> According to the description provided by Jira, we need to add a Distinct at the top level of the Project, and perhaps we can also add test cases to JdbcTest to ensure that our transformation implementation is correct. The SQL example: > > ``` > select * from (values (1, 2), (1, 2), (3, 4), (5, 7)) as t(a, b) > intersect > select * from (values (1, 2), (3, 4), (5, 6)) as t(a, b) ; > ``` > > You will know why we need the Distinct. @NobiGo Thanks, I got it, I will update it. -- This is an automated message from the Apache Git Service.
