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 tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
