[jira] [Updated] (HIVE-4032) Inserting data into Hive table from a
query, when the query is a partitioned table and select * ,will generate a
SemanticException
[ https://issues.apache.org/jira/browse/HIVE-4032?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
caofangkun updated HIVE-4032:
-----------------------------
Description:
Inserting data into Hive table from a query , when the query is : select * from a_partitioned_table, will throw a SemanticException .
It seems that "*" contains the virtual partition columns.
drop table if exists zr_test;
create table if not exists zr_test (key string, value string) partitioned by (dt string);
drop table if exists zr_test_1;
create table if not exists zr_test_1 (key string, value string) partitioned by (dt string);
--Query One
explain
insert into table zr_test partition (dt='20130217') select key, value from zr_test_1 where dt='20130217';
--Query Two
explain
insert into table zr_test partition (dt='20130217') select * from zr_test_1 where dt='20130217';
Ouery One works well, bug Query Two failed with the following information:
FAILED: SemanticException [Error 10044]: Line 2:18 Cannot insert into target table because column number/types are different ''20130217'': Table insclause-0 has 2 columns, but query has 3 columns.
