Would you mind letting me have this defect? > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
