Summary: PostgreSQL: cannot bind NULL value to statement
condition
Status: Open
Type: Bug
Package: PDO related
Operating System: Debian GNU/Linux 2.6.26-2-amd64

New Comment:
You should write "...WHERE :nullValue IS NULL" instead of ".. WHERE NULL IS
:nullValue", otherwise execute() fails with a syntax error.
I'm not sure your example would work anyway since passing a null value in a
bind parameter seems problematic, but at least it would fail because of PDO and
not because of the SQL itself :)

Sorry, I forgot to mention this only applies to binding a null value as part of
a condition. Value assignment works fine (fieldName = :nullValue), so it might
has to do something with the 'IS' keryword?

Description:
------------
It seems to be impossible to pass NULL value to a PDO PostgreSQL statement
neither with bindValue nor using '?'-format and
$statement->execute(array(null)).
Test script:
---------------
$pdo = new PDO('pgsql:host=localhost;port=5432;dbname=db', 'user', 'pass');
$statement = $pdo->prepare('SELECT \'ok\' WHERE NULL IS :nullValue');
$statement->bindValue(':nullValue', null, PDO::PARAM_NULL);
$statement->execute();
$result = $statement->fetchColumn(0);
var_export($result);
Expected result:
----------------
'ok'
Actual result:
--------------
false
