James Taylor updated PHOENIX-2223:
----------------------------------
    Issue Type: Improvement  (was: Bug)

> Support DELETE that strictly returns number of rows deleted
> -----------------------------------------------------------
>
>                 Key: PHOENIX-2223
>                 URL: https://issues.apache.org/jira/browse/PHOENIX-2223
>             Project: Phoenix
>          Issue Type: Improvement
>    Affects Versions: 4.3.0
>         Environment: CDH5
>            Reporter: James Heather
>
> If you create a table with no rows in, and then issue a delete statement with a {{where id=1}} clause, sqlline reports 1 row affected, even though no rows were actually deleted. It doesn't seem to happen without a {{where}} clause, or with something like {{where id<=2}}.
> Some experiments:
> {code}
> 0: jdbc:phoenix:172.xx.xx.xxx> create table names (id bigint(20) primary key, name varchar(20));
> No rows affected (1.158 seconds)
> 0: jdbc:phoenix:172.xx.xx.xxx> delete from names where id=1;
> 1 row affected (0.204 seconds)
> 0: jdbc:phoenix:172.xx.xx.xxx> 
> {code}
> and
> {code}
> 0: jdbc:phoenix:172.31.30.216> select * from names;
