It is possible to use Microsoft Access as a client – or as an intermediary for Visual Basic code – while using MySQL as the database engine. This provides a somewhat less bumpy migration path for VB/VBA applications.
The basic technique is to set up your MySQL server as a data source via ODBC. (I'll post more about that later, but it's fairly intuitive. Under Windows 98, ODBC data sources are created and configured with the "ODBC Data Sources (32 bit)" in the Windows Control Panel; the process should be similar for later versions of Windows. Once you've created a source, you link to its tables with Access.)
Notes
ODBC appears to translate data types it doesn't understand into Memo fields. This would be fine, except that you can't sort on Memo fields – so you may have to use types which ODBC can handle better. Fields which can't be sorted on also can't be designated as indexes in the data schema (on MySQL's end), or Access will refuse to import the table.
| MySQL type | MS Access type | Notes |
|---|---|---|
| TINYTEXT | Memo | |
| VARCHAR(255) | Text | field size = 255 |
(I'll add to this table as more examples come up.)
