-- | The main idea of bounded lists is to create lists with predetermined
-- maximum size.
--
-- BoundedList is a simple, fast and type safe approach to implementing
-- this idea. The implementation is based on inductive instances, making
-- it very easy to expand with new bounds. A new bound only requires one
-- instance of size and two instances of Less.
--
-- BoundedList works as follows. Every bound is build up by declaring a
-- data-type representing the new bound. The instance of size only
-- returns the size as an Int. The first instance of Less is for telling
-- the typechecker that this bound is greater than the largest smaller
-- bound. The second instance of Less is used by the typechecker to
-- construct a chain of instances if there is no hardcoded instance
-- available. This way the type checker can determine if a bound is
-- smaller/greater then any other bound.
--
-- This inductive approach gives the complexity O(n) on the number of
-- instances and very short type checking times compared to an O(n^2)
-- implementation.
--
-- BoundedList also comes with a few utility function for manipulation an
-- contructing bounded lists.
--
-- To be noted: Since each bound is a unique type: Explicit shrink and/or
-- grow is needed before using (==). BoundedList does not have an
-- instance of Ordering. (This might change)

-- | BoundedString represents the sql types; CHARACTER and CHARACTER
-- VARYING both defined in SQL 1992. BoundedString supports sizes in the
-- range [0,255] and 65535. Greater sizes and the sql type SQL_TEXT (SQL
-- 1992) will might be supported in the future.
--
-- The use of BoundedString together with HaskellDB enables feedback when
-- the length of a string exceeds the bound of a certain database field.
-- BoundedString also provides a layer of type safety against loss of
-- data due to sql string truncation when extracting and re-insert data
-- into fields with smaller bound.

-- | The record <tt>r</tt> has the field <tt>f</tt> if there is an instance

(!) :: Select f r a => r -> f -> a
-- | Adds the field from a one-field record to another record.
(#) :: Record (RecCons f a RecNil) -> (b -> c) -> (b -> RecCons f a c)

-- from an <a>Attr</a>.
(<<) :: Attr f a -> e a -> Record (RecCons f (e a) RecNil)
-- | Convenience operator for constructing records of constants. Useful
-- primarily with <tt>insert</tt>. <tt>f <<- x</tt> is the same as
-- <tt>f << constant x</tt>
(<<-) :: ShowConstant a => Attr f a -> a -> Record (RecCons f (Expr a) RecNil)

minus :: Query (Rel r) -> Query (Rel r) -> Query (Rel r)
-- | Creates a single-field record from an attribute and a table. Useful

copy :: HasField f r => Attr f a -> Rel r -> Record (RecCons f (Expr a) RecNil)
-- | Copies all columns in the relation given. Useful for appending the

--
-- will add all columns in <a>some_table</a> to the query.
copyAll :: RelToRec r => Rel r -> Record r

-- | The inverse of an Expr Bool.
_not :: Expr Bool -> Expr Bool
-- | The HaskellDB counterpart to the SQL LIKE keyword. In the expresions,
-- % is a wildcard representing any characters in the same position
-- relavtive to the given characters and _ is a wildcard representing one
-- character e.g.
--
-- <pre>
-- like (constant "ABCDEFFF") (constant "AB%F_F")
-- </pre>
--
-- is true while
--
-- <pre>
-- like (constant "ABCDEF") (constant "AC%F")
-- </pre>
--
-- is false.
--
-- Note that SQL92 does not specify whether LIKE is case-sensitive or
-- not. Different database systems implement this differently.

_length :: Expr String -> Expr Int
-- | Returns true if the expression is Null.
isNull :: Expr a -> Expr Bool
-- | The inverse of <a>isNull</a>, returns false if the expression supplied

notNull :: Expr a -> Expr Bool
-- | Takes a default value a and a nullable value. If the value is NULL,
-- the default value is returned, otherwise the value itself is returned.
-- Simliar to <tt>fromMaybe</tt>
fromNull :: Expr a -> Expr (Maybe a) -> Expr a
-- | Similar to fromNull, but takes a value argument rather than an Expr.
fromVal :: ShowConstant a => a -> Expr (Maybe a) -> Expr a
-- | Creates a constant expression from a haskell value.
constant :: ShowConstant a => a -> Expr a
-- | Turn constant data into a nullable expression. Same as <tt>constant .

param :: Expr a -> Expr a
-- | Create a named parameter with a default value.
namedParam :: Name -> Expr a -> Expr a
-- | Used to implement variable length arguments to <tt>func</tt>, below.
class Args a
-- | Can be used to define SQL functions which will appear in queries. Each
-- argument for the function is specified by its own Expr value. Examples
-- include:
--
-- <pre>
-- lower :: Expr a -> Expr (Maybe String)
-- lower str = func "lower" str
-- </pre>
--
-- The arguments to the function do not have to be Expr if they can be
-- converted to Expr:
--
-- <pre>
-- data DatePart = Day | Century deriving Show
-- </pre>
--
-- <pre>
-- datePart :: DatePart -> Expr (Maybe CalendarTime) -> Expr (Maybe Int)
-- datePart date col = func "date_part" (constant $ show date) col
-- </pre>
--
-- Aggregate functions can also be defined. For example:
--
-- <pre>
-- every :: Expr Bool -> ExprAggr Bool
-- every col = func "every" col
-- </pre>
--
-- Aggregates are implemented to always take one argument, so any attempt
-- to define an aggregate with any more or less arguments will result in
-- an error.
--
-- Note that type signatures are usually required for each function
-- defined, unless the arguments can be inferred.
