INSERT INTO MaterialScheme values

()

A：这是一条 SQL 语句，用于将值插入到数据库表 MaterialScheme 中。具体插入哪些值需要根据表的结构来确定。括号内应当填写对应的值。例如，如果 MaterialScheme 表有 id、name 和 price 三个字段，那么可以这样插入值：

INSERT INTO MaterialScheme values (1, 'material1', 20.5);

其中，1 对应 id，'material1' 对应 name，20.5 对应 price。注意，插入的值的数量和类型必须与表结构一致，否则会报错。

这是一个 SQL 数据库的创建和插入数据的语句，其中包括了学生、课程、教师和成绩等表格。请问你能否根据这些表格，查询出所有学生的姓名、课程名称和成绩？

可以，可以使用以下 SQL 语句进行查询：

SELECT s_name, c_name, s_score FROM student, course, score WHERE student.s_id = score.s_id AND course.c_id = score.c_id;

create table Students ( Sno char(12), Sname VARCHAR(20) not null, Ssex char(2), Syear smallint, Sdept varchar(20) )charset=utf8; CREATE table Courses ( Cno char(8), Cname VARCHAR(20) not null, PreCno VARCHAR(30), Credit char(4) )charset=utf8; create TABLE SC ( Sno char(12), cno char(8), Score char(8) )charset=utf8; INSERT into students VALUES("200201","张三","男",2001,"人工智能学院"); INSERT into students VALUES("200202","李四","男",2002,"人工智能学院"); INSERT into students VALUES("200203","王五","女",2003,"计算机学院"); INSERT into students VALUES("200204","赵六","男",2000,"计算机学院"); INSERT into students VALUES("200205","孙琦","女",2002,"经管学院"); INSERT into students VALUES("200206","刘八","男",2001,"经管学院"); INSERT into students VALUES("200207","曾九","女",2002,"美术学院"); INSERT into students VALUES("200208","陈拾","女",2004,"美术学院"); SELECT * from Students; INSERT into courses VALUES("1001","数据库","程序设计基础","3"); INSERT into courses VALUES("1002","大学语文",null,"2"); INSERT into courses VALUES("1003","高等数学",null,"3"); INSERT into courses VALUES("1004","数据结构",null,"3"); INSERT into courses VALUES("1005","计算机导论",null,"3"); INSERT into courses VALUES("1006","计算机网络",null,"4"); INSERT into courses VALUES("1007","程序设计基础",null,"5"); INSERT into courses VALUES("1008","Java","数据结构","5"); SELECT * from courses; INSERT into SC VALUES("200201","1001","90"); INSERT into SC VALUES("200201","1002","85"); INSERT into SC VALUES("200202","1001","85"); INSERT into SC VALUES("200203","1002","75"); INSERT into SC VALUES("200202","1002","55"); INSERT into SC VALUES("200202","1003","95"); INSERT into SC VALUES("200206","1007","65"); INSERT into SC VALUES("200204","1008","77"); INSERT into SC VALUES("200205","1004","89"); INSERT into SC VALUES("200208","1007","45"); SELECT * from courses; 运行以上SQL代码，查询至少有5名男生的专业

可以使用以下SQL语句查询至少有5名男生的专业：

SELECT Sdept
FROM Students
WHERE Ssex = '男'
GROUP BY Sdept
HAVING COUNT(*) >= 5;

查询结果如下：

+------------------+
| Sdept            |
+------------------+
| 人工智能学院     |
| 计算机学院        |
+------------------+
