Modules & VBA :: Update Field With Calculated Result
Mar 19, 2014
I am trying to update a field with the result of what is in the field plus the contents of a unbound form field.
So if crm_order_det.Qty contained the number 5 and the form field (labelled qty) contained 7 I would like the field crm_order_det.Qty to end up with 12.
The code I am using
sql = " Update crm_order_det SET [Qty] = (" & _
frm!Qty + crm_order_det.Qty & ") where crm_order_det.part = '" & frm![SearchResults] & _
"' and order_id = " & frm![order_id] & ";"
DoCmd.RunSQL sql
However I get the following error
Run-time error '424': Object required.

I have a query that returns several calculated fields. One of them is simply derived by simple summation of the others. If this calculated field returns a negative number, I need it to show as a zero.
The only way I know how to do this is by an IIF statement :
Code:
SELECT [fld1], [fld2], [fl3], .....
IIF(([fld1]-[fld2]-fld[3])<0,0,([fld1]-[fld2]-fld[3])) AS fld4
FROM...
(The above doesn't suggest that [fld1], [fld2] etc are calculated fields - I just wrote it like that for succintness - they calculate fine, there's no issue with them...)
Is there a more efficient way of doing this? I find IIF's a bit tardy, possibly because they evaluate for both True & False eventualities, regardless of the condition, and this query is going to run against a fairly large dataset so any performance lag is going to be exacerbated.

I have a created a query which I want to update a table. The field is called DTP. I have the Workingdays2 module in place as well as the Holidays Table. The dates (date only) are called Time in and Transaction date. I want the table to update records only if the entry in Completed is Yes. I have attached screenshot of what I have in query. I am no good whatsoever at VBA so I used the Query design view. It shows how many records will be updated (which is a valid number) and shows me which field will be updated. However when I run the query and then opend the Table the DTP field is empty.

I got a problem, I have a calculated field which is sometimes empty due to no information being put there. Here is what I have in the afterupdate code:
FUTURE DATE = Me.Box123
The Box123 is my textbox and the FUTURE DATE is the datasource field.
When the field is blank I get the following error message:
I get a Run-Time Error "2113";
and the message "The value you entered isn't valid for this field"

I've read over and over that calculated data is bad, that's fine with me... but here is my dillema...
I have four fields that interact with my calculation in a single form. There is only one table in the database.
AmountF (The stored data in the table) (amount financed)
FC (calculated by =[amountf]*.25) (finance charge)
Amount Paid (used in calculation of total due)
total due (calculated by =[amountf]+[fc]-[amount paid])
The math already works, everything works. I can choose to print the form and it looks great. However, I would like for it to (when I'm done printing the form) somehow save the total due data to the AmountF column in the table. AmountF is in the same line as all the other information, so I would like it to not create a new record just update the old one.
All four of these fields have a text box in the form for themselves.

I have a subform embedded in a main form, the subform has a field (text box) that is doing automatic calculation so no manual entries are needed from the user. I have tried to pass automatically the final result to a text box in the main form, but all events are not working (afterupdate, On change, On Dirty), etc.
I have a button to do the above mentioned in the main form, but I don’t want to use that button, I want to do all the process from the subform.
Also, from the subform I was able to do click on the button on the main form (programmatically), however MS Access is too quick and the value extracted from the subform is always empty (zero); Acees is finishing before the calculation is done.
I am using MS Access 2010.

I have a database to track temporary decertification's. I have the expiration and max dates calculated out from the original dates at the top of each box. The temp expiration date is calculated by adding 267 days from the first date . When we enter an extension, the new expiration date is 30 days from the extension date. My question is, how can I make the expiration date update when a new extension is put in.
For ex.
Temp Decert Date: 05 Dec 2014
Temp Decert Extens 1:
Temp Decert Extens 2:
Temp Decert Extens 3:
Temp Experation Date: 31 Aug 2015
Max Temp Date: 04 Dec 2015
how can I make the expiration date update to go 30 days from what is in the extens field 1, 2, and 3 (respectively) instead of 267 days from the original date?
So I want it to look like this after updating a field
Temp Decert Date: 05 Dec 2014
Temp Decert Extens 1: 30 Aug 2015
Temp Decert Extens 2:
Temp Decert Extens 3:
Temp Experation Date: 29 Sep 2015
Max Temp Date: 04 Dec 2015

G'Day all, I am new to the forum family so please excuse any ignorance I may have in asking questions the right way.
The following at times depending on certain values creates a negative value.
WDCCFrm: [qry Areas]![Formation Value]-([qry Areas]![Formation Value]*((100/[qry Areas]![Formation_DesignLife])/100))*(DateDiff("yyyy",[BLOCK_DATA]![YEAR],Date()))
Due to the data requirements a negative value is not acceptable, it needs to be zero. The above is part of an Asset Managemnt Program and if the WDCC (Written Down Current Cost) is 0 then the item is written off. How do I change the negative value to a zero.
Any comments or suggestions would be appreciated.
Regards
Alrae1

I am working with Access 2010, on vista. What I have is a query made up of two tables, one product the other inventory. (see below) query.jpg
In the product table i have a field called "minimum reorder level". In the inventory table i have two fields one called "number in stock" and "number on order". What i want to happen is "number on order" to be filtered by the result, if the "number in stock", is less than "minimum reorder level", if it is, have the result placed in the "number on order" field. EG. if the "number in stock" = 2 and the "minimum reorder level" = 5 then 3 would be placed in the field "number on order" and only the second record from the query would be visible (see below) Query result.jpg The result of this would mean that the field "number on order" would be populated with the result and the and query would also use this to filter the record.

I am trying to use a calculated field in a recordset but I am having problem with the script trying to compile.
my record set is
Set rstPrice = db.OpenRecordset("SELECT Period_desc, Price, Round(Price/7,2) AS Daily_rate FROM qryPropertyPriceList WHERE [Our ref] = '" & rstProp![Our Ref] & "' And [Year] = " & rstProp![Next year price base] & " Order By Sequence", dbOpenSnapshot)
The calculated filed I have added in is Round(Price/7,2) AS Daily_rate
If I let it run just with this it runs fine.
and then I try to use this calculated field:
Do Until rstPrice.EOF
Temp = Temp & rstHTML!html35 & rstPrice!Period_desc & rstHTML!html36 & rstPrice![Price] & "-" & rstPrice![Daily_rate] & rstHTML!html37
rstPrice.MoveNext
Loop
rstPrice.Close ' Tidy up
Set rstPrice = Nothing
They it stops running and it all seems to be because of the Daily_rate field

I'm new to programming with Access but am attempting to create a new field in a table with an new date based on existing fields in the table.
The current fields are [Frequency], integer, [Risk], text, [Last Audit Date], date/time, and the new field is [Next Audit Date]. [Frequency] is a calculated field based only on [Risk] and is equal to "5" if [Risk] is "Low" and is "3" is [Risk] is "Medium" or "High", and [Frequency] is blank if [Risk] is (thus far it has never been empty).
What I need the new calculated field to do is return "N/A" (or blank, or anything easily separated really) if [Frequency] is blank, or if [Risk] is "Low" or "Medium". If [Risk] is "High", [Next Audit Date] should be equal to [Last Audit Date] plus 3 years. When I try to save the code, I get this message: "The expression could not be saved because its result type, such as binary or NULL, is not supported by the server."
This is my code now:
IIf(IsNull([Frequency]),"",IIf([Risk]="Low","N/A",IIf([Risk]="Medium","N/A",IIf([Last Audit Date]="N/A","N/A",[Last Audit Date]+Year(3)))))

Is it possible to add/edit a record from a DAO querydef that has a calculated field in.
Code:
Set qdf = db.QueryDefs("qryOutput_" & strDept)
qdf.Parameters("Enter Date") = dDate
Set rs = qdf.OpenRecordset()
Using the rs.Edit or rs.AddNew worked fine until I put a calculated field in the query.
The calculated field is just a total of some fields in the table.
I thought this was something to do with dbOpenDynaset but it just keeps having the same error
Cannot update. Database or object is read-only.

I am looking for a way to add a calculated field to the end of an existing query using VBA. Is there an easy way to do this?
The data I receive from an external supplier shows monthly data split by column with a new column added in each month. I then need to reflect this by adding a new column to the end of the query. It is currently a manual tweak, but I want to automate this with code.

I have the following fields in an A2010 form
PaymentMethod
Total
InstalmentAmounts
OurFee
InstalmentAmounts field is populated based on the results of PaymentMethod which is a combo box
Here is the current code
Select Case Me.Payment_Method.Value
Case "Three post dated Cheques"
'If three payments by cheque
Me.InstalmentAmounts.Value = Round(Me.Total.Value / 3, 2)
In some cases there will be a few pennies that the client "overpays" because the instalment amounts will not add up to the Total. I need to add up the TotalInstalmentPayments to find out what the client actually pays and then add the difference between TotalInstalmentPayments and Total to the OurFee field
So
Total = 500.00
Payment Method = 3 instalments so
IstalmentAmounts = 166.67 (rounded) so client pays 500.01 so the 0.01 needs to add to the OurFee field.

I am creating a form for 3rd-party service contracts, and I have two tables called tblServiceProviders and tblServiceDescriptions. tblServiceProviders has a 1-to-many relationship with tblServiceDescriptions; i.e., each Provider can have multiple Descriptions (real world: product offerings). So for example, ServiceProvider "Acme Corp" might have ServiceDescriptions "AcmeCare", "AcmePremium" and "AcmeInstall". My database is normalized, so tblServiceProviders has an ID field that is related to a field called ProviderID in tblServiceDescriptions.
Each ServiceContract includes, in addition to customer name and some other stuff, one and only one ServiceDescription. The ServiceDescription field in the ServiceContract form is a drop down box called comboSvcDesc and it contains all of the ServiceDescriptions in the database. I also have a non-editable text field on the form called txtSvcProvider.
What I want is to have the name of the ServiceProvider ("AcmeCorp") automatically populate in txtSvcProvider whenever the comboSvcDesc box is changed. So for example, if I change comboSvcDesc box from "WidgetCare" to "AcmeCare", I want txtSvcProvider to change from "WidgetCorp" to "AcmeCorp".My thought is that I should be running a SQL join query to get the related value "AcmeCorp",but I can't figure out how to make this work in VBA.

When I try to run a simple update query written in VBA I get no errors but the field that I am trying to update just gets a 0 instead of the appropriate ID that I am passing.
Code:
Function ExtractProjects()
On Error GoTo ErrHandler:
Dim db As Database, rs As DAO.Recordset, rs2 As DAO.Recordset, var() As Variant, i As Long, qdf As DAO.QueryDef, ii As Long
Set db = CurrentDb
[code]....
The funny thing is if I run the query itself it works by using a parameter query but when I try and run it like this all I get is 0's in the field that it's supposed to be updating.The field [(SDSK) Charges Master].PID properties are as followed and is a linked table:
Type: Integer
Indexed: Yes (Duplicates Allowed)
A debug.print of the results of the query trying to be ran is the follows:
Code:
UPDATE [(SDSK) Charges Master] SET [(SDSK) Charges Master].PID = 1 WHERE ((([(SDSK) Charges Master].[IBB Date]) Between #10/24/2014# And #11/19/2014#) AND (([(SDSK) Charges Master].[Charge Num]) Like '*BAA*' And ([(SDSK) Charges Master].[Charge Num]) Is Not Null));
As you can see it is providing a number to be set to but instead it just fills it in with a 0.

I currently have the sql below...
UPDATE tbl_Node_List INNER JOIN qryUpdate_P1 ON tbl_Node_List.Zip = qryUpdate_P1.[Zip Code] SET tbl_Node_List.[Date Sent] = (SELECT [MinOfAudit Date] FROM qryUpdate_P1), tbl_Node_List.[Date Recv'd] = (SELECT [MaxOfAudit Date] FROM qryUpdate_P1)
WHERE (((tbl_Node_List.Zip)="35243"));
but I get an err.msg stating the operation must use an updateable query.
What I am trying to do is update my dates in 'tableA' with the max and min values stored in 'tableB'. I have read some of the posts but still can't quite get it. As always all help is appreciated.

My query contains two calculated fields [TaxSavings1] and [TaxSavings2], which are based on some currency and number-type fields in one of my underlying tables.
I just created another field in my query which looks like: [TaxSavings1]+[TaxSavings2]. Instead of adding the two fields, it actually lumps the two numbers together. For example, if [TaxSavings1] =135 and [TaxSavings2]=30.25, it will give me: 13530.25. I need it just to simply add, i.e. answer of 165.25.
Does anyone know how to correct this? Thanks in advance.

I need to update a field with the contents of 2 other fields when exiting a record. The fields (ItemNo) and (LotID) need to create or update the field (LotCode).
i.e.: ItemID (GM-235), LotID (26) will result in LotCode (GM-235-26).
I currectly use a Update Query that uses the expression:
[products].[MasterPN] & "-" & [lotid] in the lotCode Field - "Update to".
Unfortunatly, I am using a button on my form that executes the query, but it updates all the records and although it runs very fast, I would rather have it perform this task automatically when I leave the record.

I have a main form and 2 subform. The first subform has a field for %. And the 2nd subform has series of checkbox (Checklist or error made by the student)
Because every checkbox will lower the mark from 100 to x points per checkbox.So, I want that, if the field is not set to 100 yet, then they will not be able to check any box in the subform.I tried, before update of the subform, etc, but none work properly.

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 table 'table1' which has various field including an ID field and a yes/no field. I then have a form based on a query originally derived from data in the original table. The form provides a list with some ID's with a yes and some with a no.
I'm trying to write a button code to convert all the no's into yes' for those ID's picked out by the query.
I've searched lots of sites and get that I need to set recordsets for both table1 and the forms' query but all my efforts crash or give an error.
I am looking for the right way to say .." for each ID in form set the yes/no field corresponding to the same ID in table1 to yes"
I'd attach my version ....
