Go语言之进阶篇 mysql操作基本语法

一、mysql操作基本语法

1、创建名称nulige的数据库 

CREATE DATABASE nulige DEFAULT CHARSET utf8 COLLATE utf8_general_ci; use nulige;　　

2、建表，Id自增

create table user_info(
  	nid int not null auto_increment primary key,
    username varchar(20), 
    departname varchar(20), 
    create_time timestamp default "0000-00-00 00:00:00"
);　

3、往表中插入数据

INSERT INTO user_info (username,departname,create_time) VALUES ("nulige","行政部","2019-1-13 12:23:00");
INSERT INTO user_info (username,departname,create_time) VALUES ("jojo","财务部","2019-1-14 1:23:00");
INSERT INTO user_info (username,departname,create_time) VALUES ("huhui","销售部","2019-1-15 2:23:00");

4、查询表中内容

mysql> select * from user_info;
+-----+----------+------------+---------------------+
| nid | username | departname | create_time         |
+-----+----------+------------+---------------------+
|   1 | nulige   | 行政部   | 2019-01-13 12:23:00 |
|   2 | jojo      | 财务部    | 2019-01-14 01:23:00 |
|   3 | huhui    | 销售部    | 2019-01-15 02:23:00 |
+-----+----------+------------+---------------------+
3 rows in set (0.00 sec)　

5、删除数据库

mysql> drop database nulige;
Query OK, 1 row affected (0.01 sec)

6、清空表中数据，保留表结构

mysql> delete from user_info;
Query OK, 5 rows affected (0.00 sec)
