MYSQL-在循環周結束日期時顯示數據

Question

在過去的一個月裏，我一直在創建一個基準測試系統，允許用戶添加類別&基準測試項目，該測試項目在特定年份內每週保留數據。我無法創建一個mysql語句，該語句在每年的所有星期內顯示每個基準項目的結果，即使那一週沒有數據或一年中沒有數據。以下是我一直在測試的查詢和表格列。我正在使用codeigniter，並計劃以底部顯示的格式顯示結果。我爲這篇冗長的描述道歉，但我試圖儘可能清楚。任何幫助將不勝感激。

tblbenchmarkitem 
================= 
itemID | itemDescription | itemTarget | ItemFreq | FKcategoryID 

tblbenchmarkData 
================ 
dataID | FKitemID | resultDate | result | dateAdded | dateModified 

tblcategories 
=============== 
categoryID | categoryName | parentID | FKdeptID 

tblcalendardates - stores 52 weeks for year Saturday to Friday 
================ 
id | year | startDate | endDate 

這些是我在模型中的mysql語句。我將在該年的函數參數中設置一個默認值。

public function get_data() { 
    $dates = $this->db->query("SELECT endDate FROM tblcalendardates WHERE year = '2014' ORDER BY endDate"); 
    $dates = $dates->result(); 
    foreach ($dates as $date) { 
     //$query = "SELECT tblcalendardates.enddate, tblbenchmarkitems.itemDescription, tblbenchmarkitems.itemTarget, tblbenchmarkitems.itemFrequency, tblbenchmarkdata.resultDate, IFNULL(tblbenchmarkdata.result,0) AS result, (SELECT strCategoryName FROM tblcategories WHERE tblbenchmarkitems.FKcategoryID = tblcategories.categoryID) AS category FROM tblbenchmarkdata LEFT JOIN tblbenchmarkitems ON tblbenchmarkdata.FKitemID = tblbenchmarkitems.itemID JOIN tblcalendardates WHERE DATE(tblbenchmarkdata.resultDate) BETWEEN (SELECT MIN(DATE(tblcalendardates.startdate)) FROM tblcalendardates WHERE tblcalendardates.year = " . date('Y') . ") AND (SELECT MAX(DATE(tblcalendardates.enddate)) FROM tblcalendardates WHERE tblcalendardates.year = " . date('Y') . ") GROUP BY category ORDER BY tblcalendardates.enddate"; 
     $query = 'SELECT c.*, i.itemDescription, i.itemTarget, IFNULL(d.result, 0) as result,"' . $date ->endDate . '" FROM tblcategories AS c JOIN tblbenchmarkitems AS i ON i.FKcategoryID = c.categoryID JOIN tblbenchmarkdata as d ON i.itemID = d.FKitemID JOIN tblcalendardates WHERE DATE(d.resultDate) BETWEEN (SELECT MIN(DATE(tblcalendardates.startdate)) FROM tblcalendardates WHERE tblcalendardates.year = "' . date('Y') . '") AND (SELECT MAX(DATE(tblcalendardates.enddate)) FROM tblcalendardates WHERE tblcalendardates.year = "' . date('Y') . '") GROUP BY strCategoryName'; 
     $query = $this->db->query($query); 

    return $query->result(); 
    } 
} 

這在我看來是

<table class="table table-hover data-list"> 
    <thead> 
     <tr> 
      <th class="th-set-width1">Benchmark Item</th> 
      <th class="th-set-width2">Target</th> 
     <?php foreach($weeks as $week): ?> 
      <th class="th-set-width2"><?php echo date('m-d-Y', strtotime($week->enddate)); ?></th> 
     <?php endforeach; ?> 
     </tr> 
    </thead> 
    <tbody> 
     <?php foreach($entries as $entry) : ?> 
     <tr> 
      <td><?php echo $entry->itemDescription; ?></td> 
      <td><?php echo $entry->itemTarget; ?></td> 
      <?php for ($i = 0; $i < 52; $i++) : ?> 
      <?php if ($entry->result != NULL || $entry->result > 0): ?> 
       <td><?php echo $entry->result; ?></td> 
      <?php else: ?> 
       <td>0</td> 
      <?php endif; ?> 
      <?php endfor; ?> 
     </tr> 
     <?php endforeach; ?> 
    </tbody> 
</table> 

這是我想在一個表格中顯示的數據。

----------------------------------------------------------------------------------- 
categoryName 
==================================================================================== 
itemDescription | itemTarget | 01-03-14 | 01-10-14 | 01-17-14 | 01-24-14 | 01-31-14 
===================================================================================== 
No. of Visits | 12.00 | NULL | NULL | 15.00 | NULL | 20.00 
No. of Calls | 17.00 | 12.00 | NULL | 17.00 | 22.00 | NULL 

Answer 1

我已經添加了一些對我的代碼的更改，幾乎可以得到我期待的響應。現在唯一的問題是，我有兩個項目正在顯示，每個項目的結果。

我的模型：

public function get_data() { 
    $items = $this->db->query('SELECT * FROM tblbenchmarkitems'); 
    $items = $items->result(); 
    foreach ($items as $item) { 
     $query = 'SELECT c.endDate, IFNULL(d.result,0) as result FROM tblbenchmarkdata AS d RIGHT JOIN tblcalendardates as c ON (DATE(d.resultDate) = c.endDate) JOIN tblbenchmarkitems as i WHERE c.year = "2014" AND i.itemID = "' . $item->itemID .'" GROUP BY c.endDate'; 
     $query = $this->db->query($query); 
     $data[] = array(
      'itemID'   => $item->itemID, 
      'itemDescription' => $item->itemDescription, 
      'itemTarget'  => $item->itemTarget, 
      'dates'    => $query->result() 
     ); 
    } 
    return $data; 
} 

我的看法：從查詢結果

<table class="table table-hover data-list"> 
    <thead> 
    <tr> 
     <th class="th-set-width1">Benchmark Item</th> 
     <th class="th-set-width2">Target</th> 
    <?php foreach($weeks as $week): ?> 
     <th class="th-set-width2"><?php echo date('m-d-Y', strtotime($week->enddate)); ?></th> 
    <?php endforeach; ?> 
    </tr> 
    </thead> 

    <tbody> 

    <?php for($n = 0; $n < count($entries); $n++) : ?> 

    <tr> 
     <td><?php echo $entries[$n]['itemDescription']; ?></td> 
     <td><?php echo $entries[$n]['itemTarget']; ?></td> 
     <?php for($i = 0; $i < count($entries[$n]['dates']); $i++) :?> 
     <td><?php echo $entries[$n]['dates'][$i]->result; ?></td> 
     <?php endfor; ?> 
    </tr> 

    <?php endfor; ?> 

    </tbody> 

</table> 

表格式 - 問題是記錄一個記錄兩個具有顯示兩個結果。記錄一個具有記錄在14年11月7日和記錄兩個結果有記錄在14年7月11日結果：

Answer 2

解決

在這個模型中，我改變了我的查詢刪除加入到tblbenchmarkitems表並刪除需要在where語句中指定itemID。我將FKitemID字段添加到輸出中以幫助確保結果對應於正在評估的特定項目（即，如果項目ID爲1並且陣列中提供的結果屬於ID爲1的項目，則顯示數據僅用於ID 1.）

模型中的函數獲取基準數據。

public function get_data() { 
    $items = $this->db->query('SELECT * FROM tblbenchmarkitems'); 
    $items = $items->result(); 
    foreach ($items as $item) { 
     $query = 'SELECT c.endDate as weekending, IFNULL(d.result,0) as result, d.FKitemID FROM tblbenchmarkdata AS d RIGHT JOIN tblcalendardates as c ON (DATE(d.resultDate) = c.endDate) WHERE c.year = "2014" GROUP BY weekending'; 
     $query = $this->db->query($query); 
     $data[] = array(
      'itemID'   => $item->itemID, 
      'itemDescription' => $item->itemDescription, 
      'itemTarget'  => $item->itemTarget, 
      'dates'    => $query->result() 
     ); 
    } 
    return $data; 
} 

的視圖：

<table class="table table-hover data-list"> 
    <thead> 
    <tr> 
     <th class="th-set-width1">Benchmark Item</th> 
     <th class="th-set-width2">Target</th> 

    <?php foreach($weeks as $week): ?> 
     <th class="th-set-width2"><?php echo date('m-d-Y', strtotime($week->enddate)); ?></th> 
    <?php endforeach; ?> 

    </tr> 
    </thead> 

    <tbody> 

    <?php for($n = 0; $n < count($entries); $n++) : ?> 
    <tr> 
     <td><?php echo $entries[$n]['itemDescription']; ?></td> 
     <td><?php echo $entries[$n]['itemTarget']; ?></td> 

    <?php for($i = 0; $i < count($entries[$n]['dates']); $i++) :?> 
     <?php if ($entries[$n]['itemID'] == $entries[$n]['dates'][$i]->FKitemID) : ?> 

     <td><?php echo $entries[$n]['dates'][$i]->result; ?></td> 

     <?php else: ?> 

     <td>0.00</td> 

     <?php endif; ?> 
    <?php endfor; ?> 

    </tr> 
    <?php endfor; ?> 

    </tbody> 
</table> 

最後，在視圖我添加了一個，如果第二for循環（在整個周輸出該數據的一個）之後的語句。它會檢查是否有正在輸出項目的ID的結果，如果它確實顯示，則只在與其對應的行&列中顯示它。如果不是，則顯示「0」。00「。
