Introduction

The Oracle database and the Structured Query Language (SQL) that
it supports are complex and ever changing products that have grown
increasingly complex and powerful over the years. This book is not an
attempt to teach the new Database Administrator (DBA) everything she or
he needs to know about how to administer an Oracle database. That would
be an interesting book challenge, but not the one we wanted to tackle.
Instead, we wrote the book we’ve both been wishing we had, but couldn’t
find anywhere. A simple reference to the Oracle version of SQL and some
of the critical tables and views that the practicing Oracle DBA needs
every day. This is a purely syntax reference, a quick way to get a
reminder of what options a command takes and the exact syntax required.

Most Oracle DBAs spend probably 90% of their time doing less than
5% of the tasks possible with an Oracle database. They neither need nor
want a book to give them the syntax for those commands they use every
day. But for the commands they may only use once every six months or
so, a little quick reminder can be helpful. And that’s the purpose and
intent of this book—to give the working DBA a little book that they can
keep on their desktop or next to the server where they can quickly look
up the syntax for the command they need, or find the right name for the
view they know exists, but haven’t had to use since the last time there
was a problem.

As Oracle has grown from our first days with Oracle 6 to the
complexity and power of Oracle 9i, the number of new commands, and
options and modifiers to the old ones, has grown enormously. If you’re
like us, you know there are new options and ways to do things, but
often need a quick reminder of the syntax or options available. We hope
you’ll find this book a useful tool for that.

How To Use This Book

This book is divided up into three basic sections:

* Chapter 1—covers the operators and functions recognized by
Oracle SQL, as well as the format models, privileges and reserved
words, organized into easy to read tables and grouped by the type of
function, operator, privilege, or format model involved.

* Chapter 2—is a complete SQL command reference, showing the
syntax and options for every Oracle SQL command supported by Oracle 9.2
from ALTER CLUSTER to UPDATE, in alphabetical order. We have used
standard “railroad” syntax diagrams to make it easy to follow the
options and syntax required.

* Chapter 3—is a listing of the data dictionary views that are a
part of every DBA’s life, and the dynamic performance tables that
provide a wealth of information about what is happening inside the
database. In the interest of keeping to our design goal of making this
a short, easy-to-use and quick reference, we stuck to a simple listing
of the tables and views here. The names make it pretty clear what each
covers, and as working DBAs we’ve found that’s really all we need. Once
we know the name, a simple DESCRIBE will get the rest.

A note on the syntax diagrams in Chapter 2. Certain clauses show
up across a wide range of commands with no change in the syntax or
options they support. In order to keep the diagrams as simple as
possible, we have grouped those clauses at the end of the chapter under
“Common.” The clauses covered there are:

* Allocate Extent

* Constraints

* Deallocate Unused

* File Specification

* Logging

* Parallel

* Physical Attributes

* Storage

Within each command, we have broken out the syntax for the less
common clauses immediately following the main command. This enables a
simpler and more readable diagram while providing full information. We
have underlined the names of subordinate clauses in the diagrams to
make it clear that you need to break out of the main diagram for the
syntax to that clause.
