Hi. This might sound stupid but it is a real issue for us.
In our datafile some fields' values were updated to " " . A government entity wants the value to be blank, instead.
How do I change this?:confused:
Likewise, there are some instances where the reverse is true.
How do I change those?

I'm working on a db logging replies to a questionnaire. Judging by the responses I am receiving it appears that some sections are not completed at all. I need to be able to include these blank responses when it comes to analysis.
My design splits the questionnaire into sections, each section has a data entry form with its own underlying table. Each table has a primary key (autonumber field) which relates to each organisation that has replied.
If an organisation has failed to complete a section, I still need to create a new record in that section(table), triggering the autonumber field, hence referring back to the organisation.
I know I haven't explained this very well, but if anyone can make sense of what I'm saying and can give me any suggestions on how to make this happen, I would be most grateful.
In anticipation of your replies

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 have a form with a subform. The subform is used to report a sales total, for today and for the month. When there are no sales today (a null result in one of the fields) the entire subform goes blank.
How can I make it report a zero in the field instead of blanking the entire subform?
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 am attempting to use VBA code to make the label in my report hidden if the text box is blank. I am very new to coding, and am not sure how I would express this in code. I have been looking at a few examples of how to get this done, but it doesn't seem to work. Where to insert the code. Attached is the image of the properties for my label and text box that I want hidden if text field is blank. I al just lost trying to figure this out.
View 7 Replies View RelatedI am trying to show a certain subform based on whether or not a field is blank or null. This database is not owned by me--it's what we use to run queries and reports on the data on a centralized server for the library. It's not even in the same city--so changing the tables is not an option for me.
So, I have a subform (subform1) that is linked to the main form based on 2 fields (BibID and Item_Enum). The trouble is that the second field (Item_Enum) is sometimes blank, so the subform will not display. So I created another subform (subform2), which is a duplicate of the first one, but this time only linked on the first field (BibID). So, if that second field (Item_Enum) is blank, I want subform2 to display and subform1 to be hidden. If the second field (Item_Enum) is not blank, I want subform1 to display, and subform2 to be hidden.
I've tried putting the VBA code on different events for the form, but I can't get it to work consistently.
There are two problems, one of which I think I have fixed--but I would prefer a better solution. The VBA code doesn't run unless the form is newly loaded. I've tried placing the VBA code on different form events, but nothing works. I want the code to activate whenever a new record is displayed. The work around is that the form IS newly loaded every time the user scans a barcode for a new book. That works now, but if I need to change the way the user looks up new records, this might not work anymore.
The second problem is that the VBA code doesn't display subform1 when Item_Enum is blank. It doesn't display subform2 either, but that's the desired result.
Private Sub Form_Load()
If Me.ITEM_ENUM = "*" Then
Me.subform2.Visible = False
Me.subform1.Visible = True
Else
Me.subform2.Visible = True
Me.subform1.Visible = False
End If
End Sub
I've tried changing the condition to Me.Item_Enum = null, and changing the false/true results accordingly, but that didn't work either. In that case, only subform2 is visible, whether it should be or not.
I am in the process of building Append Queries for new records, and I know I can do an Update Query to enter specific information. However, how can I update multiple records from a (externally sourced) linked table to fill in blanks of an existing table? I have created a query to identify records with 1 or more matching criteria which contain the blank fields. I now want to update those blank fields. The data in each blank field is different for each record (same type, just different data).
View 1 Replies View RelatedThe unbound Parent form has a listbox (SQL Server) , the selection updates the SubForm with a primary key ID. The Subform is a ReadOnly view from an Oracle Linked table. It populates with a Select * From Oracleview where ID = listboxID The code is at the link shown below update: The subform uses textboxes linked to the read-only record.
The main form can populate, no problem. However the SubForm data source is either populated OR is Null.
If it is Null, the subform stays blank. Two Objectives:
1. Set a boolean variable flag in the parent (main form) that subform record exist or that it is null. e.g. Parent obtain recordset count property from Sub form
2. Display the subform with blanks.

I have a query which returns, among other things, a number of boolean fields. In some cases, there will be a genuine True or False value in each of these fields; in others, it can and should be Null (e.g. as a result of a 'failed' LEFT JOIN of some description, where there is no associated record in the joined table which fulfills the criteria)
So something like this :
Code:
SELECT [tblTable2].[fldBooleanField]....
FROM [tblTable1]
LEFT JOIN [tblTable2]
ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, I will be writing the result of the query to a text file and here's the problem. I want to show a numeric value for a genuine True / False (i.e. -1 and 0 respectively using the standard boolean conversions in Access) and a blank for any Null values.
So I tried this :
Code:
SELECT CInt([tblTable2].[fldBooleanField]) AS fldBooleanField....
FROM [tblTable1]
LEFT JOIN [tblTable2]
ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, currently when I look at the exported recordset in Notepad, I am getting 0's for both False and Null values (and -1 for True)
How I can adapt my query to keep Nulls...null? And convert the genuinely present boolean values to integer form?
Only thing I can think of is to use (untested) :
Code:
IIf([tblTable2].[fldBooleanField] Is Null, Null, CInt([tblTable2].[fldBooleanField]))
But there's a number of boolean fields in there, all requiring the same treatment.
Hi everyone,
I have a a table called [Email Database] with many fields
I need to create a query that replaces all Null values with blanks or ""
I'm not that familiar with SQL so any help would be appreciated!
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...
OK, I have been searching around on the fourm for over an hour now...I give up. If this is some where else, I am sorry.
I have a database of maintenance data. There are several columns that are usually filled in, some records have some columns blank. They are formated text because they hold letters and numbers (see pic).
I am using a form to query the table...no problem. The form has text boxes the user filter down the data
The problem comes are with the results of the query. Any record that has a blank column is not retuned. I am using "Like" so that the user can enter in partial codes. I know "like" won't return "null" records.... Help!
Things I have tried:
1)IIF(form field is blank, return table field, else use like command to filter) - returns nothing!
2)Like "*" & [Forms]![Fleetwide_data_Request]![MAL_CD] & "*" returns all records without blanks (i.e. missing data)
what else can I do?
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
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].
'###################################
Dim intCounter As Integer
intCounter = 0

Hi guys,
I have been running the same database on numerous systems for 5 years and the user clicks on a button and using this code;
DoCmd.OpenForm "Employee", acNormal
Simple !, this always opened this form blank, without applying filters, ready to accept a new employees details.
But now this no longer works, for no apparent reason?
What happens is that it opens with the form fields filled with the first person in the Databases details instead of being blank.
The only thing that could have changed is that i converted the database to 2003?
Any ideas?
Thank you in advance
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.
When entering information into a blank form, I would like to be able to continue entering information to another additional blank form after my last entry. Is there a way to continue to a blank form after entering information into the previous blank form? I would just like to continue without having to close the entire form and then reopening another form.
View 7 Replies View RelatedI have a form that has combo boxes and text fields (as well as sub forms). There is also a button linked to some code that says'

DoCmd.OpenReport "Quote", acViewPreview, , "BookingID = " & Me.BookingID

this code is behind the update button which i press when ever i want to shift data to History table
so when the fields are empty the invalid use of null error arrise
any idea how to handle this null specially in date
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 was wondering if there is a way to have a default value in a table field which is dependant on whether there was data enterd in said field or not. For example. I do not want any blank fields on my table instead I want "N/A" in the fields that were not used. I have tried setting the "default value" of the fields to N/A and it does work. The only problem is that all of the fields are filled with N/A automatically and in order to enter data one has to delete or "overwrite" N/A. Is there a way that N/A will be entered ONLY if the field is skipped over and left blank.

Hi - I have what maybe a relatively easy problem to solve.
I have a list of locations each with a unique id. I also have another table with location details in it. There is a relationship setup between the two tables. However in the first table I have some locations that do not have a match in the second table. Therefore that field is left blank. When create a query to show information from the two tables, any records that have a blank location match field do not get shown in the output. Is there anyway to display records with blank fields?
Thanks

Hi,
I have created a switchboard for a very basic DB and the first button is "ADD A NEW ENTRY"
When I click on this a form comes up but it bears the data from the first record.
How can I edit it so that a blank form comes up ready to receive data?
Best regards

Hi all
I have a numeric field in a form which initially is set to 0. When the user clicks or tabs to this field, it is blanked out in the got focus event by setting the field to "". This works great. Now, if the user exits the field by clicking elsewhere or tabing out of it, without entering a value, I would like the 0 value to be inserted again. I have tried many things to make this work without any success. Is there someone who knows the right way to do this?
Thanks in advance
