Question

我想使用Zend \ Db \ Sql \ Insert插入一些数据，选项 ON DUPLICATE KEY UPDATE

其实我使用这种查询：

INSERT INTO `user_data` (`user_id`, `category`, `value`) 
VALUES (12, 'cat2', 'my category value')
 ON DUPLICATE KEY UPDATE `user_id`=VALUES(`user_id`), `category`=VALUES(`category`), `value`=VALUES(`value`);

与

$this->dbAdapter->query($sql, Adapter::QUERY_MODE_EXECUTE);

但我如何使用 Zend \ Db \ Sql \ Insert 生成上述查询？

感谢任何建议。干杯

也许此解决方案可以帮助您。

public function insertOrUpdate(array $insertData, array $updateData)
{
$sqlStringTemplate = 'INSERT INTO %s (%s) VALUES (%s) ON DUPLICATE KEY UPDATE %s';
$adapter = $this->tableGateway->adapter; /* Get adapter from tableGateway */
$driver = $adapter->getDriver();
$platform = $adapter->getPlatform();

$tableName = $platform->quoteIdentifier('table_name');
$parameterContainer = new ParameterContainer();
$statementContainer = $adapter->createStatement();
$statementContainer->setParameterContainer($parameterContainer);

/* Preparation insert data */
$insertQuotedValue = [];
$insertQuotedColumns = [];
foreach ($insertData as $column => $value) {
$insertQuotedValue[] = $driver->formatParameterName($column);
$insertQuotedColumns[] = $platform->quoteIdentifier($column);
$parameterContainer->offsetSet($column, $value);
}

/* Preparation update data */
$updateQuotedValue = [];
foreach ($updateData as $column => $value) {
$updateQuotedValue[] = $platform->quoteIdentifier($column) . '=' . $driver->formatParameterName('update_' . $column);

}

/* Preparation sql query */
$query = sprintf(
$sqlStringTemplate,
$tableName,
implode(',', $insertQuotedColumns),
implode(',', array_values($insertQuotedValue)),
implode(',', $updateQuotedValue)
);

$statementContainer->setSql($query);
return $statementContainer->execute();
}

我做了这段代码： Sql \ Insert

的扩展类

它正在工作，但我想我需要点亮它。因为我只是从Zend \ Db \ Sql \ Insert base更新“prepareStatement”和“getSqlString”的最新行。

您可以在https://github.com/remithomas/rt-extends
