特定日期的匯率

Question

我正在創建下面顯示的查詢，該查詢返回索賠文件的付款/准備金金額。 這個想法是在指定的日期 exch_r."AtDate" 轉換為本地貨幣作為儲備。 但是，結果返回的是金額的總和（以歐元為單位），而不是以 Lei 為單位的值的總和。

例如：有 3 歐元儲備金（200 歐元；9 歐元；56 歐元），1 歐元儲備金（110 雷伊）。

返回的結果是 265 EUR * 4,8567 LEI = 1.287,0255 LEI，無需在轉換后添加 110 Lei。 我的結果應該是 1.287,0255 + 110 LEI = 1.397,0255

select d."DAMFileNr", plata_lei
,coalesce(SUM(CASE WHEN d_rez."EID"='10' THEN d_rez."RDAM" ELSE 
           d_rez."RDAM"*exch_r."EXCValue" END),0) as rez_lei
from "DAM" as d
left join "DAMRez" as d_Rez on d."Index"=d_rez."DID"
left join lateral (
    select coalesce(sum(case when d_pay."EID"='10' then d_pay."PAYVal" else
                                d_pay."PAYVal"*exch_p."EXCValue" end),0) as plata_lei
    from "DAMPay" as d_pay
    LEFT JOIN "EXCValues" exch_p ON exch_p."AtDate"=d_pay."PAYDate" and exch_p."EID"=d_pay."EID"
    where d."Index" = d_pay."DID"
) d_pay on true
LEFT JOIN "EXCValues" exch_r ON exch_r."EID"=d_rez."EID"
where exch_r."AtDate"='2020-09-16' and d."DAMFileNr" like 'S/SC/05/2020'
group by d."DAMFileNr", plata_lei
order by d."DAMFileNr"

你能告訴我如何處理這個問題嗎？ 謝謝

解決了。 我添加了一個新條件： where (d_rez."EID"='10' or exch_r."AtDate"='2020-09-16') 和 d."DAMFileNr" like 'S/SC/05/2020'
