Accessing the Database¶
The TYPO3 database should always be accessed using the QueryBuilder of doctrine.
The TYPO3\CMS\Core\Database\ConnectionPool
class can be used to create
a \TYPO3\CMS\Core\Database\Query\QueryBuilder
instance:
$queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable('tablename');
See the Database Access API documentation for more details.
