不是通过 ext_tables.sql .
您可以使用扩展管理器信号槽，并在安装扩展之后在那里执行查询 ext_localconf.php 您的分机号码：

call_user_func(function($extensionKey) {
        $signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\SignalSlot\Dispatcher::class);
        $signalSlotDispatcher->connect(
            \TYPO3\CMS\Extensionmanager\Service\ExtensionManagementService::class,
            'hasInstalledExtensions',
            function($keyOfInstalledExtension) use ($extensionKey) {
                if ($extensionKey !== $keyOfInstalledExtension) {
                    return;
                }
                \Vendor\MyExt\Hooks\ExtensionManager::postInstallExtension();
            }
        );
    }
}, $_EXTKEY);
