phpnomad/sqlite-integration

phpnomad/sqlite-integration implements phpnomad/db's query builders and table strategies for SQLite via PDO. It opens its own connection (configured by DSN), generates SQLite-flavored SQL, and exposes the same strategy interfaces that phpnomad/mysql-integration does — so entity classes, repositories, and validation are portable between MySQL and SQLite.

The intended use case is the local-storage half of a desktop app whose server uses phpnomad/mysql-integration. Same models on both sides, only the strategy binding differs.

Installation

What This Provides

• A QueryBuilder and ClauseBuilder that emit SQLite-flavored SQL for SELECT, JOIN, GROUP BY, ORDER BY, LIMIT, OFFSET, and the full set of comparison operators (including IS NULL, IN, BETWEEN, and AND/OR groups)
• QueryStrategy, TableCreateStrategy, TableDeleteStrategy, TableExistsStrategy, and TableUpdateStrategy implementations covering insert, update, delete, query, estimated count, and schema management
• TableUpdateStrategy::syncColumns handles SQLite's limited ALTER — simple ADD/DROP COLUMN for the common case, transactional create-copy-drop-rename for affinity changes
• PdoDatabaseStrategy — a PDO-backed DatabaseStrategy that parses SafeMySQL-style placeholders (?n, ?s, ?i, ?d, ?a) so the builders speak the same language as the MySQL pipeline
• Connection — a thin PDO wrapper that turns on foreign keys and WAL journaling by default
• DatabaseDateAdapter that round-trips DateTime through the same Y-m-d H:i:s format the MySQL adapter uses
• A Database facade exposing parse(), query(), and lastInsertId() for the bound DatabaseStrategy

Requirements

• PHP 8.3+ with pdo and pdo_sqlite extensions
• phpnomad/db
• phpnomad/loader ^1.0 || ^2.0

This package supplies its own DatabaseStrategy (PdoDatabaseStrategy) — unlike phpnomad/mysql-integration, you do not need a separate driver package.

Usage

Add Initializer to your bootstrapper. The integration registers every builder, strategy, and adapter listed above.

By default the integration opens an in-memory database. Point it at a file by setting PHPNOMAD_SQLITE_DSN:

Handlers in phpnomad/db will then resolve QueryStrategy, QueryBuilder, ClauseBuilder, and the table strategies from this package.

SQLite vs MySQL

The strategy layer is dialect-aware; everything above it is not. A few practical differences to know about:

• No AUTO_INCREMENT keyword. Use INTEGER PRIMARY KEY (rowid alias) or pass AUTOINCREMENT as a column attribute for strictly-monotonic ids. The MySQL AUTO_INCREMENT attribute is translated automatically.
• Type affinity, not types. VARCHAR(255) and TEXT are the same thing in SQLite. MySQL types (BIGINT, LONGTEXT, DATETIME, BOOLEAN, etc.) are mapped to SQLite-canonical equivalents in CREATE TABLE.
• Limited ALTER TABLE. Adding and dropping columns work directly. Changing a column's type affinity triggers a transactional rebuild handled by TableUpdateStrategy.
• LIKE is case-insensitive by default for ASCII. Set PRAGMA case_sensitive_like = 1 if your app needs MySQL-like behavior.
• No ENGINE=InnoDB / CHARACTER SET= table options. Silently dropped.

Testing

The test suite covers placeholder semantics, query construction, clause composition, table lifecycle, schema migration, value safety against SQL injection, type translation, and full-stack scenarios.

Documentation

The phpnomad/db documentation at phpnomad.com covers table schemas, handlers, and how the query building pipeline fits together.
