Contents

Description

This module defines typed SQL.

Synopsis

Typed query statement

newtype Query p a Source #

Query type with place-holder parameter p and query result type a.

Constructors

Query 

Fields

Instances

Show (Query p a) Source #

Show query SQL string

Methods

showsPrec :: Int -> Query p a -> ShowS #

show :: Query p a -> String #

showList :: [Query p a] -> ShowS #

unsafeTypedQuery Source #

Arguments

:: String

Query SQL to type

-> Query p a

Typed result

Unsafely make typed Query from SQL string.

relationalQuery' :: Relation p r -> QuerySuffix -> Query p r Source #

From Relation into typed Query with suffix SQL words.

relationalQuery :: Relation p r -> Query p r Source #

From Relation into typed Query.

relationalQuerySQL :: Config -> Relation p r -> QuerySuffix -> String Source #

From Relation into untyped SQL query string.

Typed update statement

data KeyUpdate p a Source #

Update type with key type p and update record type a. Columns to update are record columns other than key columns, So place-holder parameter type is the same as record type a.

Constructors

KeyUpdate 

Fields

Instances

Show (KeyUpdate p a) Source #

Show update SQL string

Methods

showsPrec :: Int -> KeyUpdate p a -> ShowS #

show :: KeyUpdate p a -> String #

unsafeTypedKeyUpdate :: Pi a p -> String -> KeyUpdate p a Source #

Unsafely make typed KeyUpdate from SQL string.

typedKeyUpdate :: Table a -> Pi a p -> KeyUpdate p a Source #

Make typed KeyUpdate from Table and key columns selector Pi.

typedKeyUpdateTable :: TableDerivable r => Relation () r -> Pi r p -> KeyUpdate p r Source #

newtype Update p Source #

Update type with place-holder parameter p.

Constructors
