Oracle PLSQL 21c: Apply, Analyze & Build Programs

Build a practical foundation in Oracle PL/SQL 21c and learn to create structured programs that handle data accurately and make logical decisions. This course guides you through declaring and applying variables, distinguishing constants from variable constraints, and using %TYPE and %ROWTYPE to maintain datatype consistency. You will also work with procedures for modular programming, manipulate and compare strings with LIKE, CHAR, and VARCHAR2, and control program flow using IF-THEN-ELSE and CASE expressions. Designed for beginners and intermediate SQL users, the course helps you translate business requirements into clear PL/SQL blocks and reusable procedures. Through hands-on examples, practice quizzes, and graded assessments, you will strengthen problem-solving skills, improve coding accuracy, and apply reliable data-handling techniques to workplace programming scenarios. The course’s step-by-step structure makes it distinctive: you progress from variables, constants, and constraints to datatype management and conditional logic. By the end, you will be able to design, implement, analyze, and evaluate Oracle PL/SQL solutions with greater clarity and precision.
