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 root@172.58.1.1: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 root@172.58.1.1:db1> select distinct a, max(a) over() from t; +---+---------------+ | a | max(a) over() | +---+---------------+ | 1 | 1 | +---+---------------+ ```
