Using Update Query To Change Record Value
Sep 12, 2007
I have a list of codes that need to be changed if it is part of the a list that need to be updated after being entered into the database. I created a function that holds the old values and what they need to be updated to. To get this accomplished on a form do I just need to write a Update query and then reference the query to the appropriate field I am trying to update with new codes for the 11 codes needing to be changed and leaving the other codes the same.

I have a form with a listbox in it. I want the listbox to update as the record changes.Let me get a little more in-depth...The form will be used to identify merchandise that exists in the company to fulfill current POs.
What I want is for the listbox (which displays Store Locations) to update when the PO# updates on the form (so as the record changes).Currently, the listbox only pulls all the store locations no matter if you hit next record to get a new PO.The two main fields I am working with are PO# (text box) and Store Locations (the listbox).How can I get the listbox to update as the record changes on the form?

G'day, I'm trying to replace a date on a table using an update query. I have the criteria set to [enter date] but it won't put it in the update to block. I know this has to be one of those easy one but after a search and using help I can't nail it down. Much appriciated, Tim
Guess I should add that I'm going to use a command button on a form to run the query and I want it to prompt me for the date.

I'm working on a report that highlights employees when they are leaving on travel and returning on travel and my problem is that the report is only run on the weekdays. It highlights all employees that returned yesterday so for instance on Monday's report it only shows people that returned Sunday and not Friday and Saturday.
My first thought was to make an update query convert those days to Sunday in a new column on my table which would then still cause the employee to be highlighted on monday. I made a table with all Fridays and Saturday's in the year and then in the second column is the Sunday Date to update the new field.
I haven't been able to get the update query to work correctly and was wondering if there would be a much easier solution so a person wouldn't continually extend the weekend table manually.

i'm a Access novice. I have tables with existing data in numerical form, and would like to know how I can use Queries or VBA code to update these values into a new format in a new table. for example the original data might be of race type:
1 - caucasian
2 - african american
3 - hispanic 1
4 - hispanic 2
5 - hispanic 3
6 - other
and i want to regroup these into less types, eg:
1 - caucasian
2 - african american
3 - hispanic
4 - other
how can i achieve this in Access? i know how i can do this conceptually with "if" and "case" statements, but I have no idea how i can do this in Access. I don't want to mess with the original data, so please help with CODE or QUERY examples.
thanks!!

Given a table field that is a hyperlink type.
I need an Update Query to set all records of that table so that the Displayed Value part of the hyperlink field (not the Address part) is set to a particular value.
Any ideas how?
Thanks.

i want to be able to create an On Click Event when pushing a command button that will run an Update query to update a record and after it has been updated that specific record will pop up on a Form and be displayed. i know a different way is to run the Update query and then have it displayed in a Select query but i want it to be displayed on a Form instead. is it possible?

I have a table called tblCompanies. When a company acquires another company, I need a method by which the acquired company's CompanyID (PK) can be updated to the new company's CompanyID (PK). I also need to be able to update all related CompanyIDs (FKs) to the new value in related tables.
In cases in which the new company does not have an existing record, there is no problem: the company name simply gets changed to the new company and the existing CompanyID is maintained. I then use an audit table and Track Changes function to keep track of the company name data and a union query to keep the old names in the selection lists.
The problem is when both companies already have existing records in the table.
So, let's say I have records for Company A and Company B. Company A merges with Company B and Company B is now the main record. What is the best, simplest and easiest way to update the CompanyID (PK) from A to B and change the CompanyID (FK) to the new value in all related tables?
I am envisioning a pop-up form that directs the user to select the new company and then an update query happens behind the scenes... but exactly how does the criteria for the update query get selected and how do all the related tables get updated? My vba skills are pretty basic, will I need extensive coding to do something like this?

Hi,
Don't know if this is possible, or if im being just plain stoopid:
Is there a vb command that will update a record without having to use a query?
My problem is this - I have an HR database which has allows us to add employees that are going to start. We then set their [Activity Status] from "Starting" to "Active". At the moment this is done manually, but what i would like to do is have this automatically change when the [Start Date] = Date().
The code i tried to use (but is obviously wrong) is:
If [Activity Status] = "starting" And [Start Date] < Date Then
Set [Activity Status] = "Active"
End Sub
Any thoughts what i might change "Set" to, to make this work?
Thanks,
Ferg.

Hi,
I have Access 2002 on Windows XP.
The last version of Access I've used was 97 but I'm getting back into it. I've read a couple of things that recommend creating a form based on a query, not a table, especially if a calculated field is involved.
When I create a select query based on 1 table, I can change/add/delete records right in the results of the select query, which will carry over to the form just fine.
However, when I use an additional table and join them in my select query, I can no longer update any of the fields that show in the query result. The link I'm using is just a 1 to 1.
How can I get around this? I'm using the second table just for lookup purposes (use the value of one of the fields in a calculation), but I want to be able to update the fields from table 1 from the form.
Thanks.

Hi all,
I've got this form working ok but need to add some extra functionality but haven't a clue how to do it!
http://www.access-programmers.co.uk/forums/attachment.php?attachmentid=10175
The uploaded database has two main forms. The first is used to enter customer data, the second runs from a query and shows all those records that have been completed in the first form (frmCustInfo - AgentLog = Yes) but not completed in the second form (frmControlsSource - AnalystLog = No)
Then more data is input into one of the subforms (frmControlChecks). Now in order for me to see the results of the queries connected to two other subforms I have to move off the record and back to it (for the record to be saved and then the queries run)
After moving back to the record, the query results on the right (Information Only) are manually added to the last subform 'Input Two', then the user would move on to the next record and do the same.
-------------------------------------------------------------------------------------------------------------
What I need it to do then is this: When the user tabs off the last field in the subform (frmControlChecks), the queries to the right (two subforms) would run, showing the results and also populating the last subform (frmAnalystInput)
The user would then click AnalystLog and move to the next record.
I hope this is possible without redoing the forms/queries because it's taken ages to get this far
I've also added info in this sample database and some working data if you want to take a look...thanks for any help

I can do this in like 5 seconds in SQL Server but I can't get the query to even ALLOW me to update records.
Table1 - Columns
Query1 - ColumnDesc
Code:
SELECT DISTINCT C.Column
FROM Columns C INNER JOIN (
SELECT Cols.Column, Count(Cols.DataType)
FROM (SELECT DISTINCT Columns.Column, Columns.DataType FROM Columns) Cols
WHERE Cols.DataType = 'char' OR Cols.DataType = 'varchar'
GROUP BY Cols.Column
HAVING Count(Cols.DataType) > 1
) C2 ON C.Column = C2.Column;
Simple, straight forward query, that grabs all the rows from table Columns where there are more than one DataType per Column [name], and either one of those datatype strings are 'char' or 'varchar'.Now I want to UPDATE table Columns to set all of the columns whose "column" value is in the above query, and set all those DataType values to 'VarChar'. Thus I run that UPDATE query, and the above query should come back empty afterwords in SQL Server I would simply write:
Code:
UPDATE Columns
SET DataType = 'varchar'
WHERE EXISTS (
SELECT 1 FROM ColumnDesc INNER JOIN Columns ON ColumnDesc.COlumn = Columns.Column
)
And this would already have been done.But Access doesn't like that syntax. using the designer it created sql like this:
Code:
UPDATE Columns INNER JOIN ColumnDesc ON Columns.Column = ColumnDesc.Column
SET Columns.DataType = 'varchar'
But that wasn't an "Updateable" query.I have to run this on several patterns and right now I'm completely screwed if I can't get this to work.
My end goal is to have:
SELECT DISTINCT Columns.Column FROM Columns
return the same # of rows as
SELECT DISTINCT Columns.Column, Columns.DataType FROM Columns
for each duplication I will have to do different algorithm, but I can't even get one update query to work so I'm currently frustrated (and ready to reaffirm my belief that Access should have been discontinued 5 versions ago).

Upon closing my frmInventory the amount stock of stock is checked against a minimal stock value. If the stock amount is below a set minimal value a subsequent form is opened telling you that stock is low and an email message is generated to notify a manager. I have a checkbox on that form which is set to "True" upon close using an update query. The checkbox is there to give users the option to either send or not send a reminder message that stock is low when a message has already been sent earlier.
The problem is that using that update query ALL records are set to "sent=true" and not just the 1 record I intend.
This is my code in the "on close" event:
DoCmd.OpenQuery "qryUpdateEmailMinimal_True
and here's the SQL:
UPDATE tblInventory SET tblInventory.emailSentMinimal = True;
I assume what is missing is a reference to an inventoryID number. How do I do that?

i have this problem that is bugging the crud out of me:
sql="UPDATE bedrifter SET pr=" & Request.Form("pr") & ",totalindexedpages=" & Request.Form("tip") & ",totalinboundlinks=" & Request.Form("til") & ",description='" & Request.Form("dsc") & "' WHERE created='" & Request.Form("ts") & "'"
conn.Open connStr
conn.Execute(sql)
conn.close()
Set conn = nothing
when i run this code it updates the correct record (line in my access db) but then it also adds a new line with only that info in the update query. why is it doing this? when i update using the ID instead of using the timestamp in the WHERE clause it works fine. really frustrated...

I have this update query that is triggered by an after update event on a main form. The record being updated are in a continuous subform. It works well except from the last added/modified record. If I save and close the form and then open it again it works for all records but if modify or add a record, the update query will not work for that last modified/added record.
I have tried several things such as save record, use dirty = false for the on exit event of the subform control but nothing works. Here is the procedure:
Code:
Private Sub cboPoCurrency_AfterUpdate()
On Error GoTo ErrHandler
Dim db As Database
Dim strSql As String
Dim lngID As Long
Dim dblRate As Double
Set db = CurrentDb
[Code] ....

I have two tables. PreOrder and Order Tables. When our customer actually order a product, I want all information of that product to move from PreOrder table and append it to Order table. Currently, my user has to run an append query to add the record from PreOrder and add it to Order table. After that, she has to run a delete query to delete the record from PreOrder table. Since our query is setup to run by date, and order number..My user has to type the same thing twice. Is there anyone out there know the easy way? Thanks in advance..

On a push of a button from a form, I want to locate specific records within the table and update a field to Null if it matches a name
Dim strSQL As String
strSQL = "UPDATE tblmaster SET Score = "" WHERE [AdvocateName] = 'Anna Maria'"
DoCmd.RunSQL (strSQL)
I'm certain I don't have the syntax correct between the Set to Null and WHERE clauses..

Hi! Please help!!!
I'm currently building a bookings database and have encountered an alert message that I cant seem to rectify -
"You cannot add or change a record because a related record is required in the table 'Booking Details'"
Basically - I have a 'Customer Database' form that is linked (via command button) to a 'Booking Details' form. Within 'Booking Details' I have 2 sub forms - 'Booking Quote' and 'Booking Payments'. Both subforms are linked to the 'Booking Details' form by the 'booking ref' field with RI.
I have no problem updating information in the 'Booking Quote' subform, but when I try to add information to 'Booking Payments' it states the above message.
Can anyone please advise as to how I can prevent this happening? I'm slowly losing my mind....!!!
Many thanks,
Stacey

Currently I keep getting this error: "You cannot add or change a record because a related record is required in table"..My current tables are this:
Primary Table with persons info:
Primary Key - Auto number generated
Name
Address
Email
Phone
I have 4 other tables with use check boxes.
ex:
Table 1 - Geographic locations visited
ID - Auto generated
USA
CANADA
ASIA
ECT...
Table 2 - Languages Spoken
ID - Auto generated
Spanish
Chinese
English
Table 3 - Skills
ID - Auto generated
Hunting
Dance
Singing
Weaving
Is this not a genuine one-to-one relationship table? I mean No two people would have had visited the same places and speak the same language no? I tried to create a one to one relationship with the primary key to the auto generated ID of the child tables but I'm sure that is not how you do it. Also when I try to save the check boxes in my form and I close it and come back it doesnt save and is blank again. Is it because my form gets its information from a query that takes all the information from all the tables.
how I can get this to work properly? Am i to make use of a foreign key? I've read a lot about it online and watched youtube videos but I dont see why I need it here in this case. Is there a way to set the IDs in the child tables to be the ones from the primary table? Or do I have to use a foreign key and manually input the primary ID into them?
Or would it be better to have all these child tables in the primary table and have one large table instead? I just didnt do that because one of them has like 20 checkboxes with cities and locations

I have created three tables, all of them are connected by one-to-one relationship by same field, as you can see in the screenshot. and at the same time I have created three forms for each table. then I brought two forms in one remaining form. so whenever I entered data in first form and click on the next tab in which another form exist, it gives me this error: "you cannot add or change a record because a related record is in table".

Before you start yelling, use the search. I did.;)
But the solution mentioned on this forum (place me.lastupdated = Date() after BeforeUpdate event) doesnt work for me. My situation: I have two forms. On the first you are asked for an registrationnumber. This is used to open the second form with that registration number so you can fill in data. I want the date on which things are changed on the second form to be saved. If I use the BeforeUpdate event, I get an error when I try to open the second form. When I use the AfterUpdate event, the date is changed but not stored. Any solutions? :confused:

Hello,
Firstly, I am very much self-taught on access, so there are several gaping holes in my knowledge, and my database structure is probably not wonderful! I have been learning as I go along, so in the initial stages I have built in several problems which I am now discovering!
My db is designed to track suggestions - i have a table where the idea, progress etc is stored [tblIdeasBank]. This contains an 'originator' (person's name) which is linked to a second table, where the names are stored [tblPeople].
Originally I set up tblPeople with the Primary Key as FullName (e.g. Joe Bloggs) (guaranteed to be unique with the small number of people that would be involved), and a second field called InitialLastName (e.g. J Bloggs). It is this second field that is stored in the tblIdeasBank. Data verification came from the user having to select a name from a drop down box, so there is no actual 'relationship' between the tables. (Didn't realise how useful they were at the time!)
The db has been so successful :confused: that it is now going to be rolled out across the company, which gives me two problems. To populate all the names, I need to import them from Excel, where I will have FirstName and LastName. I have now realised that it would be more sensible to just store these, and create InitialLastName where needed. Also, I may well have duplicate names, so I need to create a unique ID, and a proper relationship. (Yes, I know I should have done that in the first place).
So, I have:
tblPeople:
.FullName (Primary Key)
.InitialLastName
tblIdeasBank:
.Originator (stored as InitialLastName)
And I would like:
tblPeople:
.PersonID (Primary Key)
.FirstName
.LastName
tblIdeasBank:
.IdeaID (Primary Key)
.Originator (stored as PersonID)
With a One-Many relationship from PersonID to Originator
Any ideas how I would go about doing this and changing the Originator for each idea from InitialLastName to the relevant PersonID number, without corrupting the data?
I have searched through Google and various groups, but cannot find a useful answer, so any pointers gratefully appreciated!
Thanks,
Nick
