這篇文章主要介紹了Asp.net管理資訊系統中資料統計功能的實現方法,需要的朋友可以參考下
資料統計是每個系統中必備的功能，在給領導報告統計數據，工作中所需的進度數據時非常有用。
在我看來，一個統計的模組應該實現以下功能：
#能夠將常用的查詢的統計結果顯示出來；
- ##顯示的結果可以是表格形式，也可以是圖形形式，如果是圖形的話能夠以多種形式顯示（長條圖、折線圖、圓餅圖、雷達圖、堆疊長條圖等）：
- 統計查詢的結果，點選數字或百分比能夠顯示詳細的資料；
- #能夠自由組合查詢條件、篩選條件、分組條件、排序等等；
- 統計結果最好有個即時預覽；
#查詢統計能夠保存，以便下次能直接呼叫並顯示統計查詢的結果；
對於已儲存後的查詢統計，下次呼叫時也可以依照靈活的篩選手段對查詢結果進行篩選；
對於一些複雜的查詢，能夠直接在後台寫Sql或者調用Sp出數據
......
#這是學生的就業系統，學生在不同的時期會對自己畢業去向進行登記，因此依照不同時間截點統計出來的資料是不一樣的。資料表有100多個欄位（並不是所有欄位都需要統計）。
首先，我們在資料庫中建立一個表值函數，能夠按照不同的時間截斷返回出數據，表也起到視圖的作用，將參數表的值直接包含到返回結果中去。
ALTER FUNCTION [dbo].[Get.............] ( @gxsj datetime ) RETURNS TABLE AS RETURN ( select t1.*, dbo.depacode.xymc, CASE t1.xldm WHEN '01' THEN '博士' WHEN '11' THEN '硕士' WHEN '25' THEN '双学位' WHEN '31' THEN '本科' WHEN '41' THEN '专科' WHEN '61' THEN '高职' ELSE '' END AS xlmc, CASE WHEN LEFT(t1.sydqdm, 2) IN ('11', '12', '13', '21', '31', '32', '33', '35', '37', '44', '46', '71', '81', '82') THEN '东部' WHEN LEFT(t1.sydqdm, 2) IN ('14', '22', '23', '34', '36', '41', '42', '43') THEN '中部' WHEN LEFT(t1.sydqdm, 2) IN ('15', '45', '51', '50', '52', '53', '54', '61', '62', '65', '63', '64') THEN '西部' ELSE '' END AS sydq, sydq.dwdqmc AS sysf, CASE WHEN LEFT(t1.dwdqdm, 2) IN ('11', '12', '13', '21', '31', '32', '33', '35', '37', '44', '46', '71', '81', '82') THEN '东部' WHEN LEFT(t1.dwdqdm, 2) IN ('14', '22', '23', '34', '36', '41', '42', '43') THEN '中部' WHEN LEFT(t1.dwdqdm, 2) IN ('15', '45', '51', '50', '52', '53', '54', '61', '62', '65', '63', '64') THEN '西部' ELSE '' END AS dwdq, dwdq.dwdqmc AS dwsf, dbo.Entcode.hyname, dbo.hydygx.hymldm, dbo.hydygx.hyml, CASE t1.xbdm WHEN 1 THEN '男' WHEN 2 THEN '女' ELSE '男' END AS xbmc, [mzdmb].[nation] AS mzmc, [EjByqxdmb].[Ejbyqxmc], dbo.byqxdygx.jybbyqx, t1.gn500 AS jybdwxzdm, CASE t1.knslbdm WHEN '7' THEN '就业困难、家庭困难和残疾' WHEN '6' THEN '家庭困难和残疾' WHEN '5' THEN '就业困难和残疾' WHEN '4' THEN '残疾' WHEN '3' THEN '就业和家庭困难' WHEN '2' THEN '家庭困难' WHEN '1' THEN '就业困难' ELSE '非困难生' END AS Knslb from [table] as t1 LEFT OUTER JOIN dbo.depacode ON t1.xydm = dbo.depacode.xydm LEFT OUTER JOIN dbo.dwdq AS sydq ON LEFT(t1.sydqdm, 2) + '0000' = sydq.dwdqdm LEFT OUTER JOIN dbo.dwdq AS dwdq ON LEFT(t1.dwdqdm, 2) + '0000' = dwdq.dwdqdm LEFT OUTER JOIN dbo.Entcode ON t1.hylb = dbo.Entcode.hycode LEFT OUTER JOIN dbo.hydygx ON t1.hylb = dbo.hydygx.hydldm LEFT OUTER JOIN [mzdmb] ON t1.mzdm = [mzdmb].[mzdm] LEFT OUTER JOIN [EjByqxdmb] ON t1.byqx2 = [EjByqxdmb].[Ejbyqxdm] LEFT OUTER JOIN dbo.byqxdygx ON t1.byqx = dbo.byqxdygx.shbyqx AND t1.dwxzdm = dbo.byqxdygx.shdwxzdm where [gxsj] <= dateadd(day,1,@gxsj) and HisId in (SELECT TOP 1 HisId FROM [table] WHERE [gxsj] <= dateadd(day,1,@gxsj) and xsxh = t1.xsxh and bynf = t1.bynf and t1.byqx not in ('08','05','11') ORDER BY [gxsj] DESC) )
這樣我們使用
select * from [get...]('2016-8-25')
接下來是介面設計，我們使用jequery-ui中dropable\dragable的控件，欄位排列在介面上，直接拖曳到對應域裡，就能夠進行統計。
除了分組欄位外，顯示欄位也能夠依照具體的值進行統計過濾，起到多重分組統計的功能。
大家可以看到，最上面一欄是資料篩選，然後是系統已經儲存的查詢（分成表格查詢和圖形查詢），點選已儲存好的查詢直接出查詢結果，也可以刪除已儲存的查詢。在下面是自訂查詢，上面是一排條件，然後是可以拖曳的字段，當字段拖至分組列，則顯示字段名稱；拖至顯示列，還可以對顯示的資料的具體值進行分組篩選統計。下方則是一些選項，是否顯示小計、總計，以何種方式顯示圖表。
以表格形式的顯示統計，可以看到，每個數值都可以點擊彈出框顯示詳情，最下方能夠保存查詢條件，以圖形方式顯示等：
