Introduction

• MySQL is not currently the best choice for massively complex data centre operations in very large enterprises (e.g. processing hundreds of millions of records in highly interdependent systems), but it is rapidly acquiring many of the features which have previously excluded it from this domain (e.g. transactions, sub-selects, triggers, etc).
• Although most of these features appear in the latest MySQL development releases, we are not yet confident enough of their maturity to recommend them for the largest business-critical applications.
• This course covers the basics of the SQL language as implemented by MySQL.
• The course is designed to give delegates practical experience in writing SQL statements using the MySQL client program and MySQL Query Browser.
