Summary: ADD TO_STRING AND LPAD functions
Key: PHOENIX-995
URL: https://issues.apache.org/jira/browse/PHOENIX-995
Project: Phoenix
Issue Type: New Feature
Reporter: Thomas D'Silva
Add TO_STRING(input number, base number) which can be used to convert a base 10
number to a number in any base between 2 to 62.
Add LPAD(input string, length int [, fill string]) which can be used to left
pad an input string.
Together these two functions can be used to generate IDs using sequences, for
example:
{code:sql}
CREATE SEQUENCE foo.bar START WITH 0 INCREMENT BY 62
SELECT LPAD(TO_STRING(NEXT VALUE FOR foo.bar,62), 10,'0') FROM SYSTEM."SEQUENCE"
{code}
