In the world of database development, efficient code is paramount. Slow-running PL/SQL can be a major bottleneck, impacting application performance and user experience. Fortunately, Udemy’s ‘PL/SQL Tuning’ course offers a comprehensive guide to transforming your PL/SQL code from sluggish to lightning-fast.
This course, delivered in Portuguese, is packed with over 30 practical tips, complete with clear explanations and live demonstrations. It covers a wide array of optimization techniques, making it an invaluable resource for any Oracle developer. Here’s a glimpse into what you’ll learn:
**Key Optimization Techniques Covered:**
* **`DBMS_TRACE`:** Master the `DBMS_TRACE` package to precisely analyze the execution time of your PL/SQL blocks, including the SQL statements executed within them.
* **Numeric Data Types:** Understand which numeric data types offer the best performance based on your compilation mode.
* **`DBMS_SHARED_POOL`:** Learn how to use `DBMS_SHARED_POOL` to ‘pin’ essential PL/SQL objects in the Shared Pool, ensuring faster access.
* **`RETURNING` Clause:** Discover how to leverage the `RETURNING` clause to optimize SQL statements within stored procedures.
* **`NOCOPY` Hint:** Boost the performance of function and procedure calls that handle large objects, such as collections, with the `NOCOPY` hint.
* **Function Usage:** Make informed decisions about when to use functions, balancing code reusability with performance considerations.
* **Dynamic SQL:** Understand the trade-offs between writing less code with dynamic SQL and its performance implications.
* **Bind Variables:** Grasp the concept of bind variables and learn how and when to effectively utilize them.
* **Native Compilation:** Explore native compilation, understanding what it is and when it’s beneficial to employ it.
* **Function Result Cache:** Dive into ‘Function Result Cache’ and learn how and when to implement it for performance gains.
* **Pipelined Table Functions:** Get acquainted with ‘Pipelined Table Functions’ and their optimal use cases.
* **Bulk Binding:** Master ‘Bulk Binding’ techniques for significant performance improvements.
* **`CURRENT OF` Clause:** Optimize PL/SQL blocks that update data with conditional logic using the `CURRENT OF` clause.
* **When to Avoid PL/SQL:** Gain insights into scenarios where pure SQL is a more performant alternative to PL/SQL.
* **Deterministic Functions:** Understand deterministic functions and their appropriate usage.
* **Short-Circuit Evaluation:** Learn about short-circuit evaluation and its impact on code execution.
* **Stored Procedures:** Determine the best times to use stored procedures for optimizing transactions.
