Are you a web designer or developer looking for guidance in learning SQL for your web projects? If you are, then this book is for you! Author Rudy Limeback, has done an outstanding job of writing a book about SQL.
Limeback, begins by putting the SQL language into a perspective relevant to a typical web developer. Next, the author dissects the SQL SELECT statement into its component and clauses and gives you a taste of what's to come. Then, he will ease you through the tricky subject of database table joins, where you'll easily master the concepts of the inner join, left outer join, right outer join, full outer join, and cross join. He continues by showing you how to express conditions using SQL keywords: LIKE, BETWEEN, AND, OR, IN, EXISTS, and NOT; as well as, correlated subqueries. Next, the author shows you how to group works and the rules for its use. Then, he shows you how to write HAVING clause conditions, and how to use the HAVING clause without a GROUP BY clause. The author continues by showing you how to use the SELECT clause effectively, and how its scope changes in the presence or absence of the GROUP BY clause. Next, he focuses on sequencing the various data types, and the difference between sequencing the various data types, and the difference between sequencing and grouping. He continues by providing a detailed look at the various numeric, character, and temporal data types available for columns, and the rationales for their use. Next, the author introduces some topics that are the source of much befuddlement for many people new to databases. Finally, the author examines some of the common database structures that can be used to implement complex relationship between entities.
This most excellent book explored all of the aspects of SQL and database design that are required by web developers to develop efficient and effective web pages. More importantly, it covered not only simple examples of SQL that are relevant to you, but also more complex concepts using terminology that is not too obscure.
