The MariaDB blocking interface.

type error = int * string

The type of errors that can result from MariaDB API calls.

type 'a result = ('a, error) result

The result of MariaDB API calls.

module Time : sig ... end

Module representing MariaDB date- and time-related values.

module Field : sig ... end

This module defines a database field retrieved by a query.

module Row : sig ... end

A module representing database rows. Rows can be retrieved as different data structures, which as passed to the row retrieval functions from the Res module. There's built-in support for fetching rows as arrays and maps and hash tables of field name to field, but any module conforming to Row.S can be provided to those functions.

module Res : sig ... end

The module containing operations on MariaDB query results.

module Stmt : sig ... end

The module contains operations on MariaDB prepared statements.

type t

The type of database handles.

  ?pass:string ->
  ?db:string ->
  ?port:int ->
  ?socket:string ->
  ?flags:flag list ->
  ?options:client_option list ->
  unit ->
  t result

Connect to a MariaDB server at the specified location with the specified flags and optionally select a database db.

val close : t -> unit

Close a database handle.

val library_end : unit -> unit

library_end () should be called when you're done using the library. For maximum portability across MariaDB C client libraries, call this function only once, after you've closed all database handles.

val set_character_set : t -> string -> unit result

Sets the connection character set to the given parameter.

val select_db : t -> string -> unit result

select_db mariadb db changes the current database to db.

val change_user : t -> string -> string -> string option -> unit result

change_user mariadb user pass db changes the connection user to user with password password and optionally change to database db.

val set_client_option : t -> client_option -> unit

Sets the given client option on the connection.

val set_server_option : t -> server_option -> unit result

Sets the given server option on the connection.

val ping : t -> unit result

Checks if the connection to the MariaDB server is working. If the Reconnect option is set and the connection is down, a reconnect attempt will be made.

val autocommit : t -> bool -> unit result

Sets autocommit mode on or off.

val commit : t -> unit result

Commits the current transaction.

val rollback : t -> unit result

Rolls back the current transaction. Does not work if autocommit is enabled.

val prepare : t -> string -> Stmt.t result

prepare mariadb query creates a prepared statement for query. The query may contain ? as placeholders for parameters that can be bound by calling Stmt.execute.
