DataSource Controls :: Uploading Data From Excel Sheet Into DB Dynamically
Jun 28, 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.
I have a web page which I have created to allow users to upload excel file sheet and thus these sets of data will be inserted into the database. However, as I was testing out, I realized that if the excel file is too large (i.e. mulitple sheets, > 5 sheets) , the portal may not be able to handle the large amount of data and displayed error message like the connection is reset. I tried it with only less than 5 sheets it will be fine. Any idea if there are any codes or mechanism which could solve this problem?
i am Using sql server 2005. i want to copy the data of the excel file to the table.
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. Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)".
i want to copy the data of the excel sheet to the table.
i have an aspx page which has a fileuploader and a button
initially i have to browse the file and after browsing the file i have to check the extension if the extension is xsl or xslx then only i have to enable the submit button
once the submit button is enabled i have to insert this data into the table
and i have to display the number of succesfully inserted rows and no of unsuccessfull insertions .
success and failure is dependent on the mismatch of the datatype between the excel sheet and the database column

I was requested to develop a GridView like screen to allow easy DataEntry without the need to Click Save/Submit on each row of the GridView.
In other words, the user wants to edit the GridView Cells in a Web Screen as if he is editing Cells in MS Excel. The Data should be saved as soon as he will exit the cell by pressing the down arrow.
It think the only way to do that is to use Ajax technology, right ?
