plsql中的增量函数 [英] increment function in plsql

问题描述

在大多数编程语言中，您可以像以下示例一样快速编写变量的增量:

In most programming languages you have a fast way to write an increment for a variable like the following examples:

inc(variableName);
variableName++;
variableName += 1;

Oracle Pl/Sql中有哪些方法可以执行此操作，而不是使用以下方法:

Which ways are there in Oracle Pl/Sql to do this instead of using the following:

variableName := variableName + 1;

推荐答案

列出了操作员没有等效的++或+=.恐怕您必须做很长的路要走.

There is no equivalent of ++ or +=. I'm afraid you have to do it the long way.

您可以编写自己的inc()函数，但这可能会使您的代码对其他人的可读性降低，因为它是非标准的.

You could write your own inc() function but that would probably make your code less readable to others as it would be non-standard.
