   meanwhile, I found that `shardingsphere` is not good compatible with the sql style with schema prefix, for example:
   
   ```sql
   DELETE FROM t_order WHERE order_id IN (1);
   ```
   is ok, but
   ```sql
   DELETE FROM `t_order` WHERE `t_order`.`order_id` IN (1);
   ```
   is not work with the follow error:
   ```java
   org.apache.shardingsphere.underlying.common.exception.ShardingSphereException: Cannot support Multiple-Table for 'org.apache.shardingsphere.sql.parser.sql.statement.dml.DeleteStatement@3293c2dc'.
