unit ->

Create a database connection pool. Raises Data_db_core.Exception
.
val ctx_with_pool : unit -> Core.Ctx.t
Create a database connection pool and attach the pool to an empty context.
val add_pool : Core.Ctx.t -> Core.Ctx.t
Create a database connection pool and attach to provided context.
val query :
Core.Ctx.t ->
(Caqti_lwt.connection -> ('a, Caqti_error.t) Stdlib.Result.t Lwt.t) ->
'a Lwt.t
Run a database query.
The context has to contain a database connection or a database connection pool.
val 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.
val 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.
val with_disabled_fk_check : Core.Ctx.t -> (Core.Ctx.t -> 'a Lwt.t) -> 'a Lwt.t
Disables foreign key checks if supported by the database.
