• OnlineCompress: Implementation of SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE(). Code which implements the following system procedure: void SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE( IN SCHEMANAME VARCHAR(128), IN TABLENAME VARCHAR(128), IN PURGE_ROWS SMALLINT, IN DEFRAGMENT_ROWS SMALLINT, IN TRUNCATE_END SMALLINT) This system procedure can be used to force 3 levels of in place compression of a SQL table. The table is specified using the SCHEMANAME and TABLENAME arguments. If PURGE_ROWS is set to non-zero then a single pass is made through the table which will purge committed deleted rows from the table. This space ...
• Factory: Callers of these methods must be within the context of a Cloudscape statement execution otherwise a SQLException will be thrown. There are two basic ways to call these methods. Within a SQL statement. -- checkpoint the database CALL org.apache.derby.iapi.db.Factory:: getDatabaseOfConnection().checkpoint(); 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. This class can be accessed using ...
• Database: The org.apache.derby.iapi.db.Database interface provides "internal" methods on the database which are not available to JBMS users (org.apache.derby.database.Database, which this interface extends, provides all the externally visible methods).

There are a bunch of the unimplemninted interface that used to be in this file. They have been moved to old_Database.java. old_Database.java is checked into the codeline but is not built, it is there for reference
