TRUNCATE table + Zend Framework

I'm doing it:

$data = array('coords'   => $district->getCoords(),
    'id'       => $district->getId(),
    'fid'      => $district->getFid(),
    'wijziging'=> $district->getWijziging(),
    'nieuwnr'  => $district->getNieuwnr(),
    'naam'     => $district->getNaam(),
    'wijk'     => $district->getWijk(),
    'wijknr'   => $district->getWijknr(),
    'objectid' => $district->getObjectid(),
    'area'     => $district->getArea(),
    'len'      => $district->getLen(),
);


$this->_dbTable->insert($data);

_dbTable → links to the "Districts" table.

Now I want to clear the table first before inserting data.

How can i do this?

Try to get an adapter if you really need to trim the table



$this->_dbTable->getAdapter()->query('TRUNCATE TABLE '.$this->_dbTable->info(Zend_Db_Table::NAME));

Try:

$this->_dbTable->delete("1=1");


Take care of your problem. 1 = 1 will match all records, deleting them. As far as I know, there is no truncation method in Zend_Db or PDO.

@Rikesh is right, take a moment to browse the faq , after which you will get much better help.

Extend Zend_Db_Table_Abstract and add:

/**
 * Remove all contents of the table
 * @return this
 */
public function truncate()
{
    $this->getAdapter()->query('TRUNCATE TABLE `' . $this->_name . '`');

    return $this;
}

If you are using Zend Framework 2 with tableGateway, the process is very similar.

    $query = $this->tableGateway->getAdapter()->query('TRUNCATE TABLE '.$this->tableGateway->getTable());
    $query->execute();
