Foundations JDBC

A JDBC wrapper library that makes JDBC actually usable. Every column type modeled correctly across all supported databases, with full roundtrip support.

Getting Started

Add the dependency to your project:

Gradle

implementation("dev.typr.foundations:foundations-jdbc:version")

Maven

<dependency>
    <groupId>dev.typr.foundations</groupId>
    <artifactId>foundations-jdbc</artifactId>
    <version>version</version>
</dependency>

Language-specific DSL modules:

Gradle

// Kotlin DSL
implementation("dev.typr.foundations:foundations-jdbc-dsl-kotlin:version")

// Scala DSL
implementation("dev.typr.foundations:foundations-jdbc-dsl-scala_3:version")

Maven

<!-- Kotlin DSL -->
<dependency>
    <groupId>dev.typr.foundations</groupId>
    <artifactId>foundations-jdbc-dsl-kotlin</artifactId>
    <version>version</version>
</dependency>

<!-- Scala DSL -->
<dependency>
    <groupId>dev.typr.foundations</groupId>
    <artifactId>foundations-jdbc-dsl-scala_3</artifactId>
    <version>version</version>
</dependency>

Core Concepts

• Row Types & Parsers — Define how to read rows from a ResultSet with composable, type-safe parsers.
• Result Sets — Handle the full lifecycle of reading from a ResultSet.
• Fragments — Build SQL safely with type-checked parameters.
• Transactors — Manage connections and transactions.
