Language extension and write your query as a normal literal string. To most easily construct a query, enable GHC's OverloadedStrings The query andĮxecute functions require queries to be of type Query. Is not compatible with the Text API this makes it difficult toĬonstruct queries from fragments of strings. This library provides a Query type and a parameter substitutionįacility to address both ease of use and security. SQL injections is that many applications are sloppy in handling

The primary reason for widespread vulnerability to Susceptibility to attacks through the injection of maliciouslyĬrafted data. SQL-based applications are somewhat notorious for their nextRow :: FromRow r => Statement -> IO ( Maybe r).withBind :: ToRow params => Statement -> params -> IO a -> IO a.columnName :: Statement -> ColumnIndex -> IO Text.bind :: ToRow params => Statement -> params -> IO ().withStatement :: Connection -> Query -> ( Statement -> IO a) -> IO a.openStatement :: Connection -> Query -> IO Statement.execute_ :: Connection -> Query -> IO ().execute :: ToRow q => Connection -> Query -> q -> IO ().fold_ :: FromRow row => Connection -> Query -> a -> (a -> row -> IO a) -> IO a.fold :: ( FromRow row, ToRow params) => Connection -> Query -> params -> a -> (a -> row -> IO a) -> IO a.lastInsertRowId :: Connection -> IO Int64.query_ :: FromRow r => Connection -> Query -> IO.query :: ( ToRow q, FromRow r) => Connection -> Query -> q -> IO.setTrace :: Connection -> Maybe ( Text -> IO ()) -> IO ().withConnection :: String -> ( Connection -> IO a) -> IO a.newtype ColumnIndex = ColumnIndex ColumnIndex.public class DatabaseAdapter extends SQLiteOpenHelper Ĭursor cursor = database.query(DatabaseHelper.TABLE_NAME_2,ĬolumnArray, 'cat_id=' + ''' + w_id + '' AND nomi_id=' + '''+ nomi_id + ''', null, null, null, I have some trouble with the insert statement in the database, when im running the application the values have not been inserted.
