killxdcj opened a new issue #5583:
URL: https://github.com/apache/incubator-doris/issues/5583
Forget to copy realchildren when initializing GroupingFunctionCallExpr through the copy constructor
> public GroupingFunctionCallExpr(GroupingFunctionCallExpr other) {
> super(other);
> this.childrenReseted = other.childrenReseted;
> }
realchildren should be copy too?
> public GroupingFunctionCallExpr(GroupingFunctionCallExpr other) {
> super(other);
> this.childrenReseted = other.childrenReseted;
> if (this.childrenReseted) {
> this.realChildren = Expr.cloneList(other.realChildren);
> }
> }
NPE will throwed when run the fllowing sql
> SELECT col1,
> IF(GROUPING(`col1`) = 1, COUNT(col1), 0) AS class_count,
> col2,
> IF(GROUPING(`col2`) = 1, COUNT(col2), 0) AS school_count
> FROM test
> GROUP BY
