Thinking of migrating to PostgreSQL? This clear, fast-paced introduction helps you understand and use this open source database system. Not only will you learn about the enterprise class features in versions 9.5 to 10, youâ??ll also discover that PostgeSQL is more than a database systemâ??itâ??s an impressive application platform as well.
With examples throughout, this book shows you how to achieve tasks that are difficult or impossible in other databases. This third edition covers new features, such as ANSI-SQL constructs found only in proprietary databases until now: foreign data wrapper (FDW) enhancements; new full text functions and operator syntax introduced in version 9.6; XML constructs new in version 10; query parallelization features introduced in 9.6 and enhanced in 10; built-in logical replication introduced in Version 10.e.
If youâ??re a current PostgreSQL user, youâ??ll pick up gems you may have missed before.
Learn basic administration tasks such as role management, database creation, backup, and restoreApply the psql command-line utility and the pgAdmin graphical administration toolExplore PostgreSQL tables, constraints, and indexesLearn powerful SQL constructs not generally found in other databasesUse several different languages to write database functionsTune your queries to run as fast as your hardware will allowQuery external and variegated data sources with foreign data wrappersLearn how to use built-in replication to replicate data

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 standardsFundamental concepts necessary for understanding relational databases and SQL commandsAn alphabetical command reference to SQL statements, according to the SQL:2016 ANSI standardThe implementation of each command by MySQL, Oracle, PostgreSQL, and SQL ServerAn alphabetical reference of the ANSI SQL:2016 functions and constructs as well as the vendor implementationsPlatform-specific functions unique to each implementation
