# Deprecation: #77502 - Extbase: pre-parsing of queries removed

See [forge#77502](https://forge.typo3.org/issues/77502)

## Description

The following methods and properties within Extbase's persistence query comparison interface have been marked as deprecated:

-   `Comparison->setParameterIdentifier()`
-   `Comparison->getParameterIdentifier()`

## Impact

Calling any of the methods above will trigger a deprecation log entry.

## Affected Installations

Any TYPO3 installation using custom logic inside Extbase's own persistence layer with parameters and placeholders within
`Typo3DbBackend` or `Typo3DbQueryParser` and actively overwriting parameter identifiers within Extbase.

## Migration

Usage of these methods can be replaced by simply using the `DataMapper->getPlainValue()` functionality.
