[jira] Updated: (DERBY-4315) Attempt to reuse streams in client on
insert gives protocol exception and inserts wrong data
[ https://issues.apache.org/jira/browse/DERBY-4315?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rick Hillegas updated DERBY-4315:
---------------------------------
Attachment: ReproReuseStream.java
Attaching a revised version of the repro. This version runs the test on both the embedded and client/server drivers. To run this version, you need to specify the port which the server is listening on:
java ReproReuseStream 8246

Drop exception ok:'DROP TABLE' cannot be performed on 'TEST' because it does not exist.

> URL: https://issues.apache.org/jira/browse/DERBY-4315
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.1.3.1, 10.2.2.0, 10.3.3.0, 10.4.2.0, 10.5.1.1, 10.5.2.0, 10.6.1.0
> Reporter: Kathey Marsden
> Attachments: ReproReuseStream.java, ReproReuseStream.java

>
> If a user attempts to reuse a stream set as a parameter to a prepared statement, the statement execution should fail with SQL State XJ001. Instead client fails with a protocol error and inserts wrong data. See the attached java program ReproReuseStream.java for a reproduction.
