Project: DELETE and SELECT MULT operations

5 Dezembro 2020, 22:58 António Manuel Raminhos Cordeiro Grilo

Since the server cannot decrypt the result of comparison operations, the DELETE command cannot be implemented as described in the guide. Instead, it will be replaced by two simple operations:

- SELECT LINE linenum FROM tablename
- DELETE linenum FROM tablename

As to the SELECT MULT operation, you don't need to implement it. The main reason is that the large number of multiplications causes the noise budget to decrease too fast. Anyway, it is structurally very similar to the SELECT SUM operation, so the implementation difficulty would be the same.
