Javascript MD数组：如果值为'，则添加其他数组；找不到

我目前正在尝试使用Google tables生成一个基于我从MYSQL数据库中获取的信息的报告

问题是有5个标题值：

[‘呼叫处理’、‘应答’、‘忙’、‘无应答’、‘失败’]

但问题是，从数据库中提取的数据几乎会有4个值中的3个，这将定义我的Google图表标题，原因是如果找到“Failed”并且只有一个值，我从Google图表中得到以下错误：

Uncaught error:第0行有4列，但必须有5列

为了让数据库更清晰，这些值是根据调用发生的情况自动插入的，并非所有调用都会失败

只有少数实例的值会失败，因此我尝试开发一种方法，如果找不到特定数字的值，则添加该额外数组

例如，根据am从DB中取出并放入MD阵列的内容，它当前的外观如下：

[ [ 'ANSWERED', '477', 728 ],
  [ 'BUSY', '477', 48 ],
  [ 'NO ANSWER', '477', 277 ],
  [ 'ANSWERED', '488', 953 ],
  [ 'BUSY', '488', 9 ],
  [ 'FAILED', '488', 1 ],
  [ 'NO ANSWER', '488', 126 ] ]

因此，如果假设没有一个数组的数字没有失败的处置，请添加它，但每次找不到每个数字时都将该值设置为0：

[ [ 'ANSWERED', '477', 728 ],
  [ 'BUSY', '477', 48 ],
  [ 'FAILED', '477', 0 ],
  [ 'NO ANSWER', '477', 277 ],
  [ 'ANSWERED', '488', 953 ],
  [ 'BUSY', '488', 9 ],
  [ 'FAILED', '488', 1 ],
  [ 'NO ANSWER', '488', 126 ] ]

我现在掌握的代码如下：

    function SQLReportAgentCalls() {
    valueArr = [];
    connection2.query({
      sql : 'select disposition, src, COUNT(*) from cdr WHERE src="477" or src="488" GROUP BY src, disposition',
      timeout : 40000
    }, function (error, results, rows, fields) {
        console.log("-----------REPORTS------------------------");
        for(i in results){
                var dipo = results[i]['disposition'];
                var src = results[i]['src'];
                var count = results[i]['COUNT(*)'];

                if(dipo === "FAILED" && count){
                var chanar = new Array(dipo,src,count);
                valueArr.push(chanar);
                }

                else if(src && count === null && dipo !== "FAILED" ){
                var chanar = new Array("FAILED",src,0);
                valueArr.push(chanar);
                }

                else{
                var chanar = new Array(dipo,src,count);
                valueArr.push(chanar);
                }
        }
        console.log(valueArr);
        console.log("---------------------------------------------------");
        SQLReport();
    });
  }

生成报告的客户端代码：

//This generates the report(Google Chart) based on the information that has been pulled from the CDR table server side.
    socket.on("SQL", function (valueArr) {
        google.charts.load('current', {
            packages : ['corechart']
        });
        google.charts.setOnLoadCallback(drawMaterial);
        var data = valueArr;
        function x(data) {
            var r = [],
            temp;
            valueArr.forEach(function (a, i) {
                if (!(i % 3)) {
                    temp = [a[1]];
                    r.push(temp);
                }
                temp.push(a[2]);
            });
            return r;
        }
        function drawMaterial() {

            result = [['Call Disposition', 'Answered', 'Busy', 'No Answer', 'Failed']].concat(x(valueArr));
            console.log(result);
            var options = {
                title : 'Call Disposition',
                hAxis : {
                    title : 'Agents',
                    minValue : 0,
                },
                vAxis : {
                    title : 'Disposition Number'
                },
                isStacked : true
            };
            var chartdata = new google.visualization.arrayToDataTable(result);
            var material = new google.visualization.ColumnChart(document.getElementById('chart'));
            material.draw(chartdata, options);
        }
    });

这可能吗？我不确定Google Charts是否提供了在不存在值时自动添加值的选项，因此这似乎是我能想到的解决问题的唯一方法。

如果阵列需要类似于此

select
  a.src,
  (select count(*) from cdr where src = a.src and disposition = 'ANSWERED'),
  (select count(*) from cdr where src = a.src and disposition = 'BUSY'),
  (select count(*) from cdr where src = a.src and disposition = 'NO ANSWER'),
  (select count(*) from cdr where src = a.src and disposition = 'FAILED')
from
  cdr a
where
  a.src in ("477", "488")
group by
  a.src

[‘呼叫处理’、‘已应答’、‘忙’、‘无应答’、‘失败’]

将SQL更改为以下内容可能会更容易

select
  a.src,
  (select count(*) from cdr where src = a.src and disposition = 'ANSWERED'),
  (select count(*) from cdr where src = a.src and disposition = 'BUSY'),
  (select count(*) from cdr where src = a.src and disposition = 'NO ANSWER'),
  (select count(*) from cdr where src = a.src and disposition = 'FAILED')
from
  cdr a
where
  a.src in ("477", "488")
group by
  a.src

为了获得更好的性能，请将src=“477”或src=“488”更改为：src in（“477”、“488”）@sagi感谢您的提示，我会这样做。为了获得更好的性能，请将src=“477”或src=“488”更改为：src in（“477”、“488”）@sagi谢谢你的提示，我会这么做的。这个数组已经类似于SQL查询不是问题了，当我将它粘贴到一个数组中时，失败不会出现在所有的src编号中，为了清晰起见，我添加了客户端代码。这些值是硬编码的，因为它们不会更改。我建议更改SQL以消除在客户端上操作数据的需要——我提供的SQL如果不存在，将在“FAILED”列中包含一个零……有没有更有效的方法？与我以前相比，由于记录的数量太多，对我来说似乎速度太慢了使用beforethearray已经类似于SQL查询不是问题所在，当我将其粘贴到数组中时，failed不会出现在所有src编号中，为了清晰起见，我添加了客户端代码。这些值是硬编码的，因为它们不会更改。我建议更改SQL以消除在客户端上操作数据的需要——我提供的SQL如果不存在，将在“FAILED”列中包含一个零……有没有更有效的方法？与我以前相比，由于记录的数量太多，对我来说似乎速度太慢了使用前
