The code below returns the wrong value for recordcount. It returns 1 and should be 3. Does anyone see an obvious problem?

Dim db As Database
Dim rst As DAO.Recordset
   
    Set db = CurrentDb
    Set rst = db.OpenRecordset("SELECT * FROM Temp_Sub_op_Time")
    If rst.RecordCount = 1 Then
        DoCmd.Close acForm, "frm_timeadj"
        DoCmd.OpenQuery "Del_temp_sub_op_Time"
        rst.Close
        Set rst = Nothing
        Exit Function
    End If
    rst.Close
    Set rst = Nothing

RecordCount is not the total count of records in your recordset. It is the absolute position.
 
 


To get the total number of records, you need to move to the last record, and then test recordCount.
 
 


ie:

rst.MoveLast
TotNumRecords = rst.recordcount
rst.MoveFirst
If TotNumRecords = 1 then...
0

Duh, Thanks. Actually, going back and reading my book, it says that. Sometimes, I just read what I want to. Thanks for the help.

Just to clarify, RecordCount is not the current position within your recordset, but it doesn't pick up its correct value until you've moved to the end of the recordset. So in the above example, assuming you've got 25 records in your recordset:

Set rst = db.OpenRecordset("SELECT * FROM Temp_Sub_op_Time")
At this point, rst.RecordCount=1

rst.MoveLast
rst.Recordcount now=25

TotNumRecords = rst.recordcount
rst.MoveFirst
rst.RecordCount is still=25, even though you've now gone back to the start of the recordset

Note that the only valid test using RecordCount - not to be confused with getting the record count - is testing it against zero:

IF rst.RecordCount = 0 Then
   'whatever
Else
  'whateverElse
End If

And you should always test for zero *before* executing a MoveLast or any Move because if it is zero, you will get an error on the Move.
