New Post: How to make DateTime format applied without double clicking that particulat column

Hi All,

I've managed to generate and download an excel file from oracle database using PHPexcel, below is my coding for reference:-

// Instantiate a new PHPExcel object
$objPHPExcel = new PHPExcel();
// Set the active Excel worksheet to sheet 0
$objPHPExcel->setActiveSheetIndex(0);
// Initialise the Excel row number
$rowCount = 2;

$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'ATB')->getStyle('A1')->getFill()->applyFromArray(
        array(
      'type'       => PHPExcel_Style_Fill::FILL_SOLID,
      'startcolor' => array('rgb' => 'FFFF00'),
      'endcolor'   => array('rgb' => 'FFFF00'),

   )
);
$objPHPExcel->getActiveSheet()->SetCellValue('B1', 'ATA')->getStyle('B1')->getFill()->applyFromArray(
        array(
      'type'       => PHPExcel_Style_Fill::FILL_SOLID,
      'startcolor' => array('rgb' => 'FFFF00'),
      'endcolor'   => array('rgb' => 'FFFF00')
   )
);


// Iterate through each result from the SQL query in turn
// We fetch each database result row into $row in turn
while($objResult = oci_fetch_array($objParse,OCI_ASSOC+OCI_RETURN_NULLS)){
    // Set cell An to the "name" column from the database (assuming you have a column called name)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, $objResult["ATB"])->getStyle('A'.$rowCount)->getNumberFormat()->setFormatCode('dd/mm/yyyy hh:mm:ss');
    // Set cell Bn to the "age" column from the database (assuming you have a column called age)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, $objResult["ATA"])->getStyle('B'.$rowCount)->getNumberFormat()->setFormatCode('dd/mm/yyyy hh:mm:ss');
    // Increment the Excel row counter
    $rowCount++;
}

// Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
// Write the Excel file to filename some_excel_file.xlsx in the current directory
$objWriter->save('report_actual.xlsx');

So when I open the excel file, the column value of ATB and ATA is formatted as dd/mm/yyyy hh:mm:ss. My intention right now is to SUM all column for ATB and get the total sum as a number. But the problem right now is after SUM all ATB the result is 0, so I need to double click each column for ATB and it will start to calculate the total SUM. Just for your information, my excel file look something like this:

| ATB | ATA |
|22/03/2013 07:00:00 | 21/03/2013 20:20:00 |
|23/03/2013 17:10:00 | 22/03/2013 04:45:00 |

I've noticed when I double click on that particular column, at the formula bar the value (example for ATB 22/03/2013 07:00:00) became like this one 22/3/2013 7:00:00 AM. When the value became like that, the total SUM column will automatically start summing. Imagine if I need to double click one thousand rows!

So I would like to seek any advise/assistance/opinion from experts. Is there any easy way to SUM all ATB without doing this messy work? I would prefer if the SUM also can be calculated automatically using PHPexcel.

(p/s: i knew that excel SUM function is based on 1/1/1900 00:00:00)

Glad if someone could help me. Many thanks.
