SQL Server Replace Command with WIldcard
提问by CaptHowdy
I am in need of some help. Thanks to fellow user davids, I was able to get certain things working within SQL Server and am in need of some more help. Here is what I am trying to do:
我需要一些帮助。感谢其他用户 davids,我能够在 SQL Server 中运行某些东西,并且需要更多帮助。这是我想要做的:
UPDATE Table1 SET keyfield=(REPLACE(REPLACE(Column1,'http://*/folder/',''),'.avi',''))
UPDATE Table2 SET keyfield=(REPLACE(REPLACE(Column2,'http://server2/folder/',''),'.mpg',''))
Can anyone help me out or point me in the right direction to get the wildcard to work? This particular column, the * is an IP Address and it will change all the time. Granted I will know the IP's ahead of time and can probably do it one by one, but I would prefer to have it automatically replace. Thanks in advance!
任何人都可以帮助我或指出正确的方向以使通配符起作用吗?这个特定的列,* 是一个 IP 地址,它会一直改变。当然,我会提前知道 IP 并且可能可以一一完成,但我更愿意让它自动替换。提前致谢!

You should look into regular expressions.
你应该研究正则表达式。
