Oracle關於Group by合計、小計的使用

阿新 • • 發佈：2019-01-14

方法：group by rollup(col1,col2)

group by cube(col1,col2)

具體例子：

 select G_GOODS_OUT.DEPTID,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '01', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_01,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '02', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_02,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '03', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_03,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '04', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_04,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '05', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_05,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '06', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_06,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '07', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_07,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '08', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_08,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '09', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_09,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '10', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_10,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '11', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_11,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '12', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_12,
  sum(G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE) YEAR_SUM
  from G_GOODS_OUT
  inner join G_GOODS ON G_GOODS.ID=G_GOODS_OUT.GOODS_ID
  where 1=1 and (G_GOODS_OUT.ACTDATE>=to_date('2013-01-01 00:00:01','yyyy-MM-dd hh24:mi:ss') and G_GOODS_OUT.ACTDATE<=to_date('2013-12-31 23:59:59','yyyy-MM-dd hh24:mi:ss'))
  group by ROLLUP(G_GOODS_OUT.DEPTID)

統計結果：

部門ID	一月	二月	三月	四月	五月	六月	七月	八月	九月	十月	十一月	十二月	合計
1	1	2	3	4	5	6	7	8	9	10	11	12	78
1	2	3	4	5	6	7	8	9	10	11	12	78

例子2：

select G_GOODS_OUT.DEPTID,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '01', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_01,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '02', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_02,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '03', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_03,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '04', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_04,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '05', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_05,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '06', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_06,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '07', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_07,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '08', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_08,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '09', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_09,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '10', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_10,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '11', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_11,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '12', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_12,
  sum(G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE) YEAR_SUM
  from G_GOODS_OUT
  inner join G_GOODS ON G_GOODS.ID=G_GOODS_OUT.GOODS_ID
  where 1=1 and (G_GOODS_OUT.ACTDATE>=to_date('2013-01-01 00:00:01','yyyy-MM-dd hh24:mi:ss') and G_GOODS_OUT.ACTDATE<=to_date('2013-12-31 23:59:59','yyyy-MM-dd hh24:mi:ss'))
  group by CUBE(G_GOODS_OUT.DEPTID)

結果與上述的相似

例子：關於grouping的使用

select (case when grouping(G_GOODS_OUT.DEPTID)=1 then '合計' else cast(G_GOODS_OUT.DEPTID as varchar(20)) end ) DEPTID,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '01', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_01,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '02', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_02,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '03', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_03,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '04', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_04,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '05', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_05,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '06', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_06,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '07', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_07,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '08', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_08,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '09', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_09,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '10', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_10,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '11', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_11,
  sum(decode(to_char(G_GOODS_OUT.ACTDATE,'MM'), '12', G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE,null)) as MONTH_12,
  sum(G_GOODS_OUT.SQNUM*G_GOODS.U_PRICE) YEAR_SUM
  from G_GOODS_OUT
  inner join G_GOODS ON G_GOODS.ID=G_GOODS_OUT.GOODS_ID
  where 1=1 and (G_GOODS_OUT.ACTDATE>=to_date('2013-01-01 00:00:01','yyyy-MM-dd hh24:mi:ss') and G_GOODS_OUT.ACTDATE<=to_date('2013-12-31 23:59:59','yyyy-MM-dd hh24:mi:ss'))
  group by CUBE(G_GOODS_OUT.DEPTID)

結果為：

部門ID	一月	二月	三月	四月	五月	六月	七月	八月	九月	十月	十一月	十二月	合計
1	1	2	3	4	5	6	7	8	9	10	11	12	78
合計	1	2	3	4	5	6	7	8	9	10	11	12	78

grouping(col1)的結果為1表示是合計結果，否則是普通聚合結果

注：其實sql Server也是支援group by rollup與group by cube 語法的
