1. 查找学生的姓名、选修的课程名和成绩的存储过程:
```
CREATE PROCEDURE sp_GetStudentGrades
@StudentID INT
AS
BEGIN
SELECT s.StudentName, c.CourseName, g.Grade
FROM Students s
JOIN Grades g ON s.StudentID = g.StudentID
JOIN Courses c ON g.CourseID = c.CourseID
WHERE s.StudentID = @StudentID
END
```
调用该存储过程:
```
EXEC sp_GetStudentGrades @StudentID = 12345
```
2. 根据学生学号和姓名返回学生基本信息的存储过程:
```
CREATE PROCEDURE sp_GetStudentInfo
@StudentID INT,
@StudentName VARCHAR(50)
AS
BEGIN
SELECT *
FROM Students
WHERE StudentID = @StudentID AND StudentName = @StudentName
END
```
调用该存储过程:
```
EXEC sp_GetStudentInfo @StudentID = 12345, @StudentName = '张三'
```
3. 根据学生学号返回学生选修门数和平均分的存储过程:
```
CREATE PROCEDURE sp_GetStudentAvgGrade
@StudentID INT
AS
BEGIN
SELECT COUNT(*) AS Courses, AVG(Grade) AS AvgGrade
FROM Grades
WHERE StudentID = @StudentID
END
```
调用该存储过程:
```
EXEC sp_GetStudentAvgGrade @StudentID = 12345
```
4. 带两个参数的分页存储过程:
```
CREATE PROCEDURE sp_paging
@page INT,
@pageSize INT
AS
BEGIN
SELECT *
FROM (
SELECT ROW_NUMBER() OVER (ORDER BY StudentID) AS RowNum, *
FROM Students
) AS t
WHERE t.RowNum BETWEEN (@page - 1) * @pageSize + 1 AND @page * @pageSize
END
```
调用该存储过程:
```
EXEC sp_paging @page = 2, @pageSize = 10
```
