data RawSQL row

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

Instances

Eq row => Eq (RawSQL row)

Ord row => Ord (RawSQL row)

Show row => Show (RawSQL row)

IsString (RawSQL ())

Construct RawSQL () from String. The underlying ByteString will be encoded as UTF-8, so if you are working with a different encoding, you should not rely on this instance.

Monoid (RawSQL ())

(Show row, ToRow row) => IsSQL (RawSQL row)

rawSQL :: (Show row, ToRow row) => ByteString -> row -> RawSQL row

Construct RawSQL from ByteString and a tuple of parameters.

unRawSQL :: RawSQL () -> ByteString

Take query string out of RawSQL ().
