在'mysql_query（）'後面運行'echo mysql_error（）'。請記住，'mysql_ *'函數已被棄用。 –

你的SQL查詢是錯誤的。

SELECT * FROM ocwconnections WHERE FormDistributionDate BETWEEN `fromdate` AND `todate`

被``包圍的字符串被視爲列名。看起來你需要一個變量。

$fromdate = $_GET['fromdate']; 
$todate= $_GET['todate']; 
$sql = "SELECT * FROM ocwconnections WHERE `FormDistributionDate` BETWEEN $fromdate AND $todate ";

這應該工作（未測試）。

請記住，這會打開你的腳本到SQL注入。切換到mysqli_*函數或PDO並使用預準備語句。

感謝它的工作... – MaheshDigarse

但它不顯示來自數據庫表的數據是空的任何解決方案。 – MaheshDigarse

你忘了評論此var_dump($query); exit;。之後，它應該工作。

如果這是腳本甚至不運行'mysql_fetch_array（）'命令的原因。 –

我想你的mysql_query中有一個錯誤。請參閱mysql_query文檔。

對於SELECT，SHOW，DESCRIBE，EXPLAIN和其他返回resultset的語句，mysql_query（）返回成功的資源，錯誤時返回FALSE。

所以，我想你的$查詢變量有一個FALSE。

在獲取行之前總是檢查輸出。在查詢中有一些錯誤。

嘗試這樣做：

if(!$query) 
{ 
echo mysqli_error(); 
}else{ 
    while($row = mysqli_fetch_array($query)) 
    { 
    //fetch rows 
    }

這樣做，你會了解確切的錯誤（避免使用mysql，而是使用mysqli）
