Some of the latest SQL tricks every analyst should know include using window functions for running totals, rankings, and moving averages—these reduce complex queries into clean, efficient logic. Modern SQL also supports CTEs (Common Table Expressions), which make large queries easier to read and debug. JSON functions are increasingly important for handling semi-structured data inside relational databases. Analysts should also master performance tuning with indexing and query optimization. Many advanced topics are now part of Google data analytics certification courses because they help analysts work faster, cleaner, and more accurately with large datasets.
