Question

我是使用谷歌图表的新手，我无法弄清楚为什么我的查询没有显示在我的谷歌图表（表格）中。然而，表显示另一个查询。我试图显示的查询没有显示像我的第一个查询那样的表。

我似乎无法理解问题所在，因为我多次测试了我的查询，甚至在SQL Server中运行它，它确实生成了我要查找的输出，但它根本没有显示在表中

工作查询：

SELECT Researcher.FirstName + ' ' + Researcher.Surname AS [Researcher_Name], Count(Submission.SubmissionID) AS [Number_of_Submissions] FROM Submission INNER JOIN ((Faculty INNER JOIN School ON Faculty.FacultyID = School.[FacultyID]) INNER JOIN (Researcher INNER JOIN ResearcherSubmission ON Researcher.ResearcherID = ResearcherSubmission.ResearcherID) ON School.SchoolID = Researcher.SchoolID) ON Submission.SubmissionID = ResearcherSubmission.SubmissionID GROUP BY Researcher.FirstName, Researcher.Surname;

这是不显示Google图表的查询。注意：当我在SQL生成器中运行此查询时，它会显示我要查找的结果：

SELECT Submission.Title AS [Title], Submission.Status AS [Submission_Status] FROM Submission INNER JOIN ((Faculty INNER JOIN School ON Faculty.FacultyID = School.[FacultyID]) INNER JOIN (Researcher INNER JOIN ResearcherSubmission ON Researcher.ResearcherID = ResearcherSubmission.ResearcherID) ON School.SchoolID = Researcher.SchoolID) ON Submission.SubmissionID = ResearcherSubmission.SubmissionID GROUP BY Submission.Status, Submission.Title;

这是我的完整代码和工作查询，我已经注释掉了不工作的代码：

@{
                        var db = Database.Open("RMSContext");

                        String rows = "";



                        var Query = ("SELECT Researcher.FirstName + ' ' + Researcher.Surname AS [Researcher_Name], Count(Submission.SubmissionID) AS [Number_of_Submissions] FROM Submission INNER JOIN ((Faculty INNER JOIN School ON Faculty.FacultyID = School.[FacultyID]) INNER JOIN (Researcher INNER JOIN ResearcherSubmission ON Researcher.ResearcherID = ResearcherSubmission.ResearcherID) ON School.SchoolID = Researcher.SchoolID) ON Submission.SubmissionID = ResearcherSubmission.SubmissionID GROUP BY Researcher.FirstName, Researcher.Surname;");

                        //var Query = ("SELECT Submission.Title AS [Title], Submission.Status AS [Submission_Status] FROM Submission INNER JOIN ((Faculty INNER JOIN School ON Faculty.FacultyID = School.[FacultyID]) INNER JOIN (Researcher INNER JOIN ResearcherSubmission ON Researcher.ResearcherID = ResearcherSubmission.ResearcherID) ON School.SchoolID = Researcher.SchoolID) ON Submission.SubmissionID = ResearcherSubmission.SubmissionID GROUP BY Submission.Status, Submission.Title;");


                        var AppQuery = db.Query(Query);


                        List<string> rowsList = new List<string>();

                        foreach (var item in AppQuery)
                        {
                            rowsList.Add("['" + item.Researcher_Name + "', " + item.Number_of_Submissions + "]");
                        };
                        rows = String.Join(", ", rowsList);

                    }


                    <script type="text/javascript" src="https://www.google.com/jsapi"></script>
                    <script type="text/javascript">
                        google.load("visualization", "1.1", { packages: ["table"] });
                        google.setOnLoadCallback(drawTable);


                        function drawTable() {

                            var data = google.visualization.arrayToDataTable([
                              ['Researcher Name', 'Number of Submissions'],
                               @Html.Raw(rows)]);

                            var options = {
                                title: ''
                            };

                            var dashboard = new google.visualization.Dashboard(document.querySelector('#dashboard'));

                            var stringFilter = new google.visualization.ControlWrapper({
                                controlType: 'StringFilter',
                                containerId: 'string_filter_div',
                                options: {
                                    filterColumnIndex: 0
                                }
                            });

                            var table = new google.visualization.ChartWrapper({
                                chartType: 'Table',
                                containerId: 'table_div',
                                options: {
                                    showRowNumber: false
                                }
                            });

                            dashboard.bind([stringFilter], [table]);
                            dashboard.draw(data);
                        }
                        google.load('visualization', '1', { packages: ['controls'], callback: drawTable });
                    </script>

                    <div id="dashboard">
                        <div id="string_filter_div"></div>
                        <div id="table_div"></div>
                    </div>

我觉得我错过了一些非常简单的东西，但却无法说谎。

首先，您最不需要GROUP BY，因此删除行GROUP BY Submission.Status, Submission.Title;可能您不需要GROUP BY，而是意味着使用{ {1}}功能和您的ROW_NUMBER()完全奇怪，修改如下
