{"product_id":"9781937842321","title":"SQL Tricks (Advanced Database Programming)","description":"\u003cp\u003eThis cookbook of advanced techniques is for anyone who knows the basics of SQL and wants to move beyond simple SELECT-FROM-WHERE queries. You'll find solutions to problems that analysts, app developers, and database programmers often face, from simple tasks, like picking random rows, to complex operations, like traversing hierarchies. Each recipe includes a discussion of the underlying logic, important concepts, and best practices. Take full advantage of standard (ANSI\/ISO) SQL, or use DBMS-specific features that dramatically extend the power of standard SQL. Use the scores of code examples directly in real-world DBMS applications, or as a source of insight for related problems.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCovers Oracle, Microsoft SQL Server, IBM DB2, MySQL, PostgreSQL, and Microsoft Access.\u003c\/li\u003e\n\u003cli\u003eImplement cross-platform solutions in standard SQL, or DBMS-specific solutions for your particular system.\u003c\/li\u003e\n\u003cli\u003eSQL code listings help you see the elements and structure of the language.\u003c\/li\u003e\n\u003cli\u003eDownload the sample database and code listings to follow along with the author's examples.\u003c\/li\u003e\n\u003cli\u003ePlenty of tips, tricks, and timesavers.\u003c\/li\u003e\n\u003cli\u003eFully indexed and cross-referenced.\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cp\u003eContents\u003c\/p\u003e\u003cp\u003eIntroduction\u003c\/p\u003e\u003cp\u003e1.
