Slaq is a port of Stephan Zeiger's excellent ScalaQuery, a type-safe database query API for Scala, similar to FRM (Functional Relational Mapper) libraries like Slick and Quill.

Changes to-date:

• added support for Scala 2.13
• added support for multiple table (outer) joins, mirroring sql join syntax
• automatic mapping of user defined value classes to underlying primitve type
• take/drop queries are now cacheable
• map/flatMap Parameterscall has been renamed to Params
• threadLocalSession has been removed
• deprecated != conditional operator has been removed
• =~, =!, &, and | are now available as alternatives to ===, =!=, &&, and ||
• MS Access and Derby support have been removed
• myriad refactorings that improve performance compared to original implementation

It includes the following features:

• Session management based on JDBC Connections
• Type-safe queries based on a query monad and combinators
• Simple static and dynamic queries

The following database systems are directly supported for type-safe queries:

• PostgreSQL
• MySQL
• Microsoft SQL Server
• H2
• HSQLDB/HyperSQL
• Derby/JavaDB
• SQLite Accessing other database systems is possible, with a reduced feature set.
