Examples of LobCreator

org.hibernate.engine.jdbc.LobCreator
Contract for creating various LOB references. @author Steve Ebersole @author Gail Badner
org.springframework.jdbc.support.lob.LobCreator
Interface that abstracts potentially database-specific creation of large binary fields and large text fields. Does not work with java.sql.Blob and java.sql.Clob instances in the API, as some JDBC drivers do not support these types as such.
The LOB creation part is where {@link LobHandler} implementations usuallydiffer. Possible strategies include usage of PreparedStatement.setBinaryStream/setCharacterStream but also PreparedStatement.setBlob/setClob with either a stream argument (requires JDBC 4.0) or java.sql.Blob/Clob wrapper objects.
A LobCreator represents a session for creating BLOBs: It is not thread-safe and needs to be instantiated for each statement execution or for each transaction. Each LobCreator needs to be closed after completion.
For convenient working with a PreparedStatement and a LobCreator, consider using {@link org.springframework.jdbc.core.JdbcTemplate} with an{@link org.springframework.jdbc.core.support.AbstractLobCreatingPreparedStatementCallback}implementation. See the latter's javadoc for details. @author Juergen Hoeller @since 04.12.2003 @see #close() @see LobHandler#getLobCreator() @see DefaultLobHandler.DefaultLobCreator @see OracleLobHandler.OracleLobCreator @see java.sql.PreparedStatement#setBlob @see java.sql.PreparedStatement#setClob @see java.sql.PreparedStatement#setBytes @see java.sql.PreparedStatement#setBinaryStream @see java.sql.PreparedStatement#setString @see java.sql.PreparedStatement#setAsciiStream @see java.sql.PreparedStatement#setCharacterStream
