从数据库中删除多条记录

Question

我有一个显示所有产品的 product.On 仪表板 details.There 是一次删除多个产品的复选框。为此，我正在使用此代码：

    $id=array('0'=> 'ab','1'=> 'bc','2'=> 'cd','3'=> 'de',.......);
    $packids=implode("','", $id);
    $packids= ('ab','bc','cd','ef',.....);// n numbers of record
    $sql = "DELETE from app_and_page where `Package` IN ($packids) and `user_created`=$uid";
    $retval = mysql_query( $sql, $link );

此查询只删除一个row.How我可以一次删除所有选定的行吗？

Answer 1

$packids= ('ab','bc','cd','ef',.....);// n numbers of record $sql = "DELETE from app_and_page where Package IN (substr($packids, 0, strlen($packids)-1)) and user_created=$uid"; $retval = mysql_query( $sql, $link );

试试这个。我认为您必须从我们的 packids 字符串中删除最后一个逗号。

Answer 2

我认为包 ID 中的问题只是试试这个代替

$id=array('0'=> 'ab','1'=> 'bc','2'=> 'cd','3'=> 'de',.......);
$packids=implode("','", $id);
$packids= ('ab','bc','cd','ef',.....);// n numbers of record
$sql = "DELETE from app_and_page where `Package` IN ($packids) and `user_created`=$uid";
$retval = mysql_query( $sql, $link );

使用这个

$id=array('0'=> 'ab','1'=> 'bc','2'=> 'cd','3'=> 'de',.......);
$packids=implode("','", $id);
$packids="('".$packids."')";
$sql = "DELETE from app_and_page where `Package` IN $packids and `user_created`=$uid";
$retval = mysql_query( $sql, $link );

它会为你工作。

编辑

这样试试

$sql = "DELETE from app_and_page where trim(`Package`) IN $packids and `user_created`=$uid";
