I need the following to display a zero if a null value is returned:
SELECT tdsIndivData.dsReportID, Count(tdsIndivData.StaffID) AS CountOfStaffID
FROM tdsReportData INNER JOIN tdsIndivData ON tdsReportData.dsReportID = tdsIndivData.dsReportID
WHERE (((tdsIndivData.Availability)="75% Availability"))
GROUP BY tdsIndivData.dsReportID;
I have a query which based on some fields on a form should display a set of records. In case when the user doesn't specify anything in the combobox on the form (value=NULL) I want the query to display all the records (like "*"). For some reason when i put the following in the criteria of the query it returns 0 records instead of displaying all:
IIf(IsNull([Forms]![frmClassReport].[ClassName]),(([tblClassesOffered].[Course]) Like "*"),[Forms]![frmClassReport].[ClassName])
I tried: IIf(IsNull([Forms]![frmClassReport].[ClassName]),"class_name",[Forms]![frmClassReport].[ClassName])
... and that works properly. I tried several scenarios and pretty much narrowed the problem down to the use of "LIKE" which when used as specified in the first SQL statement doesn't return any records. What am I doing wrong?
Good day,
I have a query that returns hours of vacation time taken for each specfic day of the year. But if no time is taken on for example Jan. 19th, that date do not show up in the query. I am wondering is it possible to return all 365 days and display a zero,if nothing is booked for that day. Attached is the db.
Thanks
Chris
There are 3 main tables
tblDrawingRegister - stores information about construction drawings
tblDrawing Revisions - each drawing in tblDrawingRegister has one or more revision or version
tblVendorDrawingList - this table has a list of drawings numbers that correspond to the drawings in tblDrawingRegister.
The drawing numbers from the vendor table as provided as an 'extra' as some people are more familiar with this numbering system.
Now the issue is that there is a one-to-many relationship between tblDrawingRegister and tblVendorDrawingList. In the screenshot I've attached there are 14 drawing numbers that correspond to one drawing number in tblDrawingRegister. (This is because the main supplier has packaged 14 drawings as one with just one drawing number). When this is the case I want to display the drawing title from the Vendor table. Otherwise if should just show the title from tblDrawingRegister.
I have tried using Dlookup to show the title from the vendor table when there are dublicates in the vendor table. It didn't work and I think this would be really slow. I've tried a few other things too but to no avail.
I really hope that this is clear. I've attached screenshots of the query too.
Hi,
I'm trying to work out a formula in a query.
At the moment it looks like this:
Days on Hold: calcworkdays([on hold date],[off hold date])-1
Now i have a module thingy set up (calcworkdays) which works out working days. What this expression does, when theres an on hold date and an off hold date is work out how many working days something is on hold.
Now, problem is, not always is something on hold, therefore fields are often blank and then i get a result in query that says "#Error", but i want to use the answer to this expression in another formula, but when error is displayed it makes the other query show error too.
What I want is some sort of If statement or similar so that if no results exist to display "0". Can anyone tell me how to add this in?
I'm a total Access Noob, it took me forever to work out this working days thing (damn access for not being as simple as excel!)
I think my problem might lie in the way the function has been written. I think i might have to modify this to show "0", rather than "error"
This is what ive got in the function.
Public Function calcWorkDays(dteStart As Date, dteEnd As Date) As Long
Dim i As Long 'day counter
Dim dteCurDay As Date
'set i = 1 if you want the first date to count as a full day
'or i = 0 if you do not want the first day to count as a full day
i = 0
dteCurDay = dteStart
Do Until dteCurDay >= dteEnd
'check date against holiday table
If 0 = DCount("[HolidayDate]", "tblHolidays", "[HolidayDate] = #" & dteCurDay & "#") Then
'continue checking for weekdays
If Weekday(dteCurDay, vbSunday) <> vbSunday And _
Weekday(dteCurDay, vbSunday) <> vbSaturday Then
i = i + 1
End If
End If
dteCurDay = DateAdd("d", 1, dteCurDay)
Loop
calcWorkDays = i
End Function
Any help would be much appreciated!
Thanks
Hi All,
I have a field called PRICE and obviously it is a NUMERIC field as it need to perform calculations such as calculating Total Quantity * Price etc. At the moment the PRICE is inputted manually by the User on a Form and when it has no Price it is simple left blank.
What I wish to include is that on the REPORT when the field is empty it writes the text FOC instead of leaving it empty.
Can you please anyone suggest a way of doing this.
Thanks any help will be much appreciated :o
What I am trying to do is merge data from several tables into one query, based on user defined options through multiple listboxes. I've figured out the VBA for the union all for the different selections, my problem is I can't determine how to make it dynamic and skip over a select statement if the list value is null. My code looks something like this so far.
Code:
Dim db As DAO.Database
Set db = CurrentDb
Dim qdf As DAO.QueryDef
Set qdf = db.QueryDefs("Flex2")
[code]...
I have 3 queries, one generates a calculation for a phone extension, the other generates a calculation for another field for the same phone extension, in the third query, I am using the data from the first 2 queries to show the data side by side, but when I run the third query, if any of the calculations have a null value, it leaves the whole phone extension out. Does anyone know a way around this?:eek:
View 4 Replies View RelatedI have a form which a user can select upto 3 different options to search the main database.
The main table has:
RVA Date
Council
Introducer
PS NO
Period
Asset Description
Current Cost
SSAP21
Position
The three fields the user can search on is:
Council
PS No.
Asset Description
I have created 3 individual queries to find the records for each of the above, as the other two choices could be left blank.
Not sure if one super query can be done to show the records based on the user input (as I say one or two choices could be left blank).
So far I have managed to get a main query (based on the 3 other queries) to work on all choices made by the user except Asset Description with the other two left blank.
I have made relationships between the three queries on the main query. Linking Council,PS No. & Asset Description to each other.
Almost there, just need the main query to work on the user selecting Asset Description only.....
i have checked the forums and i know they kind of answer this question, but im not really sure where i am ment to write it!
I have two queries, which a third query subtracts the 1st query and 2nd query values and gives the end value. If the 2nd value is null, i get a null value at the end, as i need to change this to zero instead. i know i need to use nz (as seen in microsoft access help, and other places on this forum) but im not sure exactly where to put this on my query, and in which query.
Basically:
(qryCountpartNo.CountPartCode)-(qryTotalquantityallocated.sumofquantity) = qryTotalFree
both countpartcode and sumofquantity may be null at any time
Any help would be greatly appreciated!
Thanks in advance,

I have a query feeding a form. It displays Active Orders. So the SQL is:
Code:
SELECT Orders.[Order ID], Orders.[Employee ID], Orders.[Customer ID], Orders.[Order Date], Orders.[Shipped Date], [Order Price Totals].[Price Total] AS [Sub Total], Orders.[Shipping Fee], Orders.Taxes, [Sub Total]+[Shipping Fee]+[Taxes] AS [Order Total], Orders.[Ship Name], Orders.[Ship Address], Orders.[Paid Date], [Orders Status].[status name] AS Status
FROM [Orders Status] RIGHT JOIN (Orders LEFT JOIN [Order Price Totals] ON Orders.[Order ID] = [Order Price Totals].OrderID) ON [Orders Status].[Status ID] = Orders.[Status ID]
ORDER BY Orders.[Order ID] DESC;
It has worked for the past year. However today is gives me an Invalid Use of Null error and will not load.
I am having a query, where a few date records are null because of no entry or record, what a want that the field with no date entry to be come up with zero "0" .

I have a database from sharepoint which has 250 fields based on a survey. I imported the database into Access where I made 10 queries.
I want to know is there a way to display those 10 queries in one queries or in one form.
Given that some queries has result to display and others haven't yet.
Hi there, instead of blank fields in my crosstab query, and hence my report, i would like a standard comment, such as 'No Booking'.
My crosstab is something like this:
.........A...........B..............C............. D
1.......X
2.......X..........................X
3...................X............................. .X
(Ignore the dots, obviously)
Currently, when i try to open the report based on this query, it fails unless each column has data in it for at least one record.
I've tried using the Nz function but haven't been able to make it work. Thankyou in advance! :)
I am trying to alter this parameter to bring back all records if either beginningsalesrange or ending salesrange is left blank. I can't quite get it right.
Between [forms]![frmState]![BeginningSalesRange] And [Forms]![frmState]![EndingSalesRange]
I have a form that feeds information to a query which in turn sets up a report. For clarity i will list out in basic terms what I have
Input Form
- Check Box to activate/De-activate a text field [chk-active]
- Text field for a parameter [txt-Parameter]
the query has a column that has null values from the originating table. These values will be added a t a later date, but need to be queried and reported at some business intervals.
In the query criteria for this column, I have the following Criteria
Like IIF([Forms]![ReportGenerator]![chk-Active]=0, "*", [Forms]![ReportGenerator]![txt-Parameter])[/I][/I]
I have tried for the last 5 hours to figure out how to write the formula to be able to get the blank entries to show up as well but have had no luck.
I have a query which i need to get Zero as a result if NULL value. How Can i do this ? Present SQL code is as follows;
SELECT tbl_Impts_main.Bkg_number, Count(tbl_Impts_main.Bkg_number) AS CountOfBkg_number
FROM tbl_Impts_main INNER JOIN tbl_booking ON (tbl_Impts_main.Voyage=tbl_booking.Voyage) AND (tbl_Impts_main.Vessel=tbl_booking.Vessel) AND (tbl_Impts_main.Bkg_number=tbl_booking.Bkg_number)
GROUP BY tbl_Impts_main.Bkg_number
HAVING (((tbl_Impts_main.Bkg_number)=[forms]![frm_Export_data_entry]![bkg_number]));
In a query, how do I return a blank or null.
IIf([Field1]=[Field2],NULL,[Field3]
They are all numerical values that I need to format into percentages however Field3 could contain zero so I can't replace Null with zero. I simply want to return nothing if Field1 is equal to Field2.
I am trying to using an iif statement to pick up null values, but I don't know what to type in the function. I tried using "is null", but got an invalid message.
What value I should type in to get null value in the function below?
IIf([popi_r2a] is null","",[popi_r2a])
I have 1 query that connects 4 of my tables through a tracking number. I am trying to make it so the value (DStatus) from DTable will populate where a (DStatus) is provided, but where there is no (DStatus) the column is filled in with a (SStatus) from STable. There is always a SStatus for each tracking number, but not always a DStatus, where there is a DStatus, it is more accurate.
Can I do this all in 1 query, whether I have to make a new column within my query for this to work, whether I need to have my query output into a table first.
Is there something I could type into the Criteria field of my query.
I have tried using Nz([DStatus],[SStatus]), an Iif Statement, the IsNull function, etc with no avail.
I have always relied on Design View to create my queries, usually with great success, but in so doing, I have not become familiar with SQL view, so can't solve this problem:
I have a very simple query whose only function is to sum the payment amounts received for each contract number:
SELECT Payments.[Contract Number], Sum(Payments.[Payment Amount]) AS [SumOfPayment Amount]
FROM Payments
GROUP BY Payments.[Contract Number];
It is then used in subsequent queries to create an accounts payable report. It works great as long as at least one payment has been received on the contract, but if NO payments have ever been received, the Sum is actually null, so that record doesn't get included. I need a way for this query to return zero or currency zero 0.00 for all contracts with no payments yet, so those contracts will be included and the next query in line will see a zero.
In my search, it seems I need to make use of the IsNull function in my SQL (the check expression would be the sum of payments, the replacement value would be zero) OR I need to include a WHEN or WHERE in my SELECT statement above? I just don't know enough about SQL to make this happen .
I have a count column in this query, and i would like for it to return a zero instead of null if it doesnt find anything to count. Here's the SQL for the query.
Code:
SELECT Documents.Status, Count(Documents.Document) AS CountOfDocument
FROM [Request Details] INNER JOIN Documents ON [Request Details].Request_ID = Documents.Request_ID
GROUP BY Documents.Status, [Request Details].Contract, [Request Details].CDRL, [Request Details].Change_Cycle
HAVING (((Documents.Status)="No Record") AND (([Request Details].Contract)=[Forms]![Report Runner]![Contract]) AND (([Request Details].CDRL)=[Forms]![Report Runner]![CDRL]) AND (([Request Details].Change_Cycle)=[Forms]![Report Runner]![ChangeCycle]));
After hours of playing around i finally have my IIF statement working the proplem is now is that when the Value is null it gives a blank value on my Report. How do i get it to show the value of 0 when it is Null. can i use an isNull withen my IIf statement maybe nested what is best practice?

As you can see I have tried two different ways but both don't work.
I have a table with two fields; Part and remarks - both Text fields containing 1.8 million records. Remarks field has 600,000 blanks in the field. I filtered for blanks to get the 600,000 records displayed. I want to update this field to N/A where null values exist. My code is
UPDATE PartApplications SET PartApplications.remarks = "N/A"
WHERE (((PartApplications.remarks) Is Null));
The query updates 55,000 records ONLY and leaves the remaining blank.WHY would all null values not get updated?
