Question

我通过php脚本一次将50条记录插入到数据库中。但它在插入时会跳过2-3条记录。有什么问题？

请帮忙！

我想LIMIT中存在一些问题。请检查任何人，并告诉我们！

以下是代码：

<?php
include_once 'db.php';
$selTable = "select * from dump_hotelbasicinfo LIMIT 50";
$resultTable = mysql_query($selTable, $conn);
while($rowTable = mysql_fetch_array($resultTable))
{
    echo "<br> <strong> Hotel ID </strong>  : " .$rowTable['id'];
    echo "<br> <strong> Hotel Name  </strong>: " .$rowTable['HotelName'];
    echo "<br> <strong> Hotel Code  </strong>: " .$rowTable['HotelCode'];
    echo "<br> <strong> Chain Code  </strong>: " .$rowTable['ChainCode'];
    echo "<br> <strong> Hotel Type  </strong>: " .$rowTable['HotelType'];
    echo "<br> <strong> Hotel Category  </strong>: " .$rowTable['HotelCategory'];
    echo "<br> <strong> Hotel Style  </strong>: " .$rowTable['HotelStyle'];
    echo "<br> <strong> Hotel Theme  </strong>: " .$rowTable['HotelTheme'];
    echo "<br> <strong> Rating  </strong>: " .$rowTable['StarRating'];
    echo "<br> <strong> Destination Name  </strong>: " .$rowTable['DestinationName'];
    echo "<br> <strong> Country Name  </strong>: " .$rowTable['CountryName'];   
    echo "<br> <strong> Hotel Info  </strong>: " .$rowTable['HotelInfo'];
    echo "<br> <strong> Number of Floors  </strong>: " .$rowTable['NumFloors'];
    echo "<br> <strong> Number of Rooms  </strong>: " .$rowTable['NoOfRooms'];
    echo "<br> <strong> DateTime  </strong>: " .$rowTable['datetimespan'];

    echo "<hr>";

$sqlInsert="INSERT INTO `hotel_info` 
                            (`property_name` , 
                             `property_town` ,
                             `property_country` , 
                             `property_description`, 
                             `published` , 
                             `stars` , 
                             `ptype_id` , 
                             `last_changed`
                             ) 
               VALUES
                       ('$rowTable[HotelName]' , '$rowTable[DestinationName]' , '$rowTable[CountryName]', ' $rowTable[HotelInfo]','1' ,
                       '$rowTable[StarRating]' , '1','$rowTable[datetimespan]')";
                       //echo $sqlInsert;
                       //exit();

    $resultInsert = mysql_query($sqlInsert);




}
?>

Answer 1

可能你在插入查询中有错误打印sql代码并检查查询是否正确。

//...
echo $sqlInsert;
 //exit();

Answer 2

由于您没有转义任何输入字符串，因此极有可能在某些表（可能是属性名称）中包含撇号（＆＃39;）或任何其他受限制的字符，从而阻止您插入该特定查询。例如，如果城市坎贝尔湾，它将不会在没有首先逃避撇号的情况下插入。

使用mysql_real_escape_string

不要使用mysql _ 函数，因为它们已被弃用，请改用mysqli_ * *
