Parameters

module R : RAW_DRIVER_FULL

Signature

type connection = R.connection

type error = R.error

val dialect : Driver.dialect

val error_message : error -> string

val connect : string -> (connection, error) result

val close : connection -> unit

val with_connection : 
  string ->
  (connection -> ('a, error) result) ->
  ('a, error) result

val exec : 
  connection ->
  string ->
  params:Driver.Value.t array ->
  (unit, error) result

val exec_result : 
  connection ->
  string ->
  params:Driver.Value.t array ->
  (Driver.command_result, error) result

Like exec but reports the affected-row count and any generated id.

val query : 
  connection ->
  string ->
  params:Driver.Value.t array ->
  (Driver.row list, error) result

val query_one : 
  connection ->
  string ->
  params:Driver.Value.t array ->
  (Driver.row option, error) result

val query_fold : 
  connection ->
  string ->
  params:Driver.Value.t array ->
  init:'acc ->
  f:('acc -> Driver.row -> 'acc) ->
  ('acc, error) result

val query_iter : 
  connection ->
  string ->
  params:Driver.Value.t array ->
  f:(Driver.row -> unit) ->
  (unit, error) result

val transaction : 
  connection ->
  (connection -> ('a, error) result) ->
  ('a, error) result

val begin_transaction : connection -> (unit, error) result

Start a transaction using the backend's native mechanism.

Drivers must not route transaction control through the prepared-statement path: MySQL 8 rejects a prepared BEGIN with error 1295.

val commit : connection -> (unit, error) result

val rollback : connection -> (unit, error) result

val placeholder : int -> string

val returning_supported : bool

val upsert_syntax : [ `PostgreSQL | `SQLite | `Standard ]

val last_insert_id : connection -> (int64, error) result

val ddl_capabilities : Driver.ddl_capabilities
