Hello, I wrote app that read excel file, I used oledb and simple query like following

("select * from [Sheet1$]", MyConnection)

It's smoothly working but It defines first row of data from excel file as column name, so I have to insert datatable's column name at index 0 after retrieving data. but There is certain limit in naming DataTable column so it neglect some words exceeding that limit. How can I solve this problem.

I'm not clear what the problem is. Can you post some code or an example of what you're getting / what you want / what's going wrong?

I mean Whenever I retrieve data from excel file, first row data is neglected.
I used following code..
System.Data.OleDb.OleDbConnection MyConnection ;
System.Data.DataSet DtSet ;
System.Data.OleDb.OleDbDataAdapter MyCommand ;
MyConnection = new System.Data.OleDb.OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0;Data Source='mydata.xls';Extended Properties=Excel 8.0;");
MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection);
MyCommand.TableMappings.Add("Table", "excelData");
DtSet = new System.Data.DataSet();
MyCommand.Fill(DtSet);
MyConnection.Close();
-------------------------------------------------------
and if data to be read is as following table

1 | Book | 300 |
2 | Paper | 120 |
3 | Pen | 60 |
---------------------------

then data in dataset is lack of first row (1 | book | 300)
as these values are suggested as column name of table in dataset.

Solution 1

You have probably messed up the HDR value in the connection string. It specifies that the first row is the table header or not.
