Validation Rule: Only Alphanumeric

Dec 14, 2007

I know that I could have done a better effort searching the forums and other places but you'd think that the answer to this would be easy: how do you set a Validation Rule for a field where a person can only enter an alphanumeric value?

I'm setting up an invoice tracking database and one of the recurring problems end users have is the inconsistent entering of an invoice number with symbols. We want to eliminate this and have them enter ONLY alphanumeric values. In other systems I've used, this has been easy to setup. But not in Access. Can someone advise? I've been trying to deal with this for two days.

Thanks...

Nov 22, 2005

Hey I have a little problem, I have this assignment for school to make a simple database, I did all that but there's one little thing I can't seem to find.
I have to limit a Field's length to 15, but not through Field Size but thanks to a validation rule, and since I don't know a lot of validation rule commands I have no idea what the syntax is for the field length. How can I do this, it's pretty urgent actually, need to have this by tomorrow :s
Thanks!

Validation Rule

Nov 27, 2005

Relatively new to access, just trying to create a range in a validation rule. What I have are 2 cells, Date_Taken and Date_Returned. I want Date_Returned to only accept values between: Date_Taken and equal to or less than the current date.

Between "Date_Taken" And <=Now()

is what I've got at the mo', yet it's not working. I'm gathering that I'm referring to the Date_Taken cell incorrectly. Any help? I don't see any tools to fix such a thing.

Hey guys, what is the easiest way to validate a field based on another.

I have 2 combo box, lets say cboOne and cboTwo. If cboOne = 1 then cboTwo must be blank/Null. Can I place this validation in the table validation properties. If so, how do I word the validation code.

Validation Rule Help

Apr 2, 2008

Hi,I'm really struggling to try and find a solution to a problem.I need to find a validation rule that only accepts:letters, spaces and hyphens (-) in the field.I have tried for at least 14 hours today and most of yesterday afternoon, but I just can't get it.The furthest I've got is rejecting everything except from letters and spaces, with each these codes individually:(I've only listed a few so you could see just a fraction of what I'd already tried)Is Null Or Not Like "*[!((a-z) or (Chr(32),Chr(45)))]*"Is Null Or Not Like "*[!((a-z) or (Chr(32)) or (Chr(45)))]*"Is Null Or Not Like "*[!((a-z) and (Chr(32)) and (Chr(45)))]*"Is Null OR Not Like "*[!((a-z) or (( ),(-)))]*"Is Null OR Not Like "*[!((a-z) or ( ) or (-)))]*"Is Null OR Not Like "*[!((a-z) and ( ) and (-)))]*"Is Null Or Not Like "*[!((a-z), ,-)]*"However, it is also rejecting hyphens, which I need it to accept.Also, unfortunately it is accepting bracketsHopefully someone here will have a solution, because I'm stumped, :confused:James

Question about validation rules. I have a user who has set up a validation rule to allow certain values to be entered.

Something like if the value equals 4 or equals 5 then it would accept it. Now she would like the validation be set so they can put both 4 and 5 in together. How can this be done?

What would be the 'validation rule' to input into the properties window for a Client ID? - (validation rule would make sure that none of the Client ID's are the same). ;)

Help With Validation Rule

May 7, 2005

Here's my problem:

Table: PARAMETERS
Field: PARM1
Field: SYMBOL

Table: TRANSACTIONS
Field: DATE
Field: AMOUNT
Field: loads more...

What I want is a validation rule on the AMOUNT field, which says that the data entered cannot be greater than the number in the PARM1 field.
I can't get this to work, and I reckon it's becuase there's one record in the PARAMETERS table, but lots in TRANSACTIONS.
In solving this problem I do not want to add any more records to PARAMETERS. The idea of that table is that it is an easy way to customise the database, not a way of storing data.
I've putting this in the validation rule box (but it didn't work):
=<Tables![PARAMETERS]![PARM1]

Please help!
Thanks

Hello can anyone help me I am trying to make a validation rule for a field. It needs to be Between 0 And 28 OR "NA". When I use this in the validation property it works for the numbers and text but if you input say NJ or any other combination it issues a message box saying cannot evaluate the constraint, check Validation rules.
Am I missing some important syntax or something. Any help gratefully appreciated.

Field 1 Field 2

therefore in field 2 12345 cannot be used again when John Doe is used in the same record.

Thanks...

Validation Rule

Apr 24, 2008

Hello All,

Here is a really simple question for someone who knows the answer, lol.

I want to enter a statement on my form that prevents the entry of specific text based on a previous entry.

For example:

One field named "Make" may have the entry "Toyota". If Toyota is typed in that field then the next field named "Model" must return an error message if someone types in Malibu.

Any suggestions?

Thanks in advance

Validation Rule

May 3, 2006

Hi,

I have one field which set the validation Rule.

Validation Rule: >0

So, the value must be greater than 0.

I enter 5, then go to next field, and then go back to change 5 to Null (blank). Then the error message come out.

I want to allow the blank in the field after I change the value.

-------------------------------------------------------------------------

I tried to use another way:
Private Sub Invnum_AfterUpdate()

If ([Invnum] <= 0) Then
MsgBox "The value must be greater than zero.", vbInformation, "Message"
[Invnum].setforce
End If
End Sub

But, it doesn't work very well, because the setforce cannot go back to the [Invnum] field. And, if close the form, it cannot hold it.

How can I control it?

Please let me know, thanks.

My Validation Rule Is Being Ignored!

Oct 25, 2006

I have set up a validation rule "Is Not Null" in the properties field of my form.

I have added validation text that I thought would appear when this rule was not met.

The field in the table is set to required "No"

I have a macro which OnClick closes the form and sends an email and when I click it, it does close the form and send the email with no regard for the fact that the field with the validation rule in is blank.

If I change the field in the table to required "Yes" I get the standard error message boxes and the form shuts itself down.

Please would somebody help me? I am a complete newbie so I need real idiot proof instructions!!

IIF In Validation Rule

Nov 18, 2011

I have a form that is used for initial entry of data as it is captured. On that form is a field called PROVCODE that is a pick-list from a provider dictionary with a bound column of the provcode value from the provdict table (e.g. - J07). On that same form a few fields down there is a DOS (date of service) text box. It is this box I want to add the validation rule to. Originally the validation rule was <=Date() so that the user couldn't enter a DOS value as a future date. Now I need to change this rule so that if the PROVCODE value is J07 that the validation rule should be (<=Date()-21) (meaning the value being entered must be at least 21 days ago in the past) otherwise is should be <=Date(). I thought it would be simple, but cannot get it to work in the Expression builder for the DOS field in the form.

Using VBA Instead Of Validation Rule?

Jul 22, 2015

I have been trying to use to a validation rule on 2 fields, and then using the OnError event to tell the program what to do if the validation rule fails. I could not get this to work and tried several different ways. I am thinking the best way to do this is to make this happen with VBA alone, and throw the validation rule from the table out.

Heres what I need to do:

I have 1 textbox in a form that needs to be monitored- MO_ID

If the user enters a number greater than 99999 and less than 999999, I need a pop up message box to appear, default the MO_ID text box to being blank, and then go to the control box MO_ID for re-entry.

Here's my best attempt at the code, but every time it sends the pop up box and never will go to the else statment, regardless of what was in the textbox:

Code:
If Me.MO_ID > 99999
MsgBox("You can not enter an employee number here!")
Me.MO_ID = ""
DoCmd.GoToControl(MO_ID)
Else
GoTo Main_Code
End If
End Sub

Validation Rule - Table

Jan 29, 2005

I have field (SupplierID) set as Text and the field limited to 5.

I want the users to enter the first three digits as text e.g "ABC" and the last 2 digits as numerics e.g "01", thus the input would be "ABC01", I can validate it to 5 digits but cannot get the validation working on the numerics, e.g users can enter "ABCDE", Am i correct in thinking its because my field is set as text ?, is there a simple way to do this, thankyou.
