Queries :: Find Value In Recordset Then Update?
Apr 4, 2014
I am not sure if my coding is efficient or not but it takes so long to read lets say tbCOMPANY 40k records and find if values of two columns exists in tbRESULT which holds 30k records. Then if it doesn't find any records in the tbRESULT it will just insert the row otherwise an update will be executed.
What I did was:
1. Read tbCOMPANY each row using for loop
2. tbCOMPANY.FindFirst to lookup if values exists in the tbRESULT
3. If tbCOMPANY.noMatch, it will insert into tbRESULT
4. else it will update the matched row in the tbRESULT
Its been taking like over 30 minutes to process this and still ongoing and it will still keep on running. Now Access is showing as Not Responding in the task manager.., Any efficient way to do this?

I have a table Billing_Temp that I need one field updated if I find a match in another table Random_Temp. I runt the query and it prompts for "Enter parameter value: Random_Temp.peopleID... what could be going on? Both tables have a field called peopleID and always Billing_temp has many more records than Random_temp:
UPDATE Billing_Temp SET Billing_Temp.audited = -1
WHERE (([Billing_Temp].[peopleID]=[Random_Temp].[peopleID]));

The company I work for is consolidating regional server space onto a single server. I have relinked all of my tables, but my ~180 queries are still pointing to the old server.
My question: Is there a script or other process that can be executed that will search through all my queries within the database to find the string "dbo_tbl" and replace with "dbo_vwtbl"? I would very much like to avoid taking each individual query to a notepad...

I have an "order details" table that needs to populate a field called "Voucher" with data from another table called "codes". The "codes" table also has a true/false field called "allocated" because once allocated the code cannot be re-used.
I am trying to work out how to automatically allocate the next unallocated code in the "codes" table to each record in the "order details" table when that order details record has a DiscountID of "92".
Order Details Table Fields and conditions/criteria:
ID - primary key
DiscountID - only when the DiscountID = 92
Voucher - only populated when Discount ID = 92
Codes table Fields and conditions/criteria:
ID - primary key
code = text field with a code like "einstein01", "einstein02"
Allocated = False
Is there a way to put the next available code into the order details record then mark that code as allocated in the codes table. Then, move on to the next order details record that has a discountID = 92, input the next unallocated code and mark that code etc. etc.
Ideally, I would like to do this to happen via an event when the Order forms button "Close" is clicked.

I want to update a field (field1) in each record of a recordset (qryUpdate)
I got the following code (in green) working fine - so far so good. I actually need to update the field from a selection from an unbound combo box. This looks up a table with two fields Period ID (autonumber PK) and a text field called Quarter. I've tried various combinations including the code in red and code such as
"rst![field1] = Me.cboPeriod"
"rst![field1] = Me.cboPeriod.Column(0).value" etc
but can't get it to work. It has to be something simple but I can't see it.
Private Sub cboPeriod_AfterUpdate()
Dim rst As DAO.Recordset
Set rst = CurrentDb.OpenRecordset("qryUpdate")
Do Until rst.EOF
If IsNull(rst![field1]) Then
rst.Edit
rst![field1] = 5
rst.Update
End If
rst.MoveNext
Loop
End Sub
Private Sub cboPeriod_AfterUpdate()
Dim rst As DAO.Recordset
Set rst = CurrentDb.OpenRecordset("qryUpdate")
Do Until rst.EOF
If IsNull(rst![field1]) Then
rst.Edit
[rst![field1] = Me.cboPeriod.Column(0)
rst.Update
End If
rst.MoveNext
Loop
End Sub

I am trying to have the code perform these things but unable to do so. While the code would still work, it will not move to the next user with either no date or the earliest date.
Goal:
-Go through the query record by record according to the date/time field
-Find the record with no date or earliest date (in that order)
-change its date to today's date
Code:
Code:
Private Sub Command56_Click() Dim i As Long
With Screen.ActiveForm.[AMID]
Dim LResponse As Integer
LResponse = MsgBox("Do you wish to auto-assign to an Accreditation Manager?", vbYesNo, "Continue")
[code]....

I have some vba where I'm importing a text file and splitting it out into a table. For the most part its working just fine.
But I have a line of data that I need to pull out the string right after "Old" - Murphy and right after "New" ZMurphy
Acc# : 111111 This is test data, Person : 22222 Old Murphy New ZMurphy
I'm thinking Instr() could do this but I'm unable to get it to work.
I am using Access 2010...

I have inherited an old database with a new field to add some new invoice numbers and increment the number to each recordset by + 1. Starting at 001. I have formatted the field to a Number Field and formatted it to 000"/2015". I now need to populate over 2000 records with the sequential numbers for each record.
I have created the following code as my attempt. Of course it doesn't work!
Code:
Sub AddNumbertoRecords()
Dim db As DAO.Database
Dim rst As DAO.Recordset
Dim counter As Long
counter = 1
Set db = CurrentDb()
[Code] ....

How it works: You search for a User, and then you search for a Serial.Now, what if I want to edit the table? (inside the subform, the results). I added an openRecordSet, and Parameters, but I still get the error saying that Recordset cannot be updated.Why? I opened and sent parameters but still fails.

morning
i am adding a new row to an adodb.recordset, one of the fields being a Memo datatype.
all the other fields will write to the database fine, but with the memo, it will mysteriously disappear when i call rs.update
response.write(rs("my_memo_field")) 'give correct output
rs.update
response.write(rs("my_memo_field")) 'gives nothing!
any one else had this happen and have a solution?
cheers

I found this code and have substituted parameters to suit my own needs however the loop is not working. Only the first record in my recordset (which is a test recordset of only 3 records) is being updated.
Also, for testing only, the edit or update being applied is trivial: Description = "WHITE RESIN". If i can get the loop to work I want to substitute higher functionality to the module.
Private Sub Update_Click()
Dim dbs As DAO.Database
Dim rsQuery As DAO.Recordset
Set dbs = CurrentDb
Set rsQuery = dbs.OpenRecordset("qryRmResin", dbOpenDynaset)

I have a form in my front end database that is supposed to allow a user to search for a record based on account number and then make changes to the that record and for it to save in the back end database. I have the search function working where it populates different input boxes on the form with what is stored in the back end database but I cannot get the update function to work. I have tried to assign each input box with a variable and then run an Update SQL function to update each of the fields but the updates are not storing. Any example of a successful update statement that uses VBA variables in it or a way to update a specific record via a recordset type function?

I have written code to retrieve data from a back-end, that is then bound to a form (late binding forms).
From the retrieved record set I want to update a combo box using 1 field from the data in the record set, only showing unique records in the list.

I am trying to update a recordset using VBA based on the max "process instance" from another table. After the code executes, the field I am updating is still blank.
Code:
Set rs = db.OpenRecordset("myTable", dbOpenDynaset)
If Not (rs.BOF And rs.EOF) Then
rs.MoveFirst
Do Until rs.EOF = True
emplid = rs![Employee Number]

I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:
Start Date/Time
End Date/Time
Employee
At the moment this is what the format of my report looks like (I removed other unnecessary fields):
StartTime----------EndTime---------------Employee
12/06/2014 01:00--12/06/2014 03:00------John Smith
12/06/2014 04:00--12/06/2014 06:00------Jane Doe
13/06/2014 02:00--13/06/2014 05:00------John Smith
13/06/2014 08:00--13/06/2014 08:00------Jane Doe
I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?

Code:
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("Complaint", dbOpenDynaset)
[Code] ....
I find the record, and then try to update a field. The drop down menu field gets updated after it is initially changed from blank to a value, but it never changes after that though the re!C02 field has the correct newer data when I change it again.

My update statement is shown below. What this is to do is change the PGTIN record in PP TBL to the GTIN that is in the UPC TBL where the UPC Code on the form is the same as the UPC Code in the UPC TBL. I am getting the error message "can't find field..." I have double and triple checked the field names but cannot find my error. Both PGTIN and UPC Code are text fields.
strSQL = "UPDATE [PP TBL] SET [PGTIN] = '" & [UPC TBL].[GTIN] & "' WHERE ([UPC TBL].[UPC Code] = '" & Me.UPC & "');"

I Have a forms which brings up a record in textboxes when you hit a search Button using a value that you type into a Textbox called BarTxt. My problem is that this value may not be unique. Therefore I'm trying to find and update the table using 2 values from the table (Barcode and PurchaseOrder).I have entered the code
Code:
Private Sub SearchBtn_Click()
PNTxt = DLookup("PartNumber", "BookInTable", "BarCode ='" & [BarTxt] & "'" And "PurchaseOrder ='" & [POTxt] & "'")
End Sub
This however is just bringing up a Type mismatch error. Even though both are text fields.Also even if I just use Barcode to search which works. My update Code
Code:
DoCmd.RunSQL "Update BookInTable SET DateBookedOut = '" & Me!DateTxt & "' WHERE BarCode ='" & [BarTxt] & "'" AND PurchaseOrder ='" & [POTxt] &
I get an Compile error saying "expected expression".

I have a problem in multi user enviroment, with finding and locking a record in database.When one user finds, blocks and edit record ... another user in the same time can find the same record and overwrite it (User and Status values). It is just like he didn't see the changes making by another user.Each user have a copy of the front-end, back-end is on the shared disk.Here is the code to find new record:
Code:
...
Set rs = db.OpenRecordset("tblTable1", dbOpenDynaset)
rs.FindFirst "[Status]='New' And [User] Is Null"
ws.BeginTrans
rs.LockEdits = True
rs.Edit
rs![User] = username
rs![Status] = "Assigned"
rs.Update
ws.CommitTrans
rs.Close

I'm a having a problem with a Yes/No datatype. Fundamentally, my code looks like this:
strSQL = "SELECT * FROM tblAddresses " & _
" WHERE YPID = " & Me.Parent.IDNUMBER & " AND CurrentAddress = yes"
Set rs = db.OpenRecordset(strSQL)
Now this statement returns 3 records even though only 1 Current Address exists.
false also returns 3 records
true also returns 3 records
no also returns 3 records
-1 also returns 3 records
0 also returns 3 records
1 RETURNS 0 records!!
If I look at the table in Access, I only have 1 CurrentAddress record for my IDNumber.

I'm fairly new to SQL and I'm trying to input data into this form I've created but it tells me that "this Recordset is not updateable". Here's my SQL code, I'm not certain this is the problem though.
Code:
SELECT [Annual Instructor Report County Summary].*, [Camps, SS Events, Events, Total Members].*,
[Archery Members].[numArchClubs]+[Archery Members].[numArchNon4H]+[Archery Members].[numArchCamp]+
[Archery Members].[numArchSSEvent]+[Archery Members].[numArchEvent] AS totArchMem, [Rifle Members].
