I'm trying to fetch a row with a where statement but for some reason it throws an error at me.
This is the line
$row = $this->getDbTable()->fetchRow("order = $order");
I've put a die(); before this line and it does die,
Then I've put a die(); after this line and the die() doesn't get executed but throws an error.
The error doesn't help me much it only says "An error occurred Application error", there's nothing in my php error log either.
Help!
Going by your comments, I would try doing the where part 'properly'? E.g.:
$select = $this->getDbTable()->select()->where('order = ?', $order);
$row = $this->getDbTable()->fetchRow($select);
What is the situation you are needing to select by order? Is there a primary key you can select by?
Update:
Given your comments, maybe use update directly:
$table = $this->getDbTable();
$data = array( 'order' => $order+1 );
$where = $table->getAdapter()->quoteInto('order = ?', $order);
$table->update($data, $where);

I try to update a really old extbase extension which is from another programmer. TYPO3-Version is 8.7.13
The following function in my Repository throws the error:
"Commands out of sync; you can't run this command now
Doctrine\DBAL\Driver\Mysqli\MysqliException thrown in file
/Volumes/web/src/typo3_src-8.7.13/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/Mysqli/MysqliStatement.php in line 249."
And this ist the function:
Public Function delete($standort, $month)
{
$m = date('m',$month);
$y = date('Y',$month);
$sql = "
DELETE FROM mytable
WHERE standort = ".$standort." AND FROM_UNIXTIME( monat, '%m' ) = $m AND FROM_UNIXTIME( monat, '%Y' ) = $y ";
$query = $this->createQuery();
$query->statement($sql);
$query->execute(TRUE);
}
with $query->execute(FALSE); no error is thrown but the sql is not executed. With $query->execute(TRUE); the error appears but the sql will be executed.
Can anybody help?
Thanks!
What about changing this statement to Doctrine? You can find the documentation here: https://docs.typo3.org/typo3cms/CoreApiReference/8.7/ApiOverview/Database/BasicCrud/Index.html#delete-a-row
I have a problem with a prepared statement, here is my code:
function query_array($table, $data) {
foreach ($data as $column => $value) {
$columns[] = sprintf("`%s` = '%s'", $column, $this->db->real_escape_string($value));
}
$column_list = join(',', $columns);
// Prepare the statement
$stmt = $this->db->prepare("UPDATE `?` SET ?");
$stmt->bind_param('ss', $table, $column_list);
// Execute the statement
$stmt->execute();
// Save the affected rows
$affected = $stmt->affected_rows;
// Close the statement
$stmt->close();
// ...
}
$this->db returns an object;
$table = 'settings'; (string)
$column_list: (string)
`title` = 'Socialsd',`captcha` = '0',`public` = '',`private` = '',`time` = '1',`perpage` = '10',`message` = '140',`mail` = '1',`inter` = '10000',`size` = '1048576',`format` = 'png,jpg,gif',`sizeMsg` = '1048576',`formatMsg` = 'png,jpg,gif,bmp',`censor` = '',`ad1` = '',`ad2` = ''
The error I'm getting is:
Fatal error: Uncaught exception 'ErrorException' with message 'You
have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near '?' at line
1' in C:\xampp\htdocs\new\includes\classes.php:256 Stack trace: #0

updateSettings->query_array('settings', Array) #1
C:\xampp\htdocs\new\index.php(42): PageMain() #2 {main} thrown in
C:\xampp\htdocs\new\includes\classes.php on line 256
I can't figure out what causes this, because trying the following works just fine:
$query = sprintf("UPDATE `%s` SET %s", $table, $column_list);
$result = $this->db->query($query);
Any help is appreciated.
Update 1: May I know why this has been down-voted? It would be nice to know.
Update 2: So I've removed the last bind ($column_list) and put in the statement the entire output of $column_list, so basically I was binding only the table name, and now I get another error:
Can't find file: '.\diary\#003f.frm' (errno: 22)
Now I'm really confused.
I have found the answer here: Use one bind_param() with variable number of input vars and also as #Jocelyn linked me, I've found that table names can't be binded. Can be closed.
In my Application_Model_DbTable_User, I have the following function:
public function deleteUser($username)
{
$this->delete('username = ' . (string) $username);
}
This function is being called from my AdminController, with this three lines of code.
$uname = $this->getRequest()->getParam('username');
$user = new Application_Model_DbTable_User();
$user->deleteUser($uname);
This error however, turns up.
Column not found: 1054 Unknown column 'test' in 'where clause'
With test being the user I am trying to delete.
This code is adapted from a previous code which deletes based on id, a INT field, which works perfectly fine. What am I doing wrong? I would be happy to give more detailed codes if needed. Thanks.
Your query isn't quoted:
$this->delete('username = ' . (string) $username);
This equates to:
WHERE username = test
If you use the where() method, it will do this for you:
$table->where('username = ?', $username);
Or (like the example in the docs):
$where = $table->getAdapter()->quoteInto('bug_id = ?', 1235);
$table->delete($where);
I have a function which is wanted to execute a statement like below:
UPDATE coupon_users SET status = status | '1' WHERE id IN ('3','4')
And in coupon_users model, I wrote a method like below do to:
/**
* #param array $ids #array(3,4)
* #param array $status #1
*/
public function updateStatus(array $ids, $status)
{
$result = $this->_db->query(
"UPDATE {$this->_name} SET status = status | ? WHERE id IN (?)",
array(
$status,
$ids
)
)->execute();
return $result;
}
But the query is always:
UPDATE coupon_users SET status = status | '1' WHERE id IN ('Array')
I don't know what am I wrong here, please help me, many thanks.
According to the PDO documentation (Zend_Db uses PDO as its DB access backend):
You cannot bind multiple values to a single named parameter in, for
example, the IN() clause of an SQL statement.
So, you'll probably need to prepare a bit further your query, so that it contains as many markers as elements in the array. A possible solution could be the following:
// Compose the query
$queryToExecute = "UPDATE {$this->_name} SET status = status | ? WHERE id IN (";
$questionMarks = array();
for ($id in $ids) {
$questionMarks[] = '?';
}
$queryToExecute .= implode(',', $questionMarks);
$queryToExecute .= ')';
// $queryToExecute should have the format "UPDATE ... WHERE id IN (?,?,?,...?)"
// Execute it
$result = $this->_db->query(
$queryToExecute,
array($status, $ids)
)->execute();
Hope that helps,
try:
public function updateStatus(array $ids, $status)
{
$result = $this->_db->query(
"UPDATE {$this->_name} SET status = ? WHERE id IN (?)",
array(
$status,
implode(',',$ids)
)
)->execute();
return $result;
}
Update:
Have you tried?:
$this->_db->update($this->_name, array('status'=>$status), array('id IN (?)'=>$ids));
I haven't tested it, it also depends on what $this->_db is an instance of
http://framework.zend.com/manual/en/zend.db.adapter.html#zend.db.adapter.write.update
Try this..
public function updateStatus(array $ids, $status)
{
$inarray= implode(',',$ids);
$result = $this->_db->query(
"UPDATE {$this->_name} SET status = status | ? WHERE id IN (?)",
array(
$status,
$inarray
)
)->execute();
return $result;
}
Its working fine for me.
$existingImagesIds = array(1, 2, 3, 7);
$where = $pImgModel->getAdapter()->quoteInto("id in (?) ", $existingImagesIds);
$pImgModel->update(array('status' => '0'), $where);
I cant see my error of Sql. It cuts my queries, and the error is meaningless except it informs there is an error.
Like
error in statement "select * from o.."
how can I get full query, so i can investigate how the error occured?
I previously wrote a sql function that throws debugging string if sql has error. I though zend'ers have needed and there should exists a code:
if(($error = mysql_error($conn)){
$cagiri=debug_backtrace();
$i=count($cagiri);
And says
[Caller__Function__] => dbSave
[Caller__Class__] => classBasic
[Arguments] => Array
(
[0] => function : loadLinks
[1] =>
[1] => sql error: Duplicate entry 'http://www.istanbulboncugu.com/Lokma' for key 'url'
[2] => query: insert into downloadLinks set `title`= 'Lokma : İstanbul - Avrupa', `url`= 'http://www.istanbulboncugu.com/Lokma', `site`= 'rssSehirFirsati', `status`= 'new'
So I dont dig 30 query, if there is error,
Error string shows function that composed the query. Etc.
I think Zend have lacks that kind of awareness.
I know zend not prefers hard and log path against smart ways ?!?
I start using that code, if there is error.
function results($q){
$results = Array();
try{
$results = $this->_db->query($q)->fetchAll();
}catch(Exception $e){
var_dump($q);
die($e->getMessage());
}
return $results;
}
If you are using Zend_Db_Select you can get the full created query by doing
$select->__toString();
In reply to your comment, this is how you can get the SQL error message:
try {
$this->db->insert('Users', $array );
} catch (Exception $e){
echo $e->getMessage();
}
