> I am preparing and executing an SQL2 query (JCR 2.0) as follows:
> QueryManager qm = jcrSession.getWorkspace().getQueryManager();
> String queryString = "select order.[customerAccountUUID] as cust from [atl:order] as
order";
> Query query = qm.createQuery(queryString, Query.JCR_SQL2);
> QueryResult queryResult = query.execute();
> The following query fails:
> select order.[customerAccountUUID] from [atl:order] as order
> java.lang.NullPointerException
>         org.apache.jackrabbit.commons.query.sql2.QOMFormatter.isSimpleName(QOMFormatter.java:577)
>         org.apache.jackrabbit.commons.query.sql2.QOMFormatter.formatName(QOMFormatter.java:567)
>         org.apache.jackrabbit.commons.query.sql2.QOMFormatter.format(QOMFormatter.java:452)
>         org.apache.jackrabbit.commons.query.sql2.QOMFormatter.format(QOMFormatter.java:123)
>         org.apache.jackrabbit.commons.query.sql2.QOMFormatter.format(QOMFormatter.java:117)
> line 452: c.getColumnName() returns null.
> The following query is fine:
> select order.[customerAccountUUID] as cust from [atl:order] as order
> I have been using the test case (here: http://svn.apache.org/viewvc/jackrabbit/trunk/jackrabbit-spi-commons/src/test/resources/org/apache/jackrabbit/spi/commons/query/sql2/test.sql2.txt?view=markup)
as a guideline.
> Cheers,
