## Changing database adapter
It's possible to change the protocol for DATABASE_URL by setting
the environment variable DATABASE_SCHEME on the app:
the environment variable MYSQL_DATABASE_SCHEME on the app:
```
dokku config:set playground DATABASE_SCHEME=mysql2
dokku config:set playground MYSQL_DATABASE_SCHEME=mysql2
dokku mysql:link lolipop playground
```
Will cause DATABASE_URL to be set as
mysql2://mysql:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
CAUTION: Changing DATABASE_SCHEME after linking will cause dokku to believe
the service is not linked when attempting to use `dokku mysql:unlink` or
`dokku mysql:promote`.
CAUTION: Changing MYSQL_DATABASE_SCHEME after linking will cause dokku to
believe the service is not linked when attempting to use `dokku mysql:unlink`
or `dokku mysql:promote`.
You should be able to fix this by
- Changing DATABASE_URL manually to the new value.
OR
- Set DATABASE_SCHEME back to its original setting
- Set MYSQL_DATABASE_SCHEME back to its original setting
- Unlink the service
- Change DATABASE_SCHEME to the desired setting
- Change MYSQL_DATABASE_SCHEME to the desired setting
- Relink the service
