This book covers Structured Query Language (SQL), the standard that
defines how to create and manipulate databases and the data that they
store. It works well on two levels: As an in-depth yet concise tutorial
on how to use the language, with lots of clearly worked examples and as
a handy desktop reference on SQL implementation, covering all the major
SQL statements that you're likely to need when programming databases,
with example code for five major database systems: SQL Server, Oracle,
DB2, MySQL, and Access.
