Oracle to Excel - PL/SQL export procedure

Question

I’m writing pl/sql procedure that exports data from Oracle to Excel. I need data formatting so I can’t use CSV. I’ve already tried with XML but it generates too large files

Answer 1

I've had similar issues and eventually made a spreadsheet with some VBA code that queried and populated the spreadsheet for me. My task was to export a series of tables, each one on a different sheet, but any flag could be used to switch to a new sheet. Anyhow, let me know if you would like to see the code. Here is a chunk that might help you out. Just change the TableSQL string to whatever your select should be. Each record returned will be inserted as a row in the sheet. Then, based on whatever flag you decide, you can create and move to the next sheet. Please let me know if you need more information (as this particular example isn't EXACTLY what you are doing)

Private Sub getMyRows(inSchema As String, InTable As String)
    Dim RS As Object
    Dim TableSQL As String
    Dim DataType As String
    Dim DataLength As String
    Dim DataPrecision As String
    Dim DataScale As String
    Dim ColCount As Integer
    Dim WS As Worksheet
' create a sheet with the current table as name
    Worksheets.Add().Name = InTable
    Set RS = CreateObject("ADODB.recordset")
    TableSQL = "Select * from " & inSchema & "." & InTable
' grab the data
    RS.Open TableSQL, conn, adOpenStatic
    For ColCount = 0 To RS.Fields.Count - 1
' set column headings to match table
       ActiveSheet.Cells(1, ColCount + 1).Value = RS.Fields(ColCount).Name
    Next

' copy table data to sheet
     With Worksheets(InTable).Range("A2")
        .CopyFromRecordset RS
    End With
    RS.Close

  End Sub
