    <p>I'm using MVC3 with C# code. I have a table in my SQL Server Express containing some columns, and I have an Excel sheet which has the same number of columns with the same datatypes and names. </p> <p>My requirement is I want to browse that Excel file in my MVC3 application, where the user can select the file. There is a <code>RegistrationNo</code> column in both my database table as well as in the Excel sheet. Before importing the data in the table of the database the <code>RegNo</code> present in the Excel sheet should be compared with the <code>RegNo</code> in the database table and if that <code>RegNo</code> already exists than no insertion for that <code>RegNO</code> should take place else if that <code>RegNo</code> is not present in the table than the row for that <code>RegNo</code> should be inserted.</p> <p>Below is my code that I have tried but I'm getting lot of issues with that.</p> <pre><code>[HttpPost] public ActionResult AdmissionUpload() { string filePath = null; foreach (string inputTagName in Request.Files) { HttpPostedFileBase Infile = Request.Files[inputTagName]; if (Infile.ContentLength &gt; 0 &amp;&amp; (Path.GetExtension(Infile.FileName) == ".xls" || Path.GetExtension(Infile.FileName) == ".xlsx" || Path.GetExtension(Infile.FileName) == ".xlsm")) { filePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, Path.GetFileName(Infile.FileName)); if (System.IO.File.Exists(filePath)) { System.IO.File.Delete(filePath); } Infile.SaveAs(filePath); //Infile.SaveAs(filePath); } if (filePath != null) { System.Data.OleDb.OleDbConnection oconn = new System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filePath.ToString() + ";Extended Properties=\"Excel 12.0 Xml;HDR=YES\";"); oconn.Open(); try { if (oconn.State == System.Data.ConnectionState.Closed) oconn.Open(); } catch (Exception ex) { // MessageBox.Show(ex.Message); } dynamic myTableName = oconn.GetSchema("Tables").Rows[0]["TABLE_NAME"]; OleDbCommand ocmd = new OleDbCommand("select * from [" + myTableName + "]", oconn); OleDbDataReader odr = ocmd.ExecuteReader(); if (odr.HasRows) { while (odr.Read()) { if (odr[0].ToString().Trim() != "") { if (CheckDepartment(odr[0].ToString().Trim()) == false) { var model = new DepartmentMaster(); model.DepartmentName = odr[1].ToString().Trim(); db.DepartmentMasters.AddObject(model); db.SaveChanges(); FLAG = true; } } } } } } return View(); } </code></pre> <p>Here <code>CheckRegNo</code> checks whether the <code>RegNo</code> exists.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
