Showing Records With A Null Value On Form
Apr 26, 2006
Ok this null value thing is killing me. I have a parameter query that works great. I know if I use Is Null in the criteria field it will show me this. The problem is I made a search form which the users type the value in and it opens a form based on the parameter query, the parameter on the query is [Forms]![Search_frm]![txtClosed]. If they type a date in here it opens the form and shows the user all the closed records. The problem is they want to see all the records that have no value or Null. I've tried eveything to make this work. I'm ready to jump!! Just kidding. Is there a way to do this with out creating another query. Thanks a bunch!!!

Hey Gang,
Thanks for all your help on my previous problem but I now have another one that just seemed to start out of the blue. When I open my form the record selectors don't allow me to browse through all the previously entered records. This is a huge problem because if changes need to be made I can't call up the record to do so. I plan on adding a search funtion to the database soon but for now I need to be able to search through the records on my main form. Is there something I should look for or do you have any suggestions?
Any help would be greatly appreciated.
Cheers,
axsnub (access newbie)

I am building a search form in my DB. I have got this working by using a text search box on the main form which then links to a subform that shows the results. This works great, however, when the form is first opened, it shows all the records that be searched. Is there any way that I can stop this? I just want the subform to be blank until a search is ran.

I currently have a database which has a fairly simple form linked directly to a table, which records staff attendance information.
It generally works really well, however there is one thing I would like it to do, which is be able to hide certain records from view (rather than delete them completely).
I have a checkbox on the form (bound to a corresponding field on the table) called chkHide (the field in the table is called hide), which is not visible in form view; I have a button that is visible and when pressed by a user it will change the value of the check box to True.
So far so good. However, I would then like to have the form refresh and when it does so no longer show the record to the user (so it looks like it has been deleted, but in fact that record remains in the table).
I have tried applying a filter on load, but I don't know what expression to put in the Filter on the Property Sheet - - I have tried [Hide] = Is Null, but that isn't right. I have also created a Query where I have set the criteria for the field 'Hide' to Is Null and then put the name of the query in the Filter box - that doesn't work either, as it will let me put in new records but not let me see any of those put in before the form was refreshed.

When I add new records to the form and close the form, the tables are updated with the new records, but the new records don't show in the form (navigation).

I have search filter form that when I click the search button is passing a value in OpenArgs to the Main Form on open event. The OpenArgs is changing the recordsource of the subform on the main form appropriately. However, the main form is referencing all of the records, not just the ones that are int eh subform recordsource. My link master and child fields are correct. There is a 1:N relationship between my mainform table and subform table.
For example, my my subform, the recordsource is diplaying 2 records where the Status = BLUE, however, the mainform (Projects) is showing ALL records even where the status isn't blue. So when I scroll through the mainform records, if the project isn't status = blue, the status subform shows a blank record. I only want the Projects where the status is blue.

I have a chart that shows the amount of complaints every month in the last year of a selected costumer. The goal is to see if the amount of complaints from this costumer is decreasing or increasing.
The problem is that some smaller costumers have months without complaints (in real life that isn’t that bad). But my graph only displays a dot for the months were the amount of complaints is not null. This makes that the graph line doesn’t show the complete picture.
I know that I should be able to solve this with an ISNULL expression. I have tried the following SQL code as Row Source of the graph:
SELECT (Format([Complaintdate],"MMM 'YY")), ISNULL(Count([Complaintnumber])),0 AS [CountOfComplaintnumber] FROM [Complaints] WHERE [Complaintdate] > (Date() -365) AND [Costumername] = Forms!Report_complaintscostumer!Combocustumername GROUP BY (Year([Complaintdate])*12 + Month([Complaintdate])-1),(Format([Complaintdate],"MMM 'YY"));
The result of this is that all the months with complaints now get a 0 value and still the months without complaints aren’t shown.
What am I doing wrong? Could someone help me solve this problem? Any help is greatly appreciated!

I have a list of departments, 1-17, where each needs a SUM of their price for each end of day.
At first I was going to make 17 queries, and place each into a new sub-report, but there must be a way to list all 17, even if they haven't had a sale put through.
I've tried linking using "show all values in tblDept and only those that match in tblOrder" - but I cam across a very obvious issue.
The items are grouped by Z1 Number, a unique number for the end of day sales. If there is no department linked to a Z1 number, then it won't show it. For example, if there were no sales in dept01, then there is no record under tblOrder to show a Z1 number for dept01 - so there is nothing to link to in the report.
I was then thinking of creating false data at the end of day so the Z1 number mentioned each department at least once, but that would get messy and not 'normal'
I'm thinking of a type of loop to generate the report so a 17 row report is generated,

I am using workdays to calculate time passed between two dates. I also have a table for Holidays that I don't want counted as work days. This is working well, but I would like my queries to show a null value instead of showing #Error when a date field is empty. Here is my coding in my Module.
Option Compare Database
Option Explicit
Public Function Workdays(ByRef startDate As Date, _
ByRef endDate As Date, _
Optional ByVal strHolidays As String = "Holidays" _

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.

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.

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.

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?

This is so weird.
I have a form that I built and is based on a relationship between four different tables. I can enter info into the form, save it, and verify that it saved to each of these tables. The problem is that once I close the form and re-open it, none of the previously entered info shows up. Bottom of the page shows 1 record, but I can still see all of the info when I open the tables. Please help.

Hello. This is a very basic question. I have a query that has relationships set within. Now.. When I pull up the query with a criteria such as "date" ... the query pulls up all the information for only the items that have all the related fields filled in. How would i make this query show ALL the items from that "date" even if their related fields are blank or there are no relationships in another table?
Please let me know.

Just setting up the query filters in MS Access 2007, by simply going into the design view for that particular query, setting the criteria, so really can't see how it isn't working? I put Like "*TOF*" in the criteria field and no records are returned for that, even though there's many records including that word in that field?

Hi, I hope someone can help me. I have a database as thus:
Several tables ->appended together using 'union select' into a query called 'sheet1'-> information that is coded converted via linked tables in a query called 'sheet2'
'Sheet 2' looks completely fine - it works dandy but when I try and run a pivot table not all of the values in one column that should show don't even come up as an option.
The values that are missing on the pivot report do actually exist in the query that it is running from.
There are no filters on and Pivot tables work okay on the origional tables.
Has anyone had anything similar?
Help would be most appreciated,
Thanks,
Erica

Hi All
I have a feeling that this is an absolute newbie question.
I have three queries, qryVisitsDue, qryVisitsOverDue, qrySiteView.
The query qrySiteView uses SiteID to produce a listing of all sites which includes a count of visits for those sites. If there is no visit data the site does not display. To display the counts I'm using the other two queries. In the first two I'm querying a table, tblVisits, to find what visits are due or overdue based on the current date. They work fine where there is visit data. My problems start when there is no data for a site. I need to be able to show the sites where there is no visit data.
I'm not very experienced so basic explanations are probably the best.
Any help much appreciated.

I have two tables, bad design, not my choice of the way it's set up.
Table a has Fields 1-2, dups allowed in all fields. No pk was originally assigned.
Table b also has the same fields 1-6, but also has field 6.
Table a has all of the records in question, table b only has some of the records from table a but does not have any records that are not in a.
Something like this.
Table a
Field1 Field 2 Field 3 Field 4 Field 5
John Shirt blue denim button
Mark pants green straight
John Shirt blue silk button
Table b
Field1 Field 2 Field 3 Field 4 Field 5 Field6
John Shirt blue denim button new
Mark pants green straight used
If I query the two tables, a left join to b, then I get the correct number of total records. If I select any records from b, then the total records goes higher than there are, even for the two combined, listing the same record multiple time.
Any suggestions are appreciated. I am a blood bank lab person, not an IT person, or DBA, so simple responses are greatly appreciated.

I am doing some ICT coursework and I a bit stuck.
I am creating a database that will allow users to log in and submit bids on houses. There are only a certain amount of house plots available, but I cannot seem to make the database find the top bidders within the plots available, for example the top 5 bidders or top 7 bidders, depending on how many plots available.
I have 4 fields, from two different tables. I have a bidder ID field, House Type ID field (which I use "[please enter house type ID"]), a bid amount field and Number of plots field.
I want the query to select the top "x" amount of bids that it says in the number of plots field, e.g. 5.
How can I do this for all the different house types?

I have a form "Training", with a combo box that holds employee names and a subform with all of their training records linked by "EmployeeID". Quite often lately, when the user selects their name from the combo and the code below runs, someone else's records appear in the subform. There doesn't seem to be any kind of pattern, ie. the previous employee on the list or the next, etc.
Private Sub Combo6_AfterUpdate()
' Find the record that matches the control.
Dim Rs As Object
Set Rs = Me.Recordset.Clone
Rs.FindFirst "[EmployeeID] = " & str(Me![Combo6])
Me.Bookmark = Rs.Bookmark
'Forms!Employees![Combined Subform].SetFocus
End Sub
I have the db split with both the FE and BE on the server and a batch file that runs from a link on our intranet. The table that holds all of the data is at 3,195 records and the db is just under 4MB. I compact/repair regularly.
There are 66 users - usually 3-4 concurrently.
Is it time to think about moving the BE to SQL or Oracle?
Thanks for any help you could offer.

A form I created contains buttons for the user to restrict the display- showing records that are tasked to one specific employee.
So their choices are Employee a, employee b or all employees.
This is a process I use a lot :)
This last form opens with NO records displayed. When a button is clicked the records show correctly.
Any idea what to check?
Thanks,
