Use when you need programmatic JDBC in Micronaut — pooled DataSource, parameterized SQL, io.micronaut.transaction.annotation.Transactional, batching, and domain exception translation. This should trigger for requests such as Review JDBC or SQL data access in a Micronaut project; Improve transactions and parameter binding for Micronaut JDBC; Translate SQLException to domain exceptions or stream large result sets; Fix self-invocation bypassing @Transactional in Micronaut; Review Hikari or pooled…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Micronaut JDBC — programmatic SQL Apply programmatic JDBC patterns in Micronaut with safe SQL and clear transactions. **What is covered in this Skill?** - Injected javax.sql.DataSource (Hikari-backed with micronaut-jdbc-hikari) and try-with-resources for Connection / PreparedStatement - PreparedStatement with bind parameters — never string concatenation - Mapping ResultSet rows to Java records (dedicated mapRow method) - Safe single-row queries with Optional<T>; never assume rs.next() succeeds - SQLException translation to domain exceptions (catch-translate-rethrow) - Streaming large result sets with setFetchSize to avoid OOM - Batch updates with addBatch / executeBatch for bulk inserts - @Transactional service boundaries and TransactionDefinition.Propagation (e.g. REQUIRES_NEW for independent commits) - Self-invocation pitfall: call transactional collaborators through injected beans, not this.method() - SQL text blocks for multi-line SQL (upserts, dialect-specific clauses) - When to prefer Micronaut Data (`@512`) vs raw JDBC **Scope:** Apply recommendations based on the reference rules and good/bad code examples. ## Constraints …

How to install
mdr add jabrena/plinth/511-frameworks-micronaut-jdbc@sha256:7f75c46c293cfac8The line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
