Open qwebug opened 5 months ago

qwebug commented 5 months ago

Describe:

SELECT \ FROM \

brings different results, when using CPU-only configurations and GPU-used configurations.

SQL with CPU-only Config:

CREATE TABLE t0(c0 DOUBLE);
INSERT INTO t0(c0) VALUES('Infinity');
ALTER SESSION SET EXECUTOR_DEVICE='CPU';
SELECT SUM(CAST(t0.c0 AS INT)) FROM t0;

Result:

EXPR$0
NULL

SQL with GPU-used Config:

ALTER SESSION SET EXECUTOR_DEVICE='GPU';
SELECT SUM(CAST(t0.c0 AS INT)) FROM t0;

Result:

EXPR$0
