A method used to allow ignoring unset UPDATE clauses that can sometimes happen when the {{$setIfDefined}} operator is used.
A method used to allow ignoring unset UPDATE clauses that can sometimes happen when the {{$setIfDefined}} operator is used. To allow updating arbitrary records, phantom has a way to allow ignoring fields from being set in an update clause if they are of type scala.None.
A Future of Unit, as the result here cannot be known. If the update clause is invalid because the set part of the query is incomplete at the point where this method is invoked, the result is a successful future of Unit.
