Zheng Shao commented on HIVE-855: --------------------------------- @HIVE-855.1.patch: {code} - value = "_FUNC_(str1, str2) - returns the concatenation of str1 and str2", + value = "_FUNC_(str1, str2, ... strN) - returns the concatenation of str1 and str2", {code} Minor issue, the comment should say "returns the concatenation of str1, str2, ... strN". By the way, I forget to tell you that we need to do two more things: 1. Add "describe" and "describe extended" to the udf_concat.q file. Take a look at "trunk/ql/src/test/queries/clientpositive/udf_hour_minute_second.q" for example. 2. Overwrite the test that contains "show functions" - it might be changed whenever we are editing UDFs. Please upload the new patch as HIVE-855.2.patch. > UDF: Concat should accept multiple arguments > -------------------------------------------- > > Key: HIVE-855 > URL: https://issues.apache.org/jira/browse/HIVE-855 > Project: Hadoop Hive > Issue Type: Improvement > Components: Query Processor > Affects Versions: 0.5.0 > Reporter: Zheng Shao > Assignee: Paul Yang > Attachments: HIVE-855.1.patch > > > According to mysql, concat should accept multiple arguments. > http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_concat -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
