It's hard to know what your question means as it involves syntax that
isn't Xquery and so its hard to say how to convert it to xquery without
some description in text as to what you wish to calculate.


> Let &j= <bookstore>

I assume this is intended to be
let $j := <bookstore>
^   ^
    
> let $whrcnd = Book/author/lastname= bob and
> book/price=55

I assume that that is intended to be

let $whrcnd := book/author/lastname= "bob" and book/price=55
            ^  ^                     ^   ^

> I need to select count(*) from $j where $whrcnd
> Group by <records of book>

Sorry, I couldn't guess what this was intended to do.


> The result is 2

count($j/book[author/lastname= "bob" and price=55])

is 2 but I'm not sure if that's the query that you need.
