Book Synopsis SQL Server Interview Questions and Answers by : Vinod Kumar
Download or read book SQL Server Interview Questions and Answers written by Vinod Kumar and published by Independently Published. This book was released on 2021-03 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: As representatives from the IT community, all of us have had our own experiences of attending interviews - clearing or close to clearing and sometimes with tons of questions and doubts failing miserably. These stories are in the most pleasant or not so pleasant memories of our mind and we will assure you this book will kindle those memories for sure. We have taken tons of interviews and most of the interviews are not revolving around how deep technical and internals you know about the subject - but it revolves around how good you are with the basics.To clear an interview, one doesn't need to know inside-out of a subject, and subjects like "SQL Server" so vast that every single day we learn something new with this product, and even a complete lifetime will fly off if we keep doing this. Again, the various roles one can get into for products like SQL Server are from Database Developer, Database Modelers, Database Architect, Database Administrator and many more. Hence, this book is geared towards demystifying and a refresher for memories on the fundamentals which sometimes are the most important things to clear any type of interview for any role. Some of the concepts discussed are generic and are not tied to any specific version of SQL Server, but most of it the new features introduced with SQL Server have been included in this book.This book is not a shortcut or a sure to crack interview guide but this book gets you prepared in an organized manner. Let us also assure you this is neither a completely comprehensive guide but surely is a great starter nevertheless. Use this to guide you and be mentally prepared for the big day. When faced with this big day, we get overwhelmed and confused about where to start our preparation. And this book is just that secret recipe in your arsenal to get geared up. Sometimes these basics will help you narrow to a solution quickly when given a scenario.Now this book's flow is "Question & Answer" mode from start till the end to help you grasp the concepts faster and to the point. Once you get an understanding of concepts, then if we are twisted with the concept in a scenario it becomes easy to solve them. Most companies have a typical way to do interviews which are based on the scenario as per their environment and these are just combinations of the concepts to fit their need and SLA.Though each of these chapters is bucketed for convenience we highly recommend reading each of the sections nevertheless irrespective of the roles you might be doing as each of the sections have some interesting trivia's working with SQL Server. In the industry, the role of accidental DBA's especially with SQL Server is so common. Hence if you have performed the role of DBA for a short stink and want to brush-up your fundamentals then the respective sections will be a great skim.

Book Synopsis A PRACTICAL GUIDE TO Database Programming with PHP/MySQL by : Vivian Siahaan
Download or read book A PRACTICAL GUIDE TO Database Programming with PHP/MySQL written by Vivian Siahaan and published by SPARTA Publishing. This book was released on 2019-04-14 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: You will learn PHP/MySQL fast, easy and fun. This book provides you with a complete MySQL guidance presented in an easy-to-follow manner. Each chapter has practical examples with SQL script and screenshots available. If you go through the entire chapters, you will know how to manage MySQL databases and manipulate data using various techniques such as MySQL queries, MySQL stored procedures, database views, triggers. In the first part of the book, you will learn basic MySQL statements including how to implement querying data, sorting data, filtering data, joining tables, grouping data, subquerying data, dan setting operators. Aside from learning basic SQL statements, you will also learn step by step how to develop stored procedures in MySQL. First, we introduce you to the stored procedure concept and discuss when you should use it. Then, we show you how to use the basic elements of the procedure code such as create procedure statement, if-else, case, loop, stored procedure’s parameters. In the next chapter, we will discuss the database views, how they are implemented in MySQL, and how to use them more effectively. After that, you will learn how to work with the MySQL triggers. By definition, a trigger or database trigger is a stored program executed automatically to respond to a specific event e.g., insert, update or delete occurred in a table. The database trigger is powerful tool for protecting the integrity of the data in your MySQL databases. In addition, it is useful to automate some database operations such as logging, auditing, etc. Then, you will learn about MySQL index including creating indexes, removing indexes, listing all indexes of a table and other important features of indexes in MySQL. MySQL uses indexes to quickly find rows with specific column values. Without an index, MySQL must scan the whole table to locate the relevant rows. The larger table, the slower it searches. After that, you will find a lot of useful MySQL administration techniques including MySQL server startup and shutdown, MySQL server security, MySQL database maintenance, and backup. The last chapter gives you the most commonly used MySQL functions including aggregate functions, string functions, date time functions, control flow functions, etc.
