php - MySQL wildcard return only matches with hyphen and number -


I have the following lines in my database, which is a duplicate if it increases:

foo < Br> F-1
F-2
F-3
Bar
Bar-1 < / P>

I want to ask DB and want to get previous F - # . I've tried to use the operator like below: 

  Select * Link where '$ slug%' object timestamp DESC limit1 ";   < P>  my problem  if $ slug == f gives foo-3 instead of f-3. Is there a better way to use% wildcard?   < P> 
 
  select link * Where '$ slug-%' or slug = '$ slug' order timestamp DESC limit 1   
 option, if you do not have  or  If you want to do this, you will need to use a  REGEXP  match. However, you probably leave the ability to use the index for the query if you do this.

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part.

Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
