* 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 Co-authored-by: charukiewicz <charukiewicz@protonmail.com> Co-authored-by: Matt Parsons <parsonsmatt@gmail.com>

synopsis: Type-safe EDSL for SQL queries on persistent backends.
|
|
description: @esqueleto@ is a bare bones, type-safe EDSL for SQL queries that works with unmodified @persistent@ SQL backends. Its language closely resembles SQL, so you don't have to learn new concepts, just new syntax, and it's fairly easy to predict the generated SQL and optimize it for your backend. Most kinds of errors committed when writing SQL are caught as compile-time errors---although it is possible to write type-checked @esqueleto@ queries that fail at runtime.

@persistent@ is a library for type-safe data serialization. It has many kinds of backends, such as SQL backends (@persistent-mysql@, @persistent-postgresql@, @persistent-sqlite@) and NoSQL backends (@persistent-mongoDB@). While @persistent@ is a nice library for storing and retrieving records, including with filters, it does not try to support some of the features that are specific to SQL backends. In particular, @esqueleto@ is the recommended library for type-safe @JOIN@s on @persistent@ SQL backends. (The alternative is using raw SQL, but that's error prone and does not offer any composability.)
|
|
.
|
|
Currently, @SELECT@s, @UPDATE@s, @INSERT@s and @DELETE@s are supported. Not all SQL features are available, but most of them can be easily added (especially functions), so please open an issue or send a pull request if you need anything that is not covered by @esqueleto@ on <https://github.com/bitemyapp/esqueleto>.

|
The name of this library means \"skeleton\" in Portuguese and contains all three SQL letters in the correct order =). It was inspired by Scala's Squeryl but created from scratch.
