Natural Language to SQL Example

## ---BEGIN---
## 查询学生小明的各科目成绩
## ---自然语言转换---
SELECT score.score
FROM score
INNER JOIN student_course ON score.course_id = student_course.course_id
INNER JOIN student ON student_course.student_id = student.id
WHERE student.name = '小明'
## --- END ---

SQL Optimization Suggestions

# ---BEGIN---
# SELECT score.score
FROM score
INNER JOIN student_course ON score.course_id = student_course.course_id
INNER JOIN student ON student_course.student_id = student.id
WHERE student.name = '小明'
# ---SQL优化---
优化建议：
1. 索引优化：为 student 表的 name 字段创建索引，可加快 WHERE 条件查询速度。
2. JOIN 优化：先筛选出 name 为小明的 student 记录，再进行 JOIN，减少数据量。
3. 数据库设计优化：考虑将 student 与 student_course 合并为一张表，避免 JOIN。
4. 缓存优化：将查询结果缓存，避免重复查询。
