Hi there. Does anyone know how to execute an SQL select statement on a MDB database, and return a value to a VB variable?
For example, If I was to execute 'select UserName from users where UserId = 123' on the database, how could I get the result into a VB variable?

Try this:
Dim db As Database
Dim rs As Recordset
Dim strUserName As String
Set db = Workspaces(0).OpenDatbase("C:\MyDB.mdb")
Set rs = db.OpenRecordset("Select UserName From Users Where UserID = 123", dbOpenSnapshot)
If rs.EOF And rs.BOF Then
MsgBox "User doesn't exist"
Else
strUser = rs(0)
End If
strUser now holds the name of the user.

Hmm, how interesting. That indicates that the default for recordsets is "fields".
I always use:
strUser = rs.fields(0)
If you don't care about the returns from the recordset select, you can do the following conditional in place of Serge's
if isnull(rs.fields(0)) then
msgbox "user doesn't exist"
else
strUser = rs.fields(0)
end if
