如何計算與各種列的值

Question

我有一個具有3列的表：僱員，工作場所，WorkStatus

EmployeeID | WorkPlace | WorkStatus 
    1  | KL  | Baru 
    2  | KK  | Batal 
    3  | PP  | Ubah 
    4  | KL  | Batal 

我想在表中一個PHP頁面，從該表並顯示數據的報告形成這樣的：

No. | WorkPlace |  WorkStatus   | Total | 
    |   | Baru | Batal | Ubah |  | 
------------------------------------------------------- 
    1 | KL  | 1 |  1 | 0 | 2 | 
    2 | KK  | 0 |  1 | 0 | 1 | 
    3 | PP  | 0 |  0 | 1 | 1 | 
------------------------------------------------------- 
    Total  | 1 |  2 | 1 | 4 | 

這是我的SQL查詢：

mysql_select_db($database_conn, $conn); 
$query = "SELECT * FROM permohonan GROUP BY WorkPlace"; 
$Recordset1 = mysql_query($query, $conn) or die(mysql_error()); 

，而這是我的代碼顯示該表：

<table border="1" cellpadding="5" style="border-collapse:collapse"> 
<tr> 
    <th rowspan="2">No.</th> 
    <th rowspan="2">WorkPlacen</th> 
    <th colspan="3">WorkStatus</th> 
    <th rowspan="2">Total</th> 
</tr> 
<tr> 
    <th>baru</th> 
    <th>batal</th> 
    <th>ubah</th> 

</tr> 

<?php 
$bil==0; $sBaru=0; $sBatal=0; $sUbah=0; 
while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)) { 
$bil++; $cBaru=0; $cBatal=0; $cUbah=0; 
     if ($row_Recordset1['WorkStatus'] == 'Baru'){ 
      $cBaru++; 
      $sBaru++; } 
     else if ($row_Recordset1['WorkStatus'] == 'Batal'){ 
      $cBatal++; $sBatal++;} 
     else if($row_Recordset1['WorkStatus'] == 'Ubah'){ 
      $cUbah++; $sUbah++;}?> 
<tr> 
    <td><?php echo $bil."." ?></td> 
    <td><?php echo $row_Recordset1['bhg_cwgn']; ?></td> 
    <td><?php echo $cBaru ?></td> 
    <td><?php echo $cBatal ?></td> 
    <td><?php echo $cUbah ?></td> 
    <td><?php echo $cBaru+$cBatal+$cUbah ?></td> 
</tr> 
<?php } ?> 
<tr> 
    <td colspan=2>Jumlah</td> 
    <td><?php echo $sBaru ?></td> 
    <td><?php echo $sBatal ?></td> 
    <td><?php echo $sUbah ?></td> 
    <td><?php echo $sBaru+$sBatal+$sUbah ?></td> 

</tr> 
</table> 

當我使用該代碼，顯示了當行的WorkPlace = KL爲WorkStatus是1,0,0而不是1,1,0

我該如何解決這個問題？

在查詢我想你想這樣的事情

SELECT WorkPlace, COUNT(WorkPlace) FROM permohonan GROUP BY WorkPlace
