The following code doesn't check null condition in Scannedby field. The scannedby has text data type. The code gives me all the data where scandate=20130722 but doesn't check that scanned by can't be blank.
Code:
rs.Open "select count(*) from BatchTBL2 where scandate=20130722 and scannedby <> null", cn, adOpenKeyset, adLockOptimistic
j = rs.fields(0).Value
Me.Text11 = Nz(DAvg("[final whse-in diff]", "dbo_inventory", "[CAFETYPE]=" & Me.Text7 And "isnull(me.[DATE FIXED])=" & True And "isnull(me.DATE_IN)=" & True), 0)
I am getting a type mismatch error with this.
My question is:
1. is the syntax correct....
2. Is my way of checking for a value to be null correct....
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 am looking to check 3 sub forms for values and if they contain any then delete them. After a bit of googling I discovered that you should use recordset.recordcount - to which I tried but I get method or data not found - is this a valid method?
My code to which Im using is:
If Me.NoneChargeable_Admin_subform.Recordset.RecordCount >= 1 And Me.NoneChargeable_Manufact_subform.Recordset.RecordCount >= 1 And Me.NoneChargeable_Research_subform.Recordset.RecordCount >= 1 Then
DoCmd.RunSQL "DELETE NoneChargeable_Admin.*, NoneChargeable_Manufact.*, NoneChargeable_Research.* " & vbCrLf & _
"FROM NoneChargeable_Admin, NoneChargeable_Manufact, NoneChargeable_Research;"
End If
DoCmd.Close acForm, "NoneChargeableHrs_frm", acSaveNo
End Sub
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:

I am trying to build an email string and have been sucessful...although there are times when the Email Field in my table may not have a value....
Currently this creates an error....I am trying to test for Null and then SKIP that record if it is null and move on...
Any thoughts?
THe problem is that I can click the Msgbox that gives me the varialbe from strTo endlessly....I am stuck in the loop...it never gets to EOF???
It never even gets passed the first record it finds...
Something is messed up....
Anyone have any thoughts...

I want to check if data entered in a form field is existed
The form is bounded to a table
I used this code
If DLookup("Telegram_Number", "tbl_Violation_Of_Building", "Telegram_Number Like " & Forms!frm_Add_Violation_Building!Telegram_Number) Then
MsgBox ("number existed")
Me.Telegram_Number = ""
Else
End If
everything is ok but if the data is existed the database show the message and clear the field but i'm getting a Run-time error
'-2147352567(80020009)': the macro or function set to the beforeupdate or validationRule property for this field is preventing [ISF] from saving the data in the field
I guess the problem because the form is bounded to a table so he will save automatically
My solution is to unbound the fields and save the data via vba but is there any solution with a bounded form???
I have a field 'Payment Types' with values (Cash, Cheque, Debit/Credit Card) and a field 'Payment Received' which is Yes/No.
When putting the order through the user selects the payment type and ticks a box if payment has been received.
On a report for delivery drivers, the owner wants it simple for the driver... he wants all the payment types listed with a checkbox next to each one, then wants the appropriate box ticked if payment has been received.
So I need something on the report (or underlying query) which ticks the appropriate box, i.e.
If payment received = true then payment type checkbox = true.
Or should I put the payments into a separate table with both fields so multiple payment types can be marked as paid?
If I have about 9 Text fields, How would I go about checking to see if all of the text fields are empty, then hide all the fields, but if any of them have anything in it, show them all. Here is my code, but it doesn't work:

All,
Introduction (I case I'm doing this all wrong)
I have 1 huge table of data:
SysID
PersonData
"
"
"
"
AddressData
"
"
"
"
"
"
"
"
"
TelephoneData
"
"
"
"
Year (this is 1 or 2)
I'm taking each component Person, Address, Telephone info and making a compacted table of each (i.e. lots of Jane Does etc, appear in both years)
Each table with have a URN
I then need to update the big table with the URN so move onto another part of getting this data into a usable format.
Basically what follows is my question on how to get the URN's back into the table:
-----------------------------------------------------------------------
Is there a quicker way (or a way I'm not seeing) of doing the following.
I have a set of data 'tblDatabaseTable, say:
ID
Field1
Field2
Field3
Field4
In the database.
I have an imported file which will be tblImportTable, same deal without the ID:
Field1
Field2
Field3
Field4
I need to compare the data on each table:
SELECT * FROM tblDatabaseTable
INNER JOIN tblDatabaseTable
ON tblDatabaseTable.Field1 = tblImportTable.Field1
AND tblDatabaseTable.Field2 = tblImportTable.Field2
AND tblDatabaseTable.Field3 = tblImportTable.Field3;
Works great as long as all the fields have values in.
Is there a way to compare the tables and get results as:
Database
Ian MacConnell null
Import
Ian Macconnell null
Match!
without doing something like:
SELECT IIf(IsNull([Field1]),' ',[Field1]),
IIf(IsNull([Field2]),' ',[Field2]),
IIf(IsNull([Field3]),' ',[Field3])
FROM DatabaseTable
SELECT IIf(IsNull([Field1]),' ',[Field1]),
IIf(IsNull([Field2]),' ',[Field2]),
IIf(IsNull([Field3]),' ',[Field3])
FROM ImportTable
before comparing them???
Phew, hope that all makes sense, very long day and I'm........
Cheers,
I have a form with couple of textboxes bound to a table. When the user opens the form to enter records, i want to write a function that would go through the textboxes to check whether the textboxes are left NULL. Now i can write code on button click for each form, but i was wondering if its possible to write a function that could be called for each form that i have to check for null values.
View 7 Replies View RelatedThere is a text box in a form that user can enter the value.
How can I check if the value entered by user is already existed in the record of the linked table or not?
If the value (or record) do not exist, that new value/record will be added to
the table.
If the value do exist, just show the msgbox to indicate.
How can I do that ? :confused:
Thanks

I have been working on an application where I am collecting survey data in a database. There are multiple survey tools available to the user, and it's possible to complete multiple survey tools in the survey.My problem is, it's possible for the surveyor to complete some tools on one day and other tools on another day. I am having problems with trying to figure out how to add a tool that has not been previously added and keep in the same survey which is all held under a single Survey Number.
The first step in the function is to set a Record Number temporary variable based on whether or not the tool has been used (it's possible to use multiple instances of a survey tool, so need to know if the Record Number is '1', or the next number in the sequence.I've been trying to do this by checking a query for a Null and setting the temporary variable using something like:
IF ISNull("RecordNumber","qryRecordHeader") Then '1'
Else
DLast("RecordNumber","qryRecordHeader") +1
End IF
The second half works just fine, so if there is a previous record, it will add. But if it's Null, it doesn't work.I'm trying to avoid opening a temporary form to run the query and checking a field. Is there a way around that?
So on a command button I have this code in the OnClick event. When I click the button it will ask me to enter the name if blank but if I enter something in that field and then delete the data is bypasses this. Does the same reason field, Why?
Code:
If IsNull(Me.CE) Then
MsgBox "Please enter your name"
Me.CE.SetFocus
Exit Sub

I have a Form with multiple comboboxes and listboxes whose selections are assembled into a query. The combo-box selection goes into an IF-ELSE statement for a selection check (IsNull) and if there is no selection made, it is supposed give me all values (Blanks & Non Blanks)
Here is a sample of my code:
Code:
If IsNull(Me.cbReg.Value) Then
RegStrng = " Like '*'"
Else
RegStrng = Me.cbReg.Value
RegStrng = "= " & RegStrng
End If
I have several If-Else statements here and a final query assembly at the bottom of the code page which is as follows
Code:
MasterSql = "SELECT DISTINCT blah-blah-blah" & _
" INTO some more blah-blah" & _
" FROM even more blah-blah-blah" & _
" WHERE dbo_mytable.[Reg#]" & RegStrng & _
" AND the results from other If-Else statements similar to above"
Here is where the problem comes in:
I see the mistake in my If-Else statement
Code:
If IsNull(Me.cbReg.Value) Then
RegStrng = " Like '*'"
Like * means it will show me all rows where there are NON-Blanks. However, it skips all Blank Data.
What should the If IsNull() statement look like if I want to show all the values?
If there was only one combo-box and there was no selection made, then the resultant query should show me all results rather than only the results where there is some sort of data within the column filtered by the combobox.
I have a multi-select listbox (called PotentialItems) which behaves perfectly unless one of the fields has a null value in it, in which case I get an error 13, "Type mismatch" in the following code. It is valid business-wise for column 9 to be null.
Code:
Dim varItem As Variant
Dim dblTargetPrice As Double
With Me.PotentialItems
For Each varItem In .ItemsSelected
If Not IsNull(varItem) Then
dblTargetPrice = Nz(.Column(9, varItem), 0) '<----- Error here
End If
Next
End With
I am currently working on an instrument datebase, I have a mainquery that takes care of user inputs from a form. The main fields that have been queried on are Type, System, and Manufacturer and they are all look-up fields that contain some null values.
On the same criteria row for these fields, I have
Like IIf([forms]![User Interface].[qtype2]="","*",[forms]![User Interface].[qtype2])
Like IIf([forms]![User Interface].[qsys2]="","*",[forms]![User Interface].[qsys2])
Like IIf([forms]![User Interface].[qman1]="","*",[forms]![User Interface].[qman1])
qtype, qsys and qman are the user inputs from the user interface that returns look-up table values.
This works fine when all 3 of these fields are all filled out for a certain instrument. The problem arise when some fields of the instrument are left blank or is null. The instrument won't show up in a query at all. What I wanted it to do is to show everything including the ones with null fields when the user input are null or "". When the user specifies certain requirement I only want to show the ones that are not null. I understand that putting them on the same row means AND, I have tried to OR them and did not have the result i wanted.
Access 2010..One organization that we work with provides us with a block of numbers for each of the two types of contract products we order from them; we do order non-contract stuff from them also.The block of numbers are the same (i.e. 20000 to 30000 this year) for each of the two products. This means that each product can have the number 20000, for example. We call this the Tracking Number. If it is one of these products, we need to select the Contract Number.
For all other one off orders we have with them, we assign our own Tracking Number starting with 00001. This Tracking Number cannot duplicate unless it is one of the aforementioned two products.Both the Tracking Number and Contract Number are in the same table. The user selects the Contract Number from a form (connected to the Contract Number table that has all the details on the contract) and the Contract Number is populated in the same table that has the Tracking Number.Each order must have a Tracking Number (no null)..Not all orders need a Contract Number (null okay).The Tracking Number and Contract Number combination cannot duplicate.I tried setting the primary keys to more than one field in the table, but they cannot have null values.
If not... I have been working on Plan B.... an AfterUpdate on the form (either the form or a field... don't know yet) that looks at a query that only has results if there are duplicate values.
Hi,
I have a form in a database for our products (doors). I have a button that duplicates one of these records (all new products are based on standard template records).
When this record is created a new product number is produced by the system which was the number of the original (template) record plus the customer enquiry number.
I want to be able to warn the user if they are trying to save this newly created record with a product number that already exists so that they can alter the number to be unique. It will also warn them if they re-number an existing record to another already existing product number. Since the field is defined as unique, at present the system says absolutely nothing and just doesn't save the newly created record which seems is a touch annoying!
I have tried several things with dlookup, dcount arguments but can't seem to get anything to work.
Hopefully someone here can point me in the right direction?
Thanks in advance

how to make this two fields in my form to say Y or N if the field is Not Null. Like if the field is not null = Y Else = N for the two fields. I have a picture to show what i'm talking about.
View 2 Replies View RelatedI have a form with two list boxes on it: listAllBANANA and listActiveBANANA
The listboxes are populated from tblBANANA. Active is defined by the tblBANANA field "ResponseDate" being Null.
Also on the form is a CloseBANANA command button. When pressed with no selection, it opens frmCloseBANANA to the first record. If a BANANA is selected in listActiveBANANA, the form opens to the selected record.
Now comes the tricky part: if a BANANA is selected in listAllBANANA, I first need to verify they have an Active BANANA selected, before opening the form. I've poked and tested and searched and cut and pasted my little fingers off with no joy. What I've deduced is that I'm either messing up the syntax of the DLookup or I'm incorrectly referencing the selected record. There's also the third option that I'm going about this in entirely the wrong way.
All other code below works. If I delete or comment out the line in red, I have no issues other than I may open up a blank form because I'm trying to close a BANANA that is already closed.
Code:
'If a BANANA is selected in Active BANANA or All BANANA, open Close BANANA to that record. If not, open form to most recent record

On a push of a button from a form, I want to locate specific records within the table and update a field to Null if it matches a name
Dim strSQL As String
strSQL = "UPDATE tblmaster SET Score = "" WHERE [AdvocateName] = 'Anna Maria'"
DoCmd.RunSQL (strSQL)
I'm certain I don't have the syntax correct between the Set to Null and WHERE clauses..
I'm new to programming with Access but am attempting to create a new field in a table with an new date based on existing fields in the table.
The current fields are [Frequency], integer, [Risk], text, [Last Audit Date], date/time, and the new field is [Next Audit Date]. [Frequency] is a calculated field based only on [Risk] and is equal to "5" if [Risk] is "Low" and is "3" is [Risk] is "Medium" or "High", and [Frequency] is blank if [Risk] is (thus far it has never been empty).
What I need the new calculated field to do is return "N/A" (or blank, or anything easily separated really) if [Frequency] is blank, or if [Risk] is "Low" or "Medium". If [Risk] is "High", [Next Audit Date] should be equal to [Last Audit Date] plus 3 years. When I try to save the code, I get this message: "The expression could not be saved because its result type, such as binary or NULL, is not supported by the server."
This is my code now:
IIf(IsNull([Frequency]),"",IIf([Risk]="Low","N/A",IIf([Risk]="Medium","N/A",IIf([Last Audit Date]="N/A","N/A",[Last Audit Date]+Year(3)))))
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
