Is it possible to use function in MongoDB $where clause?

Question

I need to find out that if it is possible to use function in $where clause string like this:

db.myCollection.find( "this.name == 'xyz' || function() {return 1>0;} || this.name == 'abc'" );

Thanks in advance.

Answer 1

I'm not quite sure what you're trying to do, but put all your checks in a single function that's the value of the $where :

db.myCollection.find({$where: function() {
    return this.name == 'xyz' || 1>0 || this.name == 'abc';
}});

Answer 2

It is possible to use nested functions within functions in JS but there are some considerations as this question will tell you: JavaScript Nested function

However, as @JohnnyHK said, this isn't really a good way of doing a $where , if there is at all.
