Select 计算字符串然后将它们分组为饼图

Question

我真的需要完成这个，我需要将它们按四个分组，我目前正在为我的 table 使用饼图来显示每个项目的百分比，以及它们使用此查询的计数：

This is my full code: https://www.pastiebin.com/5be43c1f6ec73

$query = "SELECT DISTINCT trendx, COUNT(*) as counter FROM jeremy_table_trend GROUP BY trendx";

那么这是我查询的结果

Escalate                        99
Not Supported                12809
PE.Win32.TRX.XXPE50FFF026       23
PE.Win32.TRX.XXPE50FFF027      102
PUA.Win32.TRX.XXPE50FFF026       1
PUA.Win32.TRX.XXPE50FFF027      16
PUA.Win32.TRX.XXPE50FFF027P0005  1
Ransom.Win32.TRX.XXPE50FFF026   96
Ransom.Win32.TRX.XXPE50FFF027  619
Rapid Proliferation            596
TROJ.Win32.TRX.XX.PE50FFF026     5
Undet                         1425
Undet - component               17
Undet - Feedback               712
Undet - FileSize                 9
Undet - M/P                     73
Undet - Maturity               146

这是我的饼图的输出，但我希望它们按 4 - Undetected, Supported,Escalate and Not Supported 分组。我怎样才能做到这一点？请帮助我

这是我的图表代码：

<!-- Chart code -->
<script>
var chart = AmCharts.makeChart("chartdiv", {
  "fontSize":15,
  "type": "pie",
  "startDuration": 0,
   "theme": "black",

  "angle": 20,
  "export": {

  }
});

chart.addListener("init", handleInit);

chart.addListener("rollOverSlice", function(e) {
  handleRollOver(e);
});

function handleInit(){
  chart.legend.addListener("rollOverItem", handleRollOver);
}

function handleRollOver(e){
  var wedge = e.dataItem.wedge.node;
  wedge.parentNode.appendChild(wedge);
}
</script>

我在想这个主意，但我不知道如何将它们按四个分组

取消删除：

select trendx, COUNT(*) as counter from jeremy_table_trend WHERE trendx LIKE '%Undet%';

升级：

select trendx, COUNT(*) as counter from jeremy_table_trend WHERE trendx LIKE '%Escalate%';

不支持：

select trendx, COUNT(*) as counter from jeremy_table_trend WHERE trendx LIKE '%Not Supported%';

支持：

select trendx, COUNT(*) as counter from jeremy_table_trend WHERE trendx NOT LIKE '%Not Supported%' OR '%Undet%' OR '%Escalate%';

有几种方法可以解决这个问题，您可以使用联合查询

select 'Undet' as trendx, COUNT(*) as counter from jeremy_table_trend WHERE trendx LIKE '%Undet%'
union all
select 'Escalate', COUNT(*) as counter from jeremy_table_trend WHERE trendx LIKE '%Escalate%'
union all
select 'Not Supported', COUNT(*) as counter from jeremy_table_trend WHERE trendx LIKE '%Not Supported%'
union all
select 'Supported', COUNT(*) as counter from jeremy_table_trend WHERE trendx NOT LIKE '%Not Supported%' OR '%Undet%' OR '%Escalate%';

或者您可以使用 case 语句和子查询，例如

select status, count(*) from ( 
  select 
   case 
    when trendx like '%Undet%' then 'Undet'
    when trendx like '%Escalate%' then 'Escalate'
    when trendx LIKE '%Not Supported%' then 'Not Supported'
    else 'Supported'
   end as status
) x group by status

Select 计算字符串然后将它们分组为饼图

Select count strings then group them to pie chart
