Subject [jira] [Created] (PHOENIX-1663) Implement missing string built-in functions
Date Sat, 14 Feb 2015 06:20:13 GMT
James Taylor created PHOENIX-1663:
-------------------------------------

             Summary: Implement missing string built-in functions
                 Key: PHOENIX-1663
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1663
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor


Take a look at the typical math functions that are implemented in relational database systems
(http://www.postgresql.org/docs/current/static/functions-math.html) and implement the same
for Phoenix in Java following this guide: http://phoenix-hbase.blogspot.com/2013/04/how-to-add-your-own-built-in-function.html

Examples of missing functions include POWER, LOG, EXP, SQRT, CBRT, etc. As a guide, examine
how ROUND is implemented in Phoenix as an abstract function with concrete functions per type:
long, decimal, and date/time types.
