Summary: Strict mode to fail on CAST timestamp <-> numeral Key: HIVE-24157 URL: https://issues.apache.org/jira/browse/HIVE-24157 Project: Hive Issue Type: Improvement Components: SQL Reporter: Jesus Camacho Rodriguez There is some interest in enforcing that CAST numeral <-> timestamp is disallowed to avoid confusion among users, e.g., SQL standard does not allow numeral <-> timestamp casting, timestamp type is timezone agnostic, etc. We should introduce a strict config for timestamp (similar to others before): If the config is true, we shall fail while compiling the query with a meaningful message. To provide similar behavior, Hive has multiple functions that provide clearer semantics for numeral to timestamp conversion (and vice versa): https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-DateFunctions -- This message was sent by Atlassian Jira (v8.3.4#803005)
