Hi!
I want to add two columns a and b. However, there are rows in which EITHER a OR b is NULL. This should be handled as if the cell would be zero. Is there any way besides filling in 0s in the tables?
I tried
SELECT a, b,
IIF( a = NULL, b, IIF(b = NULL, a, a+b))
AS c FROM
but this doesn't work.
Any ideas?
Cheers
Tom

I'm developing a small Access 2007 database. I am looking for a dropdown list for one of the columns that would automatically reflect the contents of the previous 4 columns of the same row.
Sample table mentioned below. Column 6 (Winner) should be a dropdown reflecting the nominations1,2,3
Zone
Nomination 1
Nomination 2
Nomination 3
Nomination 4
Winner

I am trying to write a query that will select distinct values from three columns. The table name is Hoods. The columns are C1, C2, and C3. All three columns contain colors and can have the same values, but I only need to have a particular color selected once. For instance, all three columns contain "Black", but "Black" should only be listed once. The result of the query will be used in a drop down list.
The following works for one column:
SELECT DISTINCT [Hoods].[C1]
FROM Hoods
WHERE C1<>"";
Are there any suggestions?
Thanks
Having built a database that tracks projects across their lives, I've now been asked it I can identify the latest status of the project in a "quick view"
The table "All Projects" has columns that list the Project Number; Project Title; Project Manager and further colunms that list dates that the various stages of the project were achieved. i.e. Start Date; Date Milestone 1 Completed; Date Milestone 2 completed etc.
The projects are such that Milestone 5 may be completed before Milestone 2 and so on, so I need to be able to identify which Milestone was the last to be completed.
I thought of trying an IIF but the progress across the Milestones isn't logical so it won't work. I found something on the Internet about "Greatest" being used on some other program (not Access), which Access didn't like at all!
If the requirement had been given before starting building the db, I would have done everything differently, but I have no real desire to go back to stage 1 and start again, so how or if it's possible to find the highest / latest date relevant to the Project Number across the row of data ?
I have a listbox set to Multiselect property of Simple. The listbox is populated by using a table. There are 4 columns in the listbox
Code:
1 3/23/2014 4/5/2014 2014
2 4/6/2014 4/19/2014 2014
3 4/20/2014 5/3/2014 2014
The columns are PayPeriod, StartDate, EndDate, FiscalYear
What I want to be able to do is highlight a chunk of dates and have the first selected StartDate and the last selected EndDate populate two hidden text boxes so I can use them for my queries/reports.
I've tried a couple different ways. Each time what happens is it only uses the last item I have selected in it's calculations.
Code:
Dim ItemIndex As Variant
For Each ItemIndex In Me.lstPayPeriods.ItemsSelected
If Me.lstPayPeriods.Selected(ItemIndex) And Me.lstPayPeriods.Selected(ItemIndex - 1) = False Then
Date1.SetFocus
Date1.Text = Me.lstPayPeriods.Column(2, Me.lstPayPeriods.ListIndex)
End If
Next
In this example I tried to have it go through each Item of the listbox. I wanted to check to see if the current row was selected and the row before it wasn't. That way I could determine it was the first item selected in the group of selected items. It would always only use the last item I had selected.
Code:
Dim CurrentRow As Integer
Dim FirstDate As Date
For CurrentRow = 0 To Me.lstPayPeriods.ListCount - 1
If Me.lstPayPeriods.Selected(CurrentRow) Then
Date2.SetFocus
[Code] ....
I tried to do something similar with this code. Again, it only uses the last item I have selected.

Hi All.
I am running a select query on a date field.
I populate the table "date" field from a Microsoft Date and Time Picker Control 6.0(SP6).
I havent been able to figure out how to ONLY populate the date portion of the control so my field value containes Date & Time.
When I run the query, I have to select the day after my request to include the records I need. I think this is because of the time in the field
Example, If I want all records thru 6/17/2006 I must select "thru" 6/18/2006. This mucks things up if I have records dated 6/18/2006
Both of these statements give the same bad results:
Between [forms]![freports]![from] And [forms]![freports]![thru]
>=[forms]![freports]![from] And <=[forms]![freports]![thru]
Any ideas?
TIA

Hi there,
I have 4 fields in a table(Call_Freq, Call_Week, Call_Day, Call_Sequence)
I have to make a query that finds records with Null values in these fields.
If they are all null that is fine so I only want to return records with either one, two or three of the columns with Null values.
Any help would be appreciated.
Hey guys,
I'm doing a pretty basic query that
Selects about 5 fields
From Table1
Where
(value=0 AND name <> HOT)
OR
(value=Null AND name <>HOT)
I also have some records (4 specifically) that have a name = nullvalue. When I run this query it picks out all the records with a name, and skips HOT(which is correct), but skips the nulls which I also want to include. Can someone help me in finding the reason for this error?
I already posted this problem in the query section, but got no where with it... here is the problem now...
I have a form with three combo boxs - cboStatus - cboFunder - cboResource on my form. Depending on what you chose as an option the subform, which is based on a query will show the data with the chosen criteria.
Only the Status field is a required field, so there are lots of nulls in the funders and the resource fields.
In the all the fields I have "ALL" or "*" as an option.
So in the criteria in the query I use this...
Like fCboSearch (forms!form name!combobox)
This calls up this function...
Public Function fCboSearch(vCboSearch As Variant)
If IsNull(vCboSearch) Or vCboSearch = " " Or vCboSearch = "*" Then
fCboSearch = "*"
Else
fCboSearch = vCboSearch
End If
End Function
This works great to show me all the records or just records with a certain criteria selected, BUT BUT BUT I cannot get it to show my the NULLS, they are no where to be found. How can I change this to show me NULLS??
Thanks. Joye
I have a table which records are appended to in batch format. I would like to update a column called batch number for newly appended records with the Max of that column + 1 but I keep getting errors such as "operation must be an updateable query". Anybody have any suggestions. Mind you I am not doing this in VB or SQL formats, I use the query design format. Thanks, Jim
View 3 Replies View Relatedhi,
i am having trouble with a criteria expression that seems to have an issue when it runs into null data in my table.
the query column is as below ...
DateSerial(Year([SomeDate]),Month([SomeDate]),1)
and the criteria for this column is ....
DateSerial(Year(Date()),Month(Date()),1)
So basically I am looking for those fields that match the first date of this current month.
for some reason when there are null values in the table this thing chucks back data type mismatch error but when i take the criteria away its all good
any ideas why this is happening?
In my Accounts table I have a field called Status. This field is populated by single letters. A=Active, P=Paid and so on. I have a status (R) that is occasionally used. It won't show up in my crosstab queries since we currently do not have an account that is in R status. How can I get my crosstab to show the R status as having 0?
View 3 Replies View RelatedI've been struggling with a problem and I hope one of you can please help.
I created a crosstab query that displays group names on the vertical axis and dates on the horizontal axis. I use a Count for the values. I use a pop-up dialog to get parameters for the dates (between... and), which are organized as Quarters. The query works fine and I can insert it into a report, which also works fine... with one problem. The dates only work when the date parameters request a year (4 quarters), and only work when each quarter has at least one entry. (Only work = I get an error message when one or both of these conditions are violated.)
Sometimes, I want to look at less than a full year, but when I use parameters for three or fewer quarters, I get an error. Same thing if I request a quarter that doesn't have any data. I assume the solution is to convert Nulls to Zeros and have wrestled with both Nz function and IIf, but have not been able to convert the values. I get the correct values in the quary's dataset if they are numbers, and blanks if no data, but no zeros anywhere. I also don't know how to make my report flexible or dynamic, so I can limit the number of quarters if I only want to look at a specific quarter or quarters (less than four).
Any ideas? Thank you so much for your time, and, Happy Holidays!

So, I have two tables that, cut down, look like this:
Table1:
Code budget
100 5
110 7
120 3
150 6
Table2:
Code actual
100 4
110 9
130 2
150 1
I have another table that is all the codes plus a description.
I thought I was being clever because I realised that there are items in Table1 that do not appear in Table2 and vice versa. I need a query that is, in effect, Table1 minus Table2.
I linked all three tables via “code”, created my query with the minus calculations and thought it had worked.
One problem. Where there is a “code” in one table but not in the other, the query puts a blank or “null” into that field. Then the minus calculation gives, say:
null - 2 = null
I’m used to Excel where:
blank - 2 = -2
Is there any way to get round this please? This must be a common problem, no?
Thank you.
is there any way to make a cross tab query default to zero instead of nulls for unpopulated cells
i know i can Nz all the resultant fields, but it seems like treating the symptoms and not the cause...
:confused:
So, I've been doing doing reading on Append Queries and Nulls. I have the following SQL statement
INSERT INTO tblTestResults ( EnrollmentID, TestType, Result, CompletedDate, BoldFace )
SELECT tblEnrollment.EnrollmentID, tblTests.TestsID, [Forms]![frmHome]![subfrmTesting]![txtResult] AS Result, [Forms]![frmHome]![subfrmTesting]![txtCompletedDate] AS CompletedDate, tblOptionsBF.OptionsBFID
FROM tblEnrollment, tblOptionsBF, tblTests
WHERE (((tblEnrollment.EnrollmentID)=[Forms]![frmHome]![EnrollmentID]) AND ((tblTests.TestsID)=[Forms]![frmHome]![subfrmTesting]![cboSelectTest]) AND ((tblOptionsBF.OptionsBFID)=IIf(IsNull([Forms]![frmHome]![subfrmTesting]![cboSelectBF]),0,[Forms]![frmHome]![subfrmTesting]![cboSelectBF])));
and I can't for the life of me figure out.
IIf(IsNull([Forms]![frmHome]![subfrmTesting]![cboSelectBF]),"",[Forms]![frmHome]![subfrmTesting]![cboSelectBF
Basically what I'm trying to say is that if the cboSelectBf is Null, then leave it null for the the append query or at least leave it blank. If it isn't, use the value that cboSelectBF has according to the combo box selection.
Any help would be greatly appreciated.
Will someone look at my option group in my form (frmcustomer) and help me figure out why the option group selections for existing records nulls out (visually you cannot see which button had been previously selected).
The option group is working fine in that it is adding the appropriate selection to the record, but when you open the form up in edit mode the selection has been grayed out.
I have below table in SQL Server which i have linked to MS Access 2010.
Create table test
(
col1 int not null
col2 int not null
)
Insert into Test values (1,2)
Insert into Test values (1,'')
Now when i link the table to access database and open up the table i dont have any issues with that. I tried to copy the test table data from access table and paste it to another access table which is linked to sql server with same schema structure thats when it says "You tried to assign the NULL value to a variable that is not a variant data type"..Its treating the blanks as NULLS when copy/paste the records from one table in access to another.
In the following simplified query, in some months(MonthOf) there were no warranties so I have a null field for AcceptedWarranties:
SELECT qryWarranty.MonthOf, qryWarranty.AcceptedWarranties
FROM qryWarranty;
In order to make my Warranty Trends graph work I need 0s. Other postings show the following statement should get the results I need:
SELECT ISNULL(AcceptedWarranties, 0 ) FROM qryWarranty
But no matter how I try to work this into the original code, the compiler finds reason to reject it.
I'm using Access 2010 and I'm a novice with databases.I have a table that contains water flow readings taken 4 times a day from multiple wells. I am trying to create a select query that will generate the daily average of the 4 flow readings.
HoleID.....Date....Flow1....Flow2....Flow3....Flow 4....Average
1111.....9-8-14.......0.........null.........7..........4......
1111.....9-9-14.......0.........null.........9..........3......
2222.....9-8-14.......0.........null.........10........7......
Also, my table also has several 0 values and NULLS meaning the well was turned off - I want to exclude the zeros and nulls when I average. How to average these numbers? Do I need to restructure my table?
I have a table of around 6000 records comprising 4 fields (A,B,C,D).
- Each field can contain numbers or Nulls.
- Each record can comprise all numbers, a mixture of numbers or Nulls, or all Nulls.
I'd like to build a query that excludes all records that contain any number from a small list of numbers.
This sounds very simple but I am having problems when trying to include records that have Null's in my query output.
For test purposes I tried to exclude all records that contain the numbers 1 or 9 (these numbers can be present in any field).
This works perfectly, in isolation, on Field A (i.e. 1 or 9 but not Null are excluded from field A):
Code:
WHERE Table.A Not In (1,9) OR Table1.A Is Null;
When I try to copy the above, referencing fields B-D, I run into problems - no matter how I try to alter the Boolean operators.
I have a text field like, 11242010, and I need to be able to convert it into 3 int fields, day, month, year. I am trying to do this in a query and have create the following three;
DateD: IIf([DATE] Is Not Null,(CInt(Left(Right([DATE],6),2))))
DateM: IIf([DATE] Is Not Null,(CInt(Left([DATE],2))))
DateY: IIf([DATE] Is Not Null,(CInt(Right([DATE],4))))
Time: IIf([TIME] Is Not Null,[TIME])
When I have a value of Null, i keep getting #Error, I think when it's null.
I need to run a query counting how many policies a client cancelled. But I need the query to include zeros. Is this possible?
Here's my SQL Statement currently.
SELECT DISTINCTROW Pqry_CancelledPolicy01.Number, Pqry_CancelledPolicy01.Name, Pqry_CancelledPolicy01.POLICY_STATUS, Count(Pqry_CancelledPolicy01.Number) AS CountOfNumber
FROM Pqry_CancelledPolicy01
GROUP BY Pqry_CancelledPolicy01.Number, Pqry_CancelledPolicy01.Name, Pqry_CancelledPolicy01.POLICY_STATUS
ORDER BY Pqry_CancelledPolicy01.Number;
Thank you in advance for the help.
I've got a database that tracks name/address/phone, etc for a large group of people. I've recently added the ability to include a person's photo on the forms and reports. I've done that by saving the photos with the naming convention of [firstname]_[lastname].jpg and then using VBA, the database checks to see if there is a file with the corresponding name of the record and displays the picture if so.
It works very well, but I can see where I would have some problems in the future. For example, if someone gets married and changes their name, the corresponding photo must also be renamed to display properly. And if there are any misspellings, that becomes a problem. Also, if James decides he wants to go by Jim, the photo would not be displayed, either.
I'm wondering if anyone has any other ideas on how I might accomplish my goal. I know I could name the photo based on the record ID, but that's not a good option, since I'll be handling the photos, while someone else will be inputting the contact details. So I won't know the recordID easily.
Is there some way to have another field in each record that points to the corresponding photo? Then if James goes by Jim, his first name can be changed, but the corresponding picture name could remain the same.
Is there some great idea that I'm missing that would make this process much simpler and scalable? Or do I just have to deal with the maintenance issues?
Thanks.
