Description

Synopsis

postgresqlConnect :: MonadIO m => [(String, String)] -> (Database -> m a) -> m a data DriverInterface = DriverInterface { connect :: forall m a. MonadIO m => [(String, String)] -> (Database -> m a) -> m a requiredOptions :: [(String, String)] } driver :: DriverInterface

Documentation

postgresqlConnect :: MonadIO m => [(String, String)] -> (Database -> m a) -> m a Source

data DriverInterface Source

Interface which drivers should implement. The connect function takes some driver specific name, value pairs use to setup the database connection, and a database action to run. requiredOptions lists all required options with a short description, that is printed as help in the DBDirect program. Constructors DriverInterface connect :: forall m a. MonadIO m => [(String, String)] -> (Database -> m a) -> m a requiredOptions :: [(String, String)]

driver :: DriverInterface Source

This driver passes its options through to HDBC. HDBC refers to http://www.postgresql.org/docs/8.1/static/libpq.html#LIBPQ-CONNECT for the meaning of the options.
