Export 344 Columns data to Excel via SSIS


  • Guys,
           For our project we try to export 344 columns data to Excel destination XLSX (2007 to 2010) through data flow task but we end up with error "too many columns defined".

    Is there any workaround to fix this issues  through script task C# code or any other way.  Please help me out on this issue. 

    CREATE TABLE `OLE DB Destination` (
        `Column 0` NVARCHAR(50),
        `Column 1` NVARCHAR(50),    
        `Column 2` NVARCHAR(50),
    `Column 344` NVARCHAR(50)
    ) too many columns defined error

  • Hi Mathan R,

    There are a lot of Limitations when exporting to an Excel Files using Sql server data tools.

    You can do some workaround to achieve this:

    1.Create a data flow task that export your data into a Flat File (csv)
    2.Store your Destination File Name in a Variable
    3.Create another Data flow task that convert your csv file to an Excel File using a script task with a similar Function.

       Imports Microsoft.Office.Interop
        Public Sub ConvertCSVToExcel(Fromcsv As String, Toxlsx As String)
            Dim Exl As New Excel.Application()
                Dim wb1 As Excel.Workbook = Exl.Workbooks.Open(Fromcsv, Format:=4)
                wb1.SaveAs(Toxlsx, FileFormat:=XlFileFormat.xlOpenXMLWorkbook)
            Catch ex As Exception
                            Exl.DisplayAlerts = False
            End Try
        End Sub

    4. The third party components.
