甲骨文的SQL查詢與內部聯接涉及和值

Question

SELECT sc.TAAC_SHARE_CLASS_ID, 
    SCS.SHARE_CLASS_SID, 
    SCS.REPORTING_DT, 
    SCS.SHARE_CLASS_SNAPSHOT_SID, 
    SCS.DIST_UNMOD_30_DAY_YIELD_PCT, 
    SCS.DER_DIST_12_MO_YIELD_PCT, 
    SCS.DER_SEC_30_DAY_YIELD_PCT AS SCS_DER_SEC_30_DAY_YIELD_PCT, 
    SCS.DER_SEC_RESTATED_YIELD_PCT AS SCS_DER_SEC_RESTATED_YIELD_PCT 
    FROM SHARE_CLASS sc 
    INNER JOIN PORTFOLIO P ON (P.PORTFOLIO_SID=SC.PORTFOLIO_SID) 
    INNER JOIN SHARE_CLASS_SNAPSHOT SCS ON 
    (SCS.SHARE_CLASS_SID=sc.SHARE_CLASS_SID) 
    WHERE SCS.REPORTING_DT = '24-JUL-17' AND P.PORTFOLIO_ID = 638; 

我跑這個查詢，並得到了以下的輸出：image

在這裏，而不是讓不同的行爲同一TAAC_SHARE_CLASS_ID，我想合併的輸出相同的TAAC_SHARE_CLASS_ID。

例如，第一行與TAAC_SHARE_CLASS_ID = 000648應該具有的值對於所有的4列：

SCS.DIST_UNMOD_30_DAY_YIELD_PCT, 
SCS.DER_DIST_12_MO_YIELD_PCT, 
SCS.DER_SEC_30_DAY_YIELD_PCT, 
SCS.DER_SEC_RESTATED_YIELD_PCT. 

因此，第一行應具有這些列值作爲2.96,3.2972596，7541.085263433，7550

我輸出的最後4行並不是真正需要的，因爲我們現在已經將這些數據合併到前4行中。

我該如何改變這個查詢來實現相同？請幫忙。

我建議你組你的結果通過TAAC_SHARE_CLASS_ID列，MAX（）其餘的列，這樣的事情：

SELECT sc.TAAC_SHARE_CLASS_ID, 
     max(SCS.SHARE_CLASS_SID) as SHARE_CLASS_SID, 
     max(SCS.REPORTING_DT) as REPORTING_DT, 
     max(SCS.SHARE_CLASS_SNAPSHOT_SID) as SHARE_CLASS_SNAPSHOT_SID, 
     max(SCS.DIST_UNMOD_30_DAY_YIELD_PCT) as DIST_UNMOD_30_DAY_YIELD_PCT, 
     max(SCS.DER_DIST_12_MO_YIELD_PCT) as DER_DIST_12_MO_YIELD_PCT, 
     max(SCS.DER_SEC_30_DAY_YIELD_PCT) AS SCS_DER_SEC_30_DAY_YIELD_PCT, 
     max(SCS.DER_SEC_RESTATED_YIELD_PCT) AS SCS_DER_SEC_RESTATED_YIELD_PCT 
FROM SHARE_CLASS sc 
INNER JOIN PORTFOLIO P ON (P.PORTFOLIO_SID=SC.PORTFOLIO_SID) 
INNER JOIN SHARE_CLASS_SNAPSHOT SCS ON (SCS.SHARE_CLASS_SID=sc.SHARE_CLASS_SID) 
WHERE SCS.REPORTING_DT = '24-JUL-17' AND P.PORTFOLIO_ID = 638 
GROUP BY sc.TAAC_SHARE_CLASS_ID;
