以如下建表语句填充数据,不超过10create table db_test.tb_student( name string, score int, city string, sex string, hobby string )

insert into db_test.tb_student values ('Alice', 90, 'Shanghai', 'female', 'reading');
insert into db_test.tb_student values ('Bob', 80, 'Beijing', 'male', 'swimming');
insert into db_test.tb_student values ('Cathy', 85, 'Shenzhen', 'female', 'music');
insert into db_test.tb_student values ('David', 70, 'Guangzhou', 'male', 'drawing');
insert into db_test.tb_student values ('Emily', 95, 'Hangzhou', 'female', 'cooking');

select tb_student* from tb_student,tb_course,tb_score,tb_teacher, WHERE tb_teacher.id='张三'. and tb_student.id=tb_score.studentid and tb_score.courseid=tb_course.id and tb_course.teacherid=tb_teacher.id

这是一个 SQL 查询语句，其目的是查询学生表中所有选了张三老师教授的课程的学生信息。该查询语句中的语法存在一些错误，应该修改为：

SELECT tb_student.*
FROM tb_student, tb_course, tb_score, tb_teacher
WHERE tb_teacher.teacher_name = '张三' AND tb_student.id = tb_score.studentid AND tb_score.courseid = tb_course.id AND tb_course.teacherid = tb_teacher.id;

具体的查询条件是：在学生表、课程表、成绩表、教师表中，分别对应的字段是 tb_student.id、tb_course.id、tb_score.studentid、tb_course.teacherid、tb_teacher.teacher_name，通过这些字段的关联，筛选出教师姓名为张三的课程对应的学生信息。

需要注意的是，该查询语句中的表名和字段名应该根据实际情况进行修改，同时建议使用 JOIN 关键字来进行表的连接，可以使 SQL 查询语句更加清晰易懂。

mysql在db_school数据库中建立tb_class,tb_course,tb_score,tb_student,student1

我是AI语言模型，我可以为您提供MySQL创建表的语句，以下是在db_school数据库中创建tb_class、tb_course、tb_score、tb_student、student1表的示例：

创建tb_class表：

CREATE TABLE tb_class (
class_id INT NOT NULL AUTO_INCREMENT,
class_name VARCHAR(50) NOT NULL,
PRIMARY KEY (class_id)
);

创建tb_course表：

CREATE TABLE tb_course (
course_id INT NOT NULL AUTO_INCREMENT,
course_name VARCHAR(50) NOT NULL,
PRIMARY KEY (course_id)
);

创建tb_score表：

CREATE TABLE tb_score (
score_id INT NOT NULL AUTO_INCREMENT,
student_id INT NOT NULL,
course_id INT NOT NULL,
score INT NOT NULL,
PRIMARY KEY (score_id),
FOREIGN KEY (student_id) REFERENCES tb_student(student_id),
FOREIGN KEY (course_id) REFERENCES tb_course(course_id)
);

创建tb_student表：

CREATE TABLE tb_student (
student_id INT NOT NULL AUTO_INCREMENT,
student_name VARCHAR(50) NOT NULL,
class_id INT NOT NULL,
PRIMARY KEY (student_id),
FOREIGN KEY (class_id) REFERENCES tb_class(class_id)
);

创建student1表：

CREATE TABLE student1 (
id INT NOT NULL AUTO_INCREMENT,
name VARCHAR(50) NOT NULL,
age INT NOT NULL,
PRIMARY KEY (id)
);
