軟體簡介:
　
Whatever a database is being used for—websites, bookkeeping, sales and
inventory, or even the lowly to-do list—it's still all about the data.
Completely updated for 2014, SQL Essential Training is designed to help
users understand the most common language for database wrangling, SQL.
Beginning with a quick start introduction for those who want to start
working with data immediately, instructor Bill Weinman teaches all the
major features of SQL: creating tables; defining relationships; manipulating
strings, numbers, and dates; using triggers to automate actions; and
working with subselects and views. He offers a solid working knowledge
of the language, and shows how to retrieve and manage data efficiently.
The final chapter includes a real-world example of building a simple CRUD
(Create, Read, Update, and Delete) application using SQL.

Topics include:
‧Understanding SQL terminology and syntax
‧Creating new tables and records
‧Inserting and updating data
‧Writing basic SQL queries
‧Sorting and filtering
‧Accessing related tables with JOIN
‧Working with strings
‧Finding the numeric type of a value
‧Using aggregate functions and transactions
‧Updating a table with triggers
‧Creating views
