Tanner Clary created CALCITE-5469: ------------------------------------- Summary: Implement BigQuery DATETIME_ADD/DATETIME_DIFF Key: CALCITE-5469 URL: https://issues.apache.org/jira/browse/CALCITE-5469 Project: Calcite Issue Type: Sub-task Reporter: Tanner Clary Assignee: Tanner Clary
Add support for BigQuery's {{DATETIME_ADD/DATETIME_DIFF}} functions. {{DATETIME_ADD(datetime, interval)}} can accept a timestamp (or a datetime, which is an alias for timestamp) for its first argument and an interval for its second. The output is the datetime that occurs {{interval}} after the provided {{datetime}}. {{DATETIME_DIFF(datetime, datetime2, timeUnit)}} returns the whole number of {{timeUnit}} between {{datetime}} and {{datetime2}}, with the result being negative if {{datetime}} occurs before {{datetime2}} Examples: {{DATETIME_ADD(TIMESTAMP '2008-12-25 15:30:00', INTERVAL 5 MINUTE)}} would return: '2008-12-25 15:35:00'. {{DATETIME_DIFF(DATETIME '2008-12-25 15:30:00', DATETIME '2008-12-26 15:30:00', DAY)}} would return: -1. -- This message was sent by Atlassian Jira (v8.20.10#820010)
