Latest commit df27e4d Gregg Hernandez update to snapshot version for development.


Relate is a lightweight, blazing-fast database access layer for Scala that abstracts the idiosyncricies of the JDBC while keeping complete control over the SQL.


val ids = Seq(1, 2, 3)
sql"SELECT email FROM users WHERE id in ($ids)".asMap { row =>
  row.long("id") -> row.string("email")
val id = 4
val email = ""
sql"INSERT INTO users VALUES ($id, $email)".execute()


Relate is for developers who care about their database. It chooses not to sacrifice two things: SQL and performance.

  • SQL is already the best domain-specific language for querying relational databases. We don't need another. Ultimately, ORMs obscure the underlying queries and cause lots of headache.

  • In production situations, every millisecond matters. And while Relate may not be the prettiest face in the crowd, it does the best at managing large queries and large results.

With Relate, you can write your queries in the language nature intended, while interacting with the inputs and results in a high-level and performant way.


To use Relate with sbt, add this to your build.sbt or Build.scala:

libraryDependencies += "com.lucidchart" %% "relate" % "1.7.1"

resolvers += "Sonatype release repository" at ""
