Examples¶
master=> SELECT XOR(16, 24);
8
master=> SELECT XOR(101, 110);
11
master=> SELECT XOR(32, 64);
96
master=> SELECT XOR(512, 512);
0
master=> CREATE TABLE bit(b1 int, b2 int, b3 int);
executed
master=> INSERT INTO bit VALUES (1,2,3), (2, 4, 6), (4, 2, 6), (2, 8, 16), (null, null, 64), (5, 3, 1), (6, 1, 0);
executed
SELECT b1, b2, b3, xor(b1, b2), xor(b2, b3), xor(b1, b3) FROM bit;
