2010YOUY01 opened a new issue, #11275: URL: https://github.com/apache/datafusion/issues/11275
### Describe the bug There are two similar queries: `SELECT [expr1] FROM [tables] where [predicate]` `SELECT [expr2] FROM [tables] where [predicate]` The only difference is their projection expression, they should return the same number of row. The following queries return a different number of rows ### To Reproduce ``` CREATE TABLE t0 (v1 BOOLEAN); INSERT INTO t0 (v1) VALUES (false), (null); CREATE TABLE t1 (v1 BOOLEAN); INSERT INTO t1 (v1) VALUES (false), (null), (false); CREATE TABLE t2 (v1 BOOLEAN); INSERT INTO t2 (v1) VALUES (false), (true); ``` ``` > SELECT t2.v1, t1.v1 FROM t0, t1, t2 where t2.v1 IS DISTINCT FROM t0.v1; +-------+-------+ | v1 | v1 | +-------+-------+ | false | | | true | false | | true | | | true | false | | false | | | true | false | | true | | | true | false | +-------+-------+ 8 row(s) fetched. Elapsed 0.007 seconds. > SELECT * FROM t0, t1, t2 where t2.v1 IS DISTINCT FROM t0.v1; +-------+-------+-------+ | v1 | v1 | v1 | +-------+-------+-------+ | false | false | true | | false | | true | | false | false | true | | | false | false | | | | false | | | false | false | | | false | true | | | | true | | | false | true | +-------+-------+-------+ 9 row(s) fetched. Elapsed 0.006 seconds. ``` ### Expected behavior _No response_ ### Additional context Looks like this bug can be further minimized Found by SQLancer https://github.com/apache/datafusion/issues/11030 -- This is an automated message from the Apache Git Service.
