{ "item_title" : "Advanced Snowflake SQL and Scripting for Data Engineering", "item_author" : [" Alex Ambrose "], "item_description" : "This in-depth, practical guide is written for data professionals, aspiring data engineers, analysts, and software developers who want to master Snowflake beyond basic SQL usage and develop real-world, production-ready data engineering skills. As organizations increasingly shift toward cloud-based data platforms, Snowflake has become one of the most powerful and widely adopted solutions for scalable data warehousing, analytics, and automation. This book is designed to help you not only understand Snowflake but to confidently build, optimize, and automate complex data workflows using its full SQL and scripting capabilities.The journey begins with a strong foundation in Snowflake SQL, ensuring you are fully comfortable working within a modern cloud data warehouse environment. You will learn how to create, insert, update, and delete data efficiently while understanding how Snowflake manages data storage and query execution behind the scenes. The book then progresses into advanced querying techniques, including complex joins, correlated and non-correlated subqueries, set operations, and grouping strategies that are essential for handling large-scale, real-world datasets. You will also explore how to structure queries for readability, maintainability, and performance optimization in enterprise environments.A significant portion of the book is dedicated to advanced analytics using SQL. You will learn how to apply analytic and window functions to solve real business problems such as running totals, moving averages, ranking systems, cohort analysis, and time-based comparisons. These techniques are essential for data reporting, business intelligence dashboards, and decision-making systems. By mastering these functions, you will be able to transform raw data into meaningful insights that support strategic business operations.Beyond traditional SQL, this book introduces Snowflake Scripting in a structured and practical way. You will learn how to extend SQL into procedural logic using variables, control flow statements such as IF-THEN-ELSE, loops, and robust exception handling techniques. This allows you to build dynamic scripts that can perform multi-step operations inside Snowflake without relying on external programming languages. These scripting capabilities are critical for automating repetitive tasks, orchestrating data transformations, and building intelligent data workflows directly inside the database layer.In addition, you will gain practical knowledge on building automated data pipelines using Snowflake features. This includes designing workflows that can ingest, transform, and deliver data efficiently while minimizing manual intervention. You will learn how to structure data engineering pipelines that are reliable, scalable, and optimized for performance in cloud environments. Real-world examples throughout the book demonstrate how these techniques are applied in actual business scenarios, helping you bridge the gap between theoretical knowledge and industry practice.Performance optimization is another key focus area of this book. You will learn how Snowflake executes queries, how to reduce query cost and execution time, and how to structure your SQL for maximum efficiency. Topics such as clustering, result caching, and query tuning strategies are discussed to help you build systems that perform well under heavy workloads and large datasets.By the end of this book, you will have developed a strong and practical mastery of Snowflake SQL and scripting, enabling you to confidently design, implement, and manage advanced data engineering solutions. You will be capable of building automated workflows, writing high-performance queries, developing reusable database logic, and contributing effectively to modern data-driven organizations. This book serves as both a learning resource and a professional roadmap for anyone aiming to excel in cloud-based data engineering with Snowflake.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/818/134/9798181348882_b.jpg", "price_data" : { "retail_price" : "30.00", "online_price" : "30.00", "our_price" : "30.00", "club_price" : "30.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
