問題：
開發一個關於各煙葉等級的二次驗級的原發件數、原發重量及驗收重量的統計報表。其中，原發件數、原發重量和驗收重量等列要求計算出各等級組別的小計和所有記錄的合計。
語句：
SELECT DECODE(GROUPING(T4.TOBACCO_CLASS_TYPE) + GROUPING(T1.TOBACCO_CLASS_NAME),
1,
DECODE(T4.TOBACCO_TYPE,
51, ‘上等煙小計’,
52, ‘中等煙小計’,
53, ‘下等煙小計’,
54, ‘低等煙小計’,
‘小計’),

NVL(SUM(T1.ORG_WEIGHT), 0) TOTAL_ORG_WEIGHT,
NVL(SUM(T1.AMOUNT), 0) TOTAL_AMOUNT
FROM VI_FK_BALANCE_DETAIL T1, TB_TOBACCO_CLASS T4
WHERE T1.TOBACCO_CLASS_ID=T4.TOBACCO_CLASS_ID
AND T1.ACCOUNT_YEAR=T4.ACCOUNT_YEAR
AND T4.DEL_FLAG=0
AND T4.ENABLE_FLAG=0
AND T1.REC_DATE > TO_DATE(‘2006-11-05’, ‘YYYY-MM-DD’
GROUP BY ROLLUP( T4.TOBACCO_CLASS_TYPE,T1.TOBACCO_CLASS_NAME)
ORDER BY T4.TOBACCO_CLASS_TYPE
通過查詢得到統計結果如下表所示，該表的統計結果已經滿足了統計要求。
