SQL trim wildcard pattern

Question

I have a quite large MySQL db table (posts) and in one field (post_text) there are a lot of old BB code that needs trimming.

This is one example of what i need to find: quote:1270ae936b (after : characters varies, always 10)

And replace with: quote:

How do i do this in SQL command?

Thanks in advance! :)

Not tested but logically it should work for you. check more about specific range of characters at http://dev.mysql.com/doc/refman/5.7/en/pattern-matching.html

Test Query:

//run it before update query
 SELECT post_text FROM posts WHERE post_text REGEXP 'quote:[a-zA-Z0-9]{10}'; 

Main Query:

    UPDATE posts
    SET post_text = 'quote:' 
    WHERE post_text REGEXP 'quote:[a-zA-Z0-9]{10}';
