我可以按 TypeORM/PostgreSQL 中的加密列对结果进行排序吗？

Question

I'm coding with NestJS using TypeORM and PostgreSQL database. I created an entity with a transformer in order to store encrypted data. Am I able to somehow sort the results by the encrypted column on database side?

Let's say I have an encrypted name column. repository.find({ order: { name: 'ASC' } }) doesn't sort the results by name. I suppose that the results are sorted by encrypted name.

Answer 1

That is fundamentally impossible. To sort, you need to know the clear text, which the database doesn't.

Security has a negative impact on usability and performance, that is unavoidable.
