   ## Question

   But i can't follow what it exactly means.
   
   Can shardingsphere 5.0.0 beta version support joining tables per from 
different db?
   
   For example, a from db1，b from db2，maybe a,b have sharding rules(not 
important here).
   select a.name, b.name
   from a,b 
   where a.bid = b.id
   and a.name like "%xxx%";
