Bug #49268 PDO::Execute and SQLite CHECK constarints quoting INTS
Submitted: 2009-08-15 15:24 UTC Modified: 2009-08-15 16:36 UTC
From: face at dfhu dot org Assigned:
Status: Not a bug Package: SQLite related
PHP Version: 5.2.6-2ubuntu4.2 OS: Ubuntu
Private report: No CVE-ID: None
 [2009-08-15 15:24 UTC] face at dfhu dot org
Description:
------------
PDO::Execute quotes integers even though this will cause problems in SQLite. SQLite has type affinity and sometimes requires hard checks.

that is "(product_id) VALUES ('1')" is NOT the same as "(product_id) VALUES (1)";


Thanks!

Reproduce code:
---------------
$pdo=new PDO("sqlite:./db/sales.sqlite");
$pdo->setAttribute(PDO::ATTR_ERRMODE,
		   PDO::ERRMODE_EXCEPTION);
$sql="
CREATE TABLE IF NOT EXISTS sales (
product_id INT
 CHECK(typeof(product_id) = 'integer')
)";
$pdo->query($sql);

$sql="
INSERT INTO sales
 (product_id)
   VALUES
 (:product_id)";
$statement=$pdo->prepare($sql);

// this will throw a integrity constraint error
$statement->execute(Array(":product_id"=>1));


Expected result:
----------------
I do not expect to see an exception thrown, i expect PDO::execute() to not quote integers in SQLite. Thus there should be no output.

Actual result:
--------------
Uncaught exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 19 constraint failed'

The version number was not accurate. 5.2.6-2ubuntu4.2 is the version as shown by phpinfo();

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. 

Thank you for your interest in PHP.


This was fixed in 5.3.0 already, see bug #42443
