Subject [jira] [Updated] (DERBY-5488) Add remaining JDBC 4.1 bits which did not appear in the Java 7 javadoc.
Date Wed, 02 Nov 2011 20:43:32 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5488?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Rick Hillegas updated DERBY-5488:

    Attachment: derby-5488-02-aa-fixBigInteger.diff

Attaching derby-5488-02-aa-fixBigInteger.diff. This patch corrects the behavior of setObject(
int, BigInteger ). I will run tests.

The overflow/underflow/truncation behavior of setObject() is not clearly documented by the
JDBC spec. Lance Andersen thinks that this might be addressed in JDBC 4.2, the next rev of
the spec which will accompany Java 8.

In the meantime, I have let the following principles guide the revised implementation of setObject(
int, BigInteger ):

1) Overflow/underflow/truncation should behave as it does for other numeric objects.

2) BigInteger should not be less capable than the corresponding BigDecimal for the same integer

Touches the following files:


M       java/engine/org/apache/derby/impl/jdbc/EmbedPreparedStatement20.java
M       java/engine/org/apache/derby/impl/jdbc/EmbedPreparedStatement.java

Fix for embedded JDBC driver.


M       java/client/org/apache/derby/client/am/CrossConverters.java
M       java/client/org/apache/derby/client/am/PreparedStatement.java

Fix for network JDBC driver.


M       java/testing/org/apache/derbyTesting/functionTests/tests/jdbcapi/ParameterMappingTest.java

Additional test case to verify overflow/underflow/truncation behavior.

> In addition to the JDBC 4.1 bits which were visible in the Java 7 javadoc, a couple other
items appear in the JDBC 4.1 Maintenance Review spec. This spec has been published on the
JCP website at http://download.oracle.com/otndocs/jcp/jdbc-4_1-mrel-eval-spec/index.html.
I will attach a functional spec for the remaining bits.
