Subject [jira] [Commented] (PHOENIX-1663) Implement missing string built-in functions
Date Sun, 08 Mar 2015 06:23:38 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-1663?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14351937#comment-14351937

James Taylor commented on PHOENIX-1663:
---------------------------------------

[~naveenmadhire] - please create a subtask JIRA from this one for the specific string built-in
function you'd like to implement. This JIRA is a grouping JIRA for *all* unimplemented string
functions. How about the INSTR function from Oracle (SQL server calls it CHARINDEX  and Postgres
calls it POSITION) ? Once you create that, I'll assign it to you.

> Take a look at the typical string functions that are implemented in relational database
systems (http://www.postgresql.org/docs/8.1/static/functions-string.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 POSITION, OVERLAY, REPEAT, etc.
