ASP中的SQL语法错误

标签： javascript html asp.net sql-server-2008

我正在为PowerPoint演示文稿制作一些无限循环的幻灯片。我有两张我负责的幻灯片。一个显示GPA特定括号内的学生人数Screenshot of The Graph，其工作正常

第二个图表显示每个类别（7-12）的平均GPA看起来像Average GPA Graph

代码是用HTML编写的，但是使用ASP查询SQL服务器以将数据拉到bused以使用[Canvas JS]形成图形[3]

这是我的第一个代码

按预期工作，显示第一个屏幕截图中的信息

第二个完全相同，除了一个不同的select语句（我已经测试并知道一个事实有效）和标题。

这段代码甚至不会绘制图形，我无法弄清楚生活中发生了什么。

它返回的源代码是

＆＃13;
＆＃13; 
<!DOCTYPE HTML>


<html>
<head>
<script>
window.onload = function () {

var chart = new CanvasJS.Chart("chartContainer", {
	animationEnabled: true,
	title:{
		text: "Average GPA by Class"
	},
	data: [{
		type: "column",
		indexLabelFontColor: "#5A5757",
		indexLabelPlacement: "outside",
		dataPoints: [
 <font face="Arial" size=2>
<p>Microsoft OLE DB Provider for ODBC Drivers</font> <font face="Arial" size=2>error '80040e14'</font>
<p>
<font face="Arial" size=2>[Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'CadetGPAs'.</font>
<p>
<font face="Arial" size=2>/Grice/AVGPA.asp</font><font face="Arial" size=2>, line 32</font>
＆＃13;
＆＃13;
＆＃13;

但Datapoints部分应该更像

＆＃13;
＆＃13; 
data: [{
		type: "column",
		indexLabelFontColor: "#5A5757",
		indexLabelPlacement: "outside",
		dataPoints: [
			{ label : "7", y: 3, indexLabel: "3" },
			{ label : "8", y: 2.7, indexLabel: "2.7" },
			{ label : "9", y: 4, indexLabel: "4" },
			{ label : "10", y: 2, indexLabel: "2" },
			{ label : "11", y: 1.5, indexLabel: "1.5" },
			{ label : "12", y: 4.3, indexLabel: "4.3" }
＆＃13;
＆＃13;
＆＃13; ASP中的某个地方没有输出数据点
