   Hi @linghengqian , I'm not sure what's wrong for now, looks there's a mistake?
   `tb_result3_sharding_sphere_$->{0..366}` means there're `367` shards, seems not match `autoTablesAmount = 366`.
   
   Could you debug and set breakpoint on `OrderByValue.getOrderValuesCaseSensitiveFromTables`, when NPE thrown, verify:
   - is `tableMetaData` null? If it's true, why `schema.get(tableName)` return null?
   - what's `tableName` value
   
   And could you supply a demo (and create table sql) to reproduce this issue?
