如何在此处添加 SQL 列值

Question

如何更改提交“updated_by”的“人名”mysql 列？

<?php
$updated_by=$_GET['updated_by'];
$sql = "SELECT * from neonat_patient where updated_by='Name of the Person';";
$query = $dbh -> prepare($sql);
$query-> bindParam(':updated_by', $updated_by, PDO::PARAM_STR);   
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=1;
if($query->rowCount() > 0)
{
foreach($results as $result)
{               
?>

只是将“人名”替换为几处更改？ 以及绑定参数的一些变化

<?php
$updated_by=$_GET['updated_by'];
$sql = "SELECT * from neonat_patient where updated_by=?";
$query = $dbh -> prepare($sql);
$query-> bindParam(1, $updated_by, PDO::PARAM_STR);   
$query->execute();
$results=$query->fetchAll(PDO::FETCH_ASSOC);
$cnt=1;
if($query->rowCount() > 0)
{
foreach($results as $result)
{               
?>
