Callers of these methods must be within the context of a Derby statement execution otherwise a SQLException will be thrown.
There are two basic ways to call these methods.

1. Within a SQL statement.

                   -- checkpoint the database
                   CALL org.apache.derby.iapi.db.Factory::
                                   getDatabaseOfConnection().checkpoint();
     

2. In a server-side JDBC method.

                   import org.apache.derby.iapi.db.*;
   
                   ...
   
           // checkpoint the database
               Database db = Factory.getDatabaseOfConnection();
                   db.checkpoint();
   
     

This class can only be used within an SQL-J statement, a Java procedure or a server side Java method.
