General :: DLookup - Resetting Sequence Number In A Table?
Oct 8, 2013
Occasionally a user of mine needs to reset a sequence number in a table.
A few months ago I made him a simple app that has two text entry boxes and a button. The first text entry box uses a dlookup:
Code:
=DLookUp("sSessionNumID","qryGetAPIsessionLastValue")
...the other textbox ties to an update query, which updates the sequence number with the new value supplied by the user. Simple.
Then about a week ago it stopped running the dlookup part - nothing shows in the text box that is to show the current sequence num.
Oddly, if I enter a value in the update text box and press the button to update the sequence number (which still works) -- the previously dormant dlookup textbox now shows the new value - so it works ...it just doesn't want to work on this one workstation unless the update query is run first.
What can this be? The update button merely calls a DoCmd.RunSQL with both an insert (storing old value locally in ms access table) and an update (updating the sql server table's seq number using an ODBC DSN and sql server driver).
It's almost like the dlookup falls asleep now and won't wake up until the update is run...

In month-end posting - I basically delete all the records from my transaction file. And in doing so - it seems to be resetting the auto number index - which is causing me major problems.
The resetting of the index after deleting all the records is normal.
I am working in VB 2010 - using a 2003 MS Access database.

i want to know such a method that if i give a number, the database find me the next available number from the given list in the table.for example, i have a table having list of numbers like 6500, 6501, 6502 etc, I give the number 6500, the database should give me the next available number in sequence from that given list in the table.

I am looking to make a table which adds a sequence number to my records.
Example data would look like this
Acc no Date
1234535 01/01/2013
1234535 05/01/2013
1234535 11/01/2013
9876543 02/01/2013
9876543 22/02/2013

I want it to add a deq based on the account no then date in sequence oldest to newest.
Acc no Date Seq
1234535 01/01/2013 1
1234535 05/01/2013 2
1234535 11/01/2013 3
9876543 02/01/2013 1

I'm creating a table with times of the day from 08:00 to 17:00 in 15 minute increments.
I'm going to use the table as a lookup to make it easier to enter an appointment time.
I don't really want to type them all by hand - does access have an equivalent to excel's drag and autofill a sequence? is it just as easy todo it in excel then cut and paste it?

Ok, so I have this table (tblPayPeriod) with the fields Start Date, Stop Date, Pay Period & Percent FY. The Percent FY field is a Number field that gives off the percent of the fiscal year (FY) that we are in.
Then I have a report (rptDistrictMgr) that in the header I want it to display what percent of the fiscal year we are in based on the Auto_Date that is in the header.
So, if the Auto_Date is December 17, 2014, we are (according to tblPayPeriod) 24.1% into the fiscal year and I want the 24.1% to display in the text box which called Text99.
I would just like a simple dlookup that I can use as the control source of the text box or an expression to put into the On Load sequence.

I have a number of tables (I know someone is going to say you don't need a primary field for these tables but I want to use one) that are basically lookup tables for combo boxes. Generally I use an autonumber to identify the ID of each record. There are occasions when all the records need to be changed (i.e. delete all old records) - does anyone know how I can programmatically (or otherwise) reset the autonumber from the last used back to "1" if all records from the table are deleted.

I have a primary key field called "Issue Number", with the properties set to auto-number.
After testing, I need to set it back to zero before going live.
I deleted all the records and did a compact and repair, but the first number that comes up is the one after the last one used during testing.
Help????
Thanks

The title probably doesn't give an idea of what I need, so here goes.
We currently have reference #'s for our bills that include the date requested in mmddyy format, the first 3 letters of the customer, the initials of the order taker and finally a sequential number to show the sumber of bills that day.
example: 120705SEAGMM02 2nd order taken by GMM for Seagate on 12/7
120705SEARLH01 1st order taken by RLH for Seagate on 12/7
I want to generate this number automatically based on the date entered and the initials given of the user. We only deal with one customer at our desk so that will always be "SEA".
I have a query that generates the first portion (date, customer, and initials):
SELECT Format([REQDATE],"mm") AS [Month], Format([REQDATE],"dd") AS [Day], Format([REQDATE],"yy") AS [Year], Format([REQDATE],"mmddyy") AS [Both], [Both] & "SEA" & [PickUpReqData]![INITIALS] AS REFNO
FROM PickUpReqData;
But I can't seem to get my head around the part of generating the number. I know I had done this in a database I created 2 jobs ago but all my files were flooded out in Katrina. (I have since relocated to Atlanta, although I'm not looking for sympathy. But I will take what I can get!)
Anything to point me in the right direction will be appreciated. I am looking to have this on a form and feed the REFNO field in the PickUpReqData table.
Thanks.

DLookup function. (this is for a stamp collection database).
On my form ("InventoryInput") I have a text box called "Catalog" for a numeric entry and a text combo box for selecting a "Country" in drop down list.
I want to query a table called "CatNameList" to get the "StampName" of the item (based on the entries of Catalog and Country) and populate that name in the text box. The fields in this table are called "StampName", "CatNumb" & "CName" respectively.
I have successfully placed the following expression in the control source of that textbox and able to populate the StampName I need based solely on the catalog number alone.
That express is :
=DLookUp("StampName", "CatNameList", "CatNumb = Form![Catalog]")
So it will populate the "StampName" data to match the "Catalog" number entry just fine.
However, I need to add a second layer to incorporate the Country.
Example : There is a catalog "1" for "USA", and a catalog "1" for "Canada" but both have different "StampName".
I have been attempting to get that second piece added with no success. Here is the expression I have been trying to get to work :
=DLookUp("StampName", "CatNameList", "[CatNumb] = " & [Catalog] & " And CName = '" & [Country] & "'")
Right now, the text box is just blank with the above expression. I thought it may be because there was no match found, but I have triple checked to ensure I have the spelling correct on the country name in both places.
Basically, I just need the dlookup to take the "catalog" and "country" off the form and match it to the "CatNameList" table fields of "CatNumb" and "CName" to give me "StampName" field back on the form.

Having problems getting dlookup to work in the control source field of a text box.
My form has fields : Catalog # (numeric value) and Country (drop down text selection).
I would like to query a table CatNameList for a name (text) if the catalog # and country find a match on the table.
My field names on the CatNameList table are : Name, Number (to validate against the Catalog # entered on the form) and CName (to validate against the Country drop down on the form).
I am successfully able to populate the name from the CatNameList table on my form using lookup of the catalog # using this :
=DLookUp("Name","CatNameList","Number = Form![Catalog #]")
However, I will eventually have several catalog numbers that will be identical in the table CatNameList, thus why the country is important as the second criteria to be added into the dlookup.
I have tried for a few hours unsuccessfully to add the second portion to my dlookup.
This is what I have currently (not working) that I have been playing with, I'm sure I'm missing a quote mark, & or something simple.
=DLookUp("Name", "CatNameList", "Number = Form![Catalog #] And CName = ‘”& Form![Country] & ”’”)

Hi!
1. If accidently a record or two in a sequence are deleted, how will you know that this has happened! What type of validation can be enforcedto prevent this?
2. How do you make your Tables, Quries, Forms, Reports, Macro tamper proof?
Please help!

I have a query that captures date values from a table based on a between function that works fine. What I would like to do is associate a sequence number fro each date value returned and either perform a make table or leave it as a select query. If I create a table I know that I aam able to add an autonumber field but the query is executed frequently and performing the addition of the autonumber field is not feesible. Any thoughts how I can generate the sequence number each time the query is executed?
Thanks

I would like to insert a sequence number into a query that currently returns 7367 rows.
Here's what it looks like now:
ID_NUM
DTE_FIN_TRANS_RCV
1322
9/27/2012
1322
7/10/2012
1011
7/2/1999
1011
9/22/1999
1011
10/21/1999
Here's the desired outcome with sequences:
ID_NUM
DTE_FIN_TRANS_RCV
SEQUENCE
1322
9/27/2012
1
1322
7/10/2012
2
1011
7/2/1999
1
1011
9/22/1999
2
1011
10/21/1999
3
All I need is a way to number rows with a value higher than the previous for that particular ID_NUM.

I'm trying to code for a 'duplicate record' button on a form that, as well as copying the values of all the controls of the previous record to the new record, makes a certain control (which contains a number) increment as appropriate.
There are two controls on the form which contain the start and end values of a numerical sequence (of potentially any length) e.g. the range 48-82 shows 48 in text box boxREGSEQSTART and 82 in the text box boxREGSEQEND OR the single value 99 shows 99 in text box boxREGSEQSTART and text box boxREGSEQEND is empty. In a record, the value of boxREGSEQEND would always be higher than that of boxREGSEQSTART or would be blank.
The appropriate incrementing action would be:
After clicking 'Duplicate Record' button, If there is no value in boxREGSEQEND in the record being copied, then in the new duplicated record the value of boxREGSEQSTART should be 1 greater than the value of boxREGSEQSTART in the record it has been copied from.
i.e. the record being copied is records a single item, a single value, and the next record should show the sequence moved on by one
OR
If there is a value in boxREGSEQEND in the record being copied, then in the new duplicated record the value of boxREGSTART should be 1 greater than the value of boxREGSEQEND in the record it has been copied from.
i.e. the record being copied is recording multiple items, a sequence, but the next record should still show the sequence moved on by one
I can get the duplication to work no problem, and I can get the incrementing to work fine for the first set of conditions, but can't for the life of me get it to increment when there is a range!
The logic (in my head, expressed as best I can in the macro language ) for the whole sequence of actions goes like so:
RunMenuCommandCommand SelectRecordRunMenuCommandCommand CopyRunMenuCommandRecordsGoToNewRunMenuCommandCommand SelectRecordRunMenuCommandCommand Paste
If [boxREGSEQEND]=[IsNull] Then
GoToControlControl Name boxREGSEQSTARTSetValueItem = [boxREGSEQSTART]
Expression = [boxREGSEQSTART]+1Else
GoToControlControl Name boxREGSEQSTARTSetValueItem = [boxREGSEQSTART]
Expression = [boxREGSEQEND]+1GoToControlControl Name boxREGSEQENDSetValueItem = [boxREGSEQEND]
Expression = [boxREGSEQEND]=Null
Which I would assume would tell the program to copy the current record, make a new one and paste the copy, then if there was a range recorded in the original, start the numbering of the new record one number higher than the end of that range and clear the way in the new form in case it also records a range, otherwise just increment the sequence along by one.

Hi -
Suppose I have a generic query that returns a group of records.
Is there some way to generate a field containing the number sequence of each record? E.g. if there are 10 records, generate the numbers 1 through 10?
Must be a simple way to do this, I'm just a bit dense today...
Thanks,
-g

I have two tables - one with parent Records, the other with child records. The ID links the two tables .I want to add a sequence number on the child table which resets at each ID change. What would be the best way to accomplish this?
Code:
PC_ID ID Name Address
P 1 Parent1 Address1
P 2 Parent2 Address1
PC_ID ID Name Address SEQ
C 1 Child1 Address1 1
C 1 Child2 Address1 2
C 1 Child3 Address1 3
C 1 Child3 Address1 4
C 2 Child1 Address1 1
C 2 Child2 Address1 2
C 2 Child3 Address1 3

I have a table in a database with 7 columns. The data is sorted by Date1 in descending order.
For each pid I want to put the sequence numbers
First record has two conditions
If string 2 is null then start numbering from sequence1
If string 2 is not null then start numbering from sequence2
If string 2 = string1 then
Sequence1 = 0
Second record has two conditions
Number sequence2 with the value 2 or 3 depending on the line one
If string 2 = string1 then
Sequence1 = 0
Else
Sequence1 = next number
Same condition for the rest of records

How to extract or calculate the number of records in a sequence - e.g. in a table/query ordered by ID and date, the number of consecutive records by date for a given ID that have a value >= 50 in a given field. Is there a way of doing this purely within a query, or would I have to resort to a VBA loop through a recordset and keep a count of the consecutive records that match that criteria?

I have a Primary Key field named Member ID(Number format) in a Table named Mail List. The field is populated with existing ID numbers and my need is to use my Member Entry Form to increment by 1 from the last entry.
I have gleaned from other references that this can easily be achieved by the following entry in the Default Value of the property sheet for the relevant field;
=DMax("Member ID","Mail List")+1
The Form saves without error but when I attempt to add a new record in the entry form, the ID Number reads "#Error".

At present I am running Revit Architecture with DBLink to access to edit fields for shelving etc.
What i am doing is fitting out warehouses with 600+ shelving units and they are all numbered.
These numbers are tagged in the drawing.
What I am hoping to do is export the data to access (completed) then amend any changes within access.
Normally, we would put say 600 shelving units on a drawing all tagged 1-600. But then the client may want to delete shelving unit 321.
Leaving the drawing with all shelving units tagged 1-320,322-600.
How would i go about it so access renumbers all data after the deleted field (ie number 321)?

I do not want to use AutoNumber to generate my Stock Control Number. I need to somehow automatically generate a number so that when I enter data and then make an error it does not mess up the numbering system like AutoNumber does.
I am a novice who is will to try to do what it takes to get this going properly. I cant find anything online relating to Access 2010.

I am trying to get the max of an integer field if the ProjectNumber field is equal to the ProjectNumber field in the current record. I have used code similar to the one below before but it was on a date field, then add one.
Me.RevisionNumber = Nz(DMax("[RevisionNumber]", "dbo_ProposalLog", "[ProjectNumber] =" & Me.ProjectNumber), 0) + 1
The ProjectNumber field is a text field.

I have a set of transactions with a Unique ID field and a date. I want to add a field based that gives me the sequence of events for each Unique ID in order of when it happened.
For example, if customer X has 6 transactions, the sequence field would have a number (1-6) in each record that corresponds to the order in which those transactions occurred. The first transaction would have the number 1, the second would have the number 2 and so on.
