在这里插入图片描述
通过sqlplus可以连接数据库根据用户权限进行数据或者设定操作，但是需要交互操作并返回结果，这篇文章介绍一下如何在程序中使用sqlplus。

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：

Here Document

因为sqlplus是控制台的方式与用户进行交互式的输入/输出对应，而在程序执行的过程中显然是需要预先定好的输入，这样可以考虑使用Here Document，比如希望通过sqlplus来确认数据库版本信息，则可以这样

# sqlplus system/liumiao123 <<EOF
> select * from v\$version;
> EOF

注意：需要注意v$version中的$需要转义

创建table

接下来使用Here Document的方式调用sqlplus来创建table

# sqlplus system/liumiao123 <<EOF
> create table student (
> stuid  number(4),
> stuname varchar2(50),
> primary key (stuid)
> );
> desc student;
> EOF
