How to convert SQL query to MongoDB

Question

SELECT s_name FROM supplier 
WHERE s_suppkey = ALL
(SELECT s_suppkey FROM supplier
WHERE s_nationkey > 50 AND s_acctbal= 9658.99 )

I don't know how to do this part

WHERE s_suppkey = ALL
    (SELECT s_suppkey FROM supplier
    WHERE s_nationkey > 50 AND s_acctbal= 9658.99 )

Answer 1

db.supplier.find( {}, { $and : [  {  s_nationkey : { '$gt' : 50 } }, { s_acctbal : 9658.99 } ] } ,{s_suppkey:1} )

But does not return suppliers name!

Answer 2

You SQL looks a bit strange. For Mongo try this one:

db.supplier.find({ s_nationkey: { '$gt': 50 }, s_acctbal: 9658.99 }, {s_name :1} )
