   1. I did not create any tables; 
   In fact , the sql i want to execute is ``` sctl:explain select * from customer where id = 3;```
   And It's also cause a exception
   2. Thanks for your patient to figure out this problem 
   The right config of `database_inline`should be
   ```yaml
       database_inline:
         type: INLINE
         props:
           algorithm-expression: ds_0${(id % 4 ).intdiv(2)}
   ```
