多条sql执行时如果在中间的语句出现错误，后续会不会直接执行，如何进行设定，以及其他数据库诸如Mysql是如何对应的，这篇文章将会进行简单的整理和说明。

环境准备

使用Oracle的精简版创建docker方式的demo环境，详细可参看：

多行语句的正常执行

对上篇文章创建的两个字段的学生信息表，正常添加三条数据，详细如下：

# sqlplus system/liumiao123@XE <<EOF
> desc student
> select * from student;
> insert into student values (1001, 'liumiaocn');
> insert into student values (1002, 'liumiao');
> insert into student values (1003, 'michael');
> commit;
> select * from student;
> EOF

所以目前这只是一个sqlplus端的强化功能，并非标准，不同数据库需要确认相应的功能是否存在。


小结


Oracle中使用WHENEVER SQLERROR进行出错控制是否继续，本文给出的例子非常简单，详细功能的使用可根据文中列出的Usage进行自行验证和探索。
