Module `IBase.ResultsDatabase`

val schema_hum : string: some human-readable string describing the tables

val create_tables : ?⁠prefix:string -> Sqlite3.db -> unit
val get_database : unit -> Sqlite3.db: The results database. You should always use this function to access the database, as the connection to it may change during the execution (see new_database_connection).

val new_database_connection : unit -> unit: Closes the previous connection to the database (if any), and opens a new one. Needed after calls to fork(2).

val db_close : unit -> unit: close the current connection to the database

val create_db : unit -> unit: create the database file and initialize all the necessary tables

type registered_stmt

val register_statement : ('a, unit, string, registered_stmt) Base.format4 -> 'a

Return a function unit -> Sqlite3.stmt that can be called (once the DB has been initialized) to get the prepared statement corresponding to the current DB connection. Use this to prepare statements only once per DB connection.

In particular, clients of this need not worry about calling Sqlite3.finalize on the returned statement, or about generating new statements when the connection to the DB changes: this is all handled internally.

val with_registered_statement : registered_stmt -> f:(Sqlite3.db -> Sqlite3.stmt -> 'a) -> 'a
