在連接語句中使用案例Oracle

Question

我一直在嘗試是否有可能加入兩個表。 以下是我所做的示例，但是它返回錯誤ORA-00905：缺少關鍵字。

關於如何實現的任何想法？ 謝謝。

Answer 1

您缺少的關鍵字是以下一行：

LEFT JOIN rejects r ON CASE WHEN wl.specname =  '8810_WS_VISUAL_INS_WS' THEN c.containerid = r.containerid AND lw.waferscribenumber = r.waferscribenumber
                       ELSE c.containerid = r.containerid
                       END

我建議你寫這個沒有任何case ：

LEFT JOIN rejects r
ON c.containerid = r.containerid AND
   ((wl.specname = '8810_WS_VISUAL_INS_WS' AND lw.waferscribenumber = r.waferscribenumber) OR
    ((wl.specname <> '8810_WS_VISUAL_INS_WS' OR wl.specname IS NULL)
   )

在Oracle中， case語句不能返回布爾表達式。 您可以將條件寫為：

LEFT JOIN rejects r
ON c.containerid = r.containerid AND
   (case when (wl.specname = '8810_WS_VISUAL_INS_WS' then lw.waferscribenumber
         else r.waferscribenumber
    end) = r.waferscribenumber

但是我認為第一種方法更清晰。
