This article applies to a Microsoft Access database (.mdb) file or to a Microsoft Access database (.accdb) file.

Moderate: Requires basic macro, coding, and interoperability skills.

SYMPTOMS

When you try to open a database in Microsoft Access 2000 or a later version, you receive the following error message:

The database is in an unexpected state

CAUSE

This problem may occur when you use the Data Access Object (DAO) library to convert a database that you created in Microsoft Access 97 or an earlier version by using the CompactDatabase method. The CompactDatabase method may leave the new database in a partially converted state.

RESOLUTION

To resolve this problem, use one of the following methods.

Method 1: Use the Convert Database command when you have the original database

If you still have a copy of the original database in its original format, use the Convert Database command. To do this, follow these steps:

Access 2000, Access 2002, or Access 2003

  1. Make a backup copy of the original database.
  2. Start Access 2000 or a later version.
  3. On the Tools menu, click Database Utilities, click Convert Database, and then click To Access 2000 File Format.


Note If you are using Access 2000, only To Current Access Database Version appears on the Convert Database menu.

  1. In the Database to Convert From dialog box, click the database file name that you want to convert, and then click Convert.
  2. In the Convert Database Into dialog box, type the new name of the database file, and then click Save.

Access 2007

  1. Make a backup copy of the original database.
  2. Try to open that database.
  3. When you open an Access 97 or Access 95 file format .mdb database, Access displays the Database Enhancement dialog box. You are prompted to upgrade the database.
  4. Click Yes to upgrade the database to whichever file format you have selected as the default file format in Access 2007. After you convert the database, you can make design changes to the file in Access 2007. However, you can no longer open the database by using a version of Access earlier than the version to which you converted the database.

Method 2: Recover the database data and the database queries when you do not have the original nonsecured database

If you do not have a copy of the original nonsecured database in its original format and you have tried standard corruption troubleshooting techniques, try to recover the database data and the database queries. To do this, follow these steps:

  1. Make a backup copy of the original database.
  2. Start Access 2000 or a later version.
  3. Access 2000, Access 2002, or Access 2003
    • Click Blank Access database, type the new database name in the File name box, and then click Create.

    Access 2007

    • Click Office button, click New, click Blank Database, and then click Create to create a new blank database.
  4. Access 2000, Access 2002, or Access 2003
    • On the Insert menu, click Module. The Microsoft Visual Basic Editor starts, and a new module is created.

    Access 2007

    • On the Create tab, click the down arrow below Macro, and then click Module. The Microsoft Visual Basic Editor starts, and a new module is created.
  5. On the Tools menu, click References.
  6. In the Available References list, locate Microsoft DAO 3.6 Object Library, and then click to select the Microsoft DAO 3.6 Object Library check box.

    Note DAO 3.6 is also available on Windows XP Home Edition.
  7. To close the References dialog box, click OK.
  8. Paste the following code into the new module that you created.

    Sub RecoverCorruptDB()
        Dim dbCorrupt As DAO.Database
        Dim dbCurrent As DAO.Database
        Dim td As DAO.TableDef
        Dim tdNew As DAO.TableDef
        Dim fld As DAO.Field
        Dim fldNew As DAO.Field
        Dim ind As DAO.Index
        Dim indNew As DAO.Index
        Dim qd As DAO.QueryDef
        Dim qdNew As DAO.QueryDef
        Dim strDBPath As String
        Dim strQry As String
        
        ' Replace the following path with the path of the
        ' corrupted database.
        strDBPath = "C:\My Documents\yourDatabase.mdb"
        
        On Error Resume Next
        Set dbCurrent = CurrentDb
        Set dbCorrupt = OpenDatabase(strDBPath)
     
        For Each td In dbCorrupt.TableDefs
            If Left(td.Name, 4) <> "MSys" Then
                strQry = "SELECT * INTO [" & td.Name & "] FROM [" & td.Name & "] IN '" & dbCorrupt.Name & "'"
                dbCurrent.Execute strQry, dbFailOnError
                dbCurrent.TableDefs.Refresh
                Set tdNew = dbCurrent.TableDefs(td.Name)
                
                ' Re-create the indexes on the table.
                For Each ind In td.Indexes
                    Set indNew = tdNew.CreateIndex(ind.Name)
                    For Each fld In ind.Fields
                        Set fldNew = indNew.CreateField(fld.Name)
                        indNew.Fields.Append fldNew
                    Next
                    indNew.Primary = ind.Primary
                    indNew.Unique = ind.Unique
                    indNew.IgnoreNulls = ind.IgnoreNulls
                    tdNew.Indexes.Append indNew
                    tdNew.Indexes.Refresh
                Next
            End If
        Next
            
        ' Re-create the queries.
        For Each qd In dbCorrupt.QueryDefs
            If Left(qd.Name, 4) <> "~sq_" Then
                Set qdNew = dbCurrent.CreateQueryDef(qd.Name, qd.SQL)
            End If
        Next
        
        dbCorrupt.Close
        Application.RefreshDatabaseWindow
        MsgBox "Procedure Complete."
    End Sub
    

    Note The code will try to import all tables and all queries from the corrupted database into the current database. Replace C:\My Documents\yourDatabase.mdb with the correct path and file name of your database.

  9. To run the code, click Run Sub/UserForm on the Run menu.

Method 3: Recover the database data when you do not have the original secured database

If you do not have a copy of the original secured database in its original format and you have tried standard corruption troubleshooting techniques, try to recover the database data. To do this, follow these steps:

  1. Make a backup copy of the original database.
  2. Start Access 2000 or a later version.
  3. Access 2000, Access 2002, or Access 2003
    • Click Blank Access database, type the new database name in the File name box, and then click Create.

    Access 2007

    • Click the Microsoft Office Button, click New, click Blank Database, and then click Create to create a new blank database.
  4. Access 2000, Access 2002, or Access 2003
    • On the Insert menu, click Module. The Microsoft Visual Basic Editor starts, and a new module is created.

    Access 2007

    • On the Create tab, click the down arrow below Macro, and then click Module. The Microsoft Visual Basic Editor starts, and a new module is created.
  5. On the Tools menu, click References.
  6. In the Available References list, locate Microsoft DAO 3.6 Object Library, and then click to select the Microsoft DAO 3.6 Object Library check box.
