Examples of org.hsqldb_voltpatches.types.JavaObjectData

org.hsqldb_voltpatches.types.JavaObjectData
Represents of an instance of an OTHER field value.
Prior to 1.7.0 there were problems storing Objects of normal column types in columns of the type OTHER. In 1.7.0 changes were made to allow this, but as all the conversion took place inside the engine, it introduced a requirement for all classes for objects stored in OTHER columns to be available on the runtime class path of the engine.
In 1.7.2, the introduction of real preprared statement support allows us revert to the pre 1.7.0 behaviour without the artificial limitations.
The classes for stored objects need not be available to open and operate the database in general. The classes need to be available only if a conversion from one of these objects to another type is performed inside the engine while operating the database. The current limitation is that in SQL statements, values of type String (CHARACTER and related SQL types) cannot be stored in columns of type OTHER. This limitation does not exist for String values assigned to PreparedStatement variables. @author Fred Toussi (fredt@users dot sourceforge.net) @version 1.9.0 @since 1.7.2
