mysql查看数据库是不是utf8_general_ci

要查看MySQL数据库的字符编码和排序规则,可以使用以下命令:
```
SHOW CREATE DATABASE dbName;
```
其中,dbName是你想查看的数据库名称。这个命令将返回一个类似于以下内容的结果:
```
CREATE DATABASE `dbName` /*!40100 DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci */
```
可以看到,在这个结果中,字符编码被设置为UTF-8,排序规则被设置为utf8_general_ci。如果结果中没有明确指定字符编码和排序规则,则表示使用的是MySQL的默认编码和排序规则。

mysql创建数据库utf8_general_ci
要创建一个使用UTF-8字符编码的MySQL数据库,可以使用以下命令:
```
CREATE DATABASE dbName CHARACTER SET utf8 COLLATE utf8_general_ci;
```
其中,dbName是你想创建的数据库名称。这个命令将创建一个名为dbName的数据库,并将其字符编码设置为UTF-8,排序规则设置为utf8_general_ci。
根据以下给的数据库表结构,用PyQt5+MySQL实现增删改查,表结构如下:CREATE TABLE `register_copy1` ( `id` int NOT NULL AUTO_INCREMENT, `register_type` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `tooth_number` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `hospital_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `doctor_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `patient_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `color_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `category_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `price` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `tooth_a` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `tooth_b` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `tooth_c` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `tooth_d` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `number` int NOT NULL, `amount_of_money` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `delivery_date` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `register_date` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `remark` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `total_amount` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, PRIMARY KEY (`id`) USING BTREE ) ENGINE = InnoDB AUTO_INCREMENT = 48 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic; SET FOREIGN_KEY_CHECKS = 1;
我可以回答这个问题。要实现增删改查,需要使用PyQt5和MySQL。首先,需要连接到MySQL数据库,然后创建一个表格模型,并将其与表格视图关联。接下来,可以使用模型的方法来添加、删除和修改数据。查询数据可以使用SQL语句来执行。具体实现细节可以参考PyQt5和MySQL的文档。
