Over the past few weeks, I’ve been learning more about XSL, Javascript, and CSS. Along the way, I’ve been doing much more work with PDO. Yesterday I encountered a 501: Internal Server Error which had me stumped until this morning.

The SQL was something like this:

INSERT INTO mybconfig.keys (key_name, key_type_id) VALUES ( :key_name, :key_id_type )’

Upon calling execute(), the exception thrown was similar to this:

501: Internal Server Error

Description: The server encountered an internal error or misconfiguration and was unable to complete your request.

Message: HY093: SQL: INSERT INTO mybconfig.keys (key_name, key_type_id) VALUES ( :key_name, :key_id_type )

The code looked like this (greatly simplified for demonstration purposes):

$query = $this->tPDO->prepare('INSERT INTO keys (key_name, key_type_id) VALUES ( :key_name, :key_id_type )');
$query->bindValue( ':key_name',  'testing');
$query->bindValue( ':key_type_id', 1);

Look for a while, then find the problem. I know the cause, and will update this post with the solution.

  1. “key_type_id” vs “key_id_type”

  2. Ron: Yes, that’s the issue.

    I encountered this same problem yesterday. I mentioned it to my DBA. He didn’t recognize the error code.

    He went searching for it, and found this article. :)
