将blob从一个表复制到另一个表

Question

我正在尝试将一些列数据从一个表移动到另一个表。 一切都在移动，但图像（blob）从未复制到新位置。我已经更新了我的代码，用一个新的ID将图像从一个表移动到另一个表。

这是我的疑问：

<?php


logit("\nSwap Lane\n");

$camTable = $_POST['cam'];
$plate = $_POST['plate'];
$id = $_POST['id'];
$tmp = explode("-", $id);
$tableEntryId = $tmp[0];

$tmp= explode('_anpr_vega', $camTable);
$camName = $tmp[0];
if ($camName == "archive")
  {
    print "{\"iv\":\n";
    print "  { \"result\": \"FAILED\"} \n";
    print "}\n";
    exit;
  }

print "{\"iv\":\n";

$custId = $_SESSION['customerID'];
$userId = $_SESSION['userId'];
