Sourceval create_pool : unit -> (Caqti_lwt.connection, Caqti_error.t) Caqti_lwt.Pool.t

Create a database connection pool. Raises Data_db_core.Exception.

Sourceval ctx_with_pool : unit -> Core.Ctx.t

Create a database connection pool and attach the pool to an empty context.

Sourceval add_pool : Core.Ctx.t -> Core.Ctx.t

Create a database connection pool and attach to provided context.

Sourceval query : Core.Ctx.t -> (Caqti_lwt.connection -> ('a, Caqti_error.t) Result.t Lwt.t) -> 'a Lwt.t

Run a database query.

The context has to contain a database connection or a database connection pool.

Sourceval with_connection : Core.Ctx.t -> (Core.Ctx.t -> 'a Lwt.t) -> 'a Lwt.t

Run a database query on a single connection. Can be used to set session variables that are bound to the same connection.

Sourceval atomic : Core.Ctx.t -> (Core.Ctx.t -> 'a Lwt.t) -> 'a Lwt.t

Run a database query atomically on a connection.

The context has to contain a database connection or a database connection pool. Fetch a database connection from context if necessary to make sure, that every query runs on the same connection.

Sourceval with_disabled_fk_check : Core.Ctx.t -> (Core.Ctx.t -> 'a Lwt.t) -> 'a Lwt.t
