   @lwtdev Every time I see your issue, I guess there may be a bug likely. :-) Believe me, you are definitely a good QA engineer. 😃 
   Back to this issue, `no sharding schema` you mentioned means `defaultDataSourceName: ds_0`, doesn't it?
   We remove the `defaultDataSource` setting, which means ShardingSphere will help the user manage all the data sources. 
   In your case, does `customer` exist in any data source? That way, users do not need to configure any `defaultDataSourceName`, since ShardingSphere cache the metadata of all the tables (non-sharding tables included).
   Consequently, If you have a table `customer` in a certain data source, ShardingSphere will know its position after startup. Next, you execute `drop table customer`, it will position this table and run your SQL.
   
   What do you think? Welcome your feedback kindly.
   
   Best,
   Trista
