在mysql中搜索用空值替换空格

Question

I need a query to search phone number. Simple searching is fine, but I have the following condition.

eg : I want to search a number   : 0431248892

But the data can be stored in any format in database as users enter it.

Eg :

 04 3124 8892
             0431248892
         0431 2488 92
