wish helps you you need to pass default db name in connection string directly. if you need connect to one more database you can use select statment
code :
$db_connect = new mysqli($host, $db_username, $db_password, $db_name);

I hope this helps you . Selecting a database is different than selecting a table. A database can contain multiple tables and a MySQL server can contain more than one database. I'm not sure what system you're using to access your databases but unless configured elsewhere (which it very well may be) it is normally necessary to select a database.

Can one induce a user-defined error from an OpenCL kernel?

I wish this helpful for you Unfortunately, this is something missing from OpenCL. As the question you referenced suggested you do have printf to report an error, but even that is kind of clunky and doesn't help you detect an error programmatically.
If you are really set on returning an error codes, I can think of a couple options (none easy).
code :
#ifndef RETURN_STATUSES
#define RETURN_STATUS(S) \
  do { \
    _kernel_status[get_global_id(0)] = (S); \
    return; \
  } while (0)
#else
#define RETURN_STATUS(S) return
#endif

kernel void myKernel(
  ... normal args
#ifdef RETURN_STATUSES
  , global int *_kernel_status
#endif
  )
{
  ...
  if (i < j) {
    RETURN_STATUS(-9999);
  }
}

With these it helps Note this answer does not explain every breach! It only explains the two most common.
Protect against SQL Injection
code :
<?php
$value = "blue";
$query = "select * from table where column = '" . mysqli_real_escape_string($value) . "'";
<?php
$dbh = new PDO('mysql:host=localhost;dbname=yourdbname;charset=utf8', 'yourUsername', 'yourPassword');
$stmt = $dbh->prepare("SELECT * FROM REGISTRY where name = :name");
$stmt->execute(array('name' => $name));
$allResults = $stmt->fetchAll(PDO::FETCH_COLUMN);
<script>
  alert('xss');  
</script>
echo htmlspecialchars($value);

I wish did fix the issue. Hypothetically, I have a switch that has 437 cases. I've identified every possible case (I think), and each is handled. I'm worried that I missed # 438, and want something in the Default to alert me of this. , Why not to throw an error?
code :
default: 
    throw new Error("Default reached");

hope this fix your issue For your code to be testable without resorting to hackish tricks, you should separate the concerns of "being a SwingWorker" and doing the actual business logic.
Have a SwingWorker that takes a Runnable or similar and have a separate class implement the Runnable so you can instantiate that and test it independently.
