mysql的粗略学习

输入root进入mysql

试着输入了两个语法都没动静，输入\h终于有反应了

语法错误

show databases; //显示数据库

为什么没有人告诉我还有个英文下的分隔符号。。。

查的资料不是没有就是汉语的符号。。。

mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| my_db |
| mysql |
| performance_schema |
| shopdata |
| think |
| thinkphp |
| wenzhang |
+--------------------+
8 rows in set (0.05 sec)

炒大米。。。味道不错。。。

我想看看shopdata这个数据库里都有些什么表

Database changed
mysql> show tables;

126 rows in set (0.00 sec)

换一个

mysql> use thinkphp;
Database changed
mysql> show tables;
+--------------------+
| Tables_in_thinkphp |
+--------------------+
| think_data |
+--------------------+
1 row in set (0.00 sec)

mysql>

查看think_data表里有几个列，都是写什么

mysql> desc think_data;
+-------+-----------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+-----------------+------+-----+---------+----------------+
| id | int(8) unsigned | NO | PRI | NULL | auto_increment |
| data | varchar(255) | NO | | NULL | |
+-------+-----------------+------+-----+---------+----------------+
2 rows in set (0.01 sec)

mysql>

查看列中具体有哪些数据，语法从phpadmin里找到的。。。

mysql> SELECT * FROM `think_data`;
+----+-----------+
| id | data |
+----+-----------+
| 1 | thinkphp |
| 2 | php |
| 3 | framework |
+----+-----------+
3 rows in set (0.00 sec)

mysql>

大概就是这么个结构了。。。

如何建立一个utf8数据库？

mysql> CREATE DATABASE confluence CHARACTER SET utf8 COLLATE utf8_bin;
Query OK, 1 row affected (0.00 sec)

mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| confluence |
| my_db |
| mysql |
| performance_schema |
| shopdata |
| think |
| thinkphp |
| wenzhang |
+--------------------+
9 rows in set (0.00 sec)

百度一下

character

[英]ˈkærəktə(r)

[美]ˈkærəktɚ

n.	性格;特点;字母;角色

vt.

刻，印;使具有特征

collate

[英][kə'leɪt][美][kəˈlet, ˈkɑlˌet, ˈkoˌlet]

vt.核对，校对（书、底稿等）; （装钉）整理，检查; [宗]委任牧师职;

角色这个单词好像学过，校对就完全没有映像了。。。
