您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在“doc_rate”附近使用正确的语法，其中fra_code ='ET7867FRA'和destination ='WITH IN CITY'，mode ='S'在第1行##

<?
if(isset($_POST['Submit']))
{
    $fra_code = $_POST['fra_code'];
    $mode = $_POST['mode'];
    $destination = $_POST['destination'];
    $receiver = $_POST['receiver'];
    // Connect to the database
    $con = mysql_connect($dbhost, $dbusername, $dbuserpassword);
    // Make sure we connected succesfully
    if(! $con)
    {
        die('Connection Failed'.mysql_error());
    }
    mysql_select_db($default_dbname);
    if ($receiver !="")
    {
        // The below query is okay when doing with single deletion but when passing variable from it , the error shows
        $sql = "DELETE from '".$receiver."' where fra_code='".$fra_code."' and destination='".$destination."' and mode='".$mode."'";
        }
        else{
            echo "<script>alert (\"Reciver Mode Not Selected\");history.go(-1)</script>";
        }
        try{
                $result = mysql_query($sql);
                if($result){
                echo "<script>alert (\"Wrong Rate List Deleted\");history.go(-1)</script>";
                exit;
                }
                else{
                    $msg = mysql_error(); // display error so you can fix it
                    echo "<script>alert (\"$msg\"); history.go(-1)</script>";
                }
           }
        catch (Exception $e)
        {
                error_reporting (E_ALL ^ E_NOTICE); 
                echo $e->errorMessage();
        }
    }
}
?>

从表名中删除单引号

 $sql = "DELETE from $receiver where `fra_code`= '$fra_code' and `destination`= '$destination' and `mode` = '$mode' ";

从下拉列表传递php变量以删除mysql记录时出现语法错误
