我想添加一个计数器以显示每个查询插入的记录顺序。
if(isset($_POST['keyword'])){
$keyword = $_POST['keyword'];
if($keyword){
foreach($keyword as $row){
$keyword_exe = $con->prepare("
INSERT INTO t_theme(m_id,keyword,sequence_counter)VALUES('$id','$row', '???')
");
$keyword_exe->execute();
}
}
}
我希望输出如下:
答案 0 :(得分:0)
$counter = 0;
$pre_row = 0;
foreach($keyword as $row){
if( $pre_row == $id){
//In row m_id value equal to next value increase counter by 1
$counter++;
}else{
//else start to 1
$counter = 1;
$pre_row = $id;
}
$keyword_exe = $con->prepare("
INSERT INTO t_theme(m_id,keyword,sequence_counter)VALUES('$id','$row', '$counter')
");
$keyword_exe->execute();
}
答案 1 :(得分:0)
我没有使用INSERT进行测试,但是在选择时可以使用它
ROW_NUMBER() OVER(PARTITION BY m_id ORDER BY id ASC) sequence_counter
为了节省一些数据库空间
