Lynn Beighley is a fiction writer stuck in a technical book writer's body. Upon discovering that technical book writing actually paid real money, she learned to accept and enjoy it. After going back to school to get a Masters in Computer Science, she worked for the acronyms NRL and LANL. Then she discovered Flash, and wrote her first bestseller. A victim of bad timing, she moved to Silicon Valley just before the great crash. She spent several years working for Yahoo! and writing other books and training courses. Finally giving in to her creative writing bent, she moved to the New York area to get an MFA in Creative Writing. Her Head First-style thesis was delivered to a packed room of professors and fellow students. It was extremely well received, and she finished her degree, finished Head First SQL, and can't wait to begin her next book.
Lynn loves traveling, cooking, and making up elaborate background stories about complete strangers. She's a little scared of clowns.

It's possible to skip the php substr() function and limit the job description data in the SQL query itself.You use a very similar MySQL function called SUBSTRING() that accepts the same arguments as substr(). The only difference is that the starting index starts at 1 instead of 0.So grabbing the first 100 characters of the job description looks like this:
SELECT SUBSTRING(job_description, 1, 100) FROM riskyjobs; (查看原文)
Remember that our goal is to simplify the messy Mismatch queries with INNER JOIN.When an inner join involves matching columns with the same name, we can further simplify the query with the help of USING statement.The USING statement takes the place of ON in an INNER JOIN query, and requires the name of the column to be used in the match.Just make sure the column is named exactly the same in both tables.As an example, here's the Mismatch query again:
SELECT mismatch_topic.topic_id, mismatch_category.name FROM mismatch_topic INNER JOIN mismatch_category USING (category_id) WHERE mismatch_topic.name = 'Horror movies' (查看原文)

HF的书都比较生动，但内容也有点浅，要实用还需要其它材料补充。
