Question

I’ve set up PHP (5.2) with PDO (MySQL 5.1) to throw exceptions when an error occurs:

$pdo = new PDO(...);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

Now, I get sometimes an exception that only tells me “HY000: General error”. I’ve tried to get more info out of PDO, but all I can say is that:

• errorInfo(): array(0 => 'HY000')
• errorCode(): array(0 => '00000')

The query that fails looks like this:

INSERT INTO user_values
SELECT user_id,
       attribute_id,
       ?,
       value 
  FROM user_values 
 WHERE user_id = ? 
   AND set_id = ?

I’ve ensured that all cursors are properly closed ($stmt->closeCursor()). The exception is thrown when calling fetchAll() on my statement. After some searching around I found that some are just ignoring this error, but it seems just plain wrong to dismiss a PDO exception.

What to do? Do I have to check like “It’s an INSERT, there is no result set so ignore those exception” (as I don’t have separate methods for INSERT, SELECT, UPDATE, …).

Answer 1

error code 00000 means successful (or rather no error found).
