Class type

SQL literal values.

type 'a t = ..

The type of literals. Can be extended by drivers.

type t +=

| Bool : bool -> bool t
| Int : int -> int t
| Float : float -> float t
| String : string -> string t
| Blob : bytes -> bytes t
(*
Basic SQL literals.
*)

Literal creation

The functions below create literal values of the appropriate types.

val bool : bool -> bool t

val int : int -> int t

val float : float -> float t

val string : string -> string t

val blob : bytes -> bytes t

module Null : sig ... end

Literals for nullable fields.

type ('a, 'b) lit = 'b t

module Vector : Sequoia_vector.S with type ('a, 'b) elem := ('a, 'b) lit

Vectors of SQL literals.

Functions useful for driver writers

val build : 
  placeholder:(int -> string) ->
  Sequoia_common.build_step ->
  'a t ->
  Sequoia_common.build_step

Build a literal value.

val to_param : 'a t -> Sequoia_param.t

Convert a literal value to a query parameter.
