SQL is the means by which you tell the server how to perform data management operations, and fluency with it is necessary for effective communication. This chapter covers how to use SQL to manage data, including changing the SQL mode to affect server behavior, referring to elements of databases, using multiple character sets, creating and destroying databases, tables, and indexes, obtaining information about databases and their contents, retrieving data using joins, subqueries, and unions, using multiple-table deletes and updates, performing transactions that enable statements to be grouped or canceled, setting up foreign key relationships, and using the FULLTEXT search engine.
This chapter presents the most important problems you’ll have to solve when working with arrays—and, of course, solutions for these problems.
