By the end of this course, learners will be able to apply advanced SQL operators, design efficient queries using views and indexes, and implement analytic and conditional functions to solve real-world business problems. Participants will learn how to restructure and aggregate data with CUBE, ROLLUP, and GROUPING SETS, as well as handle NULL values using NVL, NVL2, and COALESCE.

This course goes beyond theory by offering case-study-driven practice in Oracle SQL Developer, ensuring learners gain hands-on experience with query optimization and advanced reporting. Learners will not only understand how to write SQL code but also evaluate performance impacts, analyze multidimensional data, and design logic-driven queries for decision-making. What makes this course unique is its practical approach, combining foundational SQL structures with advanced business-ready techniques such as DECODE, CASE, and ranking functions like ROW_NUMBER, RANK, and DENSE_RANK. By completing this course, learners will confidently create optimized, flexible, and insightful SQL queries that are essential for careers in data analytics, business intelligence, and database management.

This module introduces learners to the foundational building blocks of Oracle SQL queries with a focus on data structuring and advanced operators. Learners will explore how to simplify reporting using CUBE, UNPIVOT, and GROUPING SETS, along with optimizing performance through views and indexes. By the end of this module, learners will confidently analyze and manipulate datasets using grouping, summarization, and retrieval optimization techniques that are essential in real-world business intelligence and database management.
