Funciones de SQLite (PDO_SQLITE)


PDO_SQLITE es un controlador que implementa la interfaz Objetos de Datos de PHP (PDO, siglas en inglés de PHP Data Objects) para habilitar el acceso a bases de datos de SQLite 3.


PDO_SQLITE permite usar cadenas aparte de flujos junto con PDO::PARAM_LOB.


El controlador PDO_SQLITE PDO está habilitado por omisión. Para deshabilitarlo, se puede usar --without-pdo-sqlite[=DIR], donde el parámetro opcional [=DIR] es el directorio base de instalación de sqlite. A partir de PHP 7.4.0 se requiere » libsqlite ≥ 3.5.0. Anteriormente, si libsqlite incluido podría haberse usado en su lugar, por omisión, si [=DIR] era omitido.

If you receive an error while trying to write to a sqlite database (update, delete, drop):

Warning: PDO::query() [function.query]: SQLSTATE[HY000]: General error: 1 unable to open database

The folder that houses the database file must be writeable.

With PDO SQLite driver, calculation within an SQL with multiple ? may not get results as you expect.

// ....
$stmt = $PDO->prepare('SELECT * FROM `X` WHERE `TimeUpdated`+?>?');
$stmt->execute([3600, time()]);
$data = $stmt->fetchAll();

To get the right results, you have more than 3 solutions.

1. Change 'SELECT * FROM `X` WHERE `TimeUpdated`+?>?' to 'SELECT * FROM `X` WHERE `TimeUpdated`>?' and do the math using Php (ie: $stmt->execute([time()-3600]); ).

2. Use PdoStatement::bindParam or PdoStatement::bindValue, and set the parameter type to PDO::PARAM_INT.

3. Change 'SELECT * FROM `X` WHERE `TimeUpdated`+?>?' to 'SELECT * FROM `X` WHERE `TimeUpdated`+?>?+0', here '?+0' may be replaced by another math function or another calculation, such as 'abs(?)', you can even wrap both ? with a math calculation.

Instead of compiling an old version of SQLite to create a database using an older database format that the version of SQLite bundled with PDO can handle, you can (much more easily) just run the query "PRAGMA legacy_file_format = TRUE;" BEFORE creating the database (if you have an existing database, run ".dump" from the sqlite shell on your database, run the sqlite shell on a new database, run the PRAGMA, then paste the contents of the .dump). That will ensure SQLite creates a database readable by SQLite 3.0 and later.

Note that as of the date of this post, PDO_SQLITE will not interact with database files created with the current version of the SQLite console application, sqlite-3.3.6.

It is currently necessary to obtain version 3.2.8, available from but only by entering the URI manually, as there is no link. Go to and find the URI of the version you're looking for, then make the appropriate version number substitution.
