测试试用下
官方文档从这一章节开始看
官方文档入口
先下载官方提供的测试数据
https://raw.githubusercontent.com/mongodb/docs-assets/primer-dataset/primer-dataset.json
大约12M
导入测试数据
mongoimport --db test --collection restaurants --drop --file ~/primer-dataset.json
我是下载在root下了 所以直接 ~/
命令测试
官方文档连接
直接输入命令 mongo 开始
mongo
输入help查看帮助
db.help() help on db methods
db.mycoll.help() help on collection methods
sh.help() sharding helpers
rs.help() replica set helpers
help admin administrative help
help connect connecting to a db help
help keys key shortcuts
help misc misc things to know
help mr mapreduce
show dbs show database names
show collections show collections in current database
show users show users in current database
show profile show most recent system.profile entries with time >= 1ms
show logs show the accessible logger names
show log [name] prints out the last segment of log in memory, 'global' is default
use <db_name> set current database
db.foo.find() list objects in collection foo
db.foo.find( { a : 1 } ) list objects in foo where a == 1
it result of the last line evaluated; use to further iterate
DBQuery.shellBatchSize = x set default number of items to display on shell
exit quit the mongo shell
测试下上面的命令
查看数据库
show dbs
admin 0.000GB
local 0.000GB
test 0.005GB
这里有了一个 test 数据库,就是刚刚导入的测试数据库,默认是只有admin 和 local的
选择数据库
use test
我们测试的test
查看collections
show collections
restaurants
刚刚导入的restaurants collections
各种查询命令
大体结构是
db.CollectionName.find({ <field1>: <value1>, <field2>: <value2>, … })
官方详解
自查
插入数据
db.Students.insert({"name":"sam","age":15,"sex":"m"})
db.Students.find()
退出命令
exit
