Add SQLITE Dialect by sdelamo · Pull Request #3830 · micronaut-projects/micronaut-data

sdelamo · 2026-04-24T17:01:59Z

This pull request adds a new dialect - SQLITE. The ANSI dialect could almost be used, but there are some small differences that I consider merit a separate dialect for SQLITE.

Most classes added in this Pull-request are tests. This PR adds a test module. test-suite-data-jdbc-sqlite. I ported the tests in data-jdbc/src/test/groovy/io/micronaut/data/jdbc/h2 from Spock to JUNIT and changed the test to use the SQLITE dialect.

This change adds a new entry to `Capability`. BATCH_INSERT. It also modifies the API of `ConnectionCapablities`, adding the method `public boolean supports(ConnectionCapabilities.Capability capability, Supplier<String> databaseProductNameSupplier)`. So that the API can be invoked with a `java.sql.Connection` or a `io.r2dbc.spi.Connection`. This change modifies the `DefaultConnectionCapabilities` implementation to specify that SQL Server does not support BATCH_INSERT. This business logic was already specified in `AbstractSqlRepositoryOperations::isSupportBatchIsert(PersistentEntity, Dialect)`. SQLite does not support batch inserts either. This change modifies `SqliteConnectionCapabilities` to specify that and adds a test which verifies that with the new Capability check, a `saveAll` method invocation is possible with SQLite.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Adds first-class SQLite support across Micronaut Data by introducing a Dialect.SQLITE, updating SQL/runtime infrastructure to accommodate SQLite-specific behavior, and adding a dedicated JDBC SQLite test suite plus documentation and example updates.

Changes:

Added Dialect.SQLITE plus SQLite-oriented SQL generation tweaks (e.g., DEFAULT VALUES, identity/INTEGER handling, batch rules).
Introduced a new test-suite-data-jdbc-sqlite module with extensive coverage for repositories, joins, multitenancy, generated values, etc.
Updated ConnectionCapabilities API to be supplier-based (usable for JDBC + R2DBC) and refreshed docs/examples accordingly.

SQLite doesn't support CONCAT(...) by default. This query will fail on SQLite; use SQLite-compatible concatenation (e.g., '%' || :partialName || '%'). Also consider dropping the trailing ; in the SQL string to avoid driver-specific parsing issues.

Changing the SPI contract from supports(Capability, Connection) to supports(Capability, Supplier<String>) is a source/binary breaking change for any external ConnectionCapabilities implementations loaded via Java SPI. To preserve compatibility, consider keeping the original supports(Capability, Connection) as the primary method (or at least as an abstract method) and adding the supplier-based method as a default method (e.g., defaulting to true), then migrate internal call sites to prefer the supplier overload. That way existing third-party implementations continue to compile/run unchanged while new implementations can override the supplier-based method for JDBC/R2DBC parity.

INSERT INTO <table> DEFAULT VALUES is not supported by all SQL dialects (notably MySQL/MariaDB typically require INSERT INTO <table> () VALUES ()). Since this query builder is dialect-agnostic, emitting DEFAULT VALUES unconditionally when columns is empty risks breaking inserts on those dialects. Consider generating dialect-specific SQL here (e.g. DEFAULT VALUES for SQLite/Postgres/H2/SQL Server/Oracle, but () VALUES () for MySQL/MariaDB).

Done in commit 1f93edc. MySQL now generates INSERT INTO <table> () VALUES () while all other dialects (SQLite, Postgres, H2, SQL Server, Oracle, ANSI) continue to use INSERT INTO <table> DEFAULT VALUES.

+    String driverClassName() default "org.sqlite.JDBC";
+
+    String url() default "jdbc:sqlite:file:%s?mode=memory&cache=shared&foreign_keys=ON&busy_timeout=5000";


The default url() contains a %s format placeholder, but in SQLiteDBPropertiesTestPropertyProviderFactory the URL is passed through as-is (no String.format). This likely yields a literal database name of %s, causing unrelated test classes/contexts to share the same in-memory SQLite database (cache=shared) and potentially introducing test interference/flakiness. Consider either (1) formatting the URL using name() (or a per-test unique suffix), or (2) switching to a Micronaut placeholder-based value (e.g. using ${...}), or (3) removing the placeholder and using a per-test temp file URL like the SQLiteTestingPropertyProvider does.

This PR changes the public ConnectionCapabilities API/SPI (adds a new primary method signature and shifts implementers to Supplier<String>), which is a significant change beyond 'Add SQLITE Dialect' as described in the PR metadata. Please update the PR description to explicitly call out this API/SPI change (and any compatibility expectations), or split it into a separate PR if the intent is to keep this SQLite-focused.

This test uses reflective access (setAccessible(true)) to reach into AbstractTransactionSpec. This can break under stricter JVM access controls (JPMS), security policies, or future refactors of the base test class. Prefer exposing the ApplicationContext via a protected accessor on AbstractTransactionSpec (if possible), or restructure the test to receive the context through injection/constructor setup rather than reflection.

The default url() contains a %s placeholder, but SQLiteDBPropertiesTestPropertyProviderFactory currently passes it through without formatting. With mode=memory&cache=shared, this also risks multiple tests sharing the same in-memory DB name (leading to cross-test interference/flakiness). Format the URL using name() (or a unique per-test value), or remove the placeholder and generate a unique URL in the property provider.

SQLite DEFAULT (expr) has restrictions and commonly rejects non-constant / non-deterministic expressions in defaults; the randomblob(...)/random() UUID expression is likely to break schema generation at runtime. Consider not emitting a DB-side UUID default for SQLite and instead relying on Micronaut Data UUID auto-population/application-side generation, or implement UUID generation via triggers where supported.

createProperties() creates a fresh temp SQLite database per test invocation, so bookWasDropped() doesn't actually validate CREATE_DROP behavior on the same database—it only observes an empty brand-new DB. Reuse the same DB file across both tests (e.g., @TestInstance(PER_CLASS) + shared temp file) or explicitly assert that the schema was dropped (e.g., by expecting a table-missing error) after closing the first context.
