Get started on mastering the one language binding the entire database industry. That language is SQL, and how it works is must-have knowledge for anyone involved with relational databases, and surprisingly also for anyone involved with NoSQL databases. SQL is universally used in querying and reporting on large data sets in order to generate knowledge to drive business decisions.Good knowledge of SQL is crucial to anyone working with databases, because it is with SQL that you retrieve data, manipulate data, and generate business results. Every relational database supports SQL for its expressiveness in writing queries underlying reports and business intelligence dashboards. Knowing how to write good queries is the foundation for all work done in SQL, and it is a foundation that Clare Churcher's book, Beginning SQL Queries, 2nd Edition, lays well.What You Will LearnWrite simple queries to extract datafrom a single tableCombine data from many tables into one business result using set operationsTranslate natural language questions into database queries providing meaningful information to the businessAvoid errors associated with duplicated and null valuesSummarize data with amazing ease using the newly-added feature of window functionsTackle tricky queries with confidence that you are generating correct resultsInvestigate and understand the effects of indexes on the efficiency of queriesWho This Book Is ForBeginning SQL Queries, 2nd Edition is aimed at intelligent laypeople who need to extract information from a database, and at developers and other IT professionals who are new to SQL.

Beginning SQL Queries, 2nd Edition is a friendly and easily read guide to writing queries with the all-important — in the database world — SQL language. Anyone who does any work at all with databases needs to know something of SQL, and that increasingly today includes those using so-called NoSQL databases, because a strong trend in the industry is to make those databases accessible from SQL after all, at least for reporting purposes, and for analysis. Beginning SQL Queries, 2nd Edition is written by the author of Beginning Database Design, an author who is garnering great reviews on Amazon due to the clarity and succinctness of her writing.
