[Experimental] More powerful queries (#215) 
* Initial attempt at Lateral joins

* Fix lateral queries for Inner and Left joins. Remove for Full and Right as this is apparently illegal(who knew). Add TypeError on Full and Right joins. Update on clause to use a custom constraint instead of relying on ToFrom.

* Fix typo leading to erroneous ToFrom instance

* Implement non-recursive CTE's

* add withRecursive; cleanup whitespace

* Fix multiple recursive CTEs. Apparently the spec just wants RECURSIVE if any of the queries are recursive.

* Add test to verify that a CTE can reference a previously defined CTE

* Update with/Recursive to return an element of a from clause to allow for joins against CTEs

* Modify set operations to use a custom data type + typeclass + typefamily to allow direct use of SqlQuery a in set operation and to allow recursive cte's to unify syntax with SqlSetOperation. Added lowercase names for set operations. If we can migrate off the constructor names we may be able to simplify the implementation.

* Fixed haddock documentation issue from v3.3.4.0 and added documentation
for new features introduced by v3.4.0.0

* fixed comments that were changed while debugging haddock build

* Cleanup formatting in From per PR. Cleanup ValidOnClause, added documentation and reduced the number of instances

* Update src/Database/Esqueleto/Experimental.hs

6.7 KiB
Raw Blame History

3.4.0.0

  • @belevy, @charukiewicz
    • #215
      • Added support for common table expressions (with, withRecursive)
      • Added support for lateral JOINs with updated example (Example #6)
      • Deprecated SelectQuery, removing the neccessity to tag SqlQuery values
      • Deprecated use of data constructors for SQL set operations (replaced with functions)
      • Refactored module structure to fix haddock build (fixes build from 3.3.4.0)

3.3.4.1

  • @maxgabriel
    • #214
      • Add suggested hlint rules for proper isNothing usage

3.3.4.0

  • @parsonsmatt
    • #205

      • More documentation on the Experimental module

      • Database.Esqueleto.Experimental now reexports Database.Esqueleto, so the new "approved" import syntax is less verbose. Before, you'd write:

        import Database.Esqueleto hiding (from, on)
import Database.Esqueleto.Experimental

        Now you can merely write:

        import Database.Esqueleto.Experimental

        Users will get 'redundant import' warnings if they followed the original syntax, the solution is evident from the error message provided.
