Subject [jira] Updated: (DERBY-4015) Regression in Statement.getGeneratedKeys()
Date Sat, 10 Jan 2009 00:05:59 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4015?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Brandon Smith updated DERBY-4015:
---------------------------------

    Attachment: Behavior-Matrix.jpg

Consider the attached screenshot illustrating a behavior matrix between client and embedded,
versions 10.3.2.1 and 10.3.3.0, and four test cases. 

The test cases each call Connection.prepareStatement(String, String[]) with different values.

emptyArray == new String[] { }
fakeColumn == new String[] { "value" } where value is not a column
nullArray == new String[] { null }
nullParam == null

The matrix then records how each behaves and illustrates how the behavior changes not only
across versions, but also between client and embedded implementations.

>          Components: Network Client
>    Affects Versions: 10.3.3.0
>         Environment: I am currently running on Mac 10.5 with Java 5. However, it has
also been observed on other platforms in our automated build such as SUSE Linux and Windows
with Java 5.

> The application of both DERBY-2653 and DERBY-3426 in the 10.3.3.0 seems to have created
a regression in how the network JDBC client implementation of PreparedStatement.getGeneratedKeys()
behaves as compared to 10.3.2.1. Note that there wasn't a change in behavior between versions
for the embedded implementation. However, in general there are behavior discrepancies between
the network and client implementations for this method.
