Mark Swatosh created DERBY-6931: ----------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
