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?
I have 2 comboboxes (cboTeacher1 and cboTeacher2) that should not contain the same entry and in the Property dialog box have entered "<> cboTeacher2" in the Validation Rule field for cboTeacher1 and placed "You can not have the same teacher's name in both Primary and Secondary Teacher" in the Validation Text property field.
It was brought to my attention that although it works, but apparently if you delete the value in cboTeacher1 and press tab leaving the combobox empty, the validation rule is activated and "You can not have the same teacher's name in both Primary and Secondary Teacher" is displayed.
Since cboTeacher2 is not blank, and therefore cboTeacher1 and cboTeacher2 are different in this scenario, I would have thought that the validation rule would not have displayed the message. Why is it displaying the message and how do I get it to stop if someone empties the combobox?
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 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.
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!
I have a table with the following fields:
format
region
rarity
they are all set to lookup value lists:
format: tape; dvd
region: 0;1;2;3;4;5;6;7;8;pal;ntsc
rarity: 1;2;3;4;5
I have a check that makes sure (format, rarity, region) is unique.
It works fine until i set region to either "pal" or "ntsc", then I get the following error.
"Error 'Error evaluating CHECK constraint. ' in the validation rule."
I set up the constraint by going to table design view -> indexes -> created new index with each of the three fields listed one after another -> set to primary=no, unique=yes, ignore nulls=no.
Can anyone help me work out why im getting this problem?
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.

Hello I keep getting the error after I copied a form
and saved under a different Name
++++++++++++++++++++
A problem occured while Microsoft Access was communicating with OLE Server
or ActiveX control.
There may have been an error evaluating the function , event or Macro
+++++++++++++++++++++++++
Strangely, I keep getting this error when loading
and clicking on a control in the ORIGINAL form
while the copy seems to work without errors.
I have deleted some tex box controls from the first
form and added a few new ones in the copy.
I have tried a copy of the database by deleting the
New form, but still get the same error.
I have run DEBUG on both form codes and
everything seems fine.
I have checked the refrences and find none missing.
Is there any way to resolve this issue. Or am I doing
something fundamentally wrong by copying
and modifying the form ?
I have attached the file with the two forms

Can anybody help me understand why I get the error
"Syntax error in CONSTRAINT clause"?
I get it in Access 2003 and Access 2007.
Both are clean installs with no add-ins
Running this code in VBA, or pasting the SQL directly in a query results in the same error.
Sub test()
sTableName = "Test"
sSQL = "CREATE TABLE " & sTableName & "_Config (" _
& "[idConfig] Int Primary Key," _
& "[Config] Memo," _
& "[Instrument] int," _
& "[Serial_No] Text(25)," _
& "[Firmware] int," _
& "[Orientation] int," _
& "[Sensors] int," _
& "[Sensor_Size] float," _
& "[Sensor_1_Distance] float)"
DoCmd.RunSQL sSQL
sSQL = "CREATE TABLE " & sTableName & "_Leader (" _
& "[idLeader] Int Primary Key," _
& "[idGroup] int," _
& "[idFile] int," _
& "[idConfig] int," _
& "[DateTime] DateTime," _
& "[Heading] float, [Pitch] float, [Roll] float," _
& "[Pressure] float, [Depth_BSL] float, [Height_ASB] float,"
_
& "[Min_Valid_Sensor] int, [Max_Valid_Sensor] int," _
& "[ASM_Bed_Level] float," _
& "CONSTRAINT [FK_Test_Leader_idConfig] FOREIGN KEY ([idConfig]) REFERENCES [Test_Config] ([idConfig]) ON DELETE CASCADE ON UPDATE CASCADE" _
& ")"
DoCmd.RunSQL sSQL
End Sub
The first table is created just fine.
And if I leave the constraint clause out, the second table is created also.
If I try to run it as an SQL query right in Access, after the error is delivered, it highlights the word DELETE, and if I reverse the update and delete portions, it highlights the word UPDATE.
I have looked up the clause in Access help and even using their example, i get the same error.
Any help will surely be appreciated!
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
View 14 Replies View RelatedQuestion 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). ;)
View 4 Replies View RelatedHere'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 i am new to access but i am trying my hands on it...i have a problem:i want to put some validation rule(constraints) on a field in the table such that user can only able to enter only 10 digit number and even if that number starts form "0" then it shows the starting zeros without concatenation.for ex if user put 0681482803 then it should not convert back to 681482803also one more thing i want to ask what is the best Field size for 10 digit number.. as long integer doesn't fulfill the requirement and double is very large
View 3 Replies View RelatedHi 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

I want to set that users must enter 13 numbers no more no less in form field,and if this condition is not satisfy I want to give warning to users with pop up massage.

Please help me to resolve this problem.
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,
I want to restrict data entry to a three letter code. It must be letters and not numbers. I am entering the rule at table level so that should I pass the db onto someone else the rule remains in place even if somebody creates a new user interface. Thank you
