Documentation

data DBConnection

Container type for any database connection Instances Show DBConnection

connect

:: MPool DBConnection Pool of connections -> StaticConfig -> IO (Int, DBConnection) (Index in the pool, connection) Connect to DB, get parameters from StaticConfig

connect'

:: String DB backend -> String DB connection path (format is backend-specific) -> IO DBConnection Connect to DB

commit :: DBConnection -> IO ()

Commit DB transaction

disconnect

:: ActionConfig -> Int Index of connection in the pool -> DBConnection -> IO () Free DB connection

disconnect' :: DBConnection -> IO ()

Disconnect from DB

query

:: DBConnection -> String SQL -> [SqlValue] List of SQL parameters -> IO [[SqlValue]] Generic query. Lazy.

query' :: DBConnection -> String -> [SqlValue] -> IO [[SqlValue]]

Generic query. Strict.

queryR :: DBConnection -> String -> [SqlValue] -> Model -> IO [Model]

Same as query, but return list of Model. Lazy.

queryR' :: DBConnection -> String -> [SqlValue] -> Model -> IO [Model]

Same as queryR, but strict.
