If you’re aiming to strengthen your SQL skills, especially in querying data efficiently, the ‘SQLServer文法2：クエリ’ course on Coursera is an excellent resource. Taught by Peacook Anderson, this course delves into various search techniques and query structures within SQL Server, making it highly beneficial for learners who want to deepen their understanding beyond basic SQL commands.
The course systematically covers essential topics such as comparison operators, range searches, IN and LIKE clauses, aggregate functions, GROUP BY, subqueries, UNION, DISTINCT, and TOP. It is designed to fill in the gaps for those who have some familiarity with SQL but need a structured overview of search methodologies. Notably, it builds upon foundational concepts like SELECT, FROM, WHERE, and table joins, which are covered in a separate introductory course. This separation allows learners to choose where to start based on their current knowledge level.
What sets this course apart is its practical approach to teaching complex query techniques in a clear and concise manner. Whether you’re self-studying or reviewing SQL concepts, this course offers a well-organized and comprehensive curriculum that will certainly boost your confidence in writing advanced queries.
I highly recommend this course for anyone looking to refine their SQL querying skills, especially if you want to write more efficient and sophisticated database queries. It’s suitable for beginners with some SQL experience or those seeking a solid review before moving on to more advanced topics.
