如何选择付款金额独特的客户

Question

如何选择付款金额（以UAH为单位）在150至400 UAH之间的唯一客户？

我有桌子：

•出生日期-交易日期；

•Transum数字（20,2）-付款金额；

•CurrencyRate数字（20.2）-货币汇率；

ID_Client Trandate  Transum CurrencyRate    Currency
1   2018.12.01  100 1   UAH
1   2018.12.02  150 2   USD
2   2018.12.01  200 1   UAH
3   2018.12.01  250 3   EUR
3   2018.12.02  300 1   UAH
3   2018.12.03  350 2   USD
7   2019.01.08  600 1   UAH

我的代码太糟糕了

SELECT DISTINCT ID_Client
,      Transum 
FROM   `Payment.TotalPayments` 
WHERE  Currency = "UAH" 
       AND Transum >= "150" 
       AND Transum <= "400"

一定是这样的：

SELECT ID_Client, COUNT(Transum)
FROM `Payment.TotalPayments`
HAVING COUNT(Transum) BETWEEN 150 AND 400

您可以在下面尝试-

export default 
  connect(
    mapStateToProps,
    mapDispatchToProps, null, {forwardRef: true})(Component)
