mongodb与mysql命令对比
传统的关系数据库一般由数据库(database)、表(table)、记录(record)三个层次概念组成,MongoDB是由数据库(database)、集合(collection)、文档对象(document)三个层次组成。MongoDB对于关系型数据库里的表,但是集合中没有列、行和关系概念,这体现了模式自由的特点。

Db.addUser() Db.auth() | 新建用户并权限 |
show databases | show dbs | 显示库列表 |
Show tables | Show collections | 显示表列表 |
Show slave status | Rs.status | 查询主从状态 |
Create table users(a int, b int) |
db.createCollection("mycoll", {capped:true, size:100000}) 另:可隐式创建表。 | 创建表 |
Create INDEX idxname ON users(name) | db.users.ensureIndex({name:1}) | 创建索引 |
Create INDEX idxname ON users(name,ts DESC) | db.users.ensureIndex({name:1,ts:-1}) | 创建索引 |
Insert into users values(1, 1) | db.users.insert({a:1, b:1}) | 插入记录 |
Select a, b from users | db.users.find({},{a:1, b:1}) | 查询表 |
Select * from users | db.users.find() | 查询表 |
Select * from users where age=33 | db.users.find({age:33}) | 条件查询 |
Select a, b from users where age=33 | db.users.find({age:33},{a:1, b:1}) | 条件查询 |
select * from users where age | db.users.find({'age':{$lt:33}}) | 条件查询 |
select * from users where age>33 and age | db.users.find({'age':{$gt:33,$lte:40}}) | 条件查询 |
select * from users where a=1 and b='q' | db.users.find({a:1,b:'q'}) | 条件查询 |
select * from users where a=1 or b=2 | db.users.find( { $or : [ { a : 1 } , { b : 2 } ] } ) | 条件查询 |
select * from users limit 1 | db.users.findOne() | 条件查询 |
select * from users where name like "%Joe%" | db.users.find({name:/Joe |
