Documentation
query :: ( ToRow q, FromRow r, Unbox r) => Connection -> Query -> q -> IO ( Vector r) Source #
Perform a
SELECT
or other SQL query that is expected to return
results. All results are retrieved and converted before this
function returns.
query_ :: ( FromRow r, Unbox r) => Connection -> Query -> IO ( Vector r) Source #
A version of
query
that does not perform query substitution.
queryWith :: ( ToRow q, Unbox r) => RowParser r -> Connection -> Query -> q -> IO ( Vector r) Source #
A version of
query
taking parser as argument
queryWith_ :: Unbox r => RowParser r -> Connection -> Query -> IO ( Vector r) Source #
A version of
query_
taking parser as argument
