Larry Rockoff, "The
Language of SQL: How to Access Data in Relational Databases" 240 pages | PDF | 15,4 MB
Most SQL texts attempt to serve as an encyclopedic reference on
SQL syntax -- an approach that is counterproductive, since this information is
readily available in
online references published by the major database vendors. For SQL beginners,
it's more important for a book to
focus on general concepts and offer clear explanations and examples of what the various statements can accomplish. This is
that beginner book. A number of features make The LANGUAGE OF SQL unique
among introductory SQL books. First, you will not be required to download software or sit with a computer as you read the text. The
intent of this book is to provide examples of SQL usage
that can be understood simply by reading them. Second, topics are organized in
an intuitive and logical sequence. SQL keywords are introduced one at a time,
allowing you to build on your prior understanding as you encounter new words
and concepts. Finally, this book covers the syntax of three widely
used databases: Microsoft SQL Server, MySQL, and Oracle, with special
"Database Differences" boxes that will show you any differences in
the syntax among those three databases, as well as instructions on how to obtain and
install free versions of the databases. This is the only book you'll
need to gain a working knowledge of SQL and relational databases.
