當我對實際數據嘗試了以下查詢時，它返回的記錄數更多。請幫助解決此問題。使用SYS_CONNECT_BY_PATH的Oracle累計計數

下面是表DM_TEMP_SUMMING_DVC_BY_FW實際數據

，我已執行查詢：

SELECT SYS_CONNECT_BY_PATH(firmware_version, '/') path_, 
    firmware_version, 
    device_count, 
    dmc_id, 
    charging_group_id , 
    IMAGE_PREREQUISITE, 
    (SELECT SUM(device_count) 
    FROM DM_TEMP_SUMMING_DVC_BY_FW t2 
    START WITH t1.firmware_version   =t2.firmware_version 
    CONNECT BY nocycle PRIOR firmware_version=image_prerequisite 
) sum_device 
FROM DM_TEMP_SUMMING_DVC_BY_FW t1 
    START WITH image_prerequisite   IS NULL 
    CONNECT BY nocycle PRIOR firmware_version =image_prerequisite

實際返回的結果：

我試圖使用查詢來生成基於firmware_version和image_prerequisite的鏈，但它沒有按預期返回結果。此查詢返回更多的記錄。

查詢中有CHARGING_GROUP_ID列，但表中沒有這樣的列。 – krokodilko

@ASaraf，是爲你工作還是不是？如果是，請將答案標記爲已接受（就像在stackoverflow.com上的常見行爲一樣）。 – nop77svk

單獨與試錯在你的SQL小提琴樣本數據，這是查詢返回的預期數據：

SELECT SYS_CONNECT_BY_PATH(firmware_version, '/') path_, 
    firmware_version, 
    device_count, 
    dmc_id, 
    charging_group_id, 
    IMAGE_PREREQUISITE, 
    (SELECT SUM(device_count) 
    FROM DM_TEMP_SUMMING_DVC_BY_FW t2 
    START WITH t1.firmware_version = t2.firmware_version 
     and T1.dmc_id = T2.dmc_id 
     and T1.charging_group_id = T2.charging_group_id 
    CONNECT BY nocycle PRIOR firmware_version=image_prerequisite and prior dmc_id = dmc_id and prior charging_group_id = charging_group_id 
) sum_device 
FROM DM_TEMP_SUMMING_DVC_BY_FW t1 
START WITH image_prerequisite IS NULL 
CONNECT BY nocycle PRIOR firmware_version = image_prerequisite 
    and prior dmc_id = dmc_id 
    and prior charging_group_id = charging_group_id

注意：是的，charging_group_id和dmc_id是非常重要的你的預期的結果，正如krokodilko在他上面的評論中正確提到的那樣。
