----------------------------------
Assignee: Shuxiong Ye
> Implement missing binary string built-in functions
> --------------------------------------------------
>
> Key: PHOENIX-1664
> URL: https://issues.apache.org/jira/browse/PHOENIX-1664
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Assignee: Shuxiong Ye
> Labels: Java, gsoc2015, mentor, sql
>
> Take a look at the typical binary string functions and bit string operators
> that are implemented in relational database systems
> (http://www.postgresql.org/docs/8.1/static/functions-binarystring.html and
> http://www.postgresql.org/docs/8.1/static/functions-bitstring.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 GET_BYTE, SET_BYTE, GET_BIT, SET_BIT,
> etc and missing operators include &, |, #, ~, <<, and >>. 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, as many of the
> existing built-in functions are already defined but are not applicable for
> binary types.
