Oracle SQL Where Case Error

我有這個查詢，我試圖運行，問題是我不斷收到「缺少關鍵字」notifactions。我試圖生成一個查詢，將計算系統日期對代數calcualted值，如果他們相等，那麼Where語句將根據我的情況下「THEN」部分後的值進行搜索。有人可以幫助這些嗎？Oracle SQL Where Case Error

WHERE 
    CASE

我想你應該做子查詢來選擇你正在尋找的值，然後在主查詢中執行WHERE語句。例如：

SELECT * FROM suppliers WHERE office_name = (
SELECT 
CASE 
    WHEN supplier_name = 'IBM' and supplier_type = 'Hardware' THEN 'North office' 
    WHEN supplier_name = 'IBM' and supplier_type = 'Software' THEN 'South office' 
END 
FROM suppliers; 
);

您必須將總體案例表達式結果與某些內容進行比較，但不能在每個then內進行比較。你也有你的報價搞砸了，這無助於理解你在做什麼。但它看起來像你想要更多的東西一樣：

WHERE 
    THE.DESCRIPTION = CASE 
    WHEN (SYSDATE) = (42192+30*(TRUNC((((SYSDATE)*52)/365)/4) - (((42192*52)/365)/4))) THEN 'TEST-01' 
    WHEN (SYSDATE) = (42193+30*(TRUNC((((SYSDATE)*52)/365)/4) - (((42193*52)/365)/4))) THEN 'TEST-02' 
    ... 
    END

雖然我會扭轉when計算所以你最終檢查的東西要簡單得多;自sysdate*52isn't going to work我真的不知道如何解開那部分。
