PHP Bug Type: PDO related
Bug description: PDO->query ('SELECT ...', PDO::FETCH_COLUMN, -1) - error or
not?
Description:
------------
What is PDO->query('SELECT ...', PDO::FETCH_COLUMN, $colno) supposed to do
if you pass an invalid column number in $colno, e.g.:
$stmt = $pdo->query('SELECT only_column FROM test', PDO::FETCH_COLUMN,
-1);
My preference would be to make PDO bail about the invalid offset. However,
I do not know if this would work with all drivers. So, maybe its even
technically not possible to make PDO emit a warning if the requested column
is not available.
In any case, I ask to update the manual and tell people about this edge
case.
Reproduce code:
---------------
[EMAIL PROTECTED]:~/php53> sapi/cli/php -r '$pdo=new
PDO("sqlite:/tmp/foo.db"); @$pdo->exec("DROP TABLE test");
$pdo->exec("CREATE TABLE test(id INT)"); $pdo->exec("INSERT INTO test(id)
VALUES (1)"); var_dump($pdo->query("SELECT id FROM test",
PDO::FETCH_COLUMN, -1)->fetchAll());'
array(0) {
}
(Same with MySQL)
Expected result:
----------------
If possible, make PDO bail out when calling query() with invalid column
offsets. If that's not possible for technical reasons, please consider
having a note about this in the manual.
