composer require silverstripe/sqlite3
Either use the installer to automatically install SQLite or add this to your _config.php (right after "require_once("conf/ConfigureFromEnv.php");" if you are using _ss_environment.php)
$databaseConfig['type'] = 'SQLite3Database';
$databaseConfig['path'] = "/path/to/my/database/file";
Make sure the webserver has sufficient privileges to write to that folder and that it is protected from external access.
<?php
global $project;
$project = 'mysite';
global $database;
$database = 'SS_mysite';
require_once("conf/ConfigureFromEnv.php");
global $databaseConfig;
$databaseConfig = array(
"type" => 'SQLite3Database',
"server" => 'none',
"username" => 'none',
"password" => 'none',
"database" => $database,
"path" => "/path/to/my/database/file",
);
Again: make sure that the webserver has permission to read and write to the above path (/path/to/my/database/, 'file' would be the name of the sqlite db file)
If you're trying to change a field constrain to NOT NULL on a field that contains NULLs dev/build fails because it might corrupt existing records. In order to perform the action anyway add the URL parameter 'avoidConflict' when running dev/build which temporarily adds a conflict clause to the field spec. E.g.: http://www.my-project.com/?avoidConflict=1
