Hello fellow data enthusiasts! Peacock Anderson’s “SQLServer文法2：クエリ” on Udemy is a fantastic follow-up course for anyone looking to deepen their understanding of SQL Server query techniques. This course picks up where the foundational “SQLServer文法１” leaves off, diving straight into various advanced search methods that are crucial for effective data manipulation.
Peacock Anderson expertly guides learners through a comprehensive syllabus covering comparison operators, range specifications, the IN clause, LIKE clauses for pattern matching, aggregate functions, the powerful GROUP BY clause, subqueries, UNION for combining result sets, DISTINCT for unique values, and the TOP clause for limiting results. The course is structured to systematically cover these essential query building blocks, making it an ideal resource for those who want to solidify their SQL grammar or refresh their knowledge.
What I particularly appreciated about this course is its focused approach. It assumes a basic understanding of SELECT, FROM, WHERE, and table joins (covered in the first course), allowing it to delve directly into more nuanced and practical query writing. If you’ve had some exposure to SQL, you can jump right into this course and find it quite accessible. For absolute beginners, however, it’s highly recommended to complete “SQLServer文法１” first to build a solid foundation.
Overall, “SQLServer文法2：クエリ” is a well-organized and informative course that provides practical skills for anyone working with SQL Server. It’s a great investment for improving your querying abilities and gaining more confidence in your data analysis tasks. I highly recommend it!
