Question

我的表格如下：

CREATE TABLE data.brand_list
(
  id bigserial NOT NULL,
  brand_name text,
  created_at timestamp with time zone DEFAULT now(),
  ghost boolean,
  CONSTRAINT brand_list_id_pkey PRIMARY KEY (id)
)

它也有序列：

 CREATE SEQUENCE data.brand_list_id_seq
 INCREMENT 1
 MINVALUE 1
 MAXVALUE 9223372036854775807
 START 649
 CACHE 1;
 ALTER TABLE data.brand_list_id_seq

我在Zend模型中的代码：

public function addRow(BrandList $brandList)
{
    $data = array(
        'id' => $brandList->id,
        'brand_name' => $brandList->brand_name,
        'created_at' => $brandList->created_at,
        'ghost' => $brandList->ghost,
    );

    $id = (int)$brandList->id;
    if ($id == 0) {
        unset($data['id']);
        $row = $this->tableGateway->insert($data);
        var_dump($this->tableGateway->getLastInsertValue());die;
        return $id;
    } else {
        if ($this->findOne($id)) {
            $this->tableGateway->update($data, array('id' => $id));
        } else {
            throw new \Exception('Form id does not exist');
        }
    }
}

并且$ row总是返回int（1），$ this-＆gt; tableGateway-＆gt; getLastInsertValue（）返回NULL。我究竟做错了什么？我已经尝试了一切......没有运气。

Answer 1

您可以尝试原始查询，看看您是否获得了所需的结果。

  $adapter = $this->tableGateway->getAdapter();

$rowset = "SELECT MAX(ID)...";

$resultset = $adapter->query($rowset,array());

$rowData = $resultset->toArray();
return $rowData;

OR

use Zend\Db\Sql\Sql;
use Zend\Db\Sql\Select;
Use Zend\Db\Sql\Expression;    
$adapter = $this->tableGateway->getAdapter();
    $sql = new Sql($adapter);
    $select = $sql->select();
    $select->from('table_name')->columns(array('id' => new Expression('max(id)') ));
    $selectString = $sql->getSqlStringForSqlObject($select);
    $results = $adapter->query($selectString, $adapter::QUERY_MODE_EXECUTE);
    $resultSet = new ResultSet();
    $resultSet->initialize($results);
    return $resultSet->toArray();

Answer 2

嗯，我发现也许不是太优雅的解决方案，但它对我有用。我发现了什么 - Zend 2有postgres序列的问题。这是我的解决方案：

$sql = "SELECT nextval('data.brand_list_id_seq') nextval";
        $resultSet = $this->tableGateway->getAdapter()->getDriver()->getConnection()->execute($sql);
        foreach ($resultSet as $item) {
            $data['id'] = $item['nextval'];
        }
        $this->tableGateway->insert($data);

        return $data['id'];

您应该将以上代码应用于模型插入方法。

Answer 3

尝试$this->tableGateway->lastInsertValue;
而不是$this->tableGateway->lastInsertValue();

ZEND2 - lastInsertValue返回NULL
