Attachment code user post cleanup

[PiotrGT]

Hello Guys,

Can you please help me come up with a sql query which will delete this sort of content from all user posts (entire forum)?

For example: http://granturismo.pl/vb5/forum/%C5%...ia-czester2000

So basicly we need something that will find and delete content with the following data in it:
[attachment=**********]****[/attachment:********]

I did a upgrade from phpbb3 and I would like to clean up this mess. I made all of the attachments show up as images and im unable to include them as inline images them so I want to remove all of it and keep all of my attachments at the bottom of my posts (the basic/typical way).
