Codeigniter database update - mysql

Question

The table is like this
and I want to update DecryptionDate by specify ArchiveID and RecipientID
this is my code
$this->load->database();
$date = date("Y-m-d H:i:s");
$data = array('DecryptionDate' => $date);
$array = array('ArchiveID'=>$archiveID.'','RecipientID'=>$userID.'');
$this->db->where($array);
$this->db->update('log', $data);
if ($this->db->affected_rows() > 0) {
echo "SUCCESS";
} else {
echo "FAIL";
}
my problem is I can update the data only when $archiveID is 911 and $userID is test01 but the program fail to update when $archiveID is 911 and $userID is test02
after added echo $this->db->last_query(); I've got
UPDATE log SET DecryptionDate = '2011-11-16 20:01:39' WHERE ArchiveID = '911' AND RecipientID = 'test01'
when ArchiveID is test01 and the update is SUCCESS
and
UPDATE log SET DecryptionDate = '2011-11-16 20:03:10' WHERE ArchiveID = '911' AND RecipientID = 'test02'
when ArchiveID is test02 and the update is FAIL
I've try this
$this->load->database();
$date = date("Y-m-d H:i:s");
$this->db->query('UPDATE log
SET DecryptionDate = \''.$date.'\'
WHERE ArchiveID = \''.$archiveID.'\' AND RecipientID = \''.$userID.'\'');
if ($this->db->affected_rows() > 0) {
echo "SUCCESS";
return TRUE;
} else {
echo "FAIL";
return FALSE;
}
but the result's still the same
and try check only the RecipientID like this
$this->load->database();
$date = date("Y-m-d H:i:s");
$this->db->query('UPDATE log
SET DecryptionDate = \''.$date.'\'
WHERE RecipientID = \''.$userID.'\'');
if ($this->db->affected_rows() > 0) {
echo "SUCCESS";
return TRUE;
} else {
echo "FAIL";
return FALSE;
}
make the update success with only record that match with the RecipientID but not with duplicate ArchiveID with other record
like this
Finally, I've test update with common php file with following code instead of via CI and also result is fail
$date = date("Y-m-d H:i:s");
$strSQL = "UPDATE log SET DecryptionDate = '".$date."' WHERE ArchiveID = '911' AND RecipientID = 'test02' ";
$objQuery = mysql_query($strSQL);
if( mysql_affected_rows($objQuery) != 0 )
{
echo (" SUCCESS ");
} else {
echo (" FAIL ");
}
so I think this must be database problem
here is the DB structure
and ArchiveID and RecipientID are index

Answer 1

The code looks fine. Please check that all your fields are correctly spelt, and values are as expected.
Try with a more verbose and debugging-friendly way like this, it should help you spot the problem (maybe the $userID contains a space, or something trivial like that). Call last_query() at the end to see if the query is really the one you wanted
//...
var_dump($archiveID);
var_dump($userID);
$this->db->where('ArchiveID',$archiveID);
$this->db->where('RecipientID',$userID);
$data = array('DecryptionDate' => $date);
$this->db->update('log', $data);
// call this to test the correct query; see if is what you intended
echo $this->db->last_query();

Answer 2

When you say no, do you mean no you cannot connect to MySQL or phpMyAdmin, or no, the query on test2 doesn't return any results? If the second one is true, can you do a select * and verify the fields existance? I cant help but think something may have happened to your data.

Answer 3

I try export the data from database and truncate it then import the data back, it can help, the problem solved.

Answer 4

I have use this code for checking update query status.
$this->db->where($array);
$status = $this->db->update('log', $data);
if($status)
echo 'Success';
else
echo 'Fail';
