Sorry. Here is the setup: CREATE TABLE test (id BIGSERIAL PRIMARY KEY, state1 INT NOT NULL, state2 INT NOT NULL, timestamp TIMESTAMP);
INSERT INTO test (state1, state2, timestamp) VALUES (1, 1, now() - interval '12 hours');
INSERT INTO test (state1, state2, timestamp) VALUES (1, 2, now() - interval '11 hours');
INSERT INTO test (state1, state2, timestamp) VALUES (1, 1, now() - interval '10 hours');
INSERT INTO test (state1, state2, timestamp) VALUES (2, 1, now() - interval '9 hours');
INSERT INTO test (state1, state2, timestamp) VALUES (1, 1, now() - interval '8 hours');
I want to write a query that spits out:
state1 | timestamp
--------+----------------------------
1 | now() - interval '12 hours'
2 | now() - interval '9 hours'
1 | now() - interval '8 hours'
Have a question what makes these values different other than the timestamp???
1, 1, now() - interval '12 hours'
1, 1, now() - interval '10 hours' The reason i ask, is because you show
1, 1, now() - interval '8 hours' in the desired output. What logic keeps the 8 hour and 12 hour but not the 10hour interval???
Its kinda hard to understand why the 10hour interval is being skipped???
