Databases :: How To Read Excel Table

Aug 18, 2010

If I use Microsoft.Jet.OLEDB.4.0 to retreive for example named range or sheet from Excel and use it as data source for some server control on the ASP page, everything works fine. But when I try to get table from Excel like this: "select * from [Table1]", debugger complains that database engine could not find object Table1.

Databases :: Read Data From Excel

Aug 31, 2010

i had 2 columns in the excel file one is SNo and another Description

looks like below
Sno Description
1 1/2 Feet
2 1/5 Feet
3 20
4 30

i read the data from this file using below code

string strFileName = FileUpload1.PostedFile.FileName;
string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFileName + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection objConn = new OleDbConnection(connectionString);
objConn.Open();
String strConString = "SELECT * FROM [Product Classification 5$]";
//where date = CDate('" + DateTime.Today.ToShortDateString() + "')";
OleDbCommand objCmdSelect = new OleDbCommand(strConString, objConn);
// Create new OleDbDataAdapter that is used to build a DataSet
// based on the preceding SQL SELECT statement.
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
// Pass the Select command to the adapter.
objAdapter1.SelectCommand = objCmdSelect;
// Create new DataSet to hold information from the worksheet.
DataSet objDataset1 = new DataSet();
objAdapter1.Fill(objDataset1, "ExcelData");

but in it doesnt read the Description data of 20 & 30 because somebody said if the first cell value is string type then all the column should be string but in mycase its coming as mixed(alpha & numeric), so that it cant read the data, i tried to convert the column as Text then also the same problem continues,
