This quite obviously is a bug in SQL::Statement, as when I display the requireed parameters (r) and the parameters actually passed (p), I see this:

{   p                => [
        [
            [   'number',
                'name',
                'sex',
                'age'
                ],
            [   0,
                'Jack',
                'M',
                28
                ],
            [   1,
                'Marry',
                'F',
                29
                ]
            ]
        ],
    r                => [
        bless ({
            num              => 0
            }, 'SQL::Statement::Param' )
        ]
    }

You could disable the complete parameter count match test if the required params is a blessed SQL::Statement::Param object, but I'm afraid that is sweeping problems under the carpet.

Update: the this statement passed by accident before my fix, as the required list of parameters consisted of only one (wrong) item: an unchecked blessed object. The number of items in the parameters passed was also just one single item: a list reference. The old test just check the lowest level where one happens to be one and the test passed.


Enjoy, Have FUN! H.Merijn
