I looked into 5.3 SVN source code and was able to spot the problem. The
following line is causing the Warning:
php_error_docref(NULL TSRMLS_CC, E_WARNING, "Did not found column name
'%s' in the defined columns; it will not be bound", param->name);
I believe it should be replaced by something like the following:
pdo_raise_impl_error(stmt->dbh, stmt, "?????", "Did not found column
name in the defined columns; it will not be bound" TSRMLS_CC);
I also believe "Did not found column name" is not proper english and
should either be "Did not find column name" or "Column name not found".
I also do not know the exact meaning of the error codes used in other
pdo_raise_impl_error like "HY093", so an appropriate errorcode for this
error should be inserted instead of the question marks.

Description:
------------
If you call bindColumn on a non existent column it will always create a
warning, no matter how the PDO object is configured to respond to errors
(ERRMODE_EXCEPTION, ERRMODE_SILENT, ERRMODE_WARNING).
I actually recreated this on PHP 5.3.1 and PHP 5.2.6-1+lenny8 (from
Debian Lenny repository) and have NOT tried it on 5.3.2. Since I was not
able to find any references for this bug on the web, I believe I might
be the first one to encounter it and it is propably not fixed as of PHP
5.3.2
Test script:
---------------
$pdo = new PDO('mysql:host=localhost;dbname=db', 'root', '');
$pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$statement = $pdo->prepare('SELECT id FROM aTable');
$statement->execute();
$field= NULL;
try
{
$statement->bindColumn('none_existent_field', $field,
PDO::PARAM_INT);
while ($statement->fetch( PDO::FETCH_BOUND ))
{
echo $field. "<br/>\n";
}
}
catch (PDOException $e)
{
echo "Database field not in result set!<br/>\n";
}
Expected result:
----------------
The string "Database field not in result set!<br/>\n";
Actual result:
--------------
A warning:
<b>Warning</b>: PDOStatement::bindColumn() [<a
href='pdostatement.bindcolumn'>pdostatement.bindcolumn</a>]: Did not
found column name 'none_existent_field' in the defined columns; it will
not be bound in <b>/path/to/script.php</b> on line <b>10</b><br />
