`@Formula()` decorator can be used to map some SQL snippet to your entity. The SQL fragment can be as complex as you want and even include subselects. ```typescript @formula('obj_length * obj_height * obj_width') objectVolume?: number; ``` Formulas will be added to the select clause automatically. In case you are facing problems with `NonUniqueFieldNameException`, you can define the formula as a callback that will receive the entity alias in the parameter: ```typescript @formula(alias => `${alias}.obj_length * ${alias}.obj_height * ${alias}.obj_width`) objectVolume?: number; ```
