Fix optimize_trivial_count_query with partition predicate
...
Consider the following example:
CREATE TABLE test(p DateTime, k int) ENGINE MergeTree PARTITION BY toDate(p) ORDER BY k;
INSERT INTO test VALUES ('2020-09-01 00:01:02', 1), ('2020-09-01 20:01:03', 2), ('2020-09-02 00:01:03', 3);
- SELECT count() FROM test WHERE toDate(p) >= '2020-09-01' AND p <= '2020-09-01 00:00:00'
In this case rpn will be (FUNCTION_IN_RANGE, FUNCTION_UNKNOWN (due to strict), FUNCTION_AND)
and for optimize_trivial_count_query we cannot use index if there is at least one FUNCTION_UNKNOWN.
since there is no post processing and return count() based on only the first predicate is wrong.
Before this patch FUNCTION_UNKNOWN was allowed for optimize_trivial_count_query, and the result was wrong.
And two examples above just to show the difference, the behaviour hadn't been changed with this patch:
- SELECT * FROM test WHERE toDate(p) >= '2020-09-01' AND p <= '2020-09-01 00:00:00'
In this case will be (FUNCTION_IN_RANGE, FUNCTION_IN_RANGE (due to non-strict), FUNCTION_AND)
so it will prune everything out and nothing will be read.
- SELECT * FROM test WHERE toDate(p) >= '2020-09-01' AND toUnixTimestamp(p)%5==0
In this case will be (FUNCTION_IN_RANGE, FUNCTION_UNKNOWN, FUNCTION_AND)
and all, two, partitions will be scanned, but due to filtering later none of rows will be matched.
