When you convert a database from an earlier version of
Microsoft Access to Microsoft Access 2002, to Microsoft
Office Access 2003,
or to Microsoft Office Access 2007, you may receive the
following error message:
There were compilation errors
during the conversion or enabling of this database. The database has not been
saved in a compiled state. The performance of this database will be impaired
because Microsoft Access will need to recompile the database for each
session.
For information on improving performance, click Help.
In rare instances, the conversion utility may not convert some
Access Basic code to Visual Basic for Applications code. For example, it may
not change a
DoCmd statement
into a method of the
DoCmd object:
Conversion Errors
To see where the error or errors occur, compile all modules in
the converted database.
Note For compilations that do not have any errors, you may still have
to manually change some syntax in the database after conversion.
To
compile all modules in a converted database, follow these steps:
- Open the converted database in the new version of Microsoft
Access.
- Open a module in Design view.
- On the Debug menu, click Compile <Database Name>.
As Microsoft Access compiles your code, it stops at any line
that contains an error. You can then modify the syntax to resolve the
compilation error.
Incompatibilities with Certain Objects
If the conversion process seems to stop, takes a long time to
finish, or displays an error that prevents the new database from being created,
you can create a new database in Access
2002 or
in later versions. You can then import objects
(individually or grouped) from the database in the earlier version.
Importing objects into a new database has two benefits:
- You can speed the conversion process by importing groups
of objects. If you have a large database, the conversion process may be slow or
may appear to cause your computer to stop responding. Importing groups of
objects requires less memory and, in some cases, may be faster.
- You can determine which objects are incompatible with Access 2002
or with later versions. If an object cannot be imported,
you know to examine it more closely for a potential incompatibility. If an
object is imported successfully, it is automatically converted to the new
version.
NOTE: In rare instances, corruption in an object may cause
incompatibility with the later version of Access. If you suspect corruption, do
not import that object. Instead, re-create it in the later version of Access.
If the object is a Visual Basic for Applications procedure, try copying the
text to a Notepad file. Then, copy it from that file later and paste it into a
new module in the later version of Access.
To use the
Import command instead of the
Convert Database command, follow these steps:
- In
Access 2002 or in Access 2003, create
a new Access database.
- On the File menu, point to Get External Data, and then click Import.
- In the Import dialog box, click Microsoft Access in the Files of type box.
- Click the arrow to the right of the Look In box, select the drive and folder where the Microsoft Access
database (.mdb) that you want to import is located, and then double-click the
icon of the database.
- Click one or more objects to import. For example, you may
want to import the objects in groups of 20.
- Click OK to import the selected objects.
- Repeat steps 2 through 6 until you have imported all the
objects into the new database.
In Access 2007, follow these steps:
- In Access 2007, create a new Access database.
- Click the External Data tab, and then
click Access in the Import group.
- In the Get External Data – Access Database
dialog box, click Browse to select the Microsoft Office Access
2007 database (.accdb), click Open, and then click
OK.
- In the Import Objects dialog box, select
the objects that you want to import, and then click OK.
- Repeat steps 2 through 4 until you have imported all the
objects into the new database.
Errors in Code in the Earlier Version
To reduce the number of errors that may occur during the
conversion process, recompile all modules in the earlier version database. Then
correct any errors before you convert the database.
