Dates were introduced in Hive 0.12.0 (HIVE-4055). |
Casting
Date types can only be converted to/from Date, Timestamp, or String types.
Valid casts to/from Date type | Result |
|---|---|
cast(date as date) | Same date value |
cast(timestamp as date) | The year/month/day of the timestamp is determined, based on the local timezone, and returned as a date value. |
cast(string as date) | If the string is in the form 'YYYY-MM-DD', then a date value corresponding to that year/month/day is returned. If the string value does not match this formate, then NULL is returned. |
cast(date as timestamp) | A timestamp value is generated corresponding to midnight of the year/month/day of the date value, based on the local timezone. |
cast(date as string) | The year/month/day represented by the Date is formatted as a string in the form 'YYYY-MM-DD'. |
