ACC2000: How to Recover a Table Deleted from a Database

• Microsoft Access 2000

SUMMARY

This article shows you how to create a sample Visual Basic for Applications function that you can use to recover a table deleted from a Microsoft Access database under the following conditions:

• The database has not been closed since the table was deleted.



• The database has not been compacted since the the table was deleted.



• The table was deleted using the Microsoft Access user interface.

MORE INFORMATION

The following sample function recovers the last table deleted within a Microsoft Access database. To create the sample function, follow these steps.

NOTE: These steps assume that you are creating the sample function for future use. If instead you are adding the code directly to a database in which a table has recently been deleted, skip step 1, because if you have closed Microsoft Access or the database, you cannot recover the deleted table.

1. Open your database in Microsoft Access.



2. In the Database window, click Modules under Objects, and then click New.



3. Type or paste the following code in the module that you have just created:




Function Undo()

  Dim db As DAO.Database, strTablename As String
  Dim i As Integer, StrSqlString As String

  Set db = CurrentDb()

  For i = 0 To db.TableDefs.Count - 1

  If Left(db.TableDefs(i).Name, 4) = "~tmp" Then
     strTablename = db.TableDefs(i).Name
     StrSqlString = "SELECT DISTINCTROW [" & strTablename & _
       "].* INTO MyUndeletedTable FROM [" & strTablename & "];"
     DoCmd.SetWarnings False
     DoCmd.RunSQL StrSqlString
     DoCmd.SetWarnings True
     MsgBox "A table has been restored as MyUndeletedTable", _
       vbOKOnly,"Restored"
     GoTo Exit_Undo
  End If
  Next i
  MsgBox "No Recoverable Tables Found", vbOKOnly, "Not Found"

  Exit_Undo:
     Set db = Nothing
     Exit Function
  Err_Undo:
     MsgBox Err.Description
     Resume Exit_Undo

End Function 

4. On the Debug menu, click Compile database name.



5. Save the Module as RecoverTable. To test this function, type the following line in the Immediate window, and then press ENTER:
