radiusd.ServiceDatabase SQL has a number of customisable
               SQL statements (AddServiceQuery, GetServiceQuery, UpdateServiceQuery,
               DeleteServiceQuery, AddSubscriptionQuery, GetSubscriptionQuery,
               UpdateSubscriptonQuery and DeleteSubscriptionQuery). These statements are
               used to access the entries in the SQL Service Database. The default
               statements will work with the example SERVICES and SUBSCRIPTIONS tables in
               the example SQL schema in file goodies/hotspot.sql.
               If you wish, you can use more or fewer columns in your SQL Service
               Database, and you can change the names of the columns or the table. If you
               do use a different table schema, you will probably have to change
               statements to match your schema.ServiceDatabase
                  SQL uses by defining one or more DBSource, DBUsername and
               DBAuth lines. For more information about SQL configuration and failure
               behaviour, see Section 3.8. SQL configuration.ServiceDatabase SQL understands also the same
               parameters as ServiceDatabase xxxxxx. For more
               information, see Section 3.22. <ServiceDatabase xxxxxx>. It supports
               also all the common SQL configuration parameters. For more information
               about the SQL configuration parameters, see Section 3.8. SQL configuration.DeleteSubscriptionQuery DELETE FROM SUBSCRIPTIONS WHERE tenant_id=? AND id=? DeleteSubscriptionQueryParam %2 DeleteSubscriptionQueryParam %3
