molecule.sql.core.query.cursorStrategy.PrimaryUnique
case class PrimaryUnique[Tpl](elements: List[Element], optLimit: Option[Int], cursor: String, m2q: Model2SqlQuery[Tpl] & SqlQueryBase) extends SqlQueryResolve[Tpl], FutureUtils, Pagination[Tpl], ModelTransformations_, MoleculeLogging

Molecule has a unique attribute that is sorted first.

Then we can easily filter by its previous value in either direction.

Type parameters

Tpl

Type of each row

Value parameters

cursor

Base64 encoded cursor meta information

elements

Molecule model

optLimit

When going forward from start, use a positive number. And vice versa from end with a negative number. Can't be zero.
