Subject [jira] [Created] (DERBY-5614) NullPointerException with INSERT INTO [global temporary table] SELECT ... FROM [VTI]
Date Tue, 14 Feb 2012 14:44:00 GMT
NullPointerException with INSERT INTO [global temporary table] SELECT ... FROM [VTI]
------------------------------------------------------------------------------------

                 Key: DERBY-5614
                 URL: https://issues.apache.org/jira/browse/DERBY-5614
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.9.0.0
            Reporter: Kristian Waagan
            Assignee: Kristian Waagan


Inserting into a global temporary table (GTT) while selecting data from a VTI fails with a
NullPointerException:

Caused by: java.lang.NullPointerException
        at org.apache.derby.impl.sql.execute.WriteCursorConstantAction.getEmptyHeapRow(WriteCursorConstantAction.java:324)
        at org.apache.derby.impl.sql.execute.InsertResultSet.bulkInsertCore(InsertResultSet.java:1209)
        at org.apache.derby.impl.sql.execute.InsertResultSet.open(InsertResultSet.java:466)
        at org.apache.derby.impl.sql.GenericPreparedStatement.executeStmt(GenericPreparedStatement.java:443)
        at org.apache.derby.impl.sql.GenericPreparedStatement.execute(GenericPreparedStatement.java:324)
        at org.apache.derby.impl.jdbc.EmbedStatement.executeStatement(EmbedStatement.java:1242)
        ... 6 more

Investigation exposed the fact that bulk insert doesn't support a GTT as the target, and further
that Derby enables bulk insert when the source is a VTI.
