Can't use DB qualified column names in WHERE or GROUP BY clauses
----------------------------------------------------------------
Key: HIVE-2228
URL: https://issues.apache.org/jira/browse/HIVE-2228
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.7.0
Reporter: Carl Steinbach
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}
