Bug description: bind NULL variables generates warning
Description:
------------
when binding explicit null value there is no problem (see the
workarround), but, when the null value is from variable there is a problem
(the example is stupid, but is the simplest one representing the problem)
Reproduce code:
---------------
CREATE TABLE nullproblem (i integer);
<?
$conn = pg_connect('dbname=test');
$temp1 = null;
$param_list = array($temp1, $temp1, $temp1, );
/*******************
workarround:
$param_list = array(is_null($temp1)?null:$temp1,
is_null($temp1)?null:$temp1, is_null($temp1)?null:$temp1, );
****************/
pg_prepare($conn, 'test', 'INSERT INTO nullproblem VALUES (case when
$2::int IS NULL then $3::int else $1::int end)');
pg_execute($conn, 'test', $param_list);
?>
Expected result:
----------------
nothing special
Actual result:
--------------
Warning: pg_execute(): Query failed: ERROR: invalid input syntax for
integer: "" in test.php on line 10
