Description

SQL: Visual QuickStart Guide teaches SQL — the language of databases — to beginning and intermediate programmers. With SQL, you can create, alter, and drop tables, indexes, and views; insert, update, query, and delete data; and execute transactions to maintain the integrity of your data. This book covers the relational model, the core language for ANSI/ISO (standard) SQL, and product-specific variations for Microsoft Access, Microsoft SQL Server, Oracle, IBM DB2, MySQL, and PostgreSQL. Hundreds of examples of varied difficulty encourage you to experiment and explore. Extensive cross references make this book a good quick reference for experienced programmers.

Download

This book’s examples use the sample database books, described in “The Sample Database” in Chapter 2. To create books, download the zip file sql_vqs3_files.zip, expand it, and follow the instructions for your DBMS, listed below. The file readme.txt describes the distribution.

In addition to creating the tables described in “The Sample Database” in Chapter 2, the SQL scripts create additional tables used in other examples. If you’re running a DBMS locally (that is, on your own computer), then you’re the database administrator (DBA) and have all the privileges you need. If you’re connecting to a DBMS on a network server, then ask your DBA for connection parameters and the privileges to create, query, update, and drop databases and tables.

The instructions for creating the sample database explain how to use simple tools and settings. As you gain experience, you might want to switch to using the statement CREATE DATABASE to create new databases. CREATE DATABASE is a powerful but nonstandard SQL command, so its syntax and capabilities vary by DBMS; see your DBMS’s documentation. (Microsoft Access doesn’t support CREATE DATABASE, but you can create Access databases programmatically by using Visual Basic for Applications or C#.)
