头行保存在实用中经常用到,头行保存指的是头表和行表(一对多)的数据同时插入,如中途失败则这次事务不进行提交。
假设我们有两张表
<style>
table th:first-of-type {
width: 100px;
}
</style>
**hls_person(头表)**
pid | name | age |
-------- | ----- | -----|
1|张三|21
2|李四|36
*hls_hobby(行表)*
*
hid | pid |hobby| cause|
-------- | -----|----- |-----|
1|1|篮球| 因为篮球好玩
2|1|游泳| 因为游泳好玩
3|1|动画片|最爱看大头儿子
4|2|画画|梵高的画也不过如此

需求是新增一个人的信息以及它的爱好(向hls_person和hls_hobby表新增记录)
