SQL in a Nutshell, 2nd Edition [Electronic resources] نسخه متنی

Who Should Read This Book?

SQL in a Nutshell, Second Edition, benefits
several groups of users. It is useful for programmers who require a
concise and handy SQL reference tool. It is useful for developers who
need to migrate from one SQL dialect to another. Finally, it is
useful for database administrators (DBAs) who need to both execute a
myriad of SQL statements to keep their enterprise databases up and
running, and create and manage objects such as tables, indexes, and
views.

This book is a reference work, not a tutorial. The writing is not
expository. For example, we won't explain the
concept of an elementary loop. Experienced developers already know
such things. You want the meat. So we will explain, for example, the
detailed workings of an ANSI standard cursor, how it works on each of
the database platforms we cover, the special capabilities of cursors
on each database platform, and the various pitfalls of cursors and
how to get around them.

While we don't intend for SQL in a
Nutshell, Second Edition, to be a tutorial on SQL or a
handbook for database design, we do provide some brief coverage of
those topics, and we hope you find that helpful. Chapter 1 and Chapter 2 provide
a concise introduction to SQL, covering the general origins,
essential structure, and basic operation of the language. If
you're new to SQL, the introductions in
Chapter 1 and Chapter 2 will help you to get started.
