Subject Re: where clause on Phoenix view built on Hbase table throws error
Date Wed, 05 Oct 2016 14:34:15 GMT
Thanks John.

0: jdbc:phoenix:rhes564:2181> select "Date","volume" from "tsco" where
"Date" = '1-Apr-08';
+-----------+-----------+
|   Date    |  volume   |
+-----------+-----------+
| 1-Apr-08  | 49664486  |
+-----------+-----------+
1 row selected (0.016 seconds)

BTW I believe double quotes in enclosing phoenix column names are needed
for case sensitivity on Hbase?


Also does Phoenix have type conversion from VARCHAR to integer etc? Is
there such document

Regards
