Database.SQLite.Simple.ToRow

Description

The `ToRow` typeclass, for rendering a collection of parameters to a SQL query.

Predefined instances are provided for tuples containing up to ten elements.

Synopsis

- class GToRow f where
  - gtoRow :: f a -> [SQLData]
- class ToRow a where
  - toRow :: a -> [SQLData]

# Documentation

class GToRow f where #

Generic derivation of `ToRow`. For details about what can be derived refer to `GFromRow`.

Since: 0.4.18.1

Methods

gtoRow :: f a -> [SQLData] #

class ToRow a where #

A collection type that can be turned into a list of `SQLData` elements.

Since version 0.4.18.1 it is possible in some cases to derive a generic implementation for `ToRow`. Refer to the documentation for `FromRow` to see how this can be done.

Minimal complete definition

Nothing

Methods

toRow :: a -> [SQLData] #

`ToField` a collection of values.
