   Hi @lightyear007, There are two possible behavior for none-values hint strategy.
   
   1. If the tables in your SQL is not a sharding table( which means you do not configure it in shardingRule), the SQL will be routed to your defaultDatasource. What's more, the defaultDatasource also miss, the SQL will be routed to one random datasource.
   2. If the tables in your SQL is a sharding table, the SQL will be full-routed to all dataNodes you configured.
