Description:
------------
I believe I have found a bug

PDO - 0.3
PDO_SQLITE - 0.3

If I retrieve the results of PRAGMA table_info('user_policy') with fetchAll, the type column in the array that is returned is mangled.  It appears to me that spaces are sucked out.

Notice the user_policy_no data type below, and the output of PHP's print_r on the array that is returned.  "INTEGER UNSIGNED" is turned into "INTEGERUNSIGNED"

Here is my SQL:

CREATE TABLE user_policy (
  user_policy_no INTEGER UNSIGNED NOT NULL ,
  name VARCHAR(80) NOT NULL,
  manager_zone_access_level CHAR(1) NULL,
  manager_active_yn CHAR(1) NOT NULL DEFAULT '1',
  manager_gui_access_level_lkup CHAR(1) NULL,
  active_yn CHAR(1) NULL,
  creation_dte DATETIME NULL,
  last_modified_dte DATETIME NULL,
  PRIMARY KEY(user_policy_no)
)

Here is a dump of the array:
    [0] => Array
        (
            [cid] => 0
            [0] => 0
            [name] => user_policy_no
            [1] => user_policy_no
            [type] => INTEGERUNSIGNED
            [2] => INTEGERUNSIGNED
            [notnull] => 99
            [3] => 99
            [dflt_value] =>
            [4] =>
            [pk] => 1
            [5] => 1
        )

Reproduce code:
---------------
CREATE TABLE user_policy (
  user_policy_no INTEGER UNSIGNED NOT NULL ,
  name VARCHAR(80) NOT NULL,
  manager_zone_access_level CHAR(1) NULL,
  manager_active_yn CHAR(1) NOT NULL DEFAULT '1',
  manager_gui_access_level_lkup CHAR(1) NULL,
  active_yn CHAR(1) NULL,
  creation_dte DATETIME NULL,
  last_modified_dte DATETIME NULL,

  PRIMARY KEY(user_policy_no)
)

$field_result = $db->prepare("PRAGMA table_info('user_policy')");
$field_result->execute();
print_r($field_result->fetchAll());


Expected result:
----------------

Did you try this using the sqlite3 command line tool?
What does it show for that column?
 [2005-04-22 07:35 UTC] tom at supertom dot com
Yes, sorry I didn't post that info previously.  The sqlite3 command line tool shows the data type correctly.  "INTEGER UNSIGNED"

I will do more testing on it today and report my findings.
 [2005-04-22 09:24 UTC] tom at supertom dot com
I am mistaken!  The sqlite3 client DOES display the same problem!  I'll report this to the SQLite folks.  Sorry for the confusion, but hopefully this will help others in the future.

Thanks,

Tom
