如何在MySQL中使用UNION時進行分頁？

我有一個複雜類型的數據庫，不幸的是，由於某種原因，我無法更改。如何在MySQL中使用UNION時進行分頁？

我必須在桌子之間強制UNION，並且必須顯示一張桌子。

我想爲表格做分頁，因爲它會返回一個大數據表。

但它不工作。

當我不使用UNION並從一個表中抓取數據時，這個代碼塊就起作用。

我需要一個解決方案。我在這個問題上遇到了很大的問題。請有人幫助我。

<?php 

conFunc($rootdb); // Connection Strings to Database 

$btsid = trim($_POST['btsid']); 
$date1 = $_POST['date1']; 
$date2 = $_POST['date2']; 

?> 

<b>From:</b> <?php echo $date1; ?> <br /> 
<b>To:</b> <?php echo $date2; ?><br /><br /> 

<?php 
$btsdb = mysql_query("SELECT * FROM `rollout_tracker` WHERE `site_id` LIKE '%".$btsid."'"); 
$rows = mysql_fetch_array($btsdb); 
?>

不！我不這麼認爲...並且，那個頁面不是我的問題的答案... – Nirjhor

您在查詢結尾有一個額外的'）'（或者它會出現）。刪除它並重試。

更重要的是 - 在嘗試使用數據之前，做一下@Bad Wolf所說的並檢查結果（和錯誤信息）。

我已經刪除'）'，並試圖把mysql_error（），但沒有找到解決方案... – Nirjhor

如果你把字符串（與適當的替代）放入mysql cmd行，你會得到什麼輸出？ – ethrbunny

我發現了一個問題點。我使用GROUP BY，因爲這個原因這個頁面顯示1行（這是正常的）。但處理程序頁面（上面給出的代碼）顯示「1-15」，因爲實際上有15行到來，在本頁面顯示爲1行，因爲我已經使用了GROUP BY。但在這種情況下，我應該使用什麼來分頁，我不理解... – Nirjhor
