Knut Anders Hatlen commented on DERBY-4585: ------------------------------------------- Hi Martin, Could you please also post the DDL statements used to create the tables involved in the query (including any tables with foreign key constraints referencing LCAPPCHILDCONTROLTITLE)? When you say that the database seems to be corrupt, which symptoms do you see? Do you also see those problems after rebooting the database? > IndexChanger.doDelete throws NullPointerException > ------------------------------------------------- > > Key: DERBY-4585 > URL: https://issues.apache.org/jira/browse/DERBY-4585 > Project: Derby > Issue Type: Bug > Affects Versions: 10.5.3.0 > Environment: Various operating systems, Java 1.6.0_18 > Reporter: Martin Keller > > After a bunch of DELETE and DROP-Commands, the following error occurs in our > application: > 2010-03-16 12:54:23.070 GMT Thread[DRDAConnThread_4,5,derby.daemons] (XID = > 15898), (SESSIONID = 1), (DATABASE = ixintrexx), (DRDAID = > NF000001.PAA8-4469821361421447518{2}), Cleanup action starting > 2010-03-16 12:54:23.070 GMT Thread[DRDAConnThread_4,5,derby.daemons] (XID = > 15898), (SESSIONID = 1), (DATABASE = ixintrexx), (DRDAID = > NF000001.PAA8-4469821361421447518{2}), Failed Statement is: DELETE FROM > LCAPPCHILDCONTROLTITLE WHERE STRCHILDCONTROLGUID IN (SELECT STRGUID FROM > LCAPPCHILDCONTROL WHERE STRAPPCONTROLDRGUID IN (SELECT A.STRGUID FROM > LCAPPCONTROLDR A, LCAPPFUP B WHERE A.STRAPPFUPGUID = B.STRGUID AND > B.STRAPPGUID = '93A720B90BB6C25703701E67D0DA75220B7D2FFC')) > java.lang.NullPointerException > at > org.apache.derby.impl.sql.execute.IndexChanger.doDelete(IndexChanger.java:369) > at > org.apache.derby.impl.sql.execute.IndexChanger.delete(IndexChanger.java:544) > at > org.apache.derby.impl.sql.execute.IndexSetChanger.delete(IndexSetChanger.java:250) > at > org.apache.derby.impl.sql.execute.RowChangerImpl.deleteRow(RowChangerImpl.java:476) > at > org.apache.derby.impl.sql.execute.DeleteResultSet.collectAffectedRows(DeleteResultSet.java:405) > at > org.apache.derby.impl.sql.execute.DeleteResultSet.open(DeleteResultSet.java:137) > at > org.apache.derby.impl.sql.GenericPreparedStatement.executeStmt(GenericPreparedStatement.java:416) > at > org.apache.derby.impl.sql.GenericPreparedStatement.execute(GenericPreparedStatement.java:297) > at > org.apache.derby.impl.jdbc.EmbedStatement.executeStatement(EmbedStatement.java:1235) > at > org.apache.derby.impl.jdbc.EmbedStatement.execute(EmbedStatement.java:625) > at > org.apache.derby.impl.jdbc.EmbedStatement.executeUpdate(EmbedStatement.java:175) > at > org.apache.derby.impl.drda.DRDAConnThread.parseEXCSQLIMM(DRDAConnThread.java:5022) > at > org.apache.derby.impl.drda.DRDAConnThread.processCommands(DRDAConnThread.java:750) > at > org.apache.derby.impl.drda.DRDAConnThread.run(DRDAConnThread.java:290) > Cleanup action completed > The database seems to be corrupt, after this exception has been thrown. > As you can see, I already compiled Derby to get the line number where the > error occurs.
