Instances

MonadTrans SqliteReader

Monad m => Monad (SqliteReader m)

Functor m => Functor (SqliteReader m)

Applicative m => Applicative (SqliteReader m)

MonadCatchIO m => MonadCatchIO (SqliteReader m)

runSqlite :: MonadCatchIO m => SqliteReader m a -> Pool Connection -> m a

Run a series of database actions within a single transactions. On any exception, the transaction is rolled back.

runSqliteConn :: MonadCatchIO m => SqliteReader m a -> Connection -> m a

Run a series of database actions within a single transactions. On any exception, the transaction is rolled back. You probably want to take advantage of connection pooling by using runSqlite instead

withSqlite

Arguments

:: MonadCatchIO m

=> String

-> (Pool Connection -> m a)

-> m a

Handles opening and closing of the database connection automatically.

withSqliteConn :: MonadCatchIO m => String -> (Connection -> m a) -> m a

Handles opening and closing of the database connection automatically. You probably want to take advantage of connection pooling by using withSqlite instead
