Im messing around trying to learn Access and have hit a problem.
I have a table called tblbookings and i want to seach though it when trying to make a new booking to make sure the room isnt alrady booked.
In tblbookings i have a room_number, booking_start_d ate and booking_end_dat e
Ive tried all sorts of code but it either brings up an error or doesnt do anything at all. Hoping someone can help.
Ive got as far as bringing up a message box if it finds the same room already in the booking table (which obviously isnt very useful but its as far as i can get!)
Im using the following code:
Can someone have a look and tell me what i should be doing. Cheers
If Me.NewRecord = True Then
Dim strWhere As String, strmessage As String
strWhere = "Room_Numbe r = " & Me!Room_Number
Me.RecordsetClo ne.MoveFirst
Me.RecordsetClo ne.FindFirst strWhere
Do Until Me.RecordsetClo ne.nomatch
If Me.RecordsetClo ne!Room_Numnber = Me!Room_Number Then
MsgBox ("test")
Cancel = True
Exit Sub
End If
Me.RecordsetClo ne.FindNext strWhere
Loop
End If

Try this :- - If Me.NewRecord = True Then
-
Dim strWhere As String, strMessage As String
-
Dim rsClone as RecordSet
-
-
strWhere = "((Room_Number=" & Me.Room_Number & _
-
") AND (Booking_End_Date>=#" & _
-
Format(Me.Booking_Start_Date,"m/d/yyyy") & _
-
"#) AND (Booking_Start_Date<=#" & _
-
Format(Me.Booking_End_Date,"m/d/yyyy") & _
-
"#))"
-
-
set rsClone = Me.RecordsetClone
-
rsClone.MoveFirst
-
rsClone.FindFirst strWhere
-
-
If rsClone.NoMatch then
-
MsgBox ("test")
-
Cancel = True
-
Exit Sub
-
End If
-
End If

Why would it not?
That's what the complicated stuff in the WHERE clause is for.
Do you say that after testing or is it what you'd expect to happen?
yes thanks
was me being silly!

rooms on the next page.
The three tables involved in this function are:

I work for a small hotel. They don't want to invest in a good front desk
program and the paper system that is being used is not working. It is
complete chaos at the moment. I want to make a database or program that
will be able to manage the guest register and reservations. It doesn't have
to handle payments at this stage. Preventing overbookings is a critical
priority at the moment because it is going into high season here in Florida....

I'm building a bookings database for trucks that among other things
captures the TruckName, LoadDate, LoadTime, UnloadDate and UnloadTime.
Is there a simple way to prevent double bookings for any particular
truck so that when a new entry is being added, if the LoadDate and
LoadTime doubles up with an existing entry I can flag it to the user?
