Database Updates and Deletes with Ecto in Elixir

Managing data persistence efficiently requires a solid understanding of how to modify and remove records without compromising system integrity. In Elixir applications, Ecto serves as the robust database wrapper and query generator, but performing updates and deletes requires careful execution to avoid common pitfalls. This course guides you through the core concepts of data manipulation, ensuring you can write safe, performant, and predictable database operations. You will start by mastering foundational Ecto concepts, understanding how changesets protect your data, and learning the difference between schema-less queries and schema-backed operations. From there, you will progress to executing targeted updates, batch operations, and safe deletion strategies. What you'll learn: - Understand the fundamentals of Ecto queries, changesets, and database transactions - Update single records safely using changesets and schema-backed queries - Perform bulk updates using Ecto.Query syntax for high-performance operations - Delete records precisely using both schema-based and query-based approaches - Handle database constraints and elegant error resolution during updates - Implement soft-delete patterns to preserve historical data integrity This text-based course is designed to take you from foundational syntax to real-world database manipulation patterns. Through clear written explanations and structured code examples, you will build a reliable mental model of how Ecto interacts with your database. This course is perfect for beginner to intermediate Elixir developers who want to deepen their database management skills. No prior experience with advanced Ecto queries is required, though a basic familiarity with Elixir syntax is recommended. Start writing clean, safe, and efficient Ecto queries today.
