We review some common reporting functions in Chapter 2 Our Approach to SQL In addition to a basic knowledge of SQL, we will call attention to “our way” of developing queries in SQL The way we develop queries in SQL is often by beginning with a simple command and then building upon it until the answer is found There are different approaches to building queries in SQL as in any other language One way... to be used by Oracle professionals as well as students, but it is not a SQL primer Readers of this book are expected to have previously used Oracle, SQL* Plus, and, to some extent, PL /SQL This book can be used for individual study or reference, in advanced Oracle training settings, and in advanced xi Preface database classes in schools It is meant for those familiar with SQL programming since most of... gives: POWER(VALUE,2) - 81 Ordinary Trigonometry Functions SQL s ordinary trigonometry functions include: SIN — Returns the sine of a value COS — Returns the cosine of a value TAN — Returns the tangent of a value The SIN, COS, and TAN functions take arguments in radians where, radians = (angle * 2 * 3 .14 16 / 360) To illustrate the use of the ordinary trigonometric functions, let’s suppose we have .
