オラクルマスター教科書 Silver SQL Oracle Database SQL

The Silver SQL Oracle Database SQL instructional book has received mixed reviews from customers who have used it for exam preparation. Many users appreciate that the book covers the necessary syllabus comprehensively, allowing readers to develop a firm understanding of SQL concepts. Reviewers have highlighted that the practice problems and the mock exams included are particularly beneficial for exam readiness, asserting that these prepare them well for the actual test scenarios. This aspect has granted several users a sense of success, with some achieving passing scores after using the book alongside additional study materials. However, a recurring theme in the feedback is the observation that while the book provides a solid foundational understanding, it might not be sufficient on its own for optimal results in the examinations. Several customers have pointed out that they had to supplement their studies with additional resources or practice from other platforms to ensure passing grades. This sentiment is echoed by reviewers who felt that more comprehensive coverage of exam questions would be useful, indicating that although the content is quite clear, it may lack the depth necessary for some users to excel by relying solely on the book. In summary, this instructional book is deemed valuable for understanding SQL in the context of Oracle's certification but is best utilized alongside other resources for anyone looking to ensure a strong performance on the exams. **
