                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 ...
