Determing Empty Tables or Queries in MS Access

You can determine whether an Access table or query, accessed via RECORDSET OBJECT, contains any record by examining the boolean type BOF and EOF property of that RECORDSET OBJECT. If the RECORDSET contains no record or is empty, then the value of both properties is TRUE, that is, BOF = TRUE and EOF = TRUE.

Call the following function to minimize your program code:

 Function Recordset_Empty(Rs as Recordset)

    Recordset_Empty = False
    If Rs.BOF And Rs.EOF Then  
Recordset_Empty = True End Function
If RECORDSET OBJECT is empty, then this function returns TRUE. Otherwise, it returns FALSE. Example:
 Dim DatabaseName as string
Dim rs Personnel as Recordset
Dim dbPayroll as Database

'Set the MS ACCESS database file name
DatabaseName = "C:\DATA\PAYROLL.MDB"

Set dbPayroll = DbEngine.Workspaces(0)
.OpenDatabasse(DatabaseName) Set rsPersonnel = dbPayroll.OpenRecordset
("PERSONNEL") If Recordset_Empty(rsPersonnel) then 'Table PERSONNEL contains no record Msgbox "PERSONNEL table is empty." EndIf
