Queries :: Returning A Blank Or Null Value

Jun 18, 2015

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.

Queries :: Query Returning Blank Columns

Jun 24, 2013

I've set up a simple query that returns 6 columns of data.This query then shows on a sub-form elsewhere in my DB.The problem is that the query always appears with a horizontal slider. Allowing the user to scroll across to see the other columns in the query...The problem here is that there ARE no other columns of data. They are just empty. I want to restrict the output of this query to ONLY show the 6 columns that i have specified.

I have tried deleting the columns in Query Designer, then save the Query. But every time i re-open it half a dozen or so blank columns are stuck on the end.

Queries :: Search Not Returning Results With A Blank Entry

Oct 25, 2013

I have a switchboard which runs a google style search query to find people based on their first name, surname, date of birth or NI number on clicking the search button. It uses the following criteria in the query Like "*" & [Forms]![SearchF]![Firstname] & "*" for each of the above fields.

This works perfectly until someone inputs a record that doesn't have anything in one of the fields. ie, full name and DoB, but no NI number. When a record is entered in this way, the table stores the record but the search query cannot find it.

Queries :: Count And Sort Criteria - Returning On Blank Values

Nov 18, 2013

I have a list of employees and sort criteria. for example

empID....Criteria
1234......T
1234......F
1234......T
1234......F
1235......F
1236......T
1236......F
1236......F
1236......F
1236......T
1236......T
1237......F

The output I am looking for is a count of the number of times T appears by an employee, BUT is there is no record it would return 0

E.G.
empID......Count
1234...........2
1235...........0
1236...........3
1237...........0

I can get it to return:
empID......Count
1234...........2
1236...........3

using Count and the criteria Where Criteria="T" but not returning zeros.

Queries :: Field Criteria - Cannot Get Blank (Not Null) Records

May 15, 2013

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?

Queries :: Convert Boolean Fields To Integers / Blank For Null Values

May 22, 2015

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.

Query With Is Null Returning Not Null Records

Apr 18, 2006

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.

Blank Field Returning Error

Dec 8, 2011

I have some code that is below!

Code:
Public Function DegreeChecker(AGShrs As Integer, ASBAhrs As Integer, ASCJhrs As Integer, AAhrs As Integer) As String
Dim Degree As String
If ((AGShrs = 0) And (ASBAhrs = 0)) Then
Degree = "ASBA"
ElseIf ((AGShrs = 0) And (ASCJhrs = 0)) Then
Degree = "ASCJ"

[code]...

The problem is, the information that is populating the query which is running this code may not be there. As in some of the fields, AA, AGS, ASBA, and ASCJ might be left blank. Unless these four fields are populated by something, it returns #Error instead of the specified number.Is there a way to say, If variable is blank, ignore and continue on to check if the next thing is 0, or if none are 0, state Potential.The information in this query is to be exported out to excel to be used as a Mail Merge file.

Returning Null Records?

Jan 14, 2008

Hello everyone.

I have just joined the forum and spent the last day or so looking around for an answer that I wasn't able to find.

I have been asked by my employer to capture details of who has signed our confidentiality policy. I have made a very simple database which only has three tables, EMPLOYEE, POLICY and VERSION.

EMPLOYEE has three fields, NAME, NUMBER and BRANCH. POLICY has three fields, NUMBER, DATE and VERSION. VERSION has two fields, VERSION NUMBER and DATE. I won't worry about the VERSION table any further in this post as it doesn't figure in the problem query.

Primary key for EMPLOYEE is NUMBER. Compound key for POLICY is NUMBER and DATE (ie. the employee can sign the policy more than once and we want to record when this was, and whether the policy version changed).

I have an Access "type 3" join defined in table relationships from EMPLOYEE.NUMBER to POLICY.NUMBER.

I am trying to write a query that returns the employees that haven't signed the policy. I have no problem returning the employees that have (ie. employees whose numbers match the numbers in the POLICY.NUMBER field), but it is the EMPLOYEE.NUMBER entries that are not present in POLICY.NUMBER that are causing me grief.

I have tried using the expression builder in the query builder window (it gave me <>[tblPolicy]![Number]) which doesn't return any records (I have over 490 in the database and should be getting back at least 50 or so).

Sorry if this question is too basic.

Can anyone offer me any advice here?

Thanks in anticipation.

John

Query Returning #error When It Should Be Null

Jun 24, 2005

I have a left-join query where I know that some of the values in the left-hand table have no corresponding values in the right-hand table...that's why I used a left-join: I want all the values in the left-hand table to show up. I would expect that records without corresponding values in the right-hand table would show up as nulls (I swear I have dozens of other queries that work this way) but in this one, they show up as "#error" instead.

This is a problem because I want to do some calculations on this field. Normally I would use the nz function to change the nulls to zeros.

So,
1. Any idea why this is happening?
2. Is there a way to change the #error values to zeroes, similar to using the nz function?

HEre's the SQL:
SELECT FeederInventorySummary.machine, FeederInventorySummary.Size, FeederInventorySummary.Leaf, FeederInventorySummary.Type, FeederInventorySummary.CountOfFeederID,FeederNeeds Summary_7.FeederQty FROM FeederInventorySummary LEFT JOIN FeederNeedsSummary_7 ON (FeederInventorySummary.Type = FeederNeedsSummary_7.Type) AND (FeederInventorySummary.Leaf = FeederNeedsSummary_7.Leaf) AND
(FeederInventorySummary.Size = FeederNeedsSummary_7.FeederSize) AND (FeederInventorySummary.machine = FeederNeedsSummary_7.ActualMachine);

For every record without a corresponding record in FeederInventorySummary_7, the FeederQty field shows up

as #error.

QBF Problem Returning Null Entries

Mar 3, 2007

Hi, first of all I have to say I'm quite a noob at Access, so I apologise if my question seems stupid. :p I Googled for quite a bit looking for a solution but couldn't really get anything to work (maybe because I wasn't doing some of the possible solutions correctly?).

Anyway, I have a database with two tables, and I'm trying to make a QBF to search for data from these two tables. Quite a few of these entries have null values.


SELECT [M-Table].Firstc, [M-Table].Secondc, [S-Table].Thirdc
FROM [M-Table] LEFT JOIN [S-Table] ON [M-Table].Firstc = [S-Table].Firstc

WHERE

((([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([Forms]![interface]![TxtFirstc]) Is Null)
AND (([Forms]![interface]![TxtThirdc]) Is Null))

OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([Forms]![interface]![TxtThirdc]) Is Null)
AND (([Forms]![interface]![TxtSecondc]) Is Null))

OR ((([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*")
AND (([Forms]![interface]![TxtFirstc]) Is Null)
AND (([Forms]![interface]![TxtSecondc]) Is Null))

OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([Forms]![interface]![TxtThirdc]) Is Null))

OR ((([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*")
AND (([Forms]![interface]![TxtFirstc]) Is Null))

OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*"))

OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*")
AND (([Forms]![interface]![TxtSecondc]) Is Null));


This really long and tedious code was the only way I could get it to work such that in my query form, if I leave any one of the fields blank the search will still pull all the related results out, regardless of whether there are nulls in the values themselves, e.g. if I search for anything with "ab" in Secondc, it will give me all the data with "ab" in Secondc, even if there are null values for those entries in Firstc and Thirdc. Similarly for searches with the other fields.

I tried using IIF and Nz, first using IIF under Criteria, then I read somewhere that they should be used under Field rather than Criteria, but I couldn't really get it to work. Either the QBF wouldn't return any results, or it would return only those entries without null values, so if I searched for "ab" in Secondc, I wouldn't get the entries that had "ab" in Secondc but null values in either Firstc or Thirdc.

The problem with my solution is that I wouldn't be able to get it to work in another database with like 10 fields. The number of combinations would be a killer...

Is there any workaround? Many thanks! :)

Query Not Returning Null Values

Oct 10, 2011

2007 version - my child query is not returning null values. I have 2 fields, both pulled from a parent query. One is "DaysSinceRecd", the other is "AmountPaying". The parent query returns multiple results, which is fine. For example, the parent query might have 10 different records for "0" "DaysSinceRecd", with different "AmountPaying" for each of those records.

In the child query, I am trying to condense that down, so that I only have one "AmountPaying" for each "DaysSinceRecd". It's working fabulously, except that there are records in the parent query that have a value for "AmountPaying" but a null value for "DaysSinceRecd". The null value for "DaysSinceRecd" cannot be changed to another value, it needs to stay null. My child query is not returning the null records. I tried adding to the criteria: IsNull Or IsNotNull, >=0 or <=0. That's not working.

Modules & VBA :: Search Form Not Returning Records With Blank Fields

Nov 14, 2013

I'm creating a search form to filter out data based on certain inputs. My VBA code looks like:

Code:
Private Sub Command18_Click()
On Error GoTo errorcatch
Me.Filter = "([Experiments.Log] Like ""*" & Me.Text21 & "*"") AND ([Expdate] Like ""*" & Me.Text22 & "*"") AND ([BaseSolution] Like ""*" & Me.Text24 & "*"") AND([AddCom] Like ""*" & Me.Text25 & "*"") AND ([Test] Like ""*" & Me.Text26 & "*"") AND ([Plan] Like ""*" & Me.Text23 & "*"")"

Me.FilterOn = True
Exit Sub
errorcatch:
MsgBox "Error #: " & Err.Number & vbCrLf & vbCrLf & Err.Description
End Sub

However, the output does not include records where other fields are blank. I have read that I may need to use Is Null but am not sure how to.

Forms :: ComboBox Doesn't Display Some Values - Returning Blank

Feb 10, 2014

In a form used to record a sale for a company we have a dropdown box with the contact names for that company and when one is selected it populates other boxes like phone number etc however the combobox brings up all possible contacts but when some of them are selected all the boxes return blank, including the combobox, whereas most of the contacts work fine.

The SQL used for the combobox is as follows..

Code:
SELECT tbl_Contacts.ContactTelephone, tbl_Contacts.ContactMobile, tbl_Contacts.ContactEmail, tbl_Contacts.ID_Contact, tbl_Contacts.ID_Company, tbl_Contacts.Salutation & " " & tbl_Contacts.ContactForename & " " & tbl_Contacts.ContactSurname AS MainContact
FROM tbl_Contacts
WHERE (((tbl_Contacts.ID_Company)=[tbl_CompanyBookings].[ID_Company]))
ORDER BY tbl_Contacts.ContactForename;

Why some contacts work and some don't ??

ComboBox Querying Table, Returning Null ?

Aug 8, 2005

Is anyone else experiencing similar problem ?

Basically here's what happen:

1. User need to look up item name, while in a subform. He pressed F5
2. A form showed up, with a ComboBox (which got its values from a query)
3. User chose an item name in the ComboBox, and then pressed the Close button
4. The item name got copied into the subform.

Problem is, for some items/records, step 4 doesn't happen :eek:
When I investigated, turned out that for some records, the ComboBox returned null (instead of the selected record)

This is on a 5800+ records table, on Access 2000.

Here's the code :

[Forms]![005_cashier].[subform_0051_enter_sold_items]!selling_price = Me!item_name.Column(2)
[Forms]![005_cashier].[subform_0051_enter_sold_items]!quantity = 1

The second line always works (always got copied to the subform properly), while the first one only works with certain items/records.

I've examined the offending records, but couldn't imagine how they'd be able to make Access to behave like that.

Any ideas ?


Thanks,
Harry

Returning All Records If Dependent Field Is Null

May 14, 2007

Hi. I'm unable to work out how to set up a query which will filter records according to what is returned by one control, but will also list all records if the value of the control is null.

Situation: I have a CONSULTATION table linked many to many via a CONSULTATIONLIST relation table to an ADVISOR table. (An Advisor may be present in any number of Consultations, and a Consultation may include any number of Advisors.)

I have a CONSULTATIONMANAGE form enabling the user to select an Advisor from the table ADVISOR via a combo box called SELECTADVISOR which returns Advisor ID (adID).

My CONSULTATION form, displaying the list of consultation records, currently has, as record source, the following query:

SELECT Consultation.*, Advisor.adID
FROM Consultation INNER JOIN (Advisor INNER JOIN ConAdList ON Advisor.adID = ConAdList.adID) ON Consultation.conID = ConAdList.conID
WHERE (((Advisor.adID)=[Forms]![ConsultationManage]![selectadvisor]));

This query correctly lists only those Consultations in which the selected Advisor was present.

Problem: What I also need to do is show ALL Consultation records if the user does not select an Advisor from the combo box.

Any help would be much appreciated.

Mat.

Query Not Returning Records When Criteria Set To Is Not Null Or Date Range

Feb 20, 2013

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?

Updating To A 'null' Or 'blank'

Mar 15, 2007

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?

Records With Null/blank Fields Only!??

Jun 8, 2005

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

Queries :: Pulling Records Based On Blank / Non-blank Criteria

Jul 18, 2013

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...

How can I make it report a zero in the field instead of blanking the entire subform?

Showing Subform Based On Whether Or Not A Field Is Blank Or Null

Sep 15, 2015

I 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.

Modules & VBA :: Unbound Subform Has No (null) Records - Form Stays Blank

Aug 4, 2015

The 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.
