Gengliang Wang updated SPARK-34881: ----------------------------------- Parent: SPARK-35161 Issue Type: Sub-task (was: New Feature) > New SQL Function: TRY_CAST > -------------------------- > > Key: SPARK-34881 > URL: https://issues.apache.org/jira/browse/SPARK-34881 > Project: Spark > Issue Type: Sub-task > Components: SQL > Affects Versions: 3.2.0 > Reporter: Gengliang Wang > Assignee: Gengliang Wang > Priority: Major > Fix For: 3.2.0 > > > Add a new SQL function try_cast. try_cast is identical to CAST with > `spark.sql.ansi.enabled` as true, except it returns NULL instead of raising > an error. This expression has one major difference from `cast` with > `spark.sql.ansi.enabled` as true: when the source value can't be stored in > the target integral(Byte/Short/Int/Long) type, `try_cast` returns null > instead of returning the low order bytes of the source value. > This is learned from Google BigQuery and Snowflake: > https://docs.snowflake.com/en/sql-reference/functions/try_cast.html > https://cloud.google.com/bigquery/docs/reference/standard-sql/functions-and-operators#safe_casting -- 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
