Question

How can i do the following :

In my WordPress website, i want to replace something in the post content

All instances of :
http://play.videolog.tv/videos/xx/xx/yyyyyy.flv

Replace with :
[videolog]yyyyyy[/videolog]

xx can be 2 or 3 digits, but yyyyyy is always 6 numbers.

Example :

http://play.videolog.tv/videos/93/80/398682.flv to [videolog]398682[/videolog]

Answer 1

Update:

update MyTable
set MyColumn = concat('[videolog]', replace(SUBSTRING(SUBSTRING_INDEX(MyColumn, '/', -1), 2), '.flv', '[/videolog]'))
where MyColumn like 'http://play.videolog.tv/videos/%'
