好的,根据您提供的存储过程,执行以下SQL语句即可查询东方配件厂的供应商号、零件名、数量和价格。
```
EXEC SPJCX '东方配件厂';
```
这将会返回符合条件的查询结果。注意要确保数据库连接已经建立,并且存储过程已经正确创建。

CREATE PROCEDURE s_grade @sno char(20) AS BEGIN SELECT student.sno, student.sname, course.cname, sc.grade FROM student INNER JOIN sc ON student.sno = sc.sno INNER JOIN course ON sc.cno = course.cno END
这段代码是一个 SQL 存储过程,名为 s_grade,接收一个名为 @sno 的 char(20) 类型参数。该存储过程查询了学生表(student)、成绩表(sc)和课程表(course),通过内连接将它们关联起来,最终返回指定学号 @sno 的学生的所有课程成绩信息,包括学号(sno)、姓名(sname)、课程名(cname)和成绩(grade)。
select c.id as cid, c.name as cname, s.id as sid, s.code , s.name as sname, s.gender, s.age, t.id as id, t.name as name -- from student s,teacher t,class c where s.class_id=c.id -- and t.id=(select c.teacher_id from class c where c.id=#{id}) from class c left outer join student s on c.id=s.class_id left OUTER join teacher t on t.id=c.teacher_id where c.id = 1用嵌套方式怎么写
以下是使用子查询的方式来嵌套查询:
```
SELECT c.id as cid, c.name as cname, s.id as sid, s.code, s.name as sname, s.gender, s.age, t.id as tid, t.name as tname
FROM (
SELECT * FROM class WHERE id = 1
) c
LEFT OUTER JOIN student s ON c.id = s.class_id
LEFT OUTER JOIN teacher t ON c.teacher_id = t.id;
```
注意,这里的子查询 `SELECT * FROM class WHERE id = 1` 返回的结果只有一行,因为我们指定了 `id = 1`,所以外层的 `LEFT OUTER JOIN` 只会返回这个班级的所有学生和对应的老师信息。
