## TYPO3 Fatal Error: No database selected! {#typo3-fatal-error-no-database-selected}

`typo3conf/LocalConfiguration.php` misses the database configuration.

If you've just updated from a version below TYPO3 8.7 , you are most probably missing new
configuration in your `AdditionalConfiguration.php` file. Since TYPO3 8.7 the
structure of the db connection configuration has changed.

Something like that will work in AdditionalConfiguration.php:

```
$GLOBALS['TYPO3_CONF_VARS']['DB']['Connections']['Default']['dbname'] = 'dbname';
$GLOBALS['TYPO3_CONF_VARS']['DB']['Connections']['Default']['host'] = '127.0.0.1';
$GLOBALS['TYPO3_CONF_VARS']['DB']['Connections']['Default']['user'] = 'username';
$GLOBALS['TYPO3_CONF_VARS']['DB']['Connections']['Default']['password'] = 'passwordtodb';

```
