Answer 1

我看到你的另一个帖子。不能 100% 确定您要做什么，但您可能需要考虑使用诸如 ratio_to_report 之类的 Windows 函数。请参见下面的示例。这是windows函数的链接

select 
        store_id, profit, 
        100 * ratio_to_report(profit) over () as percent_profit
    from store_profit
    order by store_id;
+----------+--------+----------------+
| STORE_ID | PROFIT | PERCENT_PROFIT |
|----------+--------+----------------|
|        1 | 300.00 |    30.00000000 |
|        2 | 250.00 |    25.00000000 |
|        3 | 450.00 |    45.00000000 |
|        4 |   NULL |           NULL |
