Subject [jira] [Updated] (DERBY-6000) Implement support for JDBC 4.2
Date Thu, 07 Feb 2013 18:59:13 GMT

     [ https://issues.apache.org/jira/browse/DERBY-6000?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Rick Hillegas updated DERBY-6000:

    Attachment: derby-6000-09-ac-setObjectPS.diff

Attaching derby-6000-09-ac-setObjectPS.diff. This patch adds support for the new PreparedStatement.setObject()
overloads added by JDBC 4.2. I am running tests now.

Adds the following methods to the embedded and client drivers:

  PreparedStatement.setObject(int parameterIndex, java.lang.Object x, SQLType targetSqlType)
  PreparedStatement.setObject(int parameterIndex, java.lang.Object x, SQLType targetSqlType,
int scaleOrLength)

The new overloads implement the following logic:

a) Raise an exception if SQLType is not a JDBCType whose corresponding type in java.sql.Types
is supported by Derby.

b) Otherwise forward the call to the corresponding setObject() overload, using the corresponding
type from java.sql.Types.

This patch adds a new JDBC 4.2 module to the engine. Additional JDBC 4.2 work can expand this
module. Some temporary build logic has been added to allow the build to succeed if you are
building with a version of Java before version 8. We can remove this temporary logic once
Java 8 goes live and we can create JDBC 4.2 stubs parallel to the stubs for previous JDBC

Touches the following files:

Build logic.

Removed an unneeded exception declaration from a HarmonySerialBlob constructor.

JDBC 4.2 adds a new type id: REF_CURSOR.

New JDBC 4.2 engine module.

The tests for this patch tripped over an existing bug in the client driver: PreparedStatement.setObject(
int, Object, int ) fails if you are trying to set a UDT. The simpler overload of this method
(setObject( int, Object )) was tested and worked. I have added a little logic to make the
failing overload work in this case. The overload which used to fail is tested by the new tests
added for this feature.

> Open JDK 8 will include maintenance rev 4.2 of JDBC. The public discussion of JDBC 4.2
will take place here: http://openjdk.java.net/jeps/170. We will want to build Derby support
for JDBC 4.2 after a public spec appears. At this time, it is unclear what Derby release will
carry this support.
