I would like to select specific columns based on the user checkbox selection.
I can able to achieve it using VBA but is it possible to arrive the fields in SQL itself based on forms checkbox tick status?
Two ideas:
1) create a text box that collects the values of the checkboxes:
= if(checkbox1,"Col1, ","") & if(checkbox2,"Col2, ","") & ...
Create a second one that removes the tailing comma.
Use the content of this second text box to build your SQL string.
2) Solution 1 requires you to hard code the columns in one formula. A more generic way would be to populate a list with the column names of your data source (the table). The changed event of the list would then generate the list of column names for your SQL string.
This solution involves VBA, yes but it's interactive. Guess that's what you're after.

I am filtering a form named sfrWorklistFilter from a combo box named cboOpeningType. The recordsource is from an embedded query on the form. If I make a selection from the combo box the filter works fine with the following code:
Forms![sfrWorklistFilter]![cboOpeningType]
However I need to return all records when no selection is made in which case I use the following code:
Like Forms![sfrWorklistFilter]![cboOpeningType] & "*"
The filter then does not give exact matches, but all records that begin with the letter on the combo box.
I need exact matches for the record or if no selection is made all records.
Any suggestions?
EDIT remove double quotes
This should work - and you can do same thing with your other field/combobox searches
Like IIf([Forms]![sfrWorklistFilter]![cboOpeningType]<>"",[Forms]![sfrWorklistFilter]![cboOpeningType],"*")
I am trying to use Link Master Fields to get a value from my form in order to filter some of my data and then show the remaining on my chart. Everything works perfectly fine but when I want to select more than one value (using a listbox to select multiple values for a field), my chart returns nothing.
I would like to know how can I address multiple values for a field in my chart so it filters the values on my chart as an "Or" function in SQL.
Imagine I want to have an SQL with: WHERE [MyTable].[Field1]= Selected values in listbox.
It seems that my SQL selects all the values in the listbox as One Value/And function.
You will need to do this via VBA.
Use the Change event on the list box to update the subforms recordsource.
Also make sure you execute the code in the forms Current event, so that it will display correctly when moving records, and on initial opening.
So with a bit of research and trying out different ways, an easy way is to use some hidden textboxes in the form and loop through the selected values and give each textbox one of the selected values in the listbox.
From there you can write a SQL for your chart specifying the condition so your field = Condition 1 or field = Condition 2.
I have a field with a customer ID that should be in the format of C0000000001, where it has a letter at the start and up to 10 numbers after the letter with leading zeros between the letter and the number. I want the users to be able to put in C1 and have the table save C0000000001 or C1234 and have the table save C0000001234.
I want the restriction to be on the hard data in the table. The table should contain the full customer ID but I only want the users to have to enter the C and the number of the customer when entering/searching for customers. I am using Access 2010.
I believe that the first character will always be a C, but either way, it would only be one alpha character if it wasn't.
I understand what you are saying, but the majority of the data (thousands of records) are going to be from another system that stores them that way. Doing it this way limits my margin of error. Otherwise, exports from the other system will need to be manually changed prior to being imported into the database and vice versa.
Searching would only be on existing records that will be saved in the C0000001234 format, but I would like user to be able to omit the leading zeros when entering the search criteria.
This question, combined with your previous question here, suggest to me that you are trying very hard to have the data structure in your Access database exactly match the legacy system from which you receive bulk updates. That may not be necessary, or even desirable.
For example, instead of maintaining the CustomerId as Text(11) (as in the old system) you could store it in your Access database as
CustomerIdPrefix: Text(1), and
CustomerIdNumber: Long Integer or perhaps Decimal if the numeric part really can exceed 2,147,483,647
Your Customers table in Access could also include a calculated field named CustomerId as
[CustomerIdPrefix] & Right("0000000000" & [CustomerIdNumber], 10)
to give you a single 'C0000012345' value for display purposes.
For searching, your form could have a Text Box for the Prefix (default value: 'C') and another text box for the numeric part. The search could then use a condition like
[CustomerIdPrefix] = txtPrefix.Value AND [CustomerIdNumber] = txtNumber.Value
or, if the user wanted to create a Filter on the Form (or Datasheet View) it would probably be sufficient to just filter on the number part.
If you ever needed to feed information back to the legacy system you could just export a query that includes the [CustomerId] calculated field (and omits [CustomerIdPrefix] and [CustomerIdNumber]) and you'd be fine.
My suggestion would be to use forms with associated queries using the FORMAT function.
You do need to clarify where you want this implemented, but I'm going to assume you have a table set up and that you would like to be able to enter/search data from a form.
I'll create one form for input frmAdd. For the input form, I created a query that would run when a button on the form was pressed. Add two text boxes newID and newOther to the forms which are unbounded but which the user can use to enter data. The query will then pull that data and append it to your table in an altered format. Here's the SQL for that query:
INSERT INTO Customers ( [Customer ID], [Other Field] )
SELECT Left([Forms]![frmAdd]![newID].[value],1)
& Format(Right([Forms]![frmAdd]![newID].[value],Len([Forms]![frmAdd]![newID].[value])-1),"0000000000")
AS Expr1, Forms![frmAdd]!newOther AS Expr2
FROM Customers;
I'm not sure exactly what search functionality you're looking for, but this query would pull up the record data matching that of a frmSearch with a textbox search which would have the format C### or whatever entered in:
SELECT Left([Customers].[Customer ID],1) & Replace(LTrim(Replace(Right([Customers].[Customer ID],9),'0',' ')),' ','0')
AS Expr1, Customers.[Other Field]
FROM Customers
WHERE (((Customers.[Customer ID])=Left([Forms]![frmSearch]![search].[value],1)
& Format(Right([Forms]![frmSearch]![search].[value],Len([Forms]![frmSearch]![search].[value])-1),"0000000000")));
Applying the input mask is just a way to ensure that your data is correct. If you feel the need to use one, go to the table in Design View and click on the Data Type box for the customer ID field. Find Input Mask under Field Properties -> General and click it. Then hit go to the toolbar -> Design tab -> Builder. This will walk you through it.
Input mask is not the answer for this. Input mask forces the user to input the data in a certain manner. What you need is some VBA code to run in the AfterUpdate event on a form. There's no way within the table to force the data into this pattern allowing the input method that you've requested.
There may be a more efficient way to do this, but this does the job.

I have a lookup field in my table based on another table. I'm having trouble filtering those values based on another field that is entered prior to the field.
Is it possible to filter a lookup field based on another field?
EDIT
Let me try and clarify my original question, sorry about that. Ok, so I have a table1 that has the following fields: ID, Name, Logo.
If a user enters a specific name in the Name field, when they click on the Logo field, it'll only display those values associated that are similar to the name entered. Does that make any sense? If it does make sense, would there be an easier suggesion on accomplishing this task?
If you're talking about inside a table, the answer is "No". You can create cascading combo boxes on a form, but you can't base a lookup value in a field of a table off of a different field in that table (or the field in any other table).
Here is an example of how to handle filtering a combo box based on the value selected in another combo box:
I have the following form:
The combo boxes are named cboIntPN and cboManPN.
The Row Source for cboIntPN is set to: SELECT uniq_key, part_no, revision FROM inventor. The Row Source for cboManPN isn't set to anything.
When the user selects a value for Internal PN the following AfterUpdate Event is triggered:
Private Sub cboInternalPN_AfterUpdate()
[cboManPN].RowSourceType = "Table/Query"
[cboManPN].RowSource = "SELECT uniqmfgrhd, mfgr_pt_no FROM invtmfhd " & _
"WHERE uniq_key = '" & cboIntPN.value & "'"
End Sub
It sounds like he is having the same issue as me. I also wanted to filter a field in a table for data entry on another field's input and my conclusion is "it is time I stopped entering data manually in tables and begin to create Data entry forms. I was putting this task off until later, but if I don't do it now, I might make worse trouble for myself later.
Btw, what an old thread.
How do I bind a text box with a field, which doesn't belong to form's "Record Source" table, through the Design View?
Example: I have "Order.cust_id" (Record Source=Order) and I want to display "Customers.name". I believe it is trivial but I have no experience with MS Access. I tried to use the text box "Control Source" property but no luck.
One method would be to convert the text box to a combo box. Then set the row source to include both the cust_Id and the Customer.Name from the customer table. SQL statement example
Select Cust_ID, Name From Customer
Order By Name;
By setting the number of columns to 2 and the column widths; the first column as zero (i.e. "0;6") then the foreign key would be hidden from the user and the customer name would be displayed.
Note this method does force you to have limit to list set to true.
Also you do end up with a drop down list which may not be what you want.
You can use DlookUp as the control source of a textbox:
=DlookUp("[Name]", "Customer", "ID=" & Cust_ID)
Syntax: What to look up, table name, where statement
The Where statement should follow the rules for Jet SQL, which means that you must use delimiters if the field is text or date format.
Note that Name is a very bad name indeed for anything. I suggest you rename the field immediately before things get worse.
It can be useful to know the error(s).
You could create a new View (e.g. OrdersAndCustomerNames), select all the columns you want to use in the form, then instead of using the Order table as Record Source, you would just switch to OrdersAndCustomerNames. You say you have no experience with MS Access, so I am guessing you are not building anything huge and overly complicated, so I would do it this way. I am quite sure it can be done more elegantly but this will do for now.
