# Breaking: #75711 - Removed DB-related methods and TCA-related options from cObj

See [forge#75711](https://forge.typo3.org/issues/75711)

## Description

The following methods have been removed from `ContentObjectRenderer` without substitution:

-   `DBgetDelete()`
-   `DBgetUpdate()`
-   `DBgetInsert()`
-   `DBmayFEUserEdit()`
-   `DBmayFEUserEditSelect()`
-   `exec_mm_query()`
-   `exec_mm_query_uidList()`

The following TCA options have no effect anymore throughout the TYPO3 Core:

-   `$GLOBALS['TCA'][table]['ctrl']['fe_cruser_id']`
-   `$GLOBALS['TCA'][table]['ctrl']['fe_crgroup_id']`
-   `$GLOBALS['TCA'][table]['ctrl']['fe_admin_lock']`

## Impact

Calling any of the methods above directly will trigger a PHP fatal error.

## Affected Installations

Any TYPO3 installation using DB-related Frontend Administration with the obsolete functionality.
