Advanced SQL

Advanced SQL refers to a deeper level of proficiency and understanding in using Structured Query Language (SQL) for database management and manipulation. It encompasses advanced techniques and features beyond basic SQL queries, including complex data retrieval, optimization, performance tuning, and database administration tasks. Advanced SQL skills often involve expertise in writing sophisticated queries involving multiple tables, subqueries, joins, aggregations, and window functions. Additionally, knowledge of SQL programming, stored procedures, triggers, and transactions is commonly associated with advanced SQL proficiency. This level of expertise is essential for database developers, data analysts, data engineers, and database administrators working with large-scale databases and complex data structures.
