我目前正在尝试使用 Google 表格根据从我的 MYSQL 数据库中提取的信息生成报告。
问题是有 5 个 header 值:['Call Disposition', 'Answered', 'Busy', 'No Answer','Failed']
但问题是从数据库中提取的数据几乎有 4 个值中的 3 个值将定义我的 Google 图表标题，原因是如果找到“失败”并且只有一个值有我从 Google Charts 收到以下错误:Uncaught Error: Row 0 has 4 columns, but must have 5
为了让数据库更加清晰，值会根据调用发生的情况自动插入，并非所有调用都会失败。
只有少数实例的值会失败，因此我正在尝试开发一种方法，如果找不到特定数字的值，则添加该额外数组。
例如，这是当前基于从数据库中拉出并插入 MD 阵列的内容的外观:
[ [ '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，如果说没有包含没有 Failed 处置的数字的数组，请添加它，但每次都找不到每个数字时，将值设置为 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 是否提供了在值不存在时自动添加值的选项，所以这似乎是我能想到的解决问题的唯一方法。
最佳答案
如果数组需要类似于这样...
['调用处理', '已应答', '占线', '无人应答','失败']
将 SQL 更改为这样的内容可能会更容易......
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
