How To Filter On A Column That Sometimes Is Null?
Aug 14, 2006
Hi!
I want to be able to filter a form based on a dropdown box, where one of the items can be null. (The field is of type short date).
the dropdown box is named "Fltr1".
The form is based on a query, and i have tried to express the filter in the query like this (sql syntax):
([Tablename].[Columnname]) Like "*" & [Forms]![frmMyForm]![Fltr1])
But this way, the records with this column being null are omitted...
I very much appreciate any help that leads me in the right direction ;)
thanks

I do not understand what is happening here. I have foll0wing line in a calculated query field:
m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010
this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.
But if I do this:
m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example
then the entire column is set to Null

Okay so I have a column called 'totalincome' on TblCashflow. There are 60 records of TotalIncome (represents 5 years or 60 months) per asset that I have on another table, TblLoanGeneral.
What I need to return is the LAST value from totalincome that is not null. For example, we may only have entries in the 60 records that go to row #35, or 50 or whatever. When I use the Last criteria it gives me the 60th record (in example would give me a 0), and when I use the Max criteria, it gives me the largest income value regardless of location(would be 50,000 in example). What I need is really where the "last" income amt is >1 (20) however, when you set last, it only considers row 60.In the example below I would want 20 to be returned.

Can't figure out the syntax for specifying a null value for a text or combo box when filtering a table via a form. "Is Null" seems to work for query criteria but doesn't work for form controls. If one right-clicks on a form control displaying a null value, one of the choices is "Equals Blank" which if selected works fine but what does one use for the text filter if the record for the control in question does is not displaying a null value?

Hello Everyone,Been a while since I needed to post on this forum, but I found something rather disturbing today; either that or I have missed something obvious. I have a large query of financial data, and I filter out certain codes which I don't want to include. The filter is;<>"BL01" And <>"SS01"Which works as it should, filtering out all BL01 and SS01. However, it also filters out any NULL values, which is something I would not expect it to do. When I enter NULL as a filter, I get the records I expect. What am I doing wrong here? I am using Access 2003 SP3 on Windows XP Service Pack 2

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 two combo boxes ref 1 and ref 2
Both have the same source list but I would like the ref 1 list to exclude ref 2 and the ref 2 list to exclude ref 1 but I am struggling when either value is Null gives me no list.
Ref 1 row source
SELECT [Reference Probes].Ref, IIf([Forms]![frmCalibration]![Ref 2]=Null,([Reference Probes].[Ref]) Is Not Null,[Reference Probes].[Ref]) AS Expr1 FROM [Reference Probes] WHERE (((IIf([Forms]![frmCalibration]![Ref 2]=Null,([Reference Probes].[Ref]) Is Not Null,[Reference Probes].[Ref]))<>[Forms]![frmCalibration]![Ref 2]));
Ref 2 row source
SELECT [Reference Probes].Ref FROM [Reference Probes] WHERE ((IIf([Forms]![frmCalibration]![Ref 1]=Null,([Reference Probes].Ref) Is Not Null,[Reference Probes].[Ref])<>[Forms]![frmCalibration]![Ref 1]));
Ref 1 after update has Me.Ref_2.Requery
Ref 2 after update has Me.Ref_1.Requery
As you can see I have tried two different ways but both don't work.

This is the function i'm using for summing a listbox column:
Function TonSum() As Variant
Dim I As Integer, J As Integer, ctl As Control
Set ctl = Me.lstDrivera2
J = ctl.ListCount - 1
[code]...
The problem i have is if one the records in the listbox doesn't have a value (is null) then Access gives me a 'Type Mismatch' error. How to treat the null value so it excludes it from the sum?

I have a main form with multiple combo boxes that filter a subform datasheet. In my main form combo box [PR_Filter] I added a selection titled "<Blanks>". When I select "<Blanks>", I want it to filter my subform field [PR] for NULL values. If I select anything else I want it to filter on that selection. I cannot get the NULL filter to work.
Here is the code that I have (Red is the field I need the NULL values):
Private Function PurchaseFilter()
Dim strFilter As String
Dim bFilter As Boolean
bFilter = False
strFilter = ""

I've been trying to populate a field in a form with information, but only if the field is blank.
What I am trying to do is this.
I have a continuous form displaying all of our principals, however when our principals are on leave I want to populate the field with the "acting principal". I have set it up so the field grabs the acting principal first but it is blank for several schools. For these schools where there there is no "acting principal" I want it to grab the substantive principal automatically and populate the field.
I have tried Is Null, Is Not Null, NZ, IF, Where and Then statements but to no avail.

how to return all values in a query when a form critieria is left blank. I have made some progress, the combo box criteria queries were fairly simple, but i'm getting stuck with my date criteria. My query doesn't return null values when I want it to.
I want it to return all records (including null values) if the form OpenFrom and OpenTo dates are blank, and just the values between the selected dates (excluding null values) if the form is completed.
Code:
SELECT qryReportSelector2_Authority.*, qryReportSelector2_Authority.ApplicationDate AS ApplicationDateFilter
FROM qryReportSelector2_Authority
WHERE (((qryReportSelector2_Authority.ApplicationDate) Between Nz([Forms]![frmReportSelector]![OpenFromDate],DMin("[ApplicationDate]","[qryAllCases]")) And Nz([Forms]![frmReportSelector]![OpenToDate],DMax("[ApplicationDate]","[qryAllCases]"))));

I am currently having trouble filtering my subform by a different column than the bound column set in properties.
the comobobox shows the ID for the last email sent, with the combobox drop down showing the name and date of email when dropped down. I have tried 2 things and neither work...
1) Calling the filter on the combo-box column itself:
Code:
Dim myDate as string
myDate = [Forms]![BenSearchForm]![BenSearchSub]![LastEmail].[Column(5)]
DateFilt = " AND" & myDate & " BETWEEN " & "Nz([forms]![BenSearchForm].[Date3],#1/1/1900#) AND Nz([forms]![BenSearchForm].[Date4],#31/12/2100#)"
I have used similar code on another form, but I can't get the myDate variable to get to value of the 6th column in the dropdown (Date Of Email). an Easier way to look at this would be:
Code:
DateFilt = " AND [Forms]![BenSearchForm]![BenSearchSub]![LastEmail].[Column(5)]" & " BETWEEN " & "Nz([forms]![BenSearchForm].[Date3],#1/1/1900#) AND Nz([forms]![BenSearchForm].[Date4],#31/12/2100#)"
2) Inside the subform, I have set up a seperate field that reads the result of the dropdown box column(5) and shows it. For example the Email with ID 22 has a date of 4/8/15, so any record with last sent email being 22 has a record that says 4/8/15. I am trying to use this value to filter between, but am unable of passing the value to my filter.
The textbox is called "Email Date" and the Control source is "=[Forms]![BenSearchForm]![BenSearchSub]![LastEmail].[Column](5)"
It shows the correct data, but does not allow me to filter by this field, when the apply filter button is pressed it asks me for the parameter value of the LastEmail Field.
Code:
DateFilt = " AND" & " [EmailDate] BETWEEN " & "Nz([forms]![BenSearchForm].[Date3],#1/1/1900#) AND Nz([forms]![BenSearchForm].[Date4],#31/12/2100#)"
I use a number of set variables for my filters, so my filter ends up looking like
Code:
.Filter = IDFilt + EmailFilt+ DateFilt
where all but IDFilt begin with AND. I use this on a number of other forms so I am sure this is not the issue!

I would like to get minimal value from "Ski" column. Need to use recordset instead Dmin function because this value will be changed many times. I work with dao.recordset but I never used recordset filter so I need to do something like this:
Code:
strSQL = "select tblGoraZleceniaNowaWyceny.id_gora_zlecenia, tblGoraZleceniaNowaWyceny.naklad_pracy, tblGoraZleceniaNowaWyceny.nazwa, tblGoraZleceniaNowaWyceny.Ski, tblMontazSzczegoly.iloscuzytkow from tblGoraZleceniaNowaWyceny inner join tblMontazSzczegoly on tblGoraZleceniaNowaWyceny.id_gora_zlecenia = tblMontazSzczegoly.nazwa where tblGoraZleceniaNowaWyceny.id_wycena_pre=" & Forms!frmWycenyObszarRoboczy!ID_wycena_pre & " order by error desc"
Wor = 5
Get the minimum value from strSQL (Ski column)
update this value = Ski+1
wor = wor-1
and loop all procedure until Wor = 0
So the problem is how to requery strSQL to show NEW minimum value at the beginning query - rst.requery doesn't work.

I'm not familiar with listbox yet and i want to filter my form using it.
I have two separate listboxes which display "category" & "type" data from the same table.
Here is the situation i wanted for my listbox.
1. Select one data from "category" listbox.
2. Then it will automatically filter data from "type" listbox or it will list all related "type" data corresponding to "category" data.
3. Then select one data from "type" listbox and it will filter all related data on the form/sub-form.
Is it possible to do that way? Can i do it on multicolumn listbox instead of using 2 listbox?

I have a column that has a bunch of keywords they are separated by comma... so for each row of that column it will have a few different keywords example: lake superior, river, mountain, lake wollongong
I know its a bit of a nono with databases to have columns with comma separated text.. well so i read somewhere anyway but the document i have been handed to work has hundreds of rows in this column with up to 14 keyword entries.
I have a form that searches through Item's names based on 2 keyword boxes.
Here's the criteria in my query:
Is Null Or Like "*" & [Forms]![frmItemView]![SearchPhrase1] & "*" And Like "*" & [Forms]![frmItemView]![SearchPhrase2] & "*"
This will show all records when both keywords are blank, and filter records using the 2 keywords otherwise.
I have a form with two text boxes and have set the correct values as outlined in Evans post. I then have the query set to run via a button. I run it but it will only give back records for the entry i have put in the 1st text box. This would work well for me otherwise... mine is like this:
Is NULL or Like "*" & [Forms]![Searchtable]![Key1] & "*" And Like "*" & [Forms]![Searchtable]![Key2] & "*"
Searchtable being my search form
key1 being my first text box entry
key2 being my second text box entry

I have a user form in Excel that sends data to a table in Access 97.
(Due to restrictions on system).
I will need to pull reports off this table to send via email to Lotus Notes 8.5
Is there a way I can filter the report depending on the data entered in a column?
aka If a cell in a column has "Cheese" I can run a report showing just the "Cheese" results?

I have a form that shows multiple rows of linked/child records.The form in question is the "frmFilterNumberTypeView" form. When a particular filter is used (installed on an automobile), I would like to be able to click on the corresponding "Installed 1" button left of the filter number, so that by code, I can reduce the Qty on Hand by One, and insert the corresponding filter ID to the History table, along with the date/time the filter was used.
how to reduce the Qty on Hand, nor how to do the updates to the History table, I'll figure that out myself over the next week or two (hopefully it won't take that long). What I'm trying to figure out here is how I can associate the red "Installed 1" button with the filter to the right of whichever button I press.
how to sort the filter column on this same form. I'm fairly certain that this would be very easy to do if the subform in question was populated by means of a corresponding query, but I'm afraid that if I go that route that I'll spend another 20+ hours trying to figure out how to get the proper filter records to match the filter manufacturer, not to mention having to next figure out how to link the table so that if I modify any particular filter record, that I'll be able to have the associated table update accordingly.
Is it possible to sort the filter column without the subform record source being a query?

I have a listbox on a form displaying records which can be filtered via a number of comboboxes.
These comboboxes allow the user to select "<ALL>" or a specific value from the list. It all works perfectly.
However, I would like to be able to select a filter value of "Null" on one of the comboboxes which would display those records without a value in the relevant field.
How can I do this?
The following (simplified) code is what I'm using:
SQL for the results listbox:
SELECT qryClientSearch.ID, qryClientSearch.Name, qryClientSearch.AccountManager, qryClientSearch.AccountMgr
FROM qryClientSearch
WHERE
(
((qryClientSearch.ID) Like fCboSearch([Forms]![frmClientSearch]![cboSearchName]))
AND
((qryClientSearch.AccountManager) Like fCboSearch([Forms]![frmClientSearch]![cboSearchAccountMgr]) Or (qryClientSearch.AccountManager) Is Null)
)
ORDER BY qryClientSearch.Name;
SQL code for the combobox filter:
SELECT qryStaff_All.ID, qryStaff_All.Nickname FROM qryStaff_All
UNION
(SELECT "*" AS ID,"<ALL>" AS Nickname FROM qryStaff_All)
ORDER BY qryStaff_All.Nickname;
VB Code in Combobox Search Function:
Public Function fCboSearch(vCboSearch As Variant)
If IsNull(vCboSearch) Or vCboSearch = "" Then
fCboSearch = "*"
Else
fCboSearch = vCboSearch
End If
End Function
For those that have noticed I have a "Or is null" criteria on the AccountManager field in the result set. I want to take this out and allow the value "Null" to be selected on specifically.
Thanks.
