Jesus Camacho Rodriguez updated HIVE-24157: ------------------------------------------- Summary: Strict mode to fail on CAST timestamp <-> numeric (was: Strict mode to fail on CAST timestamp <-> numeral) > Strict mode to fail on CAST timestamp <-> numeric > ------------------------------------------------- > > Key: HIVE-24157 > URL: https://issues.apache.org/jira/browse/HIVE-24157 > Project: Hive > Issue Type: Improvement > Components: SQL > Reporter: Jesus Camacho Rodriguez > Priority: Major > > 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)
