Describe:
SELECT <column> FROM <table> JOIN <table> brings different results, when using CPU-only configurations and GPU-used configurations.
SQL with CPU-only Config:
CREATE TABLE t0(c0 INT);
CREATE TABLE t1(c1 boolean);
INSERT INTO t1(c1) VALUES(FALSE), (TRUE), (FALSE);
INSERT INTO t0(c0) VALUES(-1), (2), (-3);
ALTER SESSION SET EXECUTOR_DEVICE='CPU';
SELECT t0.c0, t1.c1 FROM t1 JOIN t0 ON TRUE;
Result:
c0|c1
-1|false
2|false
-3|false
-1|true
2|true
-3|true
-1|false
2|false
-3|false
SQL with GPU-used Config:
ALTER SESSION SET EXECUTOR_DEVICE='GPU';
SELECT t0.c0, t1.c1 FROM t1 JOIN t0 ON TRUE;
Result:
c0|c1
-1|false
-1|true
-1|false
2|false
2|true
2|false
-3|false
-3|true
-3|false
