“AS"和“AS"有什么区别?和“是"在 Oracle 存储过程中?

What is the difference between quot;ASquot; and quot;ISquot; in an Oracle stored procedure?(“AS和“AS有什么区别?和“是在 Oracle 存储过程中?)

问题描述

我看到 Oracle 程序有时用AS"编写，有时用IS"关键字编写.

I see Oracle procedures sometimes written with "AS", and sometimes with "IS" keyword.

CREATE OR REPLACE Procedure TESTUSER.KILLINSTANCE (INSTANCEID integer) **AS**
...

对比

CREATE OR REPLACE Procedure TESTUSER.KILLINSTANCE (INSTANCEID integer) **IS**
...

两者有区别吗?

<小时>显然，两者之间没有功能差异，但有些人遵循约定，当 SP 是包的一部分时使用AS"，而当它不是时使用IS".或者反过来.嗯.

---

Apparently, there is no functional difference between the two, but some people follow a convention to use "AS" when the SP is part of a package and "IS" when it is not. Or the other way 'round. Meh.

推荐答案

无.它们是同义词，旨在使您的代码更具可读性:

None whatsover. They are synonyms supplied to make your code more readable:

功能 f IS ...

FUNCTION f IS ...

CREATE VIEW v AS SELECT ...

CREATE VIEW v AS SELECT ...
