用Oracle打印100以内所有的质数的代码

Sure! Here is an example code snippet in Oracle SQL to print all prime numbers within 100:

DECLARE
    v_num NUMBER;
    v_is_prime BOOLEAN;
BEGIN
    FOR i IN 2..100 LOOP
        v_num := i;
        v_is_prime := TRUE;

        FOR j IN 2..FLOOR(SQRT(v_num)) LOOP
            IF MOD(v_num, j) = 0 THEN
                v_is_prime := FALSE;
                EXIT;
            END IF;
        END LOOP;

        IF v_is_prime THEN
            DBMS_OUTPUT.PUT_LINE(v_num);
        END IF;
    END LOOP;
END;
/

In this code, we use a nested loop to iterate through numbers from 2 to 100. For each number, we check if it is divisible by any number from 2 to its square root. If it is divisible, it is not a prime number and we set `v_is_prime` to FALSE. Otherwise, it is a prime number and `v_is_prime` remains TRUE. Finally, we use `DBMS_OUTPUT.PUT_LINE` to print the prime numbers.
