## Bug Report
I have tested some SQL between older and newest version , and found some
SQL parsing errors but work wells before.
### Which version of ShardingSphere did you use?
- **Older version**
5.0.0-RC1 ( 2020-10-26T16 master)
- **Newest version**
5.0.0-RC1 ( 2020-10-30T15 master)
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
parse correct
### Actual behavior
parse error
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
- **Results in 5.0.0.RC1-older and 5.0.0.RC1-newest**
```

customer.status = 3|
ShardingProxy(5.0.0.RC1-newest)No Sharding

customer, customer_email from customer , customer_email where customer.status =
3;

```
- **5.0.0-RC1 config**
```yaml

```
- **SQL for creating tables**
create before shardingsphere start
```sql
-- @title:deleteMultiTable,hasShardingKey:none
delete customer, customer_email from customer , customer_email where
customer.status = 3;
-- @title:selectIntoVarAfterFrom,hasShardingKey:none
select * from customer into @myvar;
