做另一張表的統計,比如本部門有多少在職人員。本崗位有多少女生。
有兩個表,分別存放了【操作員】和【單據】,要根據單據的不同類型來分類彙總(銷售單、銷售退貨單,筆數和金額),並且顯示在同一張表裏,不想用做兩次查詢再合併的方法,研究了一下,終於搞定:
d_employee表
d_bilndx表
代碼如下:
select b.inputid as 開單員編號, e.fullname as 開單員, isnull( ( select count(*) from d_bilndx where draft=3 and biltype=12 and d_bilndx.inputid=e.id ), 0) as '銷售開單筆數', isnull( ( select sum(d_bilndx.amount) from d_bilndx where draft=3 and biltype=12 and d_bilndx.inputid=e.id ), 0) as '銷售開單金額', isnull( ( select count(*) from d_bilndx where draft=3 and biltype=13 and d_bilndx.inputid=e.id ), 0) as '銷售退單筆數', isnull( ( select sum(d_bilndx.amount) from d_bilndx where draft=3 and biltype=13 and d_bilndx.inputid=e.id ), 0) as '銷售退單金額', count(b.biltype) as 開單總筆數, sum(b.Amount) as 開單金額 from d_bilndx as b left join d_employee as e on b.inputid=e.id where b.draft=3 and ( b.biltype=12 or b.biltype=13 ) group by b.inputid, e.fullname, e.id
得到結果:
補記:以上代碼有一個問題,就是如果沒有符合條件的單據,查到的結果爲空,而我們可能希望,查不到符合條件的記錄,相關字段要顯示爲0(並且按天來統計),改寫代碼如下:
select e1.id as ePersonCode, e1.FullName as eFullName, isnull(Bill_Sale_NUm, 0) as Bill_Sale_Num, isnull(Bill_Sale_Amount, 0) as Bill_Sale_Amount, isnull(Bill_SaleReturn_Num, 0) as Bill_SaleReturn_Num, isnull(Bill_SaleReturn_Amount, 0) as Bill_SaleReturn_Amount from d_employee as e1 left join ( select b.inputid as ePersonCode, e.fullname as eFullName, isnull( ( select count(*) from d_bilndx where biltype=12 and d_bilndx.inputid=e.id and d_bilndx.date>='2018-06-03' and d_bilndx.date<='2018-06-03' ), 0) as Bill_Sale_Num, isnull( ( select sum(d_bilndx.amount) from d_bilndx where biltype=12 and d_bilndx.inputid=e.id and d_bilndx.date>='2018-06-03' and d_bilndx.date<='2018-06-03' ), 0) as Bill_Sale_Amount, isnull( ( select count(*) from d_bilndx where biltype=13 and d_bilndx.inputid=e.id and d_bilndx.date>='2018-06-03' and d_bilndx.date<='2018-06-03' ), 0) as Bill_SaleReturn_Num, isnull( ( select sum(d_bilndx.amount) from d_bilndx where biltype=13 and d_bilndx.inputid=e.id and d_bilndx.date>='2018-06-03' and d_bilndx.date<='2018-06-03' ), 0) as Bill_SaleReturn_Amount, count(b.biltype) as Bill_Total_Num from d_employee as e left join d_bilndx as b on b.inputid=e.id where (b.draft=3 or b.draft=2) and ( b.biltype=12 or b.biltype=13 ) and b.date>='2018-06-03' and b.date<='2018-06-03' group by b.inputid, e.fullname, e.id ) as t1 on e1.id = t1.ePersonCode where e1.id<>'00000' order by ePersonCode asc
得到結果如下:
