SQLite3 是一个轻量级的数据库管理系统，它包含在一个C库中，无需服务器进程即可运行。SQLite3被设计用于嵌入式系统和应用程序，因其零配置、高可靠性以及占用资源少的特性而广受欢迎

steps

1.下载
https://www.sqlite.org/download.html

2.安装
# bin文件安装
解压下载的文件，放到/usr/bin/

# rpm文件安装
yum install -y sqlite   sqlite-devel

3.运行
sqlite3

4.测试基本命令
sqlite3   test.db   //创建数据库
create table mytable(id integer primary key, value text);
insert into mytable(id, value) values(1, 'Micheal');
select * from mytable;

# 设置格式化查询结果
sqlite> .mode column;
sqlite> .header on;
sqlite> select * from test;
id     value
----------- -------------
1      Micheal
2      Jenny
3      Francis
4      Kerk
.mode column 将设置为列显示模式
.header on 将显示列名

# 修改表结构，增加列：
sqlite> alter table mytable add column email text not null '' collate nocase;;

# 创建视图：
sqlite> create view nameview as select * from mytable;

# 创建索引：
sqlite> create index test_idx on mytable(value);

显示表结构：
sqlite> .schema [table]
获取所有表和视图：
sqlite > .tables
获取指定表的索引列表：
sqlite > .indices [table ]
导出数据库到 SQL 文件：
sqlite > .output [filename ]
sqlite > .dump
sqlite > .output stdout
从 SQL 文件导入数据库：
sqlite > .read [filename ]
格式化输出数据到 CSV 格式：
sqlite >.output [filename.csv ]
sqlite >.separator ,
sqlite > select * from test;
sqlite >.output stdout
从 CSV 文件导入数据到表中：
sqlite >create table newtable ( id integer primary key, value text );
sqlite >.import [filename.csv ] newtable
备份数据库：
/* usage: sqlite3 [database] .dump > [filename] */
sqlite3 mytable.db .dump > backup.sql
恢复数据库：
/* usage: sqlite3 [database ] < [filename ] */
sqlite3 mytable.db < backup.sql
