    For SQL beginners, it's more important for a book to focus on general concepts and offer clear explanations and examples of what the various statements can accomplish. This is that beginner book. A number of features make The LANGUAGE OF SQL unique among introductory SQL books. First, you will not be required to download software or sit with a computer as you read the text. The intent of this book is to provide examples of SQL usage that can be understood simply by reading them. Second, topics are organized in an intuitive and logical sequence. SQL keywords are introduced one at a time, allowing you to build on your prior understanding as you encounter new words and concepts. Finally, this book covers the syntax of three widely used databases: Microsoft SQL Server, MySQL, and Oracle, with special "Database Differences" boxes that will show you any differences in the syntax among those three databases, as well as instructions on how to obtain and install free versions of the databases. This is the only book you'll need to gain a working knowledge of SQL and relational databases.

    Miki grew up in the small town of Levice in Czechoslovakia. In 1944, his life changed forever. At the age of 13, Miki and his family were sent to the concentration camps at Auschwitz. Miki survived against all odds and ultimately triumphed to live a life of love. “Miki Popik shares an incredible tale of survival, courage and resilience. He speaks of his life as a child in Czechoslovakia at the dawn of World War II, of his imprisonment at two concentration camps, of his family’s struggles for survival, and his efforts after the war to locate his family. Though he was the only one from his extended family to survive, he felt very fortunate to have learned where in a mass grave in Mühldorf, Germany, his father and brother had been interred. Mühldorf was a sub-camp of the infamous Dachau, not far from Munich. Miki’s story moves like none other.” – Alan S. Blaustein, JD, MD “In 2012, my classmates and I from the Sherman Block Supervisory Leadership Institute were fortunate to hear you speak at the Museum of Tolerance. Your words were truly inspiring! I left the museum that day speechless and humbled. I realized that nothing in my life can be assimilated to what you have experienced in yours. It shed a new light on the human race and how we treat one another.” – Sergeant Robert O’Brine, San Bernardino County Sheriff’s Dept.
