Operation must use an updateable query. (Microsoft JET Database Engine)

This is one of the most common ASP errors that occurs when the data is being updated in a Microsoft Access database that doesn't have sufficient access privileges.

Solution

• In Windows 98 or ME: Right click on the MS Access file (.mdb) and uncheck the "Read-only" property.
• In Windows NT, 2000 or XP: Ask your system administrator to setup full access permissions for the anonymous user account called IUSR_<Machinename> to access the database.

If you are hosting your website externally, your web hosting company most likely provides a special read-write folder for databases or will create one for you. Please check their FAQ and other information on your hosting company's website or contact them directly.
