SQL, the universal language of databases, looks simple and is often used by developers as if it is, but in fact its relatively few but very powerful commands and the necessity of it being invoked by general-purpose languages such as C++, Java, Python and Perl make it a sophisticated tool that can solve difficult problems with a single statement. This introductory text aims at a solid understanding of SQL language and standard syntax in a practical format, covering creating and populating a database, querying (including querying multiple tables), filtering, working with sets, generating data (and converting and manipulating it), grouping, making sub-queries, and working with joins, conditional logic, transactions, indexes and constraints.
