Query is:exact
A query string. This type is intended to make it difficult to
construct a SQL query by concatenating string fragments, as that is an
extremely common way to accidentally introduce SQL injection
vulnerabilities into an application.
This type is an instance of
IsString, so the easiest way to
construct a query is to enable the
OverloadedStrings language
extension and then simply write the query in double quotes.
{-# LANGUAGE OverloadedStrings #-}
import Database.PostgreSQL.Simple
q :: Query
q = "select ?"
The underlying type is a
ByteString, and literal Haskell
strings that contain Unicode characters will be correctly transformed
to UTF-8.

A query is a function that maps points in a vector space to values in
some monoid. Queries naturally form a monoid, with two queries being
combined pointwise.

The idea for annotating diagrams with monoidal queries came from the
graphics-drawingcombinators package,

A
Query can be thought of as a declaration of interest in some
set of data. A
QueryResult is the set of data associated with
that interest set. The
crop function provides a way to
determine what part of a given
QueryResult is relevant to a
given
Query.

The Query module defines a type for "queries" on diagrams,
which are functions from points in a vector space to some monoid.
