xinyiZzz opened a new issue #5859: URL: https://github.com/apache/incubator-doris/issues/5859
**Describe the bug** query 1: ``` SELECT * FROM tab1 INNER JOIN tab0 ON NULL = NULL ``` `NULL = NULL` in Mysql is `false` `NULL = NULL` in Doris is `true` In contrast, query 2: ``` SELECT * FROM tab1 where NULL = NULL ``` NULL = NULL is `false` in both Doris and Mysql In addition, the conclusion is the same in NULL NOT BETWEEN NULL AND (NULL ), NULL <> NULL, NULL <= NULL. Found through the sqllogictest test case. -- This is an automated message from the Apache Git Service.
