To obtain a good analysis of a SQL statement especially in a new development environment, based on the environment that it is to be deployed on, it would good to sometime reflect/simulate the production volume.

Is there a way to input table cardinalities directly into the data dictionary so that the Optimizer could be made to act like in production.

I am aware that if this is was an environment with good cardinalities, these values could be exported and imported into another environment.

My question is this possible from scratch?
