# Deprecation: #85394 - Class CoreDatabasePdoHelper deprecated

See [forge#85394](https://forge.typo3.org/issues/85394)

## Description

The PHP class `\TYPO3\CMS\Core\Database\PdoHelper` and its static method
`importSql()` have been marked as deprecated.

## Impact

Using the method triggers a PHP `E_USER_DEPRECATED` error, the class will be removed in TYPO3 v10.

## Affected Installations

Instances with extensions calling `TYPO3\CMS\Core\Database\PdoHelper::importSql()`.
The extension scanner will find affected extensions.

## Migration

The method has been of limited use from an extension point of view. If needed by an extension,
the method should be copied over into extension code.
