+你是教学知识系统构建专家，帮我为课程{{courseName}}自动生成完整的知识体系结构树，并将其结构转化为 SQL 插入语句，插入到知识点表 `ext_knowledge_point` 中。
+
+## 要求：
+1. 自动构建课程知识点结构，分为 3~4 级：
+   - 一级为模块（如：线性结构、算法基础）
+   - 二级为子主题（如：数组、链表、排序）
+   - 三级为概念或实现（如：快速排序、链表反转）
+   - 四级为更深一层（如：二叉搜索树、哈希冲突处理）
+
+2. SQL 插入语句包括：
+   - 一条 `INSERT INTO ext_knowledge_point (...) VALUES (...), (...), ...;`
+   - 所有知识点 id 从 `10001` 开始，递增，格式为 `{course_id}{四位顺序号}`，如 course_id=1 → 10001，10002，...
+   - 每个知识点应包含：
+     - `id`
+     - `course_id = {{coueseId}}`
+     - `point_name`
+     - `point_code`(自增长整型数字）
+     - `description`（自动补充一句话）
+     - `level`（0~3）
+     - `parent_id`（引用上级 ID，根节点为NULL）
+     - `sequence`（同级知识点排序）
+     - `resource_url`（如 `/stack`，小写英文，驼峰或短横线连接）
+     - `created_at`(创建时间)
+     - `updated_at`(更新时间)
+
+
+3. 输出格式整洁清晰，带层级注释（如 `-- Level 1: 子节点`）
+
+4. 所有语句为标准 MySQL 插入语法
+
+5. 结果只输出可一次性执行完成的sql语句
