我在更新正则表达式时遇到问题。你看我正在尝试更新:
<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4171707071707271787378757801232e393800207824202d0078757824333728222475786f222e2c" rel="noreferrer noopener nofollow">[email protected]</a>
<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="32000303020301020b000b000172504a5d561c515d5f" rel="noreferrer noopener nofollow">[email protected]</a>

我想看到这样的结果:
<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d3e3e2e2e3e2e0e3eae1eae7ea93b1bcabaafdb0bcbe" rel="noreferrer noopener nofollow">[email protected]</a>

我已经尝试过像这样的更新过程，但它根本不起作用。
update dbo.boxy_Membership
set Email like =('%[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]
[0-9]@boxy.com%')
where Email like('%[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]@%')
and Email not like ('%@boxy.com')
最佳答案
您可以通过字符串操作设置Email值:
update dbo.boxy_Membership
set Email = LEFT(Email,CHARINDEX('@',Email)-1)+'boxy.com'
where Email LIKE '%[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]@%'
and Email not like ('%@boxy.com')
如果 @ 之前的位数不变，但基于您不清楚的 WHERE 标准，则可以进一步简化:
update dbo.boxy_Membership
set Email = LEFT(Email,12)+'boxy.com'
where Email LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]@%'
and Email not like ('%@boxy.com')
