gatorsmile commented on issue #26995: [SPARK-30341][SQL] Overflow check for interval arithmetic operations URL: https://github.com/apache/spark/pull/26995#issuecomment-577949404 When ANSI is on, interval add/subtract/negative/multiply/divide will overflow if any field overflows. However, when ANSI is off and overflow happens, why multiply/divide will throw an exception but add/subtract/negative will not throw an exception? This looks inconsistent.
