更改包含数据数组

Question

我的表格列中包含以下类型的数据：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，找到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:')

您可以将其置于更新中：

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