Forms :: IS NOT NULL Not Working In Control Validation Rule
Apr 15, 2014
I am using Access 2010 on Windows 7 (64-bit).
I have create a table clients that contains multiple column i.e. Id, First Name, Last Name, Starting Date, Company , while defining the table I did not mark REQUIRED property of any column
I have created a form based on this table "CLIENTS",
I create the company as combo box and taking the list from COMPANIES.ID
I put the validation rule as IS NOT NULL and put validating text Select Company from list.
If I marked REQUIRED property of this column in table definition as YES then it displays system generated message with tablename.controlname, while i want to display my own message.
But when i input the data and leave the Company column blank the validation is not executed.
There are three columns in the form on which I want to apply the same validation.

TextBox1 Validation Rule is
>=0 And <21
I would like to replace the error message
" The value you entered doesn't meet the validation rule...."
I made a start with the OnUpdate Event
If Me.TextBox1 <= 1 Then
Msgbox "Whoops..."
Else
End If
But, although my message box appears, (nothing else does) the Validation Rule is ignorred and then zero entry causes an error.
So, I'm guessing, my If Statement has to catch the whole Validation (somehow). Am I on the right lines?

I have a main form which has couple of subforms bound to one main table. One of the subfomrs is about employment info. It has 3 TextBoxes: (Job Start Date), (Employer Name), and (Wage).
It has also 3 ComboBoxes: (Job Type [Full Time or Part Time]), (Hire Status [Permanent or Temporary]), (Quarter [1st, 2nd, or 3rd]).
I want to force users to fill all these 6 fields if they put any value in any one of them. I tried to set a Validation Rule in the TextBox/ComboBox’s property including IIF statement condition, but I did not succeed, and these rules did not work.I put the following code in the subform’s (After Update), (Before Update), and (On Current) events which works very well when I keep the (Wage) value 0 and move to a new record or to another subform:
Private Sub Form_AfterUpdate()
If Me.[Start Date] > 0 And Me.Wage.Value = 0 Then
MsgBox "You did not put how much is the wage."
Cancel = True
End If
End Sub
[code]....
how to make a similar validation rule for the other TextBoxes and ComboBoxes.

Can't we give conditions on Validation Rules? (Like IIf)
IIf(getusername()=[Log_Resource],Between DateAdd("d",-1,Date()) And Date(),Between DateAdd("d",-2,Date()) And Date())

I am trying to create a validation rule whereby If a box is checked it makes sure that before saving and moving to the next form several, though not all fields are valid.
Ive tried many variations of:
([x] Is Not Null) OR ([Y] is Null) And ([x] Is Not Null) OR ([Y] is Null] etc etc for the fields I need covered.
Either the rule doesnt work at all or else all data input is invalid!

Is there a way to add a validation rule in an access form on an unbound text box. This box is currently doing a calculation of others. If the figure is not between 0 And 0.3125 then I do not want the user to be able to move on. For some reason if I enter "Between 0 And 0.3125" in the validation rule it doesn't seem to do anything. I can only assume its because its an unbound text box. Data attached please see Frm_Input and text box total standard hours.

Error: Error evaluating check constraint in the validation rule
What does this mean?
I have used a combo box in the table to input into 2 fields - one restricted to numbers 1 to 5 and the other restricted to letters A to E
Message comes up when I try to change the view or press submit. Does it have anything to do with the field type?

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!

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.

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). ;)

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

Hi all,
I have a form that records a unique number which requires a full stop to be present. Is there anyway of ensuring a user has to enter a "." somewhere in this box?
Cheers:p

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.

How do I set up a validation rule for a table where the rule checks two fields to see if combined they are unique...i.e.
Field 1 Field 2
John Doe 12345
therefore in field 2 12345 cannot be used again when John Doe is used in the same record.
Thanks...

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

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.

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!!

Both Reorder Quantity and Reorder Point are table fields.
If I am going to create a validation rule:
Reorder Quantity cannot be more than twice the reorder Point. How am I going to do this?
I tried:
< 2*[ReorderPoint]
but it didnt work. Please advice

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.
