4.0.2.52008-08-30
To load: (require (planet "snooze.ss" ("untyped" "snooze.plt" 2 (= 0))))
Available in repositories: 4.x

New features:

  • a completely new procedural query language that supports nested subqueries, expressions on columns, aggregate functions and DISTINCT, GROUP and HAVING clauses;
  • a new syntax wrapper for the query language, allowing briefer queries;
  • full support for nested transactions in PostgreSQL (including rollback of persistent structs to keep them synced with changes in the database);
  • an experimental audit trail feature (warning: the interface is likely to change in a future release).
  • persistent-structs are now serializable with scheme/serialize.

Known issues:

  • transaction support and pipelines have not been fully documented;
  • a bug in SQLite causes all queries with nested joins in them to fail: a solution to this problem is being worked on.
