Description

When using org.apache.cassandra.cql.jdbc.CResultSet getColumn to retrieve col data you will always be missing the first one.

ex: SELECT name, pwd from user;
returns only pwd.

The issue is at http://code.google.com/a/apache-extras.org/p/cassandra-jdbc/source/browse/src/org/apache/cassandra/cql/jdbc/CResultSet.java#348

The call to checkIndex passes, but the values.get(index) call causes the lookup to go over the ArrayList size.

This needs to be changed to:

values.get(index - 1)
