I have an Access 2003 database used to research unemployment claims. The main form contains a subform in datasheet view listing the employee claim records, including employee Social security number. I would like them to be able to double Click a record in this datasheet and have it open a subform, populated from a Query that is passed the SSN from the recordset that was clicked. I have included the following code in the vba: - Private Sub Form_DblClick(Cancel As Integer)
-
DoCmd.OpenForm "ClaimDetail", , , "[SSN] = " & Me!ImportSsN
-
-
End Sub
The form does open on double click, if I look at the for properties, the filter is set to the correct SSN, but the records will not display. I know I am missing something obvious, please help.
3  3608 
OK, Never mind - this was a stupid error, have to treat the SSN as a string, so code should be : - DoCmd.OpenForm "ClaimDetail", , , "[SSN] = '" & Me!ImportSsN & "'"
I hate dynamic sql...:)

One of the most popular (frequently occurring rather than best liked) problems we get is with SQL strings being manipulated in VBA code.
The reason this is so difficult is that all the work is being done at a level of redirection. What I mean by this is that the coder is never working directly with the SQL itself, but rather with code which in turn, is relied on to produce the SQL that they are envisaging is required. It's rather similar to the problems coders have historically had dealing with pointers.
Anyway, a technique I often suggest to coders struggling with this (at any level. This happens to experienced coders too.) is to use either the MsgBox() function, or Debug.Print into the Immediate Pane of the debugger window, to display the value of the SQL in the string before using it (That's assuming you're not good with debugging generally. Personally I would trace to the line, then display the value prior to allowing execution of the string - See Debugging in VBA). It's really much easier to appreciate what a SQL string is meant to do, and where there may be problems, when you can see it in its entirety, and in its true form, rather than as the code is about to create it.

Hi,
I am working on a genealogy project in which I have two tables:
Person -- one record for each person in the family. Each record has a
unique Autonum field (IDPerson).
Partnerships -- one record for each marriage. Each record has a unique
Autonum field (ID), and also contains two fields IDPartnerMale and
IDPartnerFemale. Both of the latter fields match records in the Person
table via IDPerson.

Hi,
I have two very similar forms each with a subform. The main form gets
a few fields from the user and passes this back to a query that the
subform is bound to. The requery is done when the user enters the
last qualifying field on the main form.
In one case this works fine, the subform shows the data the user wants
to update -- which means showing all the data put in previously (ie
showing this via the requery and the continuous...

Hi All,
I have a listbox on a main form. When user double-clicks an item in

This is a work-in-progress, but seems to be working ok.
On my subform I have a sequence number field. When user selects from
the listbox, and the values are moved to the subform, I need to

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
