Lordeath opened a new issue #6910:
URL: https://github.com/apache/shardingsphere/issues/6910
exception was thrown when i excute this SQL:
`select a.XXX from ( select '1' as 'XXX' from dual ) a
where a.XXX = 1
`
Its just an example, my bussiness situation is something like this
### this worked in 4.0.1 but not in 4.1.1
the exception message is: Can not find owner from table.
I read the document, and I found this should be supported, so this might be
a BUG.
[https://shardingsphere.apache.org/document/current/cn/features/sharding/use-norms/sql/
](https://shardingsphere.apache.org/document/current/cn/features/sharding/use-norms/sql/
)`SELECT subquery_alias.col1 FROM (select tbl_name.col1 from tbl_name where
tbl_name.col2=?) subquery_alias
`
here is the error trace:
```
### The error occurred while setting parameters
### SQL: select a.XXX from ( select '1' as 'XXX' from dual
) a where a.XXX = 1
### Cause: java.lang.IllegalStateException: Can not find owner from table.
