SQL Server-Abfrage für die Organisation von Daten

Question

Ich verwende SQL Server 2012, und ich möchte diese Ansicht durch Datenbankabfrage erreichen und es programmgesteuert mit Jquery anzeigen.

Erwarteter Ausgang

Stromausgang

Dies ist meine aktuelle Abfrage:

SELECT [OrganizationName],COUNT([Id]) AS Frequency,[Set] FROM *{table}* GROUP BY [Set],[OrganizationName]; 

Und ich zeigen die Tabelle mit Ajax:

$.ajax({ 
      url: '@Url.Action("GetOrganizations", "Companies")', 
      type: 'POST', 
      contentType: 'application/json', 
      data: null, 
      dataType: 'json', 
      success: function (result) { 
       console.log("result length: " + result.length); 
       $("#orgTableDiv").css("max-height", result.length * 15); 
       if (result.length > 0 && result[0].OrganizationName!=null) 
       { 
        var selectOptions = "<option value='All'>All</option>"; // dropdown containing all organizations 
        $("#orgTable").empty(); 
        var div = ""; 

        div = "<tr>" + 
          "<th>No</th>" + 
          "<th>Organization Name</th>"; 

        for (var i=0; i<data.length ; i++) { 
         div += "<th>"+data[i]["name"]+"</th>"; 
        } 

        div += "</tr>"; 
        $("#orgTable").append(div); 

        var numOfSets = data.length; 
        var organizationName = ""; 
        var counter = 1; 

        for (var i = 0; i < result.length; i++) { 

         var row = "<tr>" + 
             "<td>" + counter + "</td>" + 
             "<td>" + result[i].OrganizationName + "</td>"; 
         if (result[i].SetValue!=null) 
          for (var j=0; j < result[i].SetValue.length; j++) { 
           var setData = result[i].SetValue[j].split(':'); 

           for (var m=0; m<setData.length; m++) { 
            var temp = setData; 
           } 

           var setNum = setData[0]; 
           var setFrequency = setData[1]; 

           for (var c=1; c<=numOfSets; c++) { 
            if (c==setNum) 
             row += "<td>" + setFrequency + "</td>"; 

           } 
          } 
         counter++; 
         row += "</tr>"; 

         $("#orgTable").append(row); 
         selectOptions +="<option value='" + result[i].OrganizationName+ "'>" + result[i].OrganizationName+ "</option>"; 
        } 

        $('#organizationOption').empty().append(selectOptions); 
       } 

      }, 
      error: function (result) { 
       alert('Error: ' + result); 
      } 
     }) 

Wie kann ich die erwartete Ausgabe erreichen? Ich bin derzeit mit meiner Implementierung festgefahren.

Answer 1

SELECT [OrganizationName], 
Sum(case when set = 1 then 1 else 0 end) as set1, 
Sum(case when set = 2 then 1 else 0 end) as set2, 
Sum(case when set = 3 then 1 else 0 end) as set3, 
Sum(case when set = 4 then 1 else 0 end) as set4, 

FROM *{table}* GROUP BY [OrganizationName]; 

Die obige Abfrage wird Ihnen die gewünschte Ausgabe

Answer 2

select * 
    from 
    (
     select OrganizationName, set, Frequency 
     from Tablename 
    ) src 
    pivot 
    (
     sum(Frequency) 
     for set in ([1], [2], [3],[4]) 
    ) piv;
