  1. unSqlReadBackend :: SqlReadBackend -> SqlBackend

    esqueleto Database.Esqueleto.Experimental

    No documentation available.

  2. class (PersistCore backend, PersistStoreRead backend) => PersistQueryRead backend

    esqueleto Database.Esqueleto.Legacy

    Backends supporting conditional read operations.

  3. class (Show BackendKey backend, Read BackendKey backend, Eq BackendKey backend, Ord BackendKey backend, PersistCore backend, PersistField BackendKey backend, ToJSON BackendKey backend, FromJSON BackendKey backend) => PersistStoreRead backend

    esqueleto Database.Esqueleto.Legacy

    No documentation available.

  4. class PersistStoreRead backend => PersistUniqueRead backend

    esqueleto Database.Esqueleto.Legacy

    Queries against Unique keys (other than the id Key). Please read the general Persistent documentation to learn how to create Unique keys. Using this with an Entity without a Unique key leads to undefined behavior. A few of these functions require a single Unique, so using an Entity with multiple Uniques is also undefined. In these cases persistent's goal is to throw an exception as soon as possible, but persistent is still transitioning to that. SQL backends automatically create uniqueness constraints, but for MongoDB you must manually place a unique index on a field to have a uniqueness constraint.

  5. RepeatableRead :: IsolationLevel

    esqueleto Database.Esqueleto.Legacy

    No documentation available.

  6. type SqlBackendCanRead backend = (BackendCompatible SqlBackend backend, PersistQueryRead backend, PersistStoreRead backend, PersistUniqueRead backend)

    esqueleto Database.Esqueleto.Legacy

    A constraint synonym which witnesses that a backend is SQL and can run read queries.

  7. newtype SqlReadBackend

    esqueleto Database.Esqueleto.Legacy

    An SQL backend which can only handle read queries The constructor was exposed in 2.10.0.

  8. SqlReadBackend :: SqlBackend -> SqlReadBackend

    esqueleto Database.Esqueleto.Legacy

    No documentation available.

  9. type SqlReadT (m :: Type -> Type) a = forall backend . SqlBackendCanRead backend => ReaderT backend m a

    esqueleto Database.Esqueleto.Legacy

    Like SqlPersistT but compatible with any SQL backend which can handle read queries.

  10. StatementAlreadyFinalized :: Text -> PersistentSqlException

    esqueleto Database.Esqueleto.Legacy

    No documentation available.
