MySQL 용어  Mongo 용어 
database database 
 table collection 
 index  index
 row  BSON document
 column  BSON field
 join  embedding and linking


 

 SQL 문장 Mongo 쿼리 문장 
CREATE TALE USERS (a int, b int) db.createCollection("mycoll") 
 INSERT INTO USERS VALUES (3,5) db.users.insert({a:3, b:5}) 
 SELECT a, b FROM USERS db.users.find({}, {a:1, b:1}) 
 SELECT * FROM users  db.users.find()
 SELECT * FROM users WHERE age=33  db.users.find({age:33})
 SELECT a,b FROM users WHERE age=33  db.users.find({age:33}, {a:1,b:1})
 SELECT * FROM users WHERE age=33 ORDER BY name  db.users.find({age:33}).sort({name:1})
