Prevent Duplicates In Reports
Jun 5, 2006
Help! I'm on of those home grown programmers. I have the report all ready to go. Four columns with data from a table. The 4th column is showing duplicates that I would prefer just show up as blanks. Following the 'help' screen I changed the preferences for that box to HIDE DUPLICATES: YES. The help screen says this should work exactly as I hoped, but when I run the report every field is populated.
Any ideas??? I'm sure there is some small config change but It is beyond me.
Thanks,
t.

Hi,
I have created a database that monitors containers that are being hired. When a container is hired some details are entered and remains the same until we receive an invoice to state that the hire has stopped. Subsequently, the database is updated and an invoice sent. The container is then hired out again and some details are entered on the database and so on.
There are two check boxes to state whether the container hire has been completed and whether the client has been invoiced.
I am attempting to stop duplicate entries of container numbers being entered onto the database when the transactions are not complete and the client has not been invoiced.
I cannot use a primary key because the containers are reused and hence the container number will be on the field more than once. I have also tried a find duplicates query, but this found duplicates in the whole table and returned only the duplicates that were in the criteria I had specified.
Basically, I want the validation or whatever to prevent duplicates only when the two check boxes are 0.
Thanks in anticipation for your help.
All the best,
Roly

I have a form with a text box called txtID. When the user types a value in the text box I want it to check if the value already exists in the field ID in table "Headcount" (a linked table from SharePoint). If it does, then I want a pop up box to display with error. Is this a Dlookup function?
I've tried DCount but can't get that to work.

Attached is my many to many relationship setup. I would like to prevent the possibility of entering the same person more than once for the same training event. I am assuming that I do this by setting an index setting for a field the junction table?

I have a Composite Index to prevent duplicates I get the error message. How can I trap this?
I resolved it with this PHP Code:
'Trap Error.
Dim DataErr As Integer
Dim Response As Integer
Dim Message As String
If DataErr = 3022 Then 'Duplicate value entered
Response = acDataErrContinue
End If

I have a client database that has recently had multiple duplicate entries. I need to reduce or negate this erroneous activity. I have a client table where I record amongst others, the following;
key
[christian_name]
[family_name]
[dob]
......
I believe that to prevent duplicate entrie via form I have created an additional field called "unique" given it as a unique index which I want to have populated with the joined fields first_name & last_name & dob (IE johndoe01/01/90), and then as user enters a new client it wont allow a duplicate.
However I need to fill all the existing customers (3600+) with the relevant joined existing data. If I create an expression I can cajoin the fields in a select query but when I try to make an update query the same syntax comes up with empty fields.
select query sql that worked to show field ...
SELECT divers.christian_name, divers.family_name, divers.dob, [christian_name] & [family_name] & [dob] AS Expr1
FROM divers;
update query that was empty ..
UPDATE divers SET divers.[unique] = [christian_name] & [family_name] & [dob];

I'm in Access 2013 and I built a form with multiple drop downs. Here is what I have in the same order of which the user must choose from......
Document "Field Observation", "Monthly Inspection", "Safety Roster" (The user must first choose the document from this drop down he is recording)
Supervisor "First & Last Name" (The user then chooses the first & last name of the specific Supervisor name he is recording the document for from this drop down)
Manager - This field automatically populates based on Supervisor.
AOR - This field automatically populates based on Supervisor.
Org Unit - This field automatically populates based on Supervisor.
Month "January", "February", etc. (The user then chooses the Month of which the document will need to be applied to)
I would like the form to trigger an error with "This document is already recorded for this month" when the user chooses "Monthly Inspection" OR "Safety Roster" for a specific "Supervisor" for a specific "Month" that is already recorded in "TBL_DataTracker". The TBL_DataTracker is where all of my records are stored.

I have come across this problem several times. I have sub reports on a report and calculations are done using the data in the sub report. In many instances the subreport is empty. The calculated fields read #error. (otherwise the report runs well and records with data calculate fine) I would like to hide these errors and associated labels when the subreport is empty. Everything I have tried either does nothing (error still appears in text box - but runs ok otherwise) or I get a runtime error since it is trying to access "nothing" in the sub report.
How can I catch and therefore react on this empty sub report. (or subform too)
Thanks
Lisa

I have a report that comes from a query.
On the report I use the group function on a field called assemble part number and select no duplicates in the property field . so I don't get that part number on every line below that group.
When I print the report it gives me the assembly part number on every line can the report be printed without it on every line just the group line.

In access database we register the following fields:
Company name - Address - Artickle - Number of copies
We then want access to print a report with these informations, except for the number of copies, which should be the number of duplicates that is to be printed.

Hey, all! Thanks for helping, here is my situation.
I have a table with about 70,000 records that have duplicate Address field values. The rest of the field values for those records are different. When I do a find duplicate querry I get the result that 17,000 records have the same address. However, when I do the append qurrey as instructed here: http://support.microsoft.com/?kbid=209183 I get a total of only 600 records in the new table. I have tried deleting all of the indexes for both the new and old table, with no luck.
I'm using Access 2000 on XP Pro.
If anyone could help with this I would greatly appreciate it!
Thanks
Will

I have an Access table with an indexed key that is currently set to duplicates OK. There are not supposed to be any duplicates in that field. But it is possible than a small number have crept through.
Two questions:
1. What would happen to those duplicate records if I changed the setting from duplicates OK to no duplicates?
2. Is there any way to ferret out those duplicate records first and change them manually? The table currently has 48000 records so it would be a pain to go through them page by page. (I know how to export them to Excel, where the dups can easily be found; I was just wondering if something could do it within Access.)

I managed to corrupt a database. I think I did this by accidentally creating a module that had no info in it and was never complied.
The day before, I had made several table additions and had run compact and repair twice at the end of the day and all seemed well until the next time the database was opened. Does this make sense that an empty module caused the corruption? I'm asking so that I know how to avoid future mishaps. I'm using Access 2000. Is 2003 less likely to corrupt?
The database was running from my hard drive at the time, so it wouldn't have been a sharing violation.
I think I'll be able to get everything back by importing the objects into a new db.
Thanks,
Mary

I am doing more and more Access projects at work. I am using Access 2003. Is there a way I can prevent people from tampering with what I give them? I always create an autoexec macro and run "Windows Hide", then open the main form. Someone can easily unhide the window or hold down the shift key while opening the file, then tamper with what I have put together. Is there an simple and easy way I can prevent tampering?
Thanks,
Jim

I am a school nurse. I have started to keep a record of office visits of all the kids that come to my office in a MS Access database. I have a table that I use for logging in each student, time, date, reason for visit, action taken, etc. along with a lot of other info on other tables and queries. I'm wondering how to keep the data entered on the health office log from being altered once entered. Is there a way to do this in Access? Thanks

Hi,
Does anyone have any ideas on how I might prevent a database from being copied. I have an application that I have set up with a number a tools to prevent exporting to an empty Access container, and from accessing the database design via the ShiftBypass feature, but the database can still be copied in its entirety. In some situations I would like to be able to add a feature to prevent this. Any suggestions?

Hi,
I created the database, which shared by multi-user. But, my user have a problem to open it. When user1 open the database, user2 cannot open it, I did not remember the error message, it is said that Admin (computer name) prevent you to open the database. But, if the user1 switch another application program (the database file is still opened), user2 can open the database, then both users can access the same database file.
Why do we have this problem? How can I fix it?

Hi!
I'm working on a Access 2003 mdb file. I want the database to start commonly without any user-login screen.
Nevertheless I want to prevent the default logged in user from making any changes to the database structure, using the tables and examing the VBA code.
Because of some strange guidelines I have to respect those changes have to be directly made to the mdb file itself (if possible) so no additional worgroup file is created.
Is it possible to realize it that way?
Thanks!

What is the best way to prevent widowed records? By widow record I mean records in the parent table that do not have a related record in the child table.
I have a tblOrder that is linked to a tblProductOrder by the OrderID field. I don't want the user to be able to create a record in tblOrder without adding some products to the order, which will be stored in tblProductOrder.
Thanks for the help.

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).
How can I do this?

Dim Db As DAO.Database
Dim rs As DAO.Recordset
Dim f As Form
Dim MthYr As String
Set f = Forms!frmQpi
MthYr = f("txtMthYr")
sql = "SELECT * FROM [tblQpiMonthly] WHERE (([tblQpiMonthly].[Input MthYr] = 'MthYr' ));"
Set Db = CurrentDb()
Set rs = Db.OpenRecordset(sql)
If rs.RecordCount = 0 Then
If (f!txtTotalPF) = 0 Then
Exit Sub
End If
rs.AddNew
rs![Input MthYr] = f("txtMthYr")
rs![Monthly TotalPF] = f("txtTotalPF")
rs![Monthly Rejection] = f("txtTotalAvoid")
rs![Monthly TotalAvoid] = f("txtRejection")
rs.Update
Else
If (f!txtTotalPF) = 0 Then
rs.Delete
Exit Sub
End If
