I just need a quick, simple expression that I can copy and paste into the input mask for a control that I have on a couple of forms that prevents someone (me) to continue tabbing to the next control if the value entered is a duplicate.
I've set up a booking system and am looking to stop the system recording double bookings.
I've 3 fields, RoomID, Date and Time that need to be searched, however I can't just simply set the properties to No Duplicates (as this would mean a booking cannot be made on the same day at 9:00 and 12:00 for example).
I have a mainform (F_main) and a subform associated (F_place).
F_place is the form of the table T_place. T_place is linked to F_main by the field "BizNumber". I also have the field "Place" and of course the "Place ID" (primary key) in T_place.
"Place" in linked to a combobox (in F_place).I want to avoid, at a given "BizNumber", the same "place" to be entered in the F_place.
Im trying to prevent duplicate records based on a PO # (RA_PO_Nbr), entered from a form. I'm trying to throw a 3022 error when the user attempts to enter a record that already exists, but I dont necessarily have to do it this way.
Code: Private Sub cmdSubmit_Click() On Error GoTo cmdSubmit_Click_Error Dim db As Database Dim rst As DAO.Recordset Dim strSQL As String strSQL = "CompanyPOTable"
We are working on an Access (2007) database that is on a SharePoint Site (2007).
Currently the form is operational, but there is one last thing that would be nice to have.
The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.
In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.
All data is currently bound, so once the user makes a change it is made, no submit button is required.
We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.
TABLE - UPDATED HEADCOUNT COLUMN in UPDATED HEADCOUNT - EMPID FORM CELL user will input an EMPID - newEMPID FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID
So below is what we are trying to do, we are sure there are a few commands missing....
I would like to know what the best way to input a duplicate record is with the exception of 1 field that is used to correspond with the proper parent of the record?
Here is an example of the problem, We receive a letter with pertinent information that corresponds to 30 of our facilities. I would need to enter this 30 times so that when the users of this information run their reports for their facility I can ensure that the letter would be referenced.
I have a table for storing vehicles. The table contains the following fields:
VehicleID Make Model Trim Build Date Begin Build Date End
Vehicle Name - a concatenation of 'Make' 'Model' 'Trim' 'Build Date Begin' and 'Build Date End'
The 'Vehicle ID' is the primary key, the rest of the fields can't be indexed with no duplicates. Is there a way of preventing one from saving a duplicate VehicleName on the table since it is a calculated field.
I am putting the student names in a form. I want it to alert me that a name is duplicated. But thats not this simple. For example a name is Jennifer Locus but I type jenifer with one . Can access guess that this might be the same person and suggest me to correct the spelling or enter it as a new person?
the proper code to prevent duplicate records in my form?
I'm using:
Private Sub Ctl_Lname_BeforeUpdate(Cancel As Integer) Dim dupCount As Long dupCount = DCount("*", "Clients", "[LastName]= '" & Me.[LastName] & "'" & " And " & "[PreferredName] = '" & Me.[PreferredName] & "'") If dupCount <> 0 Then Beep MsgBox
[code]....
"This name already exists in the database. Please check that you are not entering a duplicate person before continuing.", vbOKOnly,
I have a table that contains doctor information including their license number. This came from a worksheet that tracked referrals from last season. I need a query that will show me only those record that have a unique MD License number. In other words I only need to see the 5-600 doctors out of the 2420 referrals in the table. Once I get the query of unique MD's I can create a report for the salesmen to use to contact them for the upcoming year. I know this is probably simple but I can't find the solution. Thanks in advance.
I have searched through the whole posts but could not find my query. I have a question related to prevent duplicate data entry in a form field.
I have a Form with 5 fileds on it: SNO, NAME, ROLL NO, CLASS, SECTION.
in the table design i have set the option of NO DUPLICATES on SNO(Autonumber) ROLL NO (text).
I wish to stop a user entering duplicate data in ROLL NO field before he reaches at the last field. What i meant is as soon as a user enters data in ROLL No field, it should check in table if the same data is already there. If the same data is found then it should give a message to prompt user of duplicate data, else it should continue to next field.
I have searched the whole forum but in vain. I am positive that there must be some one who holds the key to this solution.
create an expression in the Validation section to prevent duplicate entries in a field. Please view Powerpoint file on slide 1 on attachment for More detail instructions. Instructions are in simple Text and images which makes it easy to understand. I am using Access 2003.
I'm pretty new to Access, so please overlook any stupid questions :) I have a data entry form that has one field that cannot be a duplicate. So, in the table I have it Indexed with No duplicates. The problem is that the form doesn't notify the user that they have entered duplicate information until they close the form. So the 10 minutes they spent filling it out is wasted. So, after consulting various posts, I did a BeforeUpdate event with the following code: (the field that must be unique is called "LS Number", in the form "Q and D" based on the table "Q and D Database")
Private Sub LS_Number_BeforeUpdate(Cancel As Integer) On Error GoTo LS_Number_BeforeUpdate_Err
If (DLookup("[LS Number]", "Q and D Database", "[LS Number]=Forms![Q and D]![LS Number]")) Then MsgBox "The LS Number you entered already exists. Enter a unique LS Number", vbInformation, "Duplicate LS Number"
When I test this by entering a duplicate LS Number, it gives me the error "Type Mismatch." Unfortunately, I have no idea what this means, nor do I know how to fix it.
I am attempting to make a system where the lifespan of baskets in a production process can be tracked. In order to do this I am looking to create a form to input when a new basket is introduced.Each basket has a 'disc' associated with a number on (BasketNumber), however these discs are reused once the basket breaks which is making it more difficult.
I have a form (Add_New_Basket) which feeds into a table (Active_Basket); what I am trying to do is make sure that a new basket cannot be introduced with the same disc number as an active basket. The way I am trying to determine which baskets are active is that I have an end date, that is filled in once the basket has been scrapped.
Therefore I am trying to set my Add_New_Basket form to restrict me entering a new record with BasketNumber 999, if there is already a BasketNumber 999 in the table with 'EndDate' null. If there is BasketNumber 999 and EndDate is dd/mm/yyyy then it can create the entry.My form Add_New_Basket has fields ID (which is hidden), BasketNumber, StartDate (=Date()).My table has fields: ID, BasketNumber, StartDate, EndDate
I have some code which creates a record in an external csv file to provide information to upload a vehicle to the website. It works fine with the exception of creating duplicates when, for example an option to amend a record is given to the user before continuing to a new record. The option has to be in place in case there is an error in the specifics of what is important to be recorded in the database and under such circumstances the form code allows the user to tab through the form and correct any errors, but this creates duplicate entries in the csv file as the user has to pass through the 'SavePrintVehPurch_Exit' button a second time after corrections are made.
I am wondering if there is a way of altering the following code to effectively look look to see if the csv record exists and if so correct any changed field information rather than create a whole new record or create a new record where the record does not exist - The record in the csv file is determined by the 'Me.VP_VehRegMark.Value '.
Private Sub SavePrintVehPurch_Exit(Cancel As Integer) Dim fileText As String Dim fileName As String Dim fileNumber As String fileNumber = FreeFile
[Code] ....
I am wondering about introducing the something like the following ( but can't work out how to clarify comparison of the fields)
If Len(filename(fileText)) = ? Then Do not change entry Else Overwrite the new detail
If different people will be entering data into a "new donor" form, how do I keep them from adding the same person a second time?
It's possible people could have the same name, and it's possible that two people at the same address could be donors. So I assume I would want a "no duplicates" on the combination of name and address, right? But how to actually do that.
I have tried the code below, but I am not getting what I need. I have a table [Student Info] with a field [Student ID] as the primary key and many other fields. I added the Student ID field to my form, [Student Add]. When I input an ID that already exists I get an error code as expected but then my form still loads. I currently have a second form for updating student info [Student Update] for which I have a parameter form that asks for the Student ID. I would like to use just one form to add and update students if possible. So, if you add a new Student ID you can enter all pertinent data. However, if you enter a duplicate Student ID the form should populate with that student's information.
If I must have two forms (1 to add and 1 to update) and a duplicate Student ID is entered into the Add form, the user should get a message stating that the record already exists. Then, (Option 1) force the Add form to close without saving or (Option 2) give an option for opening the Update form. Either option is acceptable at this point because I am stuck.
When attempting to use the code below, I get a data mismatch error on the "Answer = DLookUp......" line.
Here's one I use on Social Security numbers for a pop up when a duplicate.... SS# is stored in table "tblApplicant"
Private Sub SocialSecurity_BeforeUpdate(Cancel As Integer) Dim Answer As Variant Answer = DLookup("[SocialSecurity]", "tblApplicant", "[SocialSecurity] = '" & Me.SocialSecurity & "'") If Not IsNull(Answer) Then MsgBox "Duplicate Social Security Number Found" & vbCrLf & "Please enter again.", vbCritical + vbOKOnly + vbDefaultButton1, "Duplicate"
Is there a way to setup the format on fields to only allow text inputs, no numbers wanted. I know I can do this at the table level but is some cases numbers are ok. So I want to code it so I can control when numbers are ok and when there not.
table name : Schedule Field 1 = Vessel code Field 2 = Voyage Field 3 = ETA Field 4 = berthed Field 5 = Sailed
there is a query by using above table and data entry form based on that query.
need to add following facilitate
While data entering, if given voyage number is already exist for the particular vessel code, msg should be pop up immediately at that time saying " This voyage number is already exist"
I would like to enter a couple of alphanumeric groups into a field on an input form. After I enter an alphanumeric group, I hit the enter and the data will add into the field and refresh to empty box ready for next entry. If I continue to enter another group and hit enter, the next group will be added to original field with a comma and a space in between. build the VBA in after update event to accomplish the task.
I need to create a field in an input form that is simply the concatenation of two other text fields. I have tried all sorts of things, but when I look at the data in the table that field.
I have a field called ID that I want to be created like this:
=Format([UniqueID],"00000") & "-" & [Mosque]
This works well in my output fields, but does not work the same way on the input form. It needs to be based on the currently input values from the current record. Anyone have any ideas?
I have a recored set and i dont want a duplicate of the record set in the same table.
