Question

这是我的表格的样子

id | amount |     Consider table name as Amount
--------------
1  | 100
2  | 100
3  | 100
4  | 200
5  | 300
6  | 300

我想写一个查询，它返回我的范围计数：

amount | count
---------------
100    | 3
200    | 1
300    | 2

请帮帮我，我被困了！

EDIT1：我想输入金额范围！对不起，我错过了！

EDIT2：我可以传递多个范围，例如100到200,200到300，只有100

Answer 1

SELECT amount,COUNT(amount)as count FROM table 
GROUP BY amount
HAVING amount BETWEEN x AND y

如果您希望使用HAVING的特定金额的群组，如果您希望使用WHERE amount个别行...

Answer 2

试试这个：

select amount,count(*)
from MyTable
where amount between 100 and 200
group by amount
order by amount

Answer 3

使用此查询：

SELECT count(id) 
FROM Amount 
GROUP BY amount;

Answer 4

如果我理解正确，你想要这样的范围吗？

SELECT amount,COUNT(amount)as count
FROM table 
WHERE amount > 5 AND amount < 600
GROUP BY amount
