Modules & VBA :: Formula Based On Record Number - Recordset Required?
Dec 14, 2014
In order to arrive at the required solution I have to perform a calculation, using data from each successive table record (in chronological order). The result of each calculation must then be used to arrive at the result for the next calculation.
In other words I have to update a variable based on data from each record, sorted in chronological order, and use the final result to populate a field on a form.
Is it time to break out my copy of "VBA For Dummies" and start learning how to use Recordsets?

I have a table in Access that I have a form saving new records to. Before this save occurs, I would like Access to check if the account number already exists and if the account does exist if it is outstanding. If both of those conditions are met I would like a message box to display and cancel the save as it is a duplicate. I can't seem to get it to work though.
I was thinking to use a filtered recordset based on one of the conditions and then perform a find on that recordset to see if it is null.
Code:
dim acct as long
dim rstfiltered as DAO.Recordset
Set rstfiltered = CurrentDb.OpenRecordset("SELECT * FROM tblclstrack WHERE [Request Status] <> 'Completed'")
acct = Me.cd_number.Value
[code]...

I'm making a database that so I can log calibration information about equipment every year.I have 2 tables:
The Equipment details table
The Calibration record table
ID Number is shared between the 2 tables so a calibration record can be linked to its' details.
For Example (simplified sample data):
Equipment Table
ID Item Unit Type
104 Thermometer DegC PT100
Calibration Table
ID Cal Point 1 Test Equipment Unit Under Test Date
104 20 21 22 06/01/15
What I want is a button on a form that creates a new blank record in my Calibration record table with the ID number already entered based on what record I selected in a combo box linked to my equipment table. I really don't know where to start.

I want Access to automatically generate a reference number for a record based on the values in on two other fields for a given record using a form.
The first field is called Operation Number.
The second is Bag Number.
The reference number needs to be in this format: 19C.3.1
Where 19C is the Operation Number, 3 is the bag number, and 1 is automatically generated. Additionally I need the last number --the automatically generated one--to go back to 1 if with each new bag number.
This is kind of like library catalog numbers. Not sure how to do this.

I have a subForm set to continuous forms. I need a field called txtStatusDetails required (cannot be null) if the field txtDutyStatus = "Not Available"
Here's what I have so far:
Private Sub Form_Current()
' This procedure runs after the record changes.
On Error GoTo Err_Handler
ResetAvailability
Exit_Proc:
On Error Resume Next

Simple example is I have say 3 recordsets open (they are opened once as they are refered to many times) - they are open early in the form (in this example 3 price lists that are applicable for a customer) (if the syntax of the select is slightly wrong I'm just showing to 'prove' the concept).
Dim db As Database
Dim rs1 As Recordset
Dim rs2 As Recordset
Dim rs3 As Recordset
Set db = CurrentDb()
Set rs1 = db.OpenRecordset("SELECT * FROM Prices WHERE (((Prices.ID)=1));")
Set rs2 = db.OpenRecordset("SELECT * FROM Prices WHERE (((Prices.ID)=2));")
Set rs3 = db.OpenRecordset("SELECT * FROM Prices WHERE (((Prices.ID)=3));")
What I want to do is have a central function that I can pass a list I wish to process/do something with aka. The 3 recordsets are the same except for the where criteria.
private sub GETPRICEFROMLIST(pricelist as long)
dim rs as recordset
set rs = Recordset("rs" & pricelist)
.....
I put the above to show what I'm trying to do but of course that doesn't work There won't be any updates to these recordsets only reading of data.

I have 2 similar numbers in a table with the following parameters:
Double, Fixed, DecPlaces = 2
One number (GLminor) = 0.10
Second Number (GLmaj) = 0.50
When i use the following code to create and pull the numbers from a recordset the (Gmin) is OK and displays as 0.1 but the (Gmaj) has a problem and displays as 0. So when i'm attempting to use it in an equation (OtherNumber) / (Gmaj) i'm getting a divide by zero error.
Code:
sSQL1 = "SELECT * FROM tblRScales WHERE ID = " & RScaleID
Set rs1 = CurrentDb.OpenRecordset(sSQL1, dbOpenDynaset)
rs1.MoveFirst
Gmaj = rs1!GLmaj
Gmin = rs1!GLminor
I've tried using CDec(OtherNumber) / CDec(Gmaj) and still get the same error.
As both numbers have the same properties in the table parameters i'm completely lost as to why one seems OK while the other seems to round down to 0.

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 am currently developing a calendar and am trying to open a recordset based off of a SQL string. When I deleted the Where part of the SQL statement, the code ran fine. So I am pretty sure that the problem lies within the Where part of the code. I use this code to filter my query based on txtTaskTypeID but if the value is null then the query is suppose to return all values. I keep getting Run-time error"3061: Too few parameters. Expected 1".
Code:
strSQL = "SELECT tbl1CalendarEntries.ID, tbl1CalendarEntries.Title, tbl1CalendarEntries.StartDate, tbl1CalendarEntries.StartTime, " _
& "tbl1CalendarEntries.EndDate, tbl1CalendarEntries.EndTime, tbl1CalendarEntries.TaskTypeID " _
& "FROM tbl1CalendarEntries " _
& "WHERE (((tbl1CalendarEntries.TaskTypeID)" _
& " Like IIf(IsNull([forms]![frmProductionPlanning]![txtTaskTypeID])=True,""*"",[forms]![frmProductionPlanning]![txtTaskTypeID]))) "
& "ORDER BY tbl1CalendarEntries.Title;"

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]

Date of Birth (DOB) field etc. in one program are text - how do I make another file with the same data into number fields for Date of Birth field etc? When I copy data to file that has number fields the 09252004 is changed to 9252004. Can I get reports with the correct Date of Birth in them by moving data from text file to number file?
There is data entered monthly in file and formula has been set up for January, February etc as ---quarter: Int(([month]-1)/3)+1. I would like formula for the fiscal year for April to be counted as month 1, May - month 2, June as month 3, July as month 4, August as month 5, Sept as month 6, October as month 7, Nov as month 8, Dec as month 9, Jan as month 10, Feb as month 11 and March as month 12.
Thank you

Why my Recordset start from record # 301 instead of # 1 Here's part of my code:
Set db2 = CurrentDb
Set rst2 = db2.OpenRecordset(strTable2)
If rst2.RecordCount = 0 Then
MsgBox "No records to process."
[Code] ....
Table has 12,000 records and the first record has an ID of 1. So why is it starting from the record 301? What am I doing wrong?

I am trying to lookup a record in a recordset. If no match is found then run an append query. I am having trouble coding the findfirst syntax.
Code:
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim WO As String
WO = Forms!frmdsh_workorder!txtWO
Set db = CurrentDb
[Code] .....
When I run the Function, it throws a RT error #3077 on the .findfirst line. (Syntax Error (Missing Operator) in expression. )

I have a DAO.recordset called "rsSQLIn". This comes from a csv file by:
Code:
strSql = "SELECT * " _
& "FROM [Text;Database=" _
& strFolder _
[Code]....
While the validation runs a boolean keeps track of validated input and errored input.
After validation the validated input is dumped in the table.
Now what I want is de saving the errored record from "rsSQLIn" to be copied to a new .csv file.
The problem I have is that I cant seem to get the current record from the recordset "rsSQLIn". How do I reference this? I need the complete set of 24 fields being the same within "rsSQLIn"

I am attempting to use 2 fields from a query to supply the Top and Left Properties of a Collection of Rectangle Controls on my form. The purpose of this is to display the locations on a map of "Spots" in a haunted house. The query that I am using shows the spots that have been pre-tagged with the location of where they belong on the map (currently the query has only 24 tagged spots). On the actual form I have rectangle controls (control type acRectangle) with their visible property set to False by default, named box1 through box25 (there will be more eventually, as I am just working with this test group).
I started with the following code, yet it stops after (correctly) placing the first spot on the map (please see the attached jpg):
Code:
Private Sub Form_Open(Cancel As Integer)
Dim ctl As Control
Dim db As DAO.Database
Dim rst As DAO.Recordset
[Code]....
I'm sure I need to have 'Loop' in there somewhere, but I am not sure exactly where to place it, or if another line is also needed.

I have a problem with trying to execute a command for each record in a recordset. What I'm trying to build is a file distribution system. I have a form with the path where the source file is and a subform with a couple of records where the destination path is defined. I use the code you will find below, but it will only copy the file to the destination from the first record.So the code will do the filecopy command for every destination.
Code:
Dim Sourcepath, Destinationpath
Sourcepath = Forms![Item distribution]![Item source path]
Destinationpath = Me.Destination_path
Dim rs As DAO.Recordset
Set rs = Me.Form.Recordset

Is is possible to generate a workbook for each record in a recordset, and title it using the unique identifier for that record?
I created the following code, but it does not seem to work. First of all it doesnt like the string and secondly it does not like the declaration of wb as Excel.Application
Code:
Private Sub generate_wkbk()
Dim rsID As DAO.Recordset
Set rsID = CurrentDb.OpenRecordset("Select * FROM tblMeeeting;", dbOpenDynaset)
With rsID
rsID.MoveFirst

I am trying to copy a subform record set from one record to the next record. The data in the main table is copied over using this method;
Code:
Dim v1 As Variant
Dim v2 As Variant
Dim v3 As Variant
Dim v4 As Variant
v1 = Me![Today's Date].Value
v2 = Me!Insured.Value
[Code] ....
Can I integrate the copying of the subform data to the new record with this or do I need something different, and if so what?
It's a many to many relationship and I've tried adding the following line to the code:
v5=Me![Endorsements Umb XS].[UmbID]
same=v5
and it works but it only copies the first record out of the set.

Is there a way to print the current record from a dao.recordset?
This is an exercise to compare data content.
I have a table with 30 fields and thousands of rows (rs1).
I'm comparing it with a copy of the same table (rs2) that has the same number of fields and the same rows and almost the same content.
I can loop through the recordsets and get the cursor to stop on a field whose values don't match, lets say on row #x
and the programmed message will say something like:
"ROW: 699 Field: [RequestStatus] rs1.VALUE: Closed, DOES NOT MATCH rs2.Value: VOID, in the comparison recordset"Then I'd like to print the entire Row, Row #699.
I thought I could use rs1.getrows but I'm not sure how to make that work.

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 linked table to a DB2 database. this table contains key-pair values and has about 140k records.
I use a Sub to update the value of a specific record.
The sub starts by opening the needed DAO recordset
Then it uses the rs.Findfirst method
It checks if rs.Nomatch is not true (so the records exists!)
Then it starts updating the record with
rs.edit
rs!value1 = myvalue1,
rs!value2 = myvalue 2
rs.Update
There is where I get the '3021 No current record' error
I use the same sub on the same table to update to different parts. One part works the other gives me the error.
I have checked for typos.

Special situation: The SQL Server Linked Server across the country is linked to a Read Only Oracle DB. This data pull works perfectly and populates the Subform.
The problem is that Oracle can take 3 to 6 seconds to retrieve the single record depending on the network traffic through a small pipe.
The code below shows the RecordSource for the SubForm. clicking on a list box supplies the value. Then 3 to 6 seconds later, the subform populates.
The actual Recordset for this Recordsource is needed to conduct Validation on each field. Normally this would be on SQL Server, I might just create a Recordset Oject and run this SQL statement again in 1 milisecond. In this case, it will probably take an additional 3 to 6 seconds. Avoiding another lengthy round-trip to Oracle would be prefered.
Goal: How does one grab, clone, or other wise reference the existing recordset for the SubForm?
Note: Immediate Window - One single field can be returned quickly
There are 48 fields that need validation - is there a way to reference the entire recordset?
Immediate Window during Break Mode:
? me.fsubsrNavSHLBHL("NavSH_QQ")
NESE ' this is the correct value for the current recordsource
Set a breakpoint right after the line:
fsubsrNavSHLBHL.Form.RecordSource = "Select * from vsrNavigatorSHLBHL where Well_ID =" & txtNavWellID.Value
Immediate Window:
? me.fsubsrNavSHLBHL.Form.RecordSource
Select * from vsrNavigatorSHLBHL where Well_ID =91229
