-----------------------------------
Summary: 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: 10.12.1.1, 10.11.1.1, 10.13.1.1
Reporter: Mark Swatosh
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.
