Ok, maybe form one once but without the column name , it's possible?
I don't think so, you need something to identify by for example:
Code:
SELECT * FROM post WHERE pagetext LIKE "%http://forums%"
Into English:
Show all posts where the message contains http://forums
^ However you must be careful, if you then try to modify i.e. remove, replace the snippet is it affecting other posted URL's or Links? Basically you need to be very careful when executing SQL Queries and if you could tell us more, why your wanting to find http://forums and remove it, the reasoning per say we might be able to assist better .
