appending from a second copy of the DB. I want to make the PK a random autonumber but then when the second DB is added to the Master DB have the table in the Master DB assign each record a "prettier" more usable id number. I know this is stupid but I'm not sure how to relate code to a table (there's no before update event for a table as far as I'm aware).
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.
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.
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 have a database that I took over for a small group (it has about 400 records), and they want to add a field for "Member ID", to use for member badges and whatnot. A friend tried to help me by suggesting the "Change the starting value of an incrementing AutoNumber field" from the Access Help File, but I don't necessarily want incremental numbers, I just want a string of perhaps 8 numbers in no particular order, and obviously, unique to each record. I also don't understand how I can get that to work in pre-existing records...
So, what I'm wanting, in a snapshot, is: 83928475 John Smith 123 Any St 93827221 Mary Jones 678 Market St 19182734 Elvis Presley Graceland etc...
I was thinking that perhaps a formula could be created in a query? Heck I don't know! I only know enough about Access to be dangerous, so I appreciate anyone's help!
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.
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.
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)
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
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.
I m using autonumber in my ID field.My other table fields are mandatory. There is no problem when I enetered Record completely. Now if I have 20 records. automuber is also 20. Now I want to eneter new record. 21 autonumber generated. But I have not completed the form/table.or I didnt want now that record.So I didnt save it.
But next time I come autonumber 22 is generated for my new record. Now I have 1,2,3,......19,20,22,23....
here 21 has lost.Now is there any option to recover or restict that without completing the full table if the record had not saved autonumber again generated.
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.
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.
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..
