In a DECODE function, Oracle considers two nulls to be equivalent. If expr is null, then Oracle returns the result of the first search that is also null. 但是要注意的是,为这条SQL选择索引,只能对id列创建,不能对decode函数创建,因为Oracle不能基于未知的用户输入创建索引数据, ...
在Python 3中,字符串(str)对象确实没有decode方法,这是因为Python 3中的字符串默认使用Unicode编码。Unicode是一种字符集,它包含了世界上大多数语言的字符,因此Python 3中的字符串可以直接处理各种语言的文本,而不需要像Python 2那样进行编码和解码。 基础概念 Unicode:一种字符编码标准,能够表示世界上大多...
