SQL in a nutshell : a desktop quick reference

"SQL (Structured Query Language) is a standardized query language for maintaining and querying database information. Historically, SQL has been the choice for database management systems running on minicomputers and mainframes. Increasingly, however, SQL is being adapted to PC systems that support distributed databases and allow users on a local-area network to access the same data simultaneously. Although there are different dialects of SQL, it is the closest thing to a standard query language that currently exists." "SQL in a Nutshell is a practical and useful command reference to the latest release of the Structured Query Language standard (SQL99), which assists readers in learning how their favorite database product supports any standard SQL command. This book presents each of the SQL commands and describes its use in both commercial (Microsoft SQL Server 2000 and Oracle 8i) and open source (MySQL, PostgreSQL 7.0) implementations. Each command reference includes the command syntax (by vendor, if the syntax differs across implementations), a description, and informative examples that illustrate important concepts and uses." "SQL in a Nutshell is more than a convenient reference guide for experienced SQL programmers, analysts, and database administrators. It's also a great learning resource for novice and auxiliary SQL users, such as system administrators, users of packaged client/server products, and consultants who need to be familiar with the various SQL dialects across many platforms."--Jacket. This desktop reference documents every SQL command and how to use it in both commercial and open source implementations. It includes the command syntax, a description and practical examples. It also explains the leading commercial and open sources database product implement SQL, all in an easy-to-use format. For programmers, analysts, and database administrators, this Nutshell guide is the essential reference for the SQL language used in today's most popular database products. This new fourth edition clearly documents SQL commands according to the latest ANSI/ISO standard and details how those commands are implemented in Microsoft SQL Server 2019 and Oracle 19c, as well as in the MySQL 8, MariaDB 10.5, and PostgreSQL 14 open source database products. You'll also get a concise overview of the relational database management system (RDBMS) model and a clear-cut explanation of foundational RDBMS concepts--all packed into a succinct, comprehensive, and easy-to-use format. Sections include: Background on the relational database model, including current and previous SQL standards Fundamental concepts necessary for understanding relational databases and SQL commands An alphabetical command reference to SQL statements, according to the SQL:2016 ANSI standard The implementation of each command by MySQL, Oracle, PostgreSQL, and SQL Server An alphabetical reference of the ANSI SQL:2016 functions and constructs as well as the vendor implementations Platform-specific functions unique to each implementation For programmers, analysts, and database administrators, this Nutshell guide is the essential reference for the SQL language used in today's most popular database products.
