I want to delete an entry in my custom module table, in a similar way to this select:

    $select = $this->getConnection()->select()->from(
        ['*' => $this->getMainTable()]
        'quote_ref = ?',

    $data = $this->getConnection()->fetchOne($select);

I am using the following code:

    public function deleteByRef($quote_ref = null)
        $delete = $this->getConnection()->delete();

And getting the following error:

1 exception(s):

Exception #0 (Exception): Warning: Missing argument 1 for Zend_Db_Adapter_Abstract::delete(), called in C:\laragon\www\websitestore\app\code\Website\Quote\Model\ResourceModel\Data.php on line 43 and defined in C:\laragon\www\websitestore\vendor\magento\zendframework1\library\Zend\Db\Adapter\Abstract.php on line 650

How can I pass parameters to the delete method?


Here is what worked for me:

$resource = $objectManager->get('Magento\Framework\App\ResourceConnection');
$connection = $resource->getConnection();
$myTable = $resource->getTableName('mytable');

    ['order_id = ?' => 10000]

Hope it helps.


If we take a look:


     * Deletes table rows based on a WHERE clause.
     * @param  mixed        $table The table to update.
     * @param  mixed        $where DELETE WHERE clause(s).
     * @return int          The number of affected rows.
    public function delete($table, $where = '');

As we can see, delete method needs at least one argument. In our case, we can try:

                ['quote_ref = ?', $quote_ref]
  • I got an error, Exception #0 (Zend_Db_Statement_Exception): SQLSTATE[HY093]: Invalid parameter number: no parameters were bound, query was: DELETE FROM ghm_udropship_vendor_shipping WHERE (vendor_id = ? ) AND (1). Can you please let me know. – sagar sapkota Jun 6 '17 at 8:00
  • You need to have the array key quote_ref = ? and the value $quote_ref in this example. Otherwise it treats the array as a list of different where clauses – Nathaniel Rogers Jan 18 at 23:07
