Modules & VBA :: Sequential Numbering Dcount Dmax Composite Primary Key
Sep 23, 2014
I have a question concerning the automatically sequential numbering of a primary key as part of a composite primary key.
Tbl_treatment:
ID=numeric field (also in tbl_pt and in tbl_tumor)
Tumornr=numeric field (also in tbl_tumor)
Treatmentnr=numeric field
[ID] and [tumornr] are fixed and i would like to automatically number [treatmentnr] per [ID] AND [tumornr] in a way that the output will look like this:
1001 1 1
1001 1 2
1001 1 3
1001 2 1
1001 2 2
1001 3 1, etcetera.
However, when i use the SQL-formula below my output looks like this. It seems as if the function is not properly taking the composite primary key of [ID] AND [tumornr] into account or not finding the true max value:
1001 1 1
1001 1 2
1001 1 3
1001 2 2
1001 2 3
1001 3 3, etcetera.
If (DCount("[treatmentnr]", "Tbl_treatment", "[ID] = " & Me.ID & "" & "AND [tumornr] = " & Me.tumornr & "")) = 0 Then Me.treatmentnr = fRowNum(False)
Else Me.treatmentnr = (DMax("[treatmentnr]", "Tbl_treatment", "[ID] = " & Me.ID & "" & "AND [tumornr] = " & Me.tumornr & "")) + 1

I have column called "order" in table called "mov" and this column has this layout
Code:
1
2
14
255
222
1755
12
And I want to update this column to be corrected numbering from 1 to the last cell number - lets say it 17540 - this update has no criteria conditions, just this field.

Hello Access friends,
Trying to have a sequential autonumber for the ScreenID with the DMax () function.
Please advise on what is wrong with the following :
=Nz(DMax("[ScreenID]","[Screenprep]","[ScreenID] = '" & [CarModel] & "-" & Left$([Category],1) & "'")+1,0)
Neither putting this code in control source or beforeupdate event of the form is not working.
I have looked around and from previous posts in the forum come up with this module. But it is not working either:
Public Function NewScreenID() As String
Dim db As DAO.Database
Dim rst As DAO.Recordset
Dim ScreenID As String
Dim CarModel As String
Dim Category As String
On Error GoTo Err_Execute
Set db = CurrentDb()
Set rst = CurrentDb.OpenRecordset("SELECT Max([Screenprep].[ScreenID]) AS MaxScreenID from [Screenprep];", dbOpenSnapshot)
If IsNull(rst!MaxScreenID) Then
NewScreenID = [CarModel] & "-" & Left$([Category], 1) & Format(1, "0000")
Else
NewScreenID = rst!MaxScreenID + 1
End If
rst.Close
Set rst = Nothing
Set db = Nothing
NewScreenID = ScreenID
Exit Function
Err_Execute:
'An error occurred, return blank string
NewScreenID = ""
MsgBox "An error occurred while trying to determine the next sequential number to assign."
End Function
In advance thank you for your time.Can someone please guide me on how to sort this out?

I'm using the following code to generate a sequential number"
Code:
Private Sub Form_Load()
Me.txtReceivedDate = Now()
'assign an EmailID when form loads
Dim CurMax As Long
Dim NewMax As Long
'poll the current EmailIDs for the largest number from current year and add 1
[Code] ....
Until recently, I didn't have any criteria on the DMax and it worked perfectly. It's now been decided that the EmailID should reset back to 1 when the calendar year changes.*
*EmailID is not my primary key - There is a separate autonumber field used as the primary key.
The table I'm using the DMax on has a field named ReceivedDate which stores a Now() when a record is created. The form I'm working in has a textbox named txtReceivedDate that is set to Now() when the form loads as can be seen in the code above.
What I'm trying to use as my criteria in the DMax is to match the Year() of ReceivedDate in tblEmails to the Year() of txtReceivedDate on the form.
For 2013, the current max (CurMax) EmailID is 21. If I set my computers date back to 2012 (where the CurMax is 3) the txtEmailID is still being populated with 22, even though txtReceivedDate shows a 2012 date.
I've tried a handful of permutations of the criteria string:
Code:
Year([ReceivedDate]) & " = " & Year(Forms!frmNewEmail!txtReceivedDate)
Year([ReceivedDate]) & "=" & Year(Forms!frmNewEmail!txtReceivedDate)
Year([ReceivedDate]) = Year(Forms!frmNewEmail!txtReceivedDate)
I've tried a few others long the way that I don't even remember, but there's probably little value in listing all the ways that don't work.
I've got a syntax issue within the criteria since it's the first time I've tried to use one and it contains a couple moving parts.
Once I get this sorted out a follow on question is about dealing with the users changing the txtReceivedDate to a different year. As of now, I have the same code (everything except "Me.txtReceivedDate = Now()") also present in txtReceivedDate_LostFocus(), but I'm not sure that's the best place for it.

Shall be grateful for clarifications for these two :
1. I have two fields - TheYear (set to take the current year) and another for sequential numbering. In fact I created this to replace the autonumber field. As suggested by a member I created a Generate button with the criteria as under
Private Sub Generate_Click()
If IsNull(Me![NumFld]) Then
Me![NumFld] = Format(Nz(DMax("[NumFld]", "[DiaryTable]", "[TheYear]='" & Year(Date) & "'"), 0) + 1, "00000")
End If
Me![NumFld] = Format([NumFld], "00000")
End Sub
It works fine. and when the year is changed, the numbering starts from 1 again. My question is how do I make it to auto generate the number so that the user doesnt have to click the Generate button everytime to get the number. Suggestions please.
2. Is it possible to change this sequential numbering midway i.e. to start from a different number and increment by one?
Grateful for help

I have an existing table with a field labelled Job Number (17 Job Numbers). Each month I import a new table and match each record via another field (serial number). For each new record, one or many, I want to attach a sequential Job Number. In this example the new job numbers need to start at 18 then 19 etc. How is this possible? I am fairly new to Access so please be gentle!. Cheers

Hi all,
Simple question (I hope)...
Need to devise a way of updating a field with an ascending sequential number within a group of records of similar type.
e.g.
Say I have records which consists of numerous IDs and various job descriptions within the each ID
13000 Head of Maths 1
13000 School Secretary 1
13000 Head of Maths 2
13000 Head of Maths 3
13000 School Secretary 2
14000 Head of Maths 1
So in this case each 'Head of Maths' and 'School Secretary' sequentially increments until there is a new ID.
Any help appreciated.
thanks,
Alex

I need to generate line numbers for an access query. This query is run via VB code. After it runs, a Dlookup is performed to search for the line number of a particular order detail id. When it finds it, it puts the line number along with other unique order detail information into a text file to be used by a computerized saw that cuts the parts out. Here's a sample query:
DetailID SortID Frmlgnth Stilelgnth OrderID SeqNo
1874864127.12511.9375160004
1874866127.1259.6875160006
1874868127.1258.5160008
1874869127.1255.8125160009
1874867111.8758.8125160007
1874863110.12514.875160003
1874865110.12510.5625160005
1874871221.62514.3751600011
1874872221.62513.81251600012
1874873221.62513.56251600013
1874875221.62511.68751600015
1874876221.62511.6251600016
1874877221.62511.06251600017
1874870221.2516.31251600010
1874874219.12511.751600014
1874878219.12510.251600018
1874879219.1257.1251600019
1874862534.5103.375160002
1874861534.536.875160001
The query is supposed to be sorted with SortID Descending, Frmlgth Ascending, Stilelgth Ascending - in that order. The sort is working fine. However, the Sequential numbering is not. The OrderdetailID has NO bearing on the sort order. Here is my SQL code:
SELECT OrderDetails.OrderDetailID, ProductTypes.ProductTypeSortOrder, OrderDetails.FrameStileLengthActual, OrderDetails.FrameRailLengthActual, OrderDetails.OrderID, (SELECT count(*) FROM OrderDetails As x WHERE x.orderdetailid <= OrderDetails.orderdetailid AND x.orderid = orderdetails.orderid) AS SeqNo
FROM OrderDetails INNER JOIN ProductTypes ON OrderDetails.ProductType = ProductTypes.ProductType
GROUP BY OrderDetails.OrderDetailID, ProductTypes.ProductTypeSortOrder, OrderDetails.FrameStileLengthActual, OrderDetails.FrameRailLengthActual, OrderDetails.OrderID
HAVING (((OrderDetails.OrderID)=[forms]![orders]![orderid]))
ORDER BY ProductTypes.ProductTypeSortOrder, OrderDetails.FrameStileLengthActual DESC , OrderDetails.FrameRailLengthActual DESC;
Does anyone have any suggestions? I'm not too good with SQL, but I can figure it out (I think!). I've searched all the formus, but all the reference I can find regarding this don't work for me in my application...
I greatly appreciate any help you can give!

Hi,
Just trying to figure out how I can run a select query on some data I have and how to also include an additional field which has a value counting the number of rows.... eg in the first row there would be the usual results and the new field would have a value of 10001, second row would be 10002, third would be 10003.
I've done some searches for sequential numbering but couldnt find anything so far.
Thanks, j

I've taken on the task of transitioning excel reports (and their format) to a database. One report summarizes all the parts of a piece of furniture, and the order of the machines each part goes to.It looks similar to this:
Part# Part Name Machines/Operations
M7264Top Panel 112114116120121325216
M7265Under Top Panel 112114116120121
M7266Base Assembly 411325216311310312316
The table this comes from has both operations and setups, so I used a query to filter only the operations.The query (qryOperations) result looks like this:
PART NUMBEROPERATION ORDER
M7264 112 2
M7264 114 4
M7264 116 6
M7264 120 7
M7264 121 8
M7264 325 9
M7264 216 10
M7265 112 2
M7265 114 4
M7265 116 6
M7265 120 8
M7265 121 9
i need to add sequential numbering (1,2,3,4...) to each line of the qryOperations and use the sequential numbering as the column header.How do I add sequential numbers to the query, that restart after each change in part number? I can do this in a report easy enough, but not a query.This is the SQL of the query I need to have the sequential numbers in...
SELECT tblparts.[PART NUMBER], tblOperationCodes.MachineCode, tblOperationsList.Order
FROM tblparts INNER JOIN (tblOperationsList INNER JOIN tblOperationCodes ON tblOperationsList.OperationCode = tblOperationCodes.OperationCode) ON tblparts.[PART NUMBER] = tblOperationsList.[PART#]
WHERE (((tblOperationCodes.Function)="O"))
ORDER BY tblparts.[PART NUMBER], tblOperationsList.Order;

I have a query that groups the data by customer. How can I create a "Transaction Number" field where I assign a sequential number to each invoice, starting at 1 with the oldest invoice and increasing the sequential number by 1 with each invoice. I need to create this field in a query without code.

How I can create a sequential number in a field that looks like this:
Year-XXX-00
(Example: 15-100-00 -- the next sequential number would be 15-101-00)
I don't want to hard code the year, and the last 2 numbers must be entered manually.
It gets even more exciting --> this number has to be able to be duplicated in a table. Those last 2 numbers is a revision number. We might have a 15-100-00, 15-100-01, 15-100-02, etc.

One of my forms has a text box which is bound to a field called teenumber. This form is set up that "on current" has code
If Me.teenumber = 0 Or IsNull(Me.teenumber) Then
Me.teenumber = Nz(DMax("teenumber", "tblteeofftimesshotgun"), 0) + 1
This enables the text box teenumber to be auto filled with sequential numbers growing by 1 for each record. This database is for a golf tournament and this form enables user to set up tee times for shotgun start for the players.
When the user gets to tee number 18 or whatever the last hole on the course is the teenumber field needs to be reset to 1. With the above code I a unable to do this.

Creating a form against a table with the following fields
EC
Project
Originator
Title
Full description
Effectivity
Etc....
Easy enough to create the Project combo box, problem comes with trying to systematically assign the next EC number.
When I select a Project from a combo box I want an EC assigned with format ECXXXX-### where XXXX is the project number from the combo box and ### is a sequential number. ECs should start at -001 for all projects.
Do I need to add an EC suffix field to hold just the ###? Then what?

I have a rather interesting situation involving creating a primary key. Basically I have two tables.
Table 1
Date, Customer, Part Number, Work Order, Qty tested, qty failed, tech name
Table 2
Defect, reference, quantity(defect), defect cause, part number, work order
The ideal relationship I want to create is that for every Table 1 there are multiple table 2. Regular one to many relationship. The problem is that in the first table it is possible and probable that there will be duplicate records because of the process. The test parts by individual carts, but often they're exactly the same parts with same work orders and same everything else. How should I go about doing this. I don't want to just create an autonumber for each record if possible. Any suggestions?

Is it possible that a composite primary from table A to be a foreign key in table B?
I have two tables: A and B. The A has some personal details such as first name, surname, phone number, etc.
Since no personal ID is given in my project, I am thinking to use first name + surname as the primary key of table A. But when I wanted to make the relationship between A and B (in B I need to use these 2 name fields as the composite primary keys, too) and ticked the option “enforce referential integrity”, an error message prompted out said it could not find the only primary key in table A.
What should I do with this? Or it is impossible to have a composite primary key to be foreign keys (but also primary) in another table?
It will be great if someone could answer this!
Thanks!

I've noticed that the great and the good all seem to recommend not using composite PKs. Does that even go for join tables in the middle of a many-to-many relationship? Not sure I see what's to be gained by adding an ID and making that the PK.
Any comments?

Composite Primary Key in Ms Access 2010. I shall try and explain my tables in detail. So my first table is "Client Database" where the field "Buyer" is primary key. This is connected to my next table "Project Database" which has fields such as Work Order #, PO #, PO Date , Buyer etc where Work Order # is the primary key. Finally "Projects Database" is connected to Order information. Now the problem is until now, I always had 1 PO # for each Work Order #. However now I am facing a situation where my client has clubbed multiple PO #'s for the same Work Order #. I need to trigger the Primary Key Violation only if both the Work Order # and the PO # are the same.

I am trying to set a primary key on two fields. the problem is that the one field is null for some records. They will eventually fill them in. However, because it is null now it will nowt let me set it as a primary key. I tried setting the field, in the properties, with a default value; but it would not take it.

I've received a database that is a digitized population register from the 19th century. All adults have been entered into the database, but all children are missing.
Every person has a unique number that corresponds with the original source (this variable is called 'no', this is not the autonumber primary key thing). Instead of searching in the original source which numbers are still missing, I would like to add the missing numbers (with no additional information, because I still need to type that in).
For example, the table now looks like this:
no - name_last - name_first - occupation etc
1 Smith Henry baker
2 Smith Mary
5 Williams John butcher
6 and so on
So 3 and 4 are missing.
How can I add these missing numbers automatically?

I am trying to run a query that links to tables, orders and invoice together. I am pulling fields from each table, with a relationship between Order# which is found in both tables. The only problem is, order# is a composite key in the order table and strictly a foreign key in the invoice table, referenced through a combo box drop down. When i attempt to create a query, it will not run. (Also will i find a similar problem with my combo box reference?) Any ideas on how to create a query would be appreciated.

I am creating a bridge table to get rid of redundant data. I am doing it by making a composite of the primary keys from the two tables I am bridging.
The error message when I get to a certain point is "You cannot add or change a record because a related record is required in table tblMachCent." Both the numbers I am using to create this composite key are in the tables necessary, so I am not sure why I am getting this problem. Any suggestions??

I have a large table (>1M rows), and I have searched various forums for a way to add sequential numbers by Group. The query I have works, but since it's a large table, I broke it up, and did everything what starts with A-E, the F-Q, etc, and appended to a new table.
This query works, on anything that starts with the letter D or later... A-C will not work.
Basically, the source table is a list of all combinations of Part_ID and UPC_Code. I am trying to number the UPC_Code field, per Part_ID. There is an AutoNumber field (ID) that is in the table as well.
This is the SQL. Query1 is the query that is being executed, so the DCount is within this same query, if that makes sense.
Code:
SELECT tbl_upc.ID, tbl_upc.Part_ID, tbl_upc.upc_code, DCount("[Part_ID]","Query1","[Part_ID] = '" & [Part_ID] & "'")-DCount("[Part_ID]","Query1","[Part_ID] = '" & [Part_ID] & "' AND [ID] > " & [ID]) AS Seq_Num
FROM tbl_upc
GROUP BY tbl_upc.ID, tbl_upc.Part_ID, tbl_upc.upc_code
ORDER BY tbl_upc.ID;
The results of this query are that all Part_IDs that start with A through C produces a Seq_Num of 0, but any that start with a "D" or later number correctly - in other words, the first instance of a particular Part_ID is 1, then 2, and so on up to the total count of that Part_ID.

I just wondering if there is any way to Dmax more than one field? I found something and tried it but it does not seem to work.
Text13 = 10
Text15 = 5
I expected to get a result of just 10 but didn't
Code:
Dim Junk As Variant
Junk = DMax("[Text13] & ', ' & [Text15]", "Test")

after I insert a new record using INSERT INTO and then use DMax() (in a private sub) to look up the new record. About half the time DMax() pulls the new record based on the primary key field (AutoNumber) just fine. However, half the time it pulls the max record prior to the new record being inserted. I.e. record 1001 was added and DMax() pulls record 1000. I'm assuming that my issue has something to do with the timing of when the record is writen/saved in the table. Is there a simple method of refreshing the table that I can use prior to using DMax()?

How do i use DMax() function instead of Autonumber, since the table is empty and it wont know what to do with Dmax() + 1 for next record?
E.g I have a new table Customer_details which contains
customerID
customerName
Age
now if i enter data through forms, i want the CustomerID to be incremental for each new record, so i can use Dmax() function. But since the table is empty how can i tell the form, through VBA that if it is null store 1 else store Dmax("CustomerID", "Customer_Details") + 1
