----------------------------------
Summary: The bug of timestampadd handles time
Key: CALCITE-2699
URL: https://issues.apache.org/jira/browse/CALCITE-2699
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.17.0, 1.18.0
Reporter: xuqianjin
Assignee: Julian Hyde
Two errors occur when {{timestampadd(MINUTE, 1, time '01:00:00')}} is executed:
# The return result can only be of {{TimeStamp}} type and is expected to be of
{{Time}} type
# The return value is {{1970-01-01 01:01:00}}, and the expectation is
{{01:01:00}}
# Compared with {{mysql}} database, I think it should meet the following
conditions:
||expression||Expect the result||
|timestampadd(MINUTE, -1, time '00:00:00')|NULL|
|timestampadd(MINUTE, 1, time '00:00:00')|00:01:00|
|timestampadd(MINUTE, 1, time '23:59:59')|00:00:59|
|timestampadd(SECOND, 1, time '23:59:59')|00:00:00|
|timestampadd(HOUR, 1, time '23:59:59')|00:59:59|
