Konstantin updated CASSANDRA-15345:
-----------------------------------
Description:
The below example conditional update is wrongly evaluated to True and applied
even though clustering key 'k1' is not present in the table:
{{CREATE KEYSPACE test_keyspace WITH replication = \{'class': 'SimpleStrategy',
'replication_factor': 1};}}
{{CREATE TABLE test_table (id int, k text, version int static, v text, PRIMARY
KEY (id, k));}}
{{INSERT INTO test_table(id, version) VALUES (0, 0);}}
{{SELECT * FROM test_table;}}{{id | k | version | v}}
{{----+------+---------+------}}
{{ 0 | null | 0 | null}}{{(1 rows)}}
{{SELECT * FROM test_table WHERE id=0 AND k='k1';}}{{id | k | version | v}}
{{----+---+---------+---}}{{(0 rows)}}
{{UPDATE test_table SET v='foo', version=1 WHERE id=0 AND k='k1' IF version =
0;}}{{[applied]}}
{{-----------}}
{{ True}}{{SELECT * FROM test_table;}}{{id | k | version | v}}
{{----+----+---------+-----}}
{{ 0 | k1 | 1 | foo}}{{(1 rows)}}
{{DROP TABLE test_table;}}
{{DROP KEYSPACE test_keyspace;}}
