> Affects Versions: 0.7.0

> Hive doesn't allow you to use DB qualified column names in the WHERE or GROUP
> BY clauses. The workaround is to define a table alias:
> {noformat}
> hive> CREATE DATABASE db1;
> OK
> hive> CREATE TABLE db1.t(a INT, b INT);
> OK
> hive> SELECT * FROM db1.t WHERE db1.t.a > 100;
> FAILED: Error in semantic analysis: Line 1:26 Invalid table alias or column
> reference 'db1'
> hive> SELECT * FROM db1.t t WHERE t.a > 100;
> OK
> hive> SELECT * FROM db1.t GROUP BY db1.t.a;
> FAILED: Error in semantic analysis: Line 1:29 Invalid table alias or column
> reference 'db1'
> hive> SELECT * FROM db1.t t GROUP BY t.a;
> OK
> {noformat}
