wgy8283335 opened a new issue #12581:
URL: https://github.com/apache/shardingsphere/issues/12581
## Feature Request
### Describe the feature you would like.
SqlNodeConvertEngine.convert() can not parse SQL with subquery correctly.
So, we should add some logic when processing the subquery.
SqlNodeConverter in
'org.apache.shardingsphere.infra.optimize.core.convert.converter' could not
parse subquery.
For example:
SELECT_SQL_SUBQUERY_WHERE_EXISTS =
"SELECT t_order_federate.order_id, t_order_federate.user_id "
+ "FROM t_order_federate "
+ "WHERE EXISTS (SELECT * FROM t_user_info WHERE
t_order_federate.user_id = t_user_info.user_id)";
SELECT_SQL_SUBQUERY_FROM =
"SELECT t_order_federate.order_id, t_order_federate.user_id,
u.user_id "
+ "FROM t_order_federate, (SELECT * FROM t_user_info) as
u "
+ "WHERE t_order_federate.user_id = u.user_id ";
