# Deprecation: #78225 - Legacy PreparedStatements within Extbase

See [forge#78225](https://forge.typo3.org/issues/78225)

## Description

Extbase has a way to set raw statements with PreparedStatements based on the legacy DatabaseConnection a.k.a. `TYPO3_DB`.
This functionality has been marked as deprecated.

## Impact

Calling a query within Extbase with `$query->setStatement($preparedStatement)` using a
`\TYPO3\CMS\Core\Database\PreparedStatement` object will trigger a deprecation log entry.

## Affected Installations

Any TYPO3 extension with Extbase functionality using custom prepared statements with the legacy database API.

## Migration

Use the same method `setStatement()` and provide a QueryBuilder object or a Statement object based on Doctrine DBAL.
