### What problem does this PR solve? for a project, if it is distinct and no contains agg function, ProjectWithDistinctToAggregate will convert project to agg. but the agg function should exclude window function. for example: for table t: ``` create table t(a int); insert into t values (1), (1); ``` then for a distinct query ``` MySQL [email protected]:db1> select distinct a, max(a) over() from t; +---+---------------+ | a | max(a) over() | +---+---------------+ | 1 | 1 | | 1 | 1 | +---+---------------+ ``` it output two rows, it's error, should output one row. so we exclude the window function, then with this pr, the result will be: ``` MySQL [email protected]:db1> select distinct a, max(a) over() from t; +---+---------------+ | a | max(a) over() | +---+---------------+ | 1 | 1 | +---+---------------+ ``` ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
