The error message indicates that your database is full, which explains why you can't add data. This may mean that:
- Your disk is full.
- You've reached the database size limit of your SQL Server edition/version.
- The PRIMARY filegroup can no longer grow, because autogrowth has been disabled for instance.
You will need to either:
- Free up disk space.
- Clean up your database.
- Change your autogrowth settings.
- Move your database to a different SQL Server.
