mysql - SQL Alter table 语句包含数据数组的列

Question

我的表的列具有以下类型的数据:列名称“html_data”:

 <h2 class="blue">Safely does it</h2>
<p>Contemplating a dive off your hotel balcony into the pool? Planning to hop onto a 
<a href="http://">moped in Bali</a> y risks. Before leaping off into the abyss, check, do you have travel insurance? And if so, would you be covered for <a href="http">?</a></p>
<h2 class="green">Respect the relics</h2>

我需要一个 sql 语句来查找 href="http 并将其更改为 https。

Answer 1

我认为你会使用replace():

select replace(html_data, 'href="http:', 'href='https:')

您可以将其放入更新中:

update t
    set html_data = replace(html_data, 'href="http:', 'href='https:');
