我对将Excel单元格数据导入sqlserver数据库有疑问。但是我的Excel数据如下所示:

ID|NAME    |DAY1   |DAY2   |DAY3   |DAY4   |  
--+--------+-------+-------+-------+-------+  
1 |John Doe|shift-1|shift-1|shift-1|shift-1|
--------------------------------------------
2 |Alex    |shift-2|shift-2|shift-2|shift-2|
--------------------------------------------
3 |McArthur|shift-3|shift-3|shift-3|shift-3|
--------------------------------------------

我的数据库格式在下面看起来很幸运:

DateTime|ID|NAME    |SCHEDULE|
--------+--+--------+--------+
DAY1    |1 |John Doe|Shift-1 |
------------------------------
DAY1    |2 |Alex    |Shift-2 |
------------------------------
DAY1    |3 |McArthur|Shift-3 |
------------------------------
DAY2    |1 |John Doe|Shift-1 |
------------------------------
DAY2    |2 |Alex    |Shift-2 |
------------------------------
DAY2    |3 |McArthur|Shift-3 |
------------------------------
DAY3    |1 |John Doe|Shift-1 |
------------------------------
DAY3    |2 |Alex    |Shift-2 |
------------------------------
DAY3    |3 |McArthur|Shift-3 |
------------------------------
DAY4    |1 |John Doe|Shift-1 |
------------------------------
DAY4    |2 |Alex    |Shift-2 |
------------------------------
DAY4    |3 |McArthur|Shift-3 |

然后我尝试写了一个代码,然后偏离了代码。

$fp = fopen($_FILES['csv']['tmp_name'],'r') or die("Can't Open");
while($csv_line = fgetcsv($fp,1024))
{
$cnt = count($csv_line);
for($i=1;$i<=$cnt;$i++){
    $data[$i]['ID']   = $csv_line[1];
    $data[$i]['NAME'] = $csv_line[2];
    $data[$i]['DAY1'] = $csv_line[3];
    $data[$i]['DAY2'] = $csv_line[4];
    $data[$i]['DAY3'] = $csv_line[5];
    $data[$i]['DAY4'] = $csv_line[6];
}
    return $data;
}
    fclose($fp) or die("Error");

有可能做到吗?因为我的公司不想更改旧的excel格式,因为它将影响所有分支机构。

由于您需要按日值对数据进行分组,因此您也需要以这种方式组织循环,即从文件中读取的每一行每天创建一个条目。像这样:

$data = array();
while($csv_line = fgetcsv($fp,1024)) {
    $data[] = array('DATETIME' => 'DAY1', 'ID' => $csv_line[0], 'NAME' => $csv_line[1], 'SCHEDULE' => $csv_line[2]);
    $data[] = array('DATETIME' => 'DAY2', 'ID' => $csv_line[0], 'NAME' => $csv_line[1], 'SCHEDULE' => $csv_line[3]);
    $data[] = array('DATETIME' => 'DAY3', 'ID' => $csv_line[0], 'NAME' => $csv_line[1], 'SCHEDULE' => $csv_line[4]);
    $data[] = array('DATETIME' => 'DAY4', 'ID' => $csv_line[0], 'NAME' => $csv_line[1], 'SCHEDULE' => $csv_line[5]);
}

然后,您应该能够将$data数组的每一行插入到数据库中,例如

foreach ($data as $d) {
    // insert $d into database
}

您可以使用 Unpivot 获得所需的结果。但这在数据库端起作用。首先,您需要将该记录放入数据库中,然后使用Unpivot将记录转换为所需格式。

    GO
    SELECT [datetime], id, name, schedule  
    FROM   
       (SELECT id, name, Day1, day2, day3, day4 
       FROM pvt) p  
    UNPIVOT  
       (schedule FOR [datetime] IN   
          (Day1, day2, day3, day4)  
    )AS unpvt;  
    GO 

您可以使用此输出将其插入表中。
