Master advanced Oracle SQL techniques to analyze, optimize, and transform data for real-world business reporting and decision-making. In this course, you will build practical skills in Oracle SQL Developer by applying advanced SQL operators, designing efficient queries with views and indexes, and using conditional and analytic functions to solve complex data challenges.

You will begin by restructuring and summarizing datasets with CUBE, ROLLUP, GROUPING SETS, and UNPIVOT while improving query performance through views and indexes. As you progress, you will create logic-driven queries using CASE and DECODE, manage NULL values with NVL, NVL2, and COALESCE, and generate deeper business insights with analytic functions such as ROW_NUMBER, RANK, DENSE_RANK, and NTILE. Designed for learners seeking to strengthen their Oracle SQL skills for data analysis, business intelligence, and database management, this course emphasizes hands-on, case-study-driven practice rather than theory alone. By the end of the course, you will be able to optimize SQL queries, evaluate query performance, analyze multidimensional data, and build flexible, business-ready reporting solutions using advanced Oracle SQL techniques.
