I am having problems with setting up a set of combo boxes.
What I am trying to do is if combo Productline is empty then in combo PartNumber would show all products but if combo Productline has a value selected then in the combo partnumber would only be able to select the partnumbers in that productline.
I think the title pretty much sums it up....
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
The query is refusing to return any results...
Any ideas?
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
It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code:
Private Sub cmdUpdateDates_Click()

'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time].

Hello all,
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Thanks.
I have a form with two controls: DateFrom & DateToI want to filter based on those criteria but when the criteria is ommitted (NULL) I want to display all.In case of other controls I have an SQL as follows:... WHERE (tblClassesOffered.Course = Forms!frmClassReport.class Or Forms!frmClassReport.class Is Null)But with the dates controls the best I could come up with is:...Between IIf(IsNull([Forms]![frmClassReport].[DateFrom]),#1/1/1900#,[Forms]![frmClassReport].[DateFrom]) And IIf(IsNull([Forms]![frmClassReport].[DateTo]),#1/1/3000#,[Forms]![frmClassReport].[DateTo]) Or Is NullHowever that solution is kind of ugly becasue instead of wild cards (I couldn't make them work) I'm using those made up dates and I also wish not to use the IIF if possible (like the first statement).
View 2 Replies View RelatedI learned the criteria on this forum
Forms!FormName!Control or Forms!FormName!Control Is Null
It enables me to leave the text box on a search form blank to return all records. This seems to work but has a very odd behaviour.
In design view, I typed the criteria for 3 fields and saved the query, but when I reopened it, the criteria added 3 NEW COLUMNS and spread over 8 ROWS (as in the image attached.)
The SQL was even unreadable:
SELECT Table1.ID, Table1.FldA, Table1.FldB, Table1.FldC
FROM Table1
WHERE (((Table1.FldA)=[Forms]![Form1]![txtA]) AND ((Table1.FldB)=[Forms]![Form1]![txtB]) AND ((Table1.FldC)=[Forms]![Form1]![txtC])) OR (((Table1.FldB)=[Forms]![Form1]![txtB]) AND ((Table1.FldC)=[Forms]![Form1]![txtC]) AND (([Forms]![Form1]![txtA]) Is Null)) OR (((Table1.FldA)=[Forms]![Form1]![txtA]) AND ((Table1.FldC)=[Forms]![Form1]![txtC]) AND (([Forms]![Form1]![txtB]) Is Null)) OR (((Table1.FldC)=[Forms]![Form1]![txtC]) AND (([Forms]![Form1]![txtA]) Is Null) AND (([Forms]![Form1]![txtB]) Is Null)) OR (((Table1.FldA)=[Forms]![Form1]![txtA]) AND ((Table1.FldB)=[Forms]![Form1]![txtB]) AND (([Forms]![Form1]![txtC]) Is Null)) OR (((Table1.FldB)=[Forms]![Form1]![txtB]) AND (([Forms]![Form1]![txtA]) Is Null) AND (([Forms]![Form1]![txtC]) Is Null)) OR (((Table1.FldA)=[Forms]![Form1]![txtA]) AND (([Forms]![Form1]![txtB]) Is Null) AND (([Forms]![Form1]![txtC]) Is Null)) OR ((([Forms]![Form1]![txtA]) Is Null) AND (([Forms]![Form1]![txtB]) Is Null) AND (([Forms]![Form1]![txtC]) Is Null));
I don't know how to add the criteria for the 4th field.
Can someone help?
Thanks

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?
View 2 Replies View RelatedI had an issue with writing LIKE statements in query criteria yesterday [URL]....
The answer they gave worked perfectly when I only used a single table in the query. But as soon as I did an INNER JOIN with two other tables, now I get parameter value prompts when I open frmSearch, and instead of seeing ALL my records when the controls are left null, I get only the first record in the table.
Here's the SQL of the query, can you point out what I messed up? NOTE that this SQL was 'written' by Access.. as I used the Query builder to set all the 'Like or Is Null' statements, then clicked SQL and sorta formatted the code so I can see what I'm looking at (instead of superthick wall-o-code):
Code:
SELECT tblPeople.name, tblPeople.num
FROM (tblPeople INNER JOIN tblAddresses ON tblPeople.name = tblAddresses.name)
INNER JOIN tblPets ON tblPeople.name = tblPets.name
[code]....
Basically, this is a searchable database of participants in a pet-adoption program, along with the participants' pets history and address history (hence the linked tables as opposed to additional columns in one single table for pets and addresses... there are more than one in some cases). The frmSearch allows a person to run quick searches based upon ANY item in the database, such as name, pets, addresses, pet age, pet type, county of residence, etc. I need to be able to pick ANY field on frmSearch and type a value, and have the qrySearch return records for ANY record's related column wherein any part of it matches what I typed.
The statements as written worked PERFECTLY right up until I added the INNER JOIN. Now I get a set of parameter value prompts for every field on frmSearch that's referenced in the SQL for EACH table I linked to tblPeople, and if I leave everything null and click Search, I want to see EVERY person, but I'm only seeing the very FIRST person in tblPeople.
I have field in my table, which is required (in access, or not allow null sql server), and have defaults of 0.
I have a form with a combo box bound (thru query) to this field - how do I let the user choose something from the list and then decide they actually didn't want to choose anything - and so clear the list.
Hear I get an error saying the field cannot accept null - how do I just force it to accept 0 - ie no choice??
Thanks
I have what I think is a simple query returning the names of students that have been dismissed since September 2012 using a "WithdrawnDate" field. The query pulls a lot of information from other related tables (about 6 different ones), and has two expressions.
When the criteria is set to either "Is Not Null" or a date range (which is all I need), it does not return the complete set of records based on the data that fits the criteria in the main table?
Could there be some sort of join preventing all records from being returned?
Hello!
Looks like a grate forum for access topics and thats exactly what I need now! I'm new to Access and are going grazy!!
I'm trying to add some functions to an excisting database that someone else has done.
The Form creates an report from an db containing a one per day status information from water and electrical meters. Filling in start and stop dates gives a nice report over all meters and their status.
Now I want to add a combo box so the user can select one meter or leaving it empty to get all meters. I can make it work when selecting one meter in the list, but leaving it empty shows none. Or selecting any don't help all of the meters shows up anyway.
I used the search engine on this forum and found similar problem, but couldn't figure it out. Tried many combinations of the IIF statement, but didn't help.
Please help me!!

Hello All,
Im using a combo box for the criteria for a saved query. Is there any way to show all the records if the combo box value is either 0 or null?
Thanks,
I have a form that using a combo box to select specific record, sometimes we need to see all records, i would like if the combo box if left empty to return all records. I typed this expression but it returns no records when combo box is empty.
IIf([Forms]![FrmReports]![LoanOfficer]="IsNull","*",[Forms]![FrmReports]![LoanOfficer])
If i use this expression i get the wrong results when a Loan Officer ID is enterd;
LIke([Forms]![FrmReports]![LoanOfficer] & *
Example of wrong results, if Loan officer Id is 1, then it returns loan officers 1,11, 111
Thanks in advance for any help

I can't seem to figure out how to test a combo box null value.I try:
Code:
If IsNull(Me.cboManufacturer) Then
MsgBox ("Please select category")
Else
DoCmd.OpenReport "rptItemCategory", acViewPreview
End If
This works if the combo box IS NOT NULL, but if null it gives me:
PHP Code:
Run-time error '3071': This expression is typed incorrectly, or it is too complex to be evaluated.
For example, a numeric expression may contain too many complicated elements.
Try simplifying the expression by assigning parts of the expression to variables.
I then tried:
Code:
If IsNull(Me.cboManufacturer.Column(0)) Then
MsgBox ("Please select category")
Else
DoCmd.OpenReport "rptItemCategory", acViewPreview
End If
This works if the combo box IS NULL but if i've made a selection, it still gives me the message box as if I've selected nothing....
We just upgraded to Office 2010 from 2003 and I am now getting 'invalid use of null' after choosing a valid combo box option. When I debug, the line that highlights has to do with a text box on the form rather than the combo box. Here's the code highlighting:
frmLines = Me.WorkLoadUnit
This is the code in it's entirety.

I have a combo box in a form which simply pulls a text field from a single table - approximately 100 values to choose from. On the After Update Event, there is a basic "If null this, else that" VBA which just hides a subform if the value is null. This works fine, except there are a handful of values (I've found at least 6) that when chosen, trigger the NULL portion of the code! All the values are very similar, so I don't know what the problem is - for example, the value "D-11" works, but neither "D-10" nor "D-12" does.
View 11 Replies View RelatedI have a form, form1. Inside there is a combo box, cbo1, that gets its values from table1.On form load, I want an expression that checks if table1 has any values to "send" to cbo1. If yes, meaning, if after form loads cbo1 is loaded with table1's values, I want cbo1 colored RED, if not, colored WHITE.

I want to pass the Combobox value of one form to a textbox on another using the where condition. Using the break in VBA, the value of the combobox (in this instance "two") shows as null. the control of the combobox is [cboSubCategory] and I want it's value to pass to another form "tblCategoriesSub" (aware of the incorrect reference, as used wizard quickly - but will change if I can get it to work) to the "SubCategory" field.
View 5 Replies View RelatedI am assigning a recordset using vbs code. The variable "CB_proj" is a combobox value. The problem comes when the combobox is null, the program errors out and even if I try to exit the routine with an if statement, it still compiles the line of code and errors out because the object doesn't exist. how I can get it to not compile that error if my combo box value is null?

I have a SQL Server 2005 backend table with a varchar(1) field which allows nulls. The field is populated from a combo box in Access 2012. The field can be set to 1,2 or 3 via the combo box or left blank in which case its value will be null. Sometimes I need to reset this field to null. How can I do this via a combo box? I know I could just set this to an empty string but this would mean re-writing a load of queries which a looking for a number or null.
Something like 1;"First";2;"Second";3;"Third";Null;"Blank"
On a form, I want to disable the save button, 'cmdSave' whilst the form's mandatory fields have been left blank.
I've put in a smart tag, called, 'Req' against each required field and have used the following code on the forms current event.
Code:
Private Sub Form_Current()
Dim ctl As Control
For Each ctl In Me.Controls
If ctl.ControlType = acTextBox Or ctl.ControlType = acComboBox Or ctl.ControlType = acListBox Then
[Code] ....
The save button is disabled, but it won't enable again after each field has data entered against it.
I also have this code in the AfterUpdate event in each required field:
Code:
Private Sub cboErrorID_AfterUpdate()
Call Form_Current
End Sub
I have created a data base over the last few months I just kept adding information in the fields that I created but now have a problem I have the sections in a drop down menus of which access will let me ad info but when I com to save I get this message
"Index or primary key cannot contain a null value"
Access will not let me save any added info in any field I have tried all the ways that I know to get round this problem to no avail it is most properly some think silly but I am desperate now as I have worked hard on this project.
