Some new or updated features associated with DODS 5.1-13:

- (ID: ) Added connection close check on first write in transaction. - MySQL problem reported by Petr Stehlik.

- (ID: ) bug fix - now throws exception if sql batch affects less then 1 row.

- (ID: ) implemented optional PreparedStatement caching. MaxPreparedStatements=0 means thet DODS turns off PreperedStatement caching.

- (ID: ) Added new parameter in app config file : SQLBatch. This option enables executing modifications in transaction using addBatch and executeBatch methods.

- (ID: ) During cache initialization, cursor type can be overridden using new parameters InitCachesResultSetConcurrency, InitCachesResultSetType.

- (ID: ) PreparedStatement cache is enabled for modifications (updates, inserts).

- (ID: ) New addWhereIn methods in QueryBuilder (RDBColumn, Array of )

- (ID: ) fetch size problem with MSJDBC driver - added new method in query class which overrides values of cursor types parameters from application

- (ID: ) FullCacheCountLimit parameter - query checks current cache size and depends on this parameter DODS

- (ID: ) fetch size will be set automatically to 1 for uniqueInstace queries.

- (ID: ) getDO method in DBTransaction interface returns Transaction interface instead of CoreDO.

- (ID: ) Added new parameters - initCacheSize and initFetchSize - for loading caches first time.

- (ID: ) P6Spy - version 1.3 is included in DODS.

- (ID: ) Changes in name convention logic for named constraints (not only for foreign keys) in SQL _expression_ (uses ConstraintNameLength parameter)

- (ID: ) Added new interfaces ExtendedDBConnection and AbstractDBConnectionFactory to enable custom implementation of database connection (or ConnectionFactory class).
