SQL Programming and Procedural Logic - Mandarin Chinese

在本课程中,您将在 Databricks 中探索核心 SQL 编程和过程逻辑技能,重点学习如何构建模块化、可维护且面向生产的分析 Workflows。您将从学习关键 SQL 构造开始,例如公用表表达式(包括高级递归 CTE)、会话范围对象(如临时视图和表),以及用户自定义函数——这些构造能使您的 SQL 开发更加简洁且可复用。课程随后将引导您通过复合语句、变量、控制流、条件判断、循环和健壮的错误处理等高级 SQL 脚本技术,创建结构化且灵活的 SQL 流程。您还将学习如何利用符合 ACID 规范的多语句事务,确保这些多步骤管道中的数据一致性。最后,您将了解如何将逻辑封装到 SQL 存储过程中,并使用 LakeFlow Jobs 和迁移策略编排复杂 Workflows,将遗留任务转化为模块化、自动化的管道,从而充分发挥 Databricks 平台的全部能力。


注意:Databricks Academy 正在将 Databricks 环境中的课堂课程转为基于 notebook 的形式,并停止在讲座中使用幻灯片。您可以在 Vocareum 实验环境中访问课程 notebook。
