Internals

What’s inside

Please take notice of the corresponding implementation notes:

• CallableStatement is not supported, as CrateDB itself does not support stored procedures.

• DataSource is not supported.

• ParameterMetaData, e.g. as returned by PreparedStatement, is not supported.

• ResultSet objects are read only (TYPE_FORWARD_ONLY, CONCUR_READ_ONLY), so changes to a ResultSet are not supported.

• DDL and DML statements are supported through adjustments to the PgPreparedStatement and PgStatement interfaces.

To learn further details about the compatibility with JDBC and PostgreSQL features, see the specific code changes to the PgConnection, PgDatabaseMetaData, and PgResultSet classes.
