Jason Dere commented on HIVE-5192: ---------------------------------- There's actually some differences in what arguments are allowed by the two functions, so merging concat() and concat_ws() would mean the following changes in behavior for each function: concat() would allow lists of primitive types as arguments; each item of each list would be concatenated to the result string. concat_ws() would allow non-string types as arguments, so concat_ws('|', 1, 2) would be valid. > concat()/concat_ws() can use common implementation > -------------------------------------------------- > > Key: HIVE-5192 > URL: https://issues.apache.org/jira/browse/HIVE-5192 > Project: Hive > Issue Type: Improvement > Reporter: Jason Dere > > One of the review comments from HIVE-4844 mentioned that concat/concat_ws can > probably share a common implementation. -- This message is automatically generated by JIRA.
