Rick Hillegas reassigned DERBY-6931:
------------------------------------
Assignee: Himasha De Silva
> ClientPreparedStatement doesn't support executeLargeBatch
> ---------------------------------------------------------
>
> Key: DERBY-6931
> URL: https://issues.apache.org/jira/browse/DERBY-6931
> Project: Derby
> Issue Type: Bug
> Components: JDBC, Network Client
> Affects Versions: 10.11.1.1, 10.12.1.1, 10.13.1.1
> Reporter: Mark Swatosh
> Assignee: Himasha De Silva
> Attachments: Main.java
>
>
> When trying to run executeLargeBatch on a PreparedStatement, the following
> error is seen:
> Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object;
> cannot be cast to java.lang.String
> at
> org.apache.derby.client.am.ClientStatement.flowExecuteBatch(ClientStatement.java:2460)
> at
> org.apache.derby.client.am.ClientStatement.executeBatchX(ClientStatement.java:1292)
> at
> org.apache.derby.client.am.ClientStatement.executeLargeBatch(ClientStatement.java:1269)
> at com.test.Main.main(Main.java:22)
> Upon further inspection, I found executeLargeBatch isn't implemented in
> ClientPreparedStatement and it is using ClientStatement instead. It pulls in
> the parameter for the PreparedStatement as a Statement, which is where the
> ClassCastException occurs. I will attach a simple reproduction.
