确定将MySQL DB的字符集设置为什么

假设我们正在创建数据库“ web”-

mysql> SHOW CREATE DATABASE web;

这将产生以下显示默认字符集的输出-

+----------+-----------------------------------------------------------------------------------------+
| Database | Create Database                                                                         |
+----------+-----------------------------------------------------------------------------------------+
| web      | CREATE DATABASE `web` /*!40100 DEFAULT CHARACTER SET utf8 COLLATEutf8_unicode_ci */     | 
+----------+-----------------------------------------------------------------------------------------+
1 row in set (0.03 sec)

如果您想从数据库中了解特定表的字符集，请使用以下查询。在这里，假设我们在数据库“ web”中有一个名为DemoTable的表-

mysql> SHOW CREATE table web.DemoTable;

这将产生以下显示字符集的输出-

+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| Table        | Create Table                                                                                                                     |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| DemoTable    | CREATE TABLE `DemoTable` (`Value` int(11) DEFAULT NULL) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci               |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
