Maxim Gekk created SPARK-29371: ---------------------------------- Summary: Support interval field values with fractional parts Key: SPARK-29371 URL: https://issues.apache.org/jira/browse/SPARK-29371 Project: Spark Issue Type: Sub-task Components: SQL Affects Versions: 3.0.0 Reporter: Maxim Gekk
In PostgreSQL, field values can have fractional parts; for example '1.5 week' or '01:02:03.45'. Such input is converted to the appropriate number of months, days, and seconds for storage. When this would result in a fractional number of months or days, the fraction is added to the lower-order fields using the conversion factors 1 month = 30 days and 1 day = 24 hours. For example, '1.5 month' becomes 1 month and 15 days. Only seconds will ever be shown as fractional on output. See https://www.postgresql.org/docs/current/datatype-datetime.html#DATATYPE-INTERVAL-INPUT For example: {code} maxim=# SELECT INTERVAL '1.5 months' AS "One month 15 days"; One month 15 days ------------------- 1 mon 15 days (1 row) {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
