Concrete classes in the oracle.sql package

The concrete classes in the oracle.sql package are deprecated. Use the new JDBC interfaces instead of these classes.

defineColumnType method

Most of the variants of the defineColumnType method are deprecated. The supported variants are for:
- LOB to LONG conversions
- Configure the LOB prefetch size
See the JDBC Javadoc for more information.
CONNECTION_PROPERTY_STREAM_CHUNK_SIZE property

See the JDBC Javadoc for more information.
Oracle Update Batching

Oracle update batching was deprecated in Oracle Database 12c Release 1 (12.1). Since Oracle Database 12c Release 2 (12.2), Oracle update batching is a no operation code (no-op). This means that if you implement Oracle update batching in your application, using the Oracle Database 19c JDBC driver, then the specified batch size is not set and results in a batch size of 1. With this batch setting, your application processes one row at a time. Oracle strongly recommends that you use the standard JDBC batching if you are using the Oracle Database 19c JDBC driver.

See Standard Update Batching section for more information.
EndToEndMetrics related APIs

EndToEndMetrics related APIs are deprecated since Oracle Database 12c release 2 (12.2).

See JDBC DMS Metrics for more information.
