Description

Top-level Beam module. This module re-exports all the symbols necessary for most common user operations.

The most interesting modules are Database.Beam.Schema and Database.Beam.Query.

This is mainly reference documentation. Most users will want to consult the manual.

The API has mostly stayed the same, but not all the examples given there compile.

module Database.Beam.Query

module Database.Beam.Schema

class (BeamBackend be, Monad m, MonadIO m, Sql92SanityCheck syntax) => MonadBeam syntax be handle m | m -> syntax be handle where Source #

A class that ties together a Sql syntax, backend, handle, and monad type.

Intuitively, this allows you to write code that performs database commands without having to know the underlying API. As long as you have an appropriate handle from a database library that Beam can use, you can use the MonadBeam methods to execute the query.

Provided here is a low-level interface. Most often, you'll only need the withDatabase and withDatabaseDebug function. The 'run*' functions are wrapped by the appropriate functions in Database.Beam.Query.

This interface is very high-level and isn't meant to expose the full power of the underlying database. Namely, it only supports simple data retrieval strategies. More complicated strategies (for example, Postgres's COPY) are supported in individual backends. See the documentation of those backends for more details.

Re-exports

class Monad m => MonadIO (m :: * -> *) where #

Monads in which IO computations may be embedded. Any monad built by applying a sequence of monad transformers to the IO monad will be an instance of this class.

Instances should satisfy the following laws, which state that liftIO is a transformer of monads:

```
liftIO . return = return
```

liftIO (m >>= f) = liftIO m >>= (liftIO . f)
