That makes the JDBC API the only API for working with databases.
The driver is a native protocol all-Java driver (type number four of types
defined by Sun).
This section provides reference information about 's
implementation of the JDBC API and documents the way it conforms to the JDBC
2.0, 3.0, and 4.0 APIs.
See the for
task-oriented instructions on working with the driver.
This JDBC driver implements the standard JDBC interface defined by Sun.
When invoked from an application running in the same JVM as ,
the JDBC driver supports connections to a database
in embedded mode. No network transport is required to access the database.
In client/server mode, the client application dispatches JDBC requests to
the JDBC server over a network; the server, in turn, which runs in the same
JVM as , sends requests
to through the embedded
JDBC driver.
SQLState XJZZZmeaning ofThe JDBC implementation provides
access to databases
and supplies all the required JDBC interfaces. Unimplemented aspects of the
JDBC driver return an SQLException with a message stating "Feature
not implemented" and an SQLState of XJZZZ. These unimplemented parts
are for features not supported by .
