[ https://issues.apache.org/jira/browse/DERBY-6931?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16178715#comment-16178715 ] Himasha De Silva commented on DERBY-6931: - The flowExecuteBatch() method in ClientStatement calls the parseSqlAndSetSqlModes(sql) method. For the sql parameter i passed a string "" then i get an exception. Can i know what type of String is expected for the sql parameter? Does it have a specific format? > 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.
