db.students.insert({first_name:'AA',last_name:'BB',cours_reussis:[{intitule:'PAI',note:0,name_school:'EPFC']}) I would like to update a field only. name_school : "ENSA" instead of " EPFC" thank you soo much I would like to update a field in an array of embedded documents.

My sample document is:

db.students.insert(
    {
        first_name:'AA',
        last_name:'BB',
        cours_reussis:[{intitule:'PAI',note:0,name_school:'EPFC'}]
    }
)

I'd like to change the value of name_school to "ENSA" instead of "EPFC".
