この記事では、Asp.net 管理情報システムのデータ統計機能の実装方法を主に紹介します。必要な方は参考にしてください。
データ統計は、職場のリーダーに統計データを報告するときに不可欠な機能です。進捗データが必要な場合に便利です。私の意見では、統計モジュールは次の機能を実装する必要があります:
実際の環境とアプリケーションでの実装は次のとおりです:
まず、データベース内にテーブル値関数を構築します。この関数は、さまざまな時間カットオフに従ってデータを返すことができ、テーブルはビューとしても機能し、パラメーター テーブルの値は戻り結果に直接含まれます。
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) )
を使用して、8 月 25 日の期限のデータをクエリできます。
次のステップはインターフェイスの設計です。jquery-ui の Dropabledragable コントロールを使用します。フィールドはインターフェイス上に配置されており、統計を実行するために対応するフィールドに直接ドラッグできます。
グループ化フィールドに加えて、表示フィールドは特定の値に基づいて統計フィルタリングを実行することもでき、複数のグループ化統計の機能を果たします。
select * from [get...]('2016-8-25')
ご覧のとおり、一番上の列はデータフィルタリングで、その後にシステムによって保存されたクエリがあります(テーブルクエリとグラフィッククエリに分かれています)。保存されたクエリをクリックして直接取得します。クエリ結果を表示することも、保存されたクエリを削除することもできます。以下はカスタム クエリ、上は条件の行、そしてフィールドをグループ化列にドラッグすると、フィールド名が表示列に表示され、特定の値が表示されます。表示されたデータの統計をグループ化してフィルタリングすることもできます。以下に、小計と合計を表示するかどうか、グラフの表示方法など、いくつかのオプションを示します。
統計を表形式で表示します。ポップアップ ボックスの各値をクリックすると、下部にクエリ条件が保存され、グラフィカルに表示されることがわかります:

将来のバージョンで作成される予定の機能:
統計フィールドのさらなる最適化、および複数の条件の組み合わせを使用して同じフィールドをフィルター処理する機能 これは比較的単純で、次のクラスを拡張するだけです。 UIを調整します。
