Contributed to the Baeldung/sql-tutorials repository by developing a comprehensive set of SQL row-processing demo scripts designed to illustrate practical techniques for iterating through database records. The work focused on implementing and documenting multiple row-by-row processing methods, including cursor-based loops, temporary tables, and WHILE loops, tailored for MySQL, PostgreSQL, and SQL Server. Emphasizing database management and SQL proficiency, the demos provided reusable instructional patterns to support learners in understanding cross-database row processing. The approach prioritized clarity and educational value, ensuring that each script demonstrated real-world SQL techniques for handling sequential data operations across different relational database engines.
