## 删除测试表
DROP TABLE IF EXISTS tb2001;
DROP TABLE IF EXISTS tb2002;
DROP TABLE IF EXISTS tb2003;

## 创建测试表
CREATE TABLE tb2001(
id INT AUTO_INCREMENT PRIMARY KEY,
c1 VARCHAR(100) COLLATE utf8mb4_unicode_ci,
c2 VARCHAR(100) COLLATE utf8mb4_bin
)ENGINE=INNODB DEFAULT CHARSET=utf8mb4 ;

CREATE TABLE tb2002(
id INT AUTO_INCREMENT PRIMARY KEY,
c1 VARCHAR(100) COLLATE utf8mb4_general_ci,
c2 VARCHAR(100) COLLATE utf8mb4_bin
)ENGINE=INNODB DEFAULT CHARSET=utf8mb4;

CREATE TABLE tb2003(
id INT AUTO_INCREMENT PRIMARY KEY,
c1 VARCHAR(100) COLLATE utf8mb4_0900_ai_ci,
c2 VARCHAR(100) COLLATE utf8mb4_bin
)ENGINE=INNODB DEFAULT CHARSET=utf8mb4;

## 插入测试数据
INSERT INTO tb2001(c1,c2)VALUES(0xF09F8D83,0xF09F8D83),(0xF09FA68A,0xF09FA68A),(0xF09F8CA0,0xF09F8CA0);
INSERT INTO tb2002(c1,c2)VALUES(0xF09F8D83,0xF09F8D83),(0xF09FA68A,0xF09FA68A),(0xF09F8CA0,0xF09F8CA0);
INSERT INTO tb2003(c1,c2)VALUES(0xF09F8D83,0xF09F8D83),(0xF09FA68A,0xF09FA68A),(0xF09F8CA0,0xF09F8CA0);

## 等值查询测试
SELECT * FROM tb2001 WHERE c1=0xF09F8D83;
SELECT * FROM tb2002 WHERE c1=0xF09F8D83;
SELECT * FROM tb2003 WHERE c1=0xF09F8D83;

SELECT * FROM tb2001 WHERE c2=0xF09F8D83;
SELECT * FROM tb2002 WHERE c2=0xF09F8D83;
SELECT * FROM tb2003 WHERE c2=0xF09F8D83;
