php - TRUNCATE 表 + Zend 框架

Question

我这样做：

$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 -> 对我的表“地区”的引用。

现在我想在插入数据之前先清除表格。

我怎样才能做到这一点？

如果您确实需要截断表格，请尝试获取适配器

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

尝试：

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

应该照顾你的问题。1=1 将匹配所有记录，从而删除它们。据我所知，Zend_Db 或 PDO 中没有截断方法。

扩展 Zend_Db_Table_Abstract 并添加：

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

    return $this;
}

如果您将 Zend Framework 2 与 tableGateway 一起使用，则该过程非常相似。

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

<?php

            $this->resolveTable($this->table, $platform, $driver, $parameterContainer)

    }
}

$truncate = new Truncate('table');
return $this->getSql()->prepareStatementForSqlObject($truncate)->execute();

对于带有 tableGateway 的 Zend Framework 2/3：

    $adapter = $this->tableGateway->getAdapter();
    $sql = 'TRUNCATE TABLE '.$this->tableGateway->getTable();
 //Or, 
    $sql = 'DELETE FROM '.$this->tableGateway->getTable();

    $adapter->query($sql)->execute();
 // Or, 
    $adapter->createStatement($sql)->execute();
