DataSource Controls :: Column Count Of An Excel Sheet?
Feb 22, 2010

I want to upload data from an Excel Sheet into my DB. Now my major requirement is, I do not know the header count in the files to be uploaded and they may vary, for example one file may have 3 headers while some may have 6. and I want data of both these files to go into a single DB. That is, I want to dynamically generate columns in my DB, and store these values. So how do I go about achieving this.
Can I use MS SQL Server 2005 stored procedure to read data from MS Excel sheet and write into the table.I don't want to do it using C# or any other programming langauage. Simply using stored procedure should read sheet and write into SQL tables.Is its possible to do? If yes, then give me suggestions/sample tutorials for the same.

i wrote the query like :
INSERT INTO test(empId,empName,empMailId,empContactNo) SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C: estExcel.xls', 'SELECT * FROM [Sheet1$]')
got the following error :
SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure. For more information about enabling 'Ad Hoc Distributed Queries', see "Surface Area Configuration" in SQL Server Books Online.
then did this
sp_configure 'show advanced options', 1; GO RECONFIGURE; GO sp_configure 'Ad Hoc Distributed Queries', 1; GO RECONFIGURE; GO
again am trying the same above query ,now am getting the following error:
Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)" reported an error. The provider did not give any information about the error.

I want to import a spreadsheet into SQL. The import/export wizard forces Column A to be a double. In Excel, the column is formatted as text. When I try to convert from double to text/varchar/nvarchar, the import process fails. Why can't I convert a number to text in SQL?
I need a way to read all the rows in one column from an Excel file that the user picks from a fileupload control. I tried saving the excel file on the webserver with the upload control and then opening it with a OleDbConnection but that fails when running it from the webserver and gives the error:
Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=18.104.22.168, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
This works fine when just running it localhost, so i figured it might be a problem with security level at the webserver which i cant change. Instead i tried doing it with a streamreader direct from the fileupload control and because theres no need for saving the excel file on the server, but im not sure how to query the rows i need this way.

I am not an expert in this. let me know if you would need any more information or clarification.
I am trying to create double and number format cells in excel using NPOI library. I used code like
Dim cell As HSSFCell = row.CreateCell(j) cell.SetCellValue(Double.Parse(dr(col).ToString))
In excel numbers are aligning right but when I check format it is showing in "General"
then I changed my code to like below
Dim cell As HSSFCell = row.CreateCell(j) cell.SetCellValue(Double.Parse(dr(col).ToString)) Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle cellStyle.DataFormat = HSSFDataFormat.GetBuiltinFormat("#,#0.0") cell.CellStyle = cellStyle
Then While opening file it is giving error and also taking so long to open. But Excel format showing in "Number" error showing is like below.
