配置环境变量
对于mac 以及linux 添加path 变量

使用

init

dolt init

参考提示添加配置git

 
         Could not determine user.name. Use the init parameter --name "FIRST LAST" to set it for this repo, or dolt config --global --add user.name "FIRST LAST" 
        
         usage: dolt init [<options>] [<path>] 
        
         ​ 
        
         Specific dolt init options 
        
             --name=<name> 
        
               The name used in commits to this repo. If not provided will be taken 
        
               from "user.name" in the global config. 
        
         ​ 
        
             --email=<email> 
        
               The email address used. If not provided will be taken from 
        
               "user.email" in the global config.

 
         dolt config --global --add user.name "dalong" 
        
         dolt config --global --add user.email "1141591465@qq.com"

从新运行效果github

 
         dolt init  
        
         Successfully initialized dolt data repository.

目录结构golang

 
         tree .dolt

         1 directory, 8 files

添加sql支持

 
         dolt sql -q "create table state_populations ( state varchar, population int, primary key (state) )" 
        
         dolt sql -q "show tables"

效果sql

 
         +-------------------+ 
        
         | tables | 
        
         +-------------------+ 
        
         | state_populations | 
        
         +-------------------+

插入数据

 
         dolt sql -q 'insert into state_populations (state, population) values 
        
         ("Delaware", 59096), 
        
         ("Maryland", 319728), 
        
         ("Tennessee", 35691), 
        
         ("Virginia", 691937), 
        
         ("Connecticut", 237946), 
        
         ("Massachusetts", 378787), 
        
         ("South Carolina", 249073), 
        
         ("New Hampshire", 141885), 
        
         ("Vermont", 85425), 
        
         ("Georgia", 82548), 
        
         ("Pennsylvania", 434373), 
        
         ("Kentucky", 73677), 
        
         ("New York", 340120), 
        
         ("New Jersey", 184139), 
        
         ("North Carolina", 393751), 
        
         ("Maine", 96540), 
        
         ("Rhode Island", 68825)'

查询

 
         dolt sql -q "select * from state_populations where state = 'New York'" 
        

效果json

 
         +----------+------------+ 
        
         | state | population | 
        
         +----------+------------+ 
        
         | New York | 340120 | 
        
         +----------+------------+

git 方式提交操做

 
         ➜ first dolt add . 
        
         ➜ first dolt commit -m "init demo" 
        
         commit 1j1o30pvevn6ldbpg2jeu43i7uu6b3pj 
        
         Author: dalong <1141591465@qq.com> 
        
         Date: Sun Oct 27 11:06:57 +0800 2019 
        
          init demo 
        
         ➜ first dolt status 
        
         On branch master 
        
         nothing to commit, working tree clean

说明

以上是一个简单的操做，实际上dolt 支持了方便的数据导入，数据更新功能，功能操做和git 一直，源码基于golang 编写，能够学习下源码ide
