SQL is a fundamental skill for Power BI developers as it enables them to query, manipulate, and optimize data from relational databases. Developers must understand joins, indexing, subqueries, common table expressions (CTEs), and stored procedures to extract and preprocess data efficiently. Advanced SQL skills help optimize query performance, reduce data load times, and handle large datasets effectively. Power BI developers with SQL expertise can write direct query models, create views, and use partitioning techniques for improved data performance. SQL proficiency ensures seamless integration with SQL Server, PostgreSQL, MySQL, and cloud-based databases like Azure SQL.
