how to count the same value twice in query

Question

the result am getting from this query below is obviously one file, this one file has just rur in whataver column, I want to have two entries with the same file, i am interested in having that counted twice. filename size type(this is an enum) ABC 10mb rur,way

        select filename,,size,type, (case when type like '%rur%' then 'rurroad' when type like '%way%' then 'hway' end) as whatever 
        from files as f,metadata as v where f.id = v.id 
        and filename like 'ANC'
        and type like '%rur%'

my result is

         filename   size    type(this is an enum)       whatever
         ABC    10 mb     rur,way                          rur

i want to get

         filename   size    type(this is an enum)       whatever
         ABC    10 mb     rur,way                          rur
         ABC    10 mb     rur,way                          way

at the same time, my file has size and usually I want to know how many MB do I have with rur, and how many with way. I want to create a pivot table summary thats why I want them all in one view/table. so i want to also get the size of 10mb rur and 10 mb way if possible. otherwise i can avoid counting the size that way

I want to get the result as i have 30% rur 20% way and xx% null

Just use an UNION :

select filename, size, type, (case when type like '%rur%' then 'rurroad' when type like '%way%' then 'hway' end) as whatever 
    from files as f, metadata as v where f.id = v.id 
    and filename like 'ANC'
    and type like '%rur%'

union all

select filename, size, type, (case when type like '%rur%' then 'rurroad' when type like '%way%' then 'hway' end) as whatever 
    from files as f, metadata as v where f.id = v.id 
    and filename like 'ANC'
    and type like '%way%' -- here we select %way% records - records with "rur,way" will appear in both queries.

PS: unless MySQL does not support it. Not sure, but my guess is that it does, it's ANSI SQL after all. PPS: it does .
