Hyunsik Choi commented on TAJO-1453:
------------------------------------
Regarding compatibility policy, Tajo should support at least features of
PostgreSQL for compatibility. What Tajo supports SQL features beyond PostgreSQL
would be nice in my opinion.
I'm not sure what a single table with parentheses means. But, PostgreSQL also
supports explicit join order. Please refer to
http://www.postgresql.org/docs/8.2/static/explicit-joins.html.
> sql parse error occured with join query
> ---------------------------------------
>
> Key: TAJO-1453
> URL: https://issues.apache.org/jira/browse/TAJO-1453
> Project: Tajo
> Issue Type: Bug
> Components: parser
> Affects Versions: 0.10.0
> Reporter: Jungryong Lee
> Priority: Minor
>
> It is simple parse error.
> I am testing Tajo with BI solution, Birst.
> Birst usually generate join query like following:
> select table1.* from table1 inner join (table2) on (table1.id = table2.id);
> If "table2" has parenthesis, Tajo displays follwing error:
> ERROR: syntax error at or near 'table2'
> I didn't check ANSI SQL doesn't allow parenthesis in this case.
> But Almost databases I evaluated support this case.
