[jira] [Updated] (CALCITE-5447) Add DATE_TRUNC for BigQuery
[ https://issues.apache.org/jira/browse/CALCITE-5447?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oliver Lee updated CALCITE-5447:
--------------------------------
Description:
Adding in BigQuery's definition of DATE_TRUNC as described [https://g3doc.corp.google.com/company/teams/googlesql/reference/date_functions.md?cl=head#date-trunc]
ex.
DATE_TRUNC('2022-01-05', month) -> 2022-01-01
DATE_TRUNC('2022-01-05', day) -> 2022-01-05
DATE_TRUNC('2022-01-05', year) -> 2022-01-01
Note: BigQuery says it'll support
* {{DAY}}
* {{WEEK}}
* {{{}WEEK(WEEKDAY){}}}following: {{{}SUNDAY{}}}, {{{}MONDAY{}}}, {{{}TUESDAY{}}}, {{{}WEDNESDAY{}}}, {{{}THURSDAY{}}}, {{{}FRIDAY{}}}, or {{{}SATURDAY{}}}.
* {{ISOWEEK}}
* {{MONTH}}
* {{QUARTER}}
* {{YEAR}}
* {{ISOYEAR}}
but as of right now this ticket will only support
* {{DAY}}
* {{WEEK}}
* {{MONTH}}
* {{QUARTER}}
* {{{}{}}}{{{}YEAR{}}}
ISOWEEK, ISOYEAR is blocked by https://issues.apache.org/jira/browse/CALCITE-5369
and WEEK(WEEKDAY) will have a follow up PR as well{{{}{}}}
