Database.PostgreSQL.PQTypes.SQL.Raw

Synopsis

data RawSQL row
rawSQL :: (Show row, ToRow row) => Text -> row -> RawSQL row
unRawSQL :: RawSQL () -> Text

Documentation

data RawSQL row Source #

Form of SQL query which is very close to libpqtypes specific representation. Note that, in particular, RawSQL () is isomorphic (modulo bottom) to Text.
