Order by specify the order of the window in the group by statement. The Order by clause is a keyword in the Oracle Analytic syntax that is requirement for using some Analytic functions Analytic functions are the last set of operations performed in a query except for the final ORDER BY clause...

分析函数是oracle 8中引入的一个概念,为我们分析数据提供了一种简单高效的处理方式. 官方对分析函数的说明如下: Analytic functions compute an aggregate value based on a group of rows. They differ fromaggregate functions in that they return multiple rows for each group. The groupof rows is called a ...

学习Oracle分析函数(Analytic Functions) Oracle提供了一些功能很强大的分析函数,使用这些函数可以完成可能需要存储过程来实现的需求。 分析函数计算基于一组数据行的聚合值,它们不同于聚合函数的是,它们为每一组返回多行结果。分析函数是除ORDER BY子句之外,在查询语句中最后执行的。所有的join和所有的WHERE ,GROUP BY...
Introduction to Analytic Functions (Part 1) Analytic functions have been part of Oracle for a very long time now – ever since 8i back in 1999. Analytic functions are an ANSI/ISO standard, and so you’ll find that they are similarly-implemented across a number of compliant databases. ...
