Class EmbedSavepoint

java.lang.Object

org.apache.derby.impl.jdbc.ConnectionChild

org.apache.derby.impl.jdbc.EmbedSavepoint

All Implemented Interfaces:

Savepoint

final class EmbedSavepoint
extends ConnectionChild
implements Savepoint

This class implements the Savepoint interface from JDBC 3.0. This allows to set, release, or rollback a transaction to designated Savepoints. Savepoints provide finer-grained control of transactions by marking intermediate points within a transaction. Once a savepoint has been set, the transaction can be rolled back to that savepoint without affecting preceding work.

Supports

• JSR169 - no subsetting for java.sql.Savepoint
• JDBC 3.0 - class introduced in JDBC 3.0
