SQLite3 Module ============== Maintainer Contact ------------------ Andreas Piening (Nickname: apiening) Requirements ------------ SilverStripe 2.4 or newer Installation ------------ copy the sqlite3 folder to your project root so that it becomes a sibling of cms, sapphire and co add this to your _config.php define('SS_DATABASE_CLASS','SQLiteDatabase'); you are done! Config ------ you can set the path for storing your SQLite db file or make use of the :memory: feature in sqlite3/_config.php like this: $databaseConfig = array( 'path' => '/some/path', 'memory' => true, ); make sure the webserver has sufficient privileges to write to that folder and that it is protected from external access. URL parameter ------------- If you're trying change a field constrain to NOT NULL on a field that contains NULLs it aborts the action 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 Tested stacks ------------- OSX leopard, XAMPP with PHP 5.3.0, SQLite3.6.3 Ubuntu, PHP 5.2.4, SQLite3.4.2 WinXP, XAMPP with PHP 5.3.0, SQLite3.6.16 Open Issues ----------- - SQLite3 may not work with certain modules as they are using custom SQL statements passed to the DB class directly ;( - there is no real fulltext search yet and the build-in search engine is not ordering by relevance, check out fts3 Things to note when using SQLite3 --------------------------------- - small, fast, zero configuration, single cross-platform disk file, comes with a CLI and In-Memory database feature - sometimes the only feasible solution when you don't have access to the usual DBMSs like MySQL - weakly and dynamically typed although this should have been caught in the adapter - does not fully implement SQL-92 standard, e.g. the ALTER TABLE syntax is limited to adding and renaming fields - references for sqlite are e.g. ADOBE (Photoshop Lightroom), Apple (Safari, Mail, iPod, iPhone) Mozilla (Firefox, Thunderbird), Google (Chrome) - if you are looking for a SQLite client for debugging, the SQLite plugin for firefox may be worth a try
