Cassandra refuses a request with more than one equality relation to the
same column, for example
DELETE FROM tbl WHERE partitionKey = ? AND partitionKey = ?
It complains that
partitionkey cannot be restricted by more than one relation if it
includes an Equal
Currently, Scylla doesn't consider such requests an error. Whether or
not we should be compatible with Cassandra here is discussed in
issue #12472. But as long as we do accept this query, we should be
sure we do the right thing: "WHERE p = 1 AND p = 2" should match
nothing (not the first, or last, value being tested..), and "WHERE p = 1
AND p = 1" should match the matches of p = 1. This patch adds a test
for verify that these requests indeed yield correct results. The
test is scylla_only because, as explained above, Cassandra doesn't
support this feature at all.
