Syntax of SQL queries differ from vendor to vendor. Setting constraints, writeup of queries differ from vendor to vendor. How has the book handled such SQL queries and what is the type of database(Oracle, SQL server, etc) referenced in the book?

For getting the right syntax, simply get a reference book. To understand joins, normalization, grants, roles, subqueries, buy this one. But buy this one first, so you know what syntax you need to look up.
