   ShardingSphere can support literal sharding-key conditions explicitly. 
Implicit semantic conditions are not in our current scope (other query 
optimizations too). 
   So we can discuss about how to go further for it. And if you are insterested 
in this topic, making an investigation and some proposals here is welcome. 
   
   In your case above, my suggestion is to modify your sql:
   1. Use sharding-key literally with `... b.col = 123`
   2.  Or split two sql, query from a with 123, and then query from b with 
sharding-key
