Here are some other counting implementation that I have gleaned from the list. Perhaps they are of interest?

Perhaps... or perhaps you could use the hidden power of raw <gasp>JDBC</gasp> instead:

public class EFCount extends EFSelect
{

// ======================================================================== === // Constant(s) // ------------------------------------------------------------------------ ---

        private static final String             Count = "COUNT(*)";

// ======================================================================== === // Class variable(s) // ------------------------------------------------------------------------ ---

// ======================================================================== === // Instance variable(s) // ------------------------------------------------------------------------ ---

// ======================================================================== === // Constructor method(s) // ------------------------------------------------------------------------ ---

public EFCount(final DataSource aDataSource, final Class anEntity, final SZQualifier aQualifier) { super( aDataSource, anEntity, aQualifier, null ); }

// ======================================================================== === // Class method(s) // ------------------------------------------------------------------------ ---

// ======================================================================== === // Instance method(s) // ------------------------------------------------------------------------ ---

// ======================================================================== === // EFAction method(s) // ------------------------------------------------------------------------ ---

        protected String attributesDescription()
        {
                return EFCount.Count;
        }

        public int count() throws SQLException
        {
                Iterator        anIterator = this.execute();
                int             aCount = 0;

if ( anIterator.hasNext() == true ) { Map someValues = (Map) anIterator.next(); Number aNumber = (Number) someValues.values().iterator().next();

                        if ( aNumber.intValue() > 0 )
                        {
                                aCount = aNumber.intValue();
                        }
                }

                this.close();

                return aCount;
        }


Cheers
