how or what function (DLookup) should I use to prevent duplicate records based on multiple fields? I want to look at data in three fields that can't match existing data in those three fields. It's ok if one or two of the fields match but not all three.
View RepliesI need developing a new delete query criteria to add onto existing delete duplicate queries for deleting duplicate values. I need the new delete duplicate query to take precedent over the other two so that those values retained in the first query are kept retained after going through the second and third delete queries. Attached is a document laying out the request.

I am creating essentially a contact database; however, I want to be able to upload new groups into the database from time to time. Some people in the groups may already be listed somewhere else. If I am using an ID number to identify each separate profile; how do I prevent a duplicate profile entry? Will I have to manually check each one? Also if I use the auto-number function, how do I tell access to create a new set of numbers that are different from ones previously assigned? I anticipate about 30 separate groups adding up to around 5,000 names. I don't really care to check that many manually.

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.
1. I have a database (see attached) with three tables all of them with the same fields. The first three are numbers (InCo_No, Proto_No, Year_No). Each of these fields (numbers) can be the same in the other table(eg. Year_No), but the combination of the three cannot be.
How can I prevent the entry of a duplicate combination of these three fields?
2. I want to have a form to fill the three tables separately, depending the values in the other fields.
How can I do this?
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
I have a form (form1) that will populate with records (table1) based on key fields of "Project Number" and at time-points we will update part of the record, and then we create a word document detailing the updates with a couple of other bits of information not in original record.
Basically I want it to go from the original form (form1) into another form (form2) (via a command button) taking the key field of "Project Number" where it will ask the bits of information that we don't need have already and the contact person.
I have got this to store in a different table (table2) using a key field of just "ID" from the original records (table1). A list of contact people are in a separate table (table3) using a key field of "contact name" which will include other details for them such as address and phone number.
So from "form2" I would like to produce a report that contains information form "table1" based on the "Project Number" and "table2" based on "ID" as just been generated and "table 3" which is based on "contact name".
So I want to pull information form the records based on the certain key fields but struggling for it to pull it successfully...
Got relationships between:
"contact name" fields in both "table2" and "table3"
"project number" fields in both "table1" and table2"
In a query for the report I have all the appropriate fields, but only have the "contact name" and "project number" from "table2" is this right? or do I need both in?
Or would it be easier to draw all this information into "form2" but don't really want to select that many drop down boxes or would it be able to pull it from the "contact name" and "project number" boxes????
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....
=IIF(newEMPID=dlookup([UPDATED HEADCOUNT]![EMPID]), newEMPID, "Error, EMPID already exists")
Hi guys,
I have a question I've been trying to figure out with no luck. I have 2 fields, companyname and zip, these 2 fields may have duplicate values or they may be uniquei.e.
companyname zip
billybobs 68135
dilberts 68137
billybobs 68135
what I need to do is delete all of the duplicate records where both companyname and zip match. Is there a way I can do that with a query?
Any help is greatly appreciated
Thanks

I have a table that is going to track people. First Name, Last Name, and Date of Birth in three separate fields.I dont want to be able to add the same person in the table. How do i do this when the data is in separate fields.
View 9 Replies View RelatedDear all,
I would like to seek your help on this problem.
I would like to do a search for my records based on 2 different criterias. If found, the function should just return a boolean value so that I can act further based on the boolean value.
The reason I'm doing this is that I have 2 similar tables that contains EventID and AttendeeID and these 2 tables cannot have the same EventID and AttendeeID. So before I can allow a record to be inserted in the 1st table, it must check that there is no record in the 2nd table that has the same EventID and AttendeID. If there is, then i cannot allow the record to be inserted in the 1st table.
The same thing applies when I want to insert a record in the 2nd table. It must now check the first table.
Recordset.find seems to be only catering to 1 criteria, not 2.
Pls help. Codes are most welcome too.
Hi All,
A bit new to this, any help most appreciated.
I'm trying to set up a table which will have multiple fields (a recordset? is that right, if so I don't know how to set one up in access). Its for a skill set which is utilised by specific lines in a production plant.
Each line in the plant has a set of skills required. I have a skills table (SkillID and Skill), what I want to do is have a Skillset which I can then link to each line
So for example Skillset 1 with a SkillsetID will also have in that table skill 1, skill 2, skill 3, but all taken from the Skill table. However that would involve having the SkillID field numerous times in the same table, but this cannot be done?
The idea is that for each line I can link the Line table to the Skillset table and that tells you what skills are needed for that line.
I hope this makes sense.
Thanks all.
Hello All,
I'm trying to limit the data entered into a specifc field, but also the data must be unique with respect to other fields.
i.e.
Two fields: System A & System B.
Data entered into System A, can not be entered into System B.
Anyway to prevent this from recurring?
Would I use a validation rule?
Thanks in advance
I'm able to import new data from excel just fine, but I can't import updated data from excel due to duplicates not being allowed for a particular field. Is there a way to keep from importing duplicate records based on one field, but still import data from other fields where the information is different from the excel file?
View 5 Replies View RelatedI'm running an update query that's based on a select query (that runs some calculations). The update query is updating ALL the rows that should be updated with the information in the select query with data from the final row in the select query, and not on a per ID basis as I think I have it set-up to do. The data looks correct in the update query, but again it's not coming out right.
Here's the SQL for what I've written so far:
UPDATE [Customer_Data Query], Customer_Data INNER JOIN Baseline ON Customer_Data.ID = Baseline.ID SET Baseline.[Unit Hours] = [Customer_Data]![Dur_Days]*[Customer_Data]![Dur_Hours]*[Customer_Data]![Number_Units], Baseline.Availability = [Customer_Data]![Perceived_Avail], Baseline.[Hours Available] = [Customer_Data]![Dur_Days]*[Customer_Data]![Dur_Hours]*[Customer_Data]![Number_Units]*[Customer_Data]![Perceived_Avail],

I've also tried to force the update to the proper row by adding a criteria based on ID.
Select query, here it is:
SELECT Customer_Data.ID, Customer_Data.Data_Set_Version, Customer_Data.Number_Units, Customer_Data.Perceived_Avail, Customer_Data.MTTR_MTBF, Customer_Data.MT_TR_OR_BF_Hours, Customer_Data.Utilization, Customer_Data.Percent_Scheduled, Customer_Data.Sched_Percent_of_PM, Customer_Data.Sched_PM_Duration, Customer_Data.Sched_CBM_Duration, Customer_Data.Sched_CBM_From_PM, Customer_Data.React_Detect, Customer_Data.React_Rework, Customer_Data.React_False_Alarms,

Hi
I am writing mini database which will produce labels for boxes. I want to be able to produce a sheet of labels based on the 'number of labels' to print field. I can output one label or many on the page/s depending on how I structure the query and how many records are in the query.
My Question:
I need is a query which takes an individual record and duplicates it by the integer in the 'Number of Labels' field
any ideas?
thanks
when running the attached report I am getting duplicate records. If using the protocol specified tc02026 there should be 8 records total. When running the report it pulls from both queries which have select criteria. How do I limit the report to only give me the 8 records and eliminate the duplicates? When I run each query it only gives me the 8 records I am looking for. Each Sample# in the report is a unique number(to help see the replicates).
Thanks
I currently have a report which contains a subform. The master/child fields used to link them are called 'StudentID'.
In the table on which the subform is based, it is possible for multiple records to be associated with a single StudentID: in this case, the subform shows the locations where a student is studying, therefore if a student is based in three different locations the subform will display all three.
This seems to be resulting, when I run the master report, in three identical iterations of the same report being displayed (at least this is the only reason i can see why these duplicates would be displayed; it doesn't happen if a student only has one record in the subform).
Clearly, as a single instance of the report shows all three records in the subform anyway, I don't want to be seeing these duplicates.
I have one table like:
ID Type No
-----------------
1 FL 2
2 DL 3
I need the following table to be created using first table , each record should be duplicated according to value in No field:
ID Type No
-----------------
1 FL 2
1 FL 2
2 DL 3
2 DL 3
2 DL 3
