[英]The ALTER TABLE statement conflicted with the FOREIGN KEY constraint sql
[英]SQL Alter table Statement for columns containing data array
我的表的列具有以下类型的数据:列名“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>
我需要一个找到href="http
并将其更改为 https 的 sql 语句。
你会使用replace()
,我认为:
select replace(html_data, 'href="http:', 'href='https:')
你可以把它放在更新中:
update t
set html_data = replace(html_data, 'href="http:', 'href='https:');
