Database.SQLite.Simple.Internal
Description
Internal bits. This interface is less stable and can change at any time. In particular this means that while the rest of the sqlite-simple package endeavors to follow the package versioning policy, this module does not. Also, at the moment there are things in here that aren't particularly internal and are exported elsewhere; these will eventually disappear from this module.
Synopsis
- newtype Connection = Connection {}
- data ColumnOutOfBounds = ColumnOutOfBounds {
- errorColumnIndex :: !Int
- data Field = Field {}
- newtype RowParseRO = RowParseRO {
- nColumns :: Int
- newtype RowParser a = RP {
- unRP :: ReaderT RowParseRO (StateT (Int, [SQLData]) Ok) a
- gettypename :: SQLData -> ByteString
Documentation
newtype Connection #
Connection to an open database.
You can use connectionHandle
to gain access to the underlying
http://hackage.haskell.org/package/direct-sqlite connection.
This may be useful if you need to access some direct-sqlite
functionality that's not exposed in the sqlite-simple API. This
should be a safe thing to do although mixing both APIs is
discouraged.
