Description

SQLParser can't parse table alias in brackets as following:

tpch> select c.*
> from (customer as c)
> ;
ERROR: syntax error at or near '('
LINE 2:5 from (customer as c)

Above case, I found error logs as follows.

Caused by: org.apache.tajo.engine.parser.SQLParseError: ERROR: syntax error at or near '('
LINE 2:5 from (customer as c)
