---------------------------------------------
Hi Jsmes,
I was on working on implementing power function. I have a basic functionality
implemented and have also written a simple test. While testing the simple
query "Select POWER(2.0,2.0)", it was unable to identify the power function(the
function i have implemented).
Error message : org.apache.phoenix.exception.PhoenixParserException: ERROR 605
(42P00): Syntax error. Unknown function: "POWER"
> Implement missing math built-in POWER function
