| amazon bie sql questions: The Language of SQL Larry Rockoff, 2021-11-04 Get Started Fast with SQL! The only book you need to gain a quick working knowledge of SQL and relational databases. Many SQL texts attempt to serve as an encyclopedic reference on SQL syntax—an approach that is often counterproductive because that information is readily available in online references published by the major database vendors. For SQL beginners, it's more important for a book to focus on general concepts and to offer clear explanations and examples of what various SQL statements can accomplish. This is that book. Several features make The Language of SQL unique among introductory SQL books. First, you will not be required to download software or sit with a computer as you read the text. The intent of this book is to provide examples of SQL usage that can be understood simply by reading. Second, topics are organized in an intuitive and logical sequence. SQL keywords are introduced one at a time, allowing you to grow your understanding as you encounter new terms and concepts. Finally, this book covers the syntax of the latest releases of three widely used databases: Microsoft SQL Server 2019, MySQL 8.0, and Oracle 18c. Special “Database Differences” sidebars clearly show you any differences in syntax among these three databases, and instructions are included on how to obtain and install free versions of the databases. Use SQL to retrieve data from relational databases Apply functions and calculations to data Group and summarize data in a variety of useful ways Use complex logic to retrieve only the data you need Design relational databases so that data retrieval is easy and intuitive Update data and create new tables Use spreadsheets to transform your data into meaningful displays Retrieve data from multiple tables via joins, subqueries, views, and set logic Create, modify, and execute stored procedures Install Microsoft SQL Server, MySQL, or Oracle |

About the author: Hi, my name is Sylvia Moestl Vasilik. I've been a database programmer and engineer for more than 15 years, working at top organizations like Expedia, Microsoft, T-Mobile, and the Gates Foundation. In 2015, I was teaching a SQL Server Certificate course at the University of Washington Continuing Education. It was a 10 week course, and my students paid more than $1000 for it. My students learned the basics of SQL, most of the keywords, and worked through practice problems every week of the course. But because of the emphasis on getting a broad overview of all features of SQL, we didn't spend enough time on the types of SQL that's used 95% of the time--intermediate and advanced Select statements. After the course was over, some of my students emailed me to ask where they could get more practice. That's when I was inspired to start work on this book. |

| amazon bie sql questions: Expert T-SQL Window Functions in SQL Server 2019 Kathi Kellenberger, Clayton Groom, Ed Pollack, 2019-10-22 Become an expert who can use window functions to solve T-SQL query problems. Replace slow cursors and self-joins with queries that are easy to write and perform better. This new edition provides expanded examples, including a chapter from the world of sports, and covers the latest performance enhancements through SQL Server 2019. Window functions are useful in analytics and business intelligence reporting. They came into full blossom with SQL Server 2012, yet they are not as well known and used as often as they ought to be. This group of functions is one of the most notable developments in SQL, and this book shows how every developer and DBA can benefit from their expressive power in solving day-to-day business problems. Once you begin using window functions, such as ROW_NUMBER and LAG, you will discover many ways to use them. You will approach SQL Server queries in a different way, thinking about sets of data instead of individual rows. Your queries will run faster, be easier to write, and easier to deconstruct, maintain, and enhance in the future. Just knowing and using these functions is not enough. You also need to understand how to tune the queries. Expert T-SQL Window Functions in SQL Server clearly explains how to get the best performance. The book also covers the rare cases when older techniques are the best bet. What You Will Learn Solve complex query problems without cumbersome self-joins that run slowly and are difficult to read Create sliding windows in a result set for computing such as running totals and moving averages Return aggregate and detail data simultaneously from the same SELECT statement Compute lag and lead and other values that access data from multiple rows in a result set Understand the OVER clause syntax and how to control the window Avoid framing errors that can lead to unexpected results Who This Book Is For Anyone who writes T-SQL queries, including database administrators, developers, business analysts, and data scientists. Before reading this book, you should understand how to join tables, write WHERE clauses, and build aggregate queries. |
| amazon bie sql questions: Beginner SQL Programming Using Microsoft SQL Server Kalman Toth, 2012-09-01 Beginning level SQL (Structured Query Language) programming teach-by-practical-diagrams-&-examples book for developers, programmers, systems analysts and project managers who are new to relational database and client/server technologies. Practical SQL Server based training for database developers, database designers and database administrators (DBA), who know some SQL programming and database design, and who wish to refresh & expand their RDBMS development technology horizons. Familiarity with at least one computer programming language, Windows file system & Excel is assumed. Since the book is career advancement oriented, it has a great number of practical SQL queries (over 1,100 SELECT queries) and T-SQL scripts, plenty to learn indeed. The queries are based on historic and current SQL Server sample databases: pubs (PRIMARY KEYs 9, FOREIGN KEYs 10) , Northwind (PRIMARY KEYs 13, FOREIGN KEYs 13) and the latest AdventureWorks series. Among them: AdventureWorks, AdventureWorks2008, AdventureWorks2012 (PRIMARY KEYs 71, FOREIGN KEYs 90), & AdventureWorksDW2012 (PRIMARY KEYs 27, FOREIGN KEYs 44). The last one is a data warehouse database. The book teaches through vivid T-SQL queries how to think in terms of sets at a very high level, focusing on set-based operations instead of loops like in procedural programming languages. The best way to master T-SQL programming is to type the query in your own SQL Server Management Studio Query Editor, test it, examine it, change it and study it. Wouldn't it be easier just to copy & paste it? It would, but the learning value would diminish rapidly. You need to feel the SQL language in your DNA. SQL queries must pour out from your fingers into the keyboard. Why is knowing SQL queries by heart so important? After all everything can be found on the web so why not just copy & paste? Well not exactly. If you want to be an database development expert, it has to be in your head not on the web. Second, when your supervisor is looking over your shoulder, Charlie, can you tell me what is the total revenue for March?, you have to be able to type the query without documentation or SQL forum search and provide the results to your superior promptly. The book was designed to be readable in any environment, even on the beach laptop around or no laptop in sight at all. All queries are followed by results row count and /or full/partial results listing in tabular (grid) format. Screenshots are used when dealing with GUI tools such as SQL Server Management Studio. Mastery of SQL programming book likely to be sufficient for career advancement as a database developer. |

| amazon bie sql questions: Microsoft Access SQL Comprehensive Pindar E. Demertzoglou, 2012-10-15 This book is primarily intended for a training/educational environment in a college, University, or technical school. The goal is to start from point zero in Access 2010 SQL and arrive at the level of a skilled professional. To that purpose it contains 306 exercises in 31 chapters which the student can complete during class time. It also contains ten questions after each chapter which the instructor can use for in class discussions or test generation. There are 320 questions in total in the book. Finally, it contains sixty case studies, two at the end of each chapter, for additional work as homework or for sharpening the skills learned through each chapter. The book is the culmination of Pindaro's 12 years of MS Access teaching at the University level to freshmen students with all the inherited fun and challenges. After hundreds of labs and thousands of questions and comments from the students, Pindaro wrote this book to assist the students in becoming SQL experts so that they can be absolutely successful in the working environment. Currently, no matter the position, industry, or job function, it looks like everyone is asking for SQL skills. For the instructor, Pindaro tried to make this book as friendly as possible. First, he personally tested the book in class to see how the labs work in the real training environment. Second, he has provided a multitude of case studies and questions on real business scenarios so that the students can appreciate the power of SQL for work and business. Third, he has prepared a separate booklet of 64 pages that the instructor can receive as a pdf file (upon confirmation of instructor status) that includes the solutions to the case studies and provides hints for the code proposed. The goal is to learn how to use databases for real business tasks. Pindaro has worked on hundreds of business databases and operational systems for the last 19 years. |
