Subject [jira] Issue Comment Edited: (JCR-2765) JCR-SQL2 : no count when WHERE clause is provided

This is not a blocker - maybe for your requirements, but not for Jackrabbit. A blocker would
be that jackrabbit does not start, no nodes/properties could be read etc.

Since getSize() can return -1 by definition (and the order by trick to force getSize() have
the hit count returned is just a "trick"), this is actually an improvement. Manually counting
through the iterator is the way to go without the trick.

> whenever you provide a where-clause to a sql2 select, jcr/jackrabbit does not provide
the hit count.
> E.g.:
>    select * from [nt:unstructured]
>    order by [jcr:score]
> returns the hit count (query.execute().getRows().getSize()), 
> whereas
>   select * from [nt:unstructured]
>   where entity = "customer"
>   order by [jcr:score]
> doesn't.
