Queries :: Calculated Field Is Blank For Records With Even Primary Key
Jun 17, 2013
I have a calculated field in a query. The field name is TotatPt (this is to calculate the total points students have earned during the term). The expression is as follows:
Code:
TotalPt: [Att1Pt]+[Att2Pt]+[Att3Pt]+[Att4Pt]+[Att5Pt]+[Att6Pt]+[Att7Pt]+[Att8Pt]+[Att9Pt]+[Att10Pt]+[Att11Pt]+[Att12Pt]+[Att13Pt]+[Att14Pt]+[Att15Pt]+[Att16Pt]+[Att17Pt]+[Att18Pt]+[Att19Pt]+[Att20Pt]+[Att21Pt]+[Quiz1Pt]+[Quiz2Pt]+[Quiz3Pt]+[Quiz4Pt]+[Quiz5Pt]+[Quiz6Pt]+[Quiz7Pt]+[Quiz8Pt]+[Quiz9Pt]+[Quiz10Pt]+[MidtermWritPt]+[FinalWritPt]+[Proc1Pt]+[Proc2Pt]+[Proc3Pt]+[Proc4Pt]+[Proc5Pt]+[Proc6Pt]+[Proc7Pt]+[Proc8Pt]+[Proc9Pt]+[Proc10Pt]+[Proc11Pt]+[Proc12Pt]+[Proc13Pt]+[Proc14Pt]+[ProcPracPt]
I think this should be no complicated expression (though a bit long) and should just add the fields together. But what I get is that the calculated field appears as expected for records with an odd primary key (1, 3, 5, 7, ...) and turns out blank for records with an even primary key (2, 4, 6, 8, ...)!
I've attached a screenshot.

I have a query by form that has the criteria Like [Forms]![FormName]![ControlName] & "*" for each field. However the problem is that if one of the records have at least one blank field then the whole record wont show up in the query results. For example if there is a record with Fullname, and Age filled in but Address isn't filled in then if search Adam into the query by form the record wont show up because the address line is blank.
To make records that have a blank field show I know I could use Like Forms![FormName]![ControlName] & "*" Or Forms![FormName]![ControlName] Is Null but when I have used it, it has corrupted the query because I think if you use If Is Null many times in one query it becomes too complex for it to process.
Also, The other method is to use Nz in an expression but I cant do that because I want the query results to show up in a form where you can edit the records and the error message Field is based on an expression and can not be edited comes up if you try to edit the records. Anything else I could put into the criteria to show records that may have a blank field?

All. Using access 2010. I have a query that returns 92 records. When I put in the criteria for one field to leave out records with “approved” which totals to 9 records, the query only returns 10 records. It is not returning the records that are blank(not null) for that field. I want those records. Why is this happening and how can I get the blanks for this query?

I am working with an inherited database. When this database was created, a large amount of data was imported. Over the course of time, I have added additional fields for tracking information. One such field is "Date Started."
Unfortunately, there are almost 500 records without this information and that is skewing some report results.
I would like to do is insert the date of 9/9/1999 into all records that have no data in this field. (This date is well before the creation of the database and would serve to indicate old records, whether or not they are still active.) Copy and pasting isn't working, and I can't do a find and replace, since there's nothing to find.

I want to take the sum of all records 'cost' i.e.
record 1 - 2
record 2 - 4
record 3 - 3
I want to take the sum and put it in a calculated field and use it to divide it by a predefined value 'no of responses.'
So I make the field in the query -> Calcfield: (Sum([cost])/[responses])
I am pretty new to this and i don't understand why this won't work? Is it something to do with the row Group by (total.)

I am putting the finishing touches on a DB and have come up with a a problem which I cannot solve. I have code on my data entry form that concatenated the days and times of up to five days. That is : [Day1] & " " & "@" & " " & Format([Time1],"h:nn AM/PM") & " " & ";" and so forth for five days. It has a complicated (for me) nested IIF statement and it works fine on the form. But I have now transferred the data from an old DOS DB and I do not want to go through almost 5K records just to update three fields.When I tried to do it in an update query, it said that the string was too long for the update. My update is:
IIf([Day5] Is Not Null,[Day1] & " " & "@" & " " & Format([Time1],"h:nn AM/PM") & " " & ";" & " " & [Day2] & " " & "@" & " " & Format([Time2],"h:nn AM/PM") & " " & ";" & " " & [Day3] & " " & "@" & " " & Format([Time3],"h:nn AM/PM") & " " & ";" & " " & [Day4] & " " & "@" & " " & Format([Time4],"h:nn AM/PM") & " " & ";" & " " & [Day5] & " " & "@" & " " & Format([Time5],"h:nn AM/PM"),IIf([Day5] Is Null And [Day4] Is Not Null,[Day1] & " " & "@" & " " & Format([Time1],"h:nn AM/PM") &
[code]...
how to update the table if a field is blank without clicking through all 5K records? I have tried simple concatenation, but I usually get a lot of extra @ in the field.

I want the field to be subject + catalog + topic no. The only problem is that there is not always a topic no.
How would I write this expression?

I'm having an issue getting my query to omit records with a blank field - in fact, it omits all records.
What I'm trying to do is:
I have a list of customers, with phone and email addresses. I want to filter via query for only customers with their email address's entered.
Here is what I have:
IIf([Forms]![AdvancedReporting]![Check230]=-1,"*",Null)

I have the following calculated field in a query:
LoanNo:IIf([Stats].[LoanCnt]>1,[Stats].[LoanCnt] & " Loans",[Loan].[LnNo])
Within its query, it correctly displays the loan number associated with a particular loan.
However, when I run a second query
SELECT LoanNo
FROM qryLoanInfo
it comes up blank for every record (other fields are OK)
Does anyone have any idea what might be happening?

I have a couple different reference files that get updated each week. Sometimes there are missing data elements, so I'd like to structure a select query to show me those records that have blank elements but I'd like the similar records to be pulled in as well, so I can make a determination as to how to populate the blank records..
See attached example: I have a client ID reference table that gets populated with forecast owner names (individuals responsible for the customer) from a couple of different sources. Sometimes there are names attached and sometimes the field is blank.
How can I structure a query to show me just those Client ID's that have multiple entries with blank AND non-blank forecast owners? I'd also like to exclude single/multiple records where there are only blank records...

I'm working with a report that totals the number of times a topic is returned from a query. If a topic is not returned at all, i don't want it to show at all. Currently it is showing a blank field for that topic name and blanks in the count as well. Here's the filter i've put in to pull the right data out of my query: =Sum(IIf([Caller Used Resources]="No",1,0))

Access 2010 database.
I am trying to get an average from several numbered fields, which some may occasionally be blank.
=Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0)
I get an error message that says "The expression =Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0) cannot be used in a calculated column. This is a hypothetical expression being used.
The real expression is ...
([GC A1 - 2]+[GC B1 - 2]+[GC C1 - 2]+[GC D1 - 2]+[GC E1 - 2]+[GC A2 - 2]+[GC B2 - 2]+[GC C2 - 2]+[GC D2 - 2]+[GC E2 - 2])/10
This expression works great until a field is left blank, and then the average box is left blank.
The fields I am trying to add are Long Integer. Would that affect it?

(Phone usage report) I have 3 queries, Query 1 counts number of calls in for a phone extension. Query 2 Counts the number of calls out (dialed calls). The information is keyed on the phone extension. Query 3 runs the first 2 queries (By date via parameter). Each query is keyed on Extension, I only want to see the number of calls in and out for each extension. Problem, when a phone extension being counted has no calls (In or Out), it leaves the phone extension out of the report. I want to see all the phone extensions info regardless of the count (if it = 0). Does anyone know a way around this? Thanks in advance for your help.;)

OK, I've tried everything I can think of with this query/subform/records problem. I've searched the internet for days, even bought some big fat Access reference books and read them cover-to-cover, but I still can't get my database to do what I want. This newbie would *really* appreciate some help...
I am trying to create a database which I can use to store clients advertising expenses. I currently have three tables: tblListings (which stores basic information about each client, with the field ListingID as the primary key); Advertising Rates (which stores the different types of advertising products and their prices, with the field ProductNumber as the primary key); and tblAdvertisingExpenses (which stores each order of an advertising product, including the clients ListingID as a foreign key, date, the type of advertising, and the total cost - the primary key is an auto-numbered field called OrderNumber).
I have a main form called frmListings, which displays the clients information from the tblListings table, and includes a subform. I wanted the subform to show only the advertising expenses corresponding to the ListingID (ie. client) displayed on the main form, so I based the subform on a query which displays all records from tblAdvertisingExpenses with a ListingID that matches the ListingID displayed from tblListings. So far so good - the records displayed in the subform change correctly when the record in the main form changes.
Now the tricky part
The subform displays a blank row for a new record, and I would like to be able to enter a new advertising expense in that blank record (date, type of ad, and cost), and have that data added as a new record in the tblAdvertisingExpenses table with a new auto-numbered OrderNumber. I dont know whether its because the subform is actually a dynaset from a query, or because Ive constructed the query incorrectly (highly likely, Im still pretty new to queries), but when I add in the details for the new record, I get the following error:
The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship (etc, etc).
I suspect that Access is attempting to write the record (along with the ListingID) back to the tblListings table, where the same ListingID already exists (uniquely) as the primary key. But I dont know for sure, because I dont really know what the heck Im doing. What I actually want to do is have the new record Ive entered in the subform added to the tblAdvertisingExpenses table, which is the record source for the qryListings query which displays records in the subform. It shouldnt be a problem, should it? So why cant I get it to work? Perhaps theres a fundamental flaw in the way Ive broken up the database into tables, or my assigning of primary keys and foreign keys. Or perhaps theres a flaw with the way Ive constructed my query. Or am I forced to have a completely separate form solely for entering data into the tblAdvertisingExpenses table? Or will I need to use a macro or VBA to accomplish what I want?...
Sorry if this is terribly confusing. I can provide more specific details (and screen captures) of the tables, queries, forms, and relationships (if I havent provided enough specific details already), and would really appreciate any help that anyone can provide. Help?!

I have two tables: Table #1) [Request Table] Customers request our company to stock a certain Part Number with a minimum value. Ajax - P/N "NP4i" - Min "30".
Table #2) [Sales History] All sales purchased and the "Qty-Total" purchased. For simplicity Fields are limited.I created a CrossTab Query that displays from [Request Table] P/N's requested/ min values (Row Headings) then showing P/N's purchased [Sales History] Value="Qty-Total" Sum and
Column=Format([Invoice Date],"mmm/yyyy") group by, showing last twelve months.
Ex: Customer name, Part Number, Minimum, May/2013, Apr/2013, Mar/2013 and so on.
AJAX, NP4i, 30 4 21 5 and so on.
The Crosstab query list only requested Part Numbers that have at least One sale wihin the last twelve months.If there are NO sales, the crosstab query will NOT show this Part Number.My boss wants to see the requested Part Numbers that were never purchased along with the ones purchased.He wants to address the NO sales, yet they requested we stock that particular Part Number for them.
Is there any criteria I can use to force the Part Number field on the [Request Table] side to populate even though there were NO sales within the last twelve months?

I have a table of the following structure:
Key 1 Key 2 Key 3 Optional
data1 data2 data3 data4
The 'key' fields are a composite key of primary key fields from other separate tables. I have a form that generates a new 'Key 1' record and I would like to make a query that creates all possible 'Key 2' and 'Key 3' results (new combinations) while key 1 stays the same. How would I go about doing this? I know I can be done.
I cannot really give any real data as I haven't received it yet.

I have a query which selects a material ID and material name from one table and the associated manufacturer, supplier, and packaging type from three other tables. Some of the manufacturer, supplier, and packaging data were imported from an Excel spreadsheet and did not have data for those fields, so those fields are blank. When I run the query, I only get the records which have all fields filled out. How can I get the records where the material ID and material name are filled in, but the manufacturer, supplier, or packaging type are blank? Here is the query I'm using currently:
Code:
SELECT tblMaterialSpecifications.ID, tblMaterialSpecifications.Critical, tblMaterialSpecifications.MaterialSupply, tblManufacturer.Manufacturer, tblSupplier.Supplier, tblPackaging.PackageType
FROM tblPackaging INNER JOIN (tblSupplier INNER JOIN (tblManufacturer INNER JOIN tblMaterialSpecifications ON tblManufacturer.ID = tblMaterialSpecifications.ManufacturerID) ON tblSupplier.ID = tblMaterialSpecifications.SupplierID) ON tblPackaging.ID = tblMaterialSpecifications.PackagingID
WHERE (((tblMaterialSpecifications.ActiveInactive)=-1))
ORDER BY tblMaterialSpecifications.Critical, tblMaterialSpecifications.MaterialSupply;

I have a table for storing vehicles. The table contains the following fields:
VehicleID
Make
Model
Trim
Build Date Begin
Build Date End
Vehicle Name - a concatenation of 'Make' 'Model' 'Trim' 'Build Date Begin' and 'Build Date End'
The 'Vehicle ID' is the primary key, the rest of the fields can't be indexed with no duplicates. Is there a way of preventing one from saving a duplicate VehicleName on the table since it is a calculated field.

I have a query which returns a calculated percent. I have ordered that in descending order, and now want to see the top 50. So (In Access 2010) I entered 50 into 'Return'. But it returns all of the records!
Is this because pct is a calculated field? How can I correct this? The SQL seems to be correct.
Code:
SELECT TOP 50 HeciFail1.POHECI, HeciFail1.POQTY, HeciFail1.FAILQTY, IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) AS PCT
FROM HeciFail1
ORDER BY IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) DESC;

I have code that I want to cycle through several fields and check instead of coding for each individual field. I thought this might worked on an earlier project but Im lost. When I try to add my code in the "If MyControls Then", I want it to hide the field on a report if it is blank. It doesnt allow me to do MyControls.Visible.
Code:
If Len(Reports!RecallReport!QAW1 & vbnullsting) = 0 Then
Reports!RecallReport!QAW1.Visible = False
End If
but I want the below code to go through each field With QAW in it and hide it if it is blank.Or having it go through each field individual. There are 10 Fields With QAW THen there are another 10 fiels with ShipDist. I would prefer a simple solution to check all at once.
Code:
Dim MyControls As Control
For Each MyControls In Me.Controls ' Iterate through each element.
If InStr(1, MyControls.Name, "QAW") Then
If MyControls Then
End If
End If
Next
I don't even know if I am on the right track or what.

I have a query with a Date field for EndDate (the dates for end-of-week, Fridays in our case) and another field for Sales (number of sales, not dollars).I want to add 4 calculated fields that represent weeks and have the Sales appear in the correct column (field) for that date.So I will have columns for 10 July 15, 17 July 15, 24 July 15 and 31 July 15 and I want the Sales for each record to land in the correct date column, based on the EndDate column. (The 4 fields is just for the sake of the example, I will actually be having dozens of these calculated date fields).I tried to do it by setting up the 4 calculated fields like:
10Jul15: Sales
and then adding Criteria like:
EndDate = #10/07/2015#
It doesnt work.

I have a table (tblStats). The user enters his current weight in a field named Wt. There are 2 other fields in the table named WkLoss and TTDLoss. These two fields are intended to be calculated. What I am trying to do is when the user enters his current weekly weight figure into the Wt field, I want the field WkLoss to get the user's weight from the previous record and place the difference in the field WkLoss. Also I would like to keep a total to date in the TTDLoss field.
So far this has been my attempt.
Code:Public Sub setWeight()Dim rs As DAO.RecordsetDim Startval As DoubleStartval = 190Set rs = CurrentDb.OpenRecordset("tblStats")'Select records to be updatedSet rs = CurrentDb.OpenRecordset _("SELECT * FROM tblStats ") rs.MoveFirst Do rs.Edit'field to update rs.Fields("WkLoss") = Startval rs.Update rs.MoveNext'increment step value Startval = WkLoss - Wt Loop Until rs.EOF rs.Close Set rs = Nothing End Sub
All I get is the value 190 placed in the first record and all zeros in the subsequent records. Also I don't have a clue as to how to get the Total To Date field to calculate.
Any help would be appreciated
Thanks for your time.
