MySQL从小白到总裁完整教程目录:https://blog.csdn.net/weixin_67859959/article/details/129334507?spm=1001.2014.3001.5502

语法格式:

show create database 数据库名称;

案列:查看testing数据库信息

mysql> show create database testing;
+----------+-----------------------------------------------------------------+
| Database | Create Database                                                 |
+----------+-----------------------------------------------------------------+
| testing  | CREATE DATABASE `testing` /*!40100 DEFAULT CHARACTER SET gbk */ |
+----------+-----------------------------------------------------------------+
1 row in set (0.00 sec)

练习:查看当前有多少个数据库

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| bd_ecshop          |
| mysql              |
| performance_schema |
| test               |
| testing            |
+--------------------+
6 rows in set (0.01 sec)

 一共有六个数据库

查看一下数据库名称为MySQL的数据库的字符集是什么

mysql> show create database mysql;
+----------+------------------------------------------------------------------+
| Database | Create Database                                                  |
+----------+------------------------------------------------------------------+
| mysql    | CREATE DATABASE `mysql` /*!40100 DEFAULT CHARACTER SET latin1 */ |
+----------+------------------------------------------------------------------+
1 row in set (0.00 sec)

字符集是Latin1

比如说我把数据库名写错,它会怎么显示

mysql> show create database mysql222;
ERROR 1049 (42000): Unknown database 'mysql222'

练习:创建一个数据库名称为czwbkl,字符集为utf8                数据库的全名是橙子味冰可乐的缩写,以后经常会用到,哈哈哈

mysql> create database czwbkl charset utf8;
Query OK, 1 row affected (0.00 sec)

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| bd_ecshop          |
| czwbkl             |
| mysql              |
| performance_schema |
| test               |
| testing            |
+--------------------+
7 rows in set (0.00 sec)

mysql> show create database czwbkl;
+----------+-----------------------------------------------------------------+
| Database | Create Database                                                 |
+----------+-----------------------------------------------------------------+
| czwbkl   | CREATE DATABASE `czwbkl` /*!40100 DEFAULT CHARACTER SET utf8 */ |
+----------+-----------------------------------------------------------------+
1 row in set (0.00 sec)
