In fact, using the same configuration, not only DDL but other SQL examples
are also have problem:
```sql

deleteMultiTable[hasShardingKey:all]; Support:true; SQL: delete
customer, customer_email from customer , customer_email where customer.status
= 3 and customer.id = 3 and customer_email.id = 3;
ds_0|delete customer, customer_email from customer , customer_email where
customer.status = 3 and customer.id = 3 and customer_email.id = 3|
ShardingProxy(5.0.0.RC1)No Sharding
deleteMultiTable[hasShardingKey:all]; Support:false; SQL: delete
customer, customer_email from customer , customer_email where customer.status
= 3 and customer.id = 3 and customer_email.id = 3;
java.sql.SQLException: 2Unknown exception: [Cannot support Multiple-Table
