提问by nightfox79
In most programming languages you have a fast way to write an increment for a variable like the following examples:
在大多数编程语言中，您有一种快速的方法来为变量编写增量，如下例所示：
inc(variableName);
variableName++;
variableName += 1;
Which ways are there in Oracle Pl/Sql to do this instead of using the following:
Oracle Pl/Sql 中有哪些方法可以做到这一点，而不是使用以下方法：
variableName := variableName + 1;

The operators are listed in the documentation.
操作员在文档中列出。
There is no equivalent of ++or +=. I'm afraid you have to do it the long way.
没有相当于++或+=。恐怕你得走很长的路。
You could write your own inc()function but that would probably make your code less readable to others as it would be non-standard.
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。
