Summary: Support static and partition dynamic in insert
into/overwrite DML
Key: CARBONDATA-1595
URL: https://issues.apache.org/jira/browse/CARBONDATA-1595
Project: CarbonData
Issue Type: Sub-task
Components: sql
Affects Versions: 1.2.0
Reporter: wyp
In [CARBONDATA-910|https://issues.apache.org/jira/browse/CARBONDATA-910]
carbondata implement partition feature, it's very useful. But if we want add
partition data in carbondata table,we must be use {{ alter}} syntax as
following:
{code}
carbon.sql("ALTER TABLE temp.test_table ADD PARTITION('2017-10-18',
'2017-10-19')")
{code}
If you have many partitions that should be add to some table, you should run
the sql many times, It's boring and inefficiency. So it;s very useful to
support static and partition dynamic in insert into/overwrite DML:
{code}
Static partition:
INSERT OVERWRITE TABLE tablename1 [PARTITION (partcol1=val1) [IF NOT EXISTS]]
select_statement1 FROM from_statement;
INSERT INTO TABLE tablename1 [PARTITION (partcol1=val1)] select_statement1 FROM
from_statement;
Dynamic partition:
INSERT OVERWRITE TABLE tablename1 [PARTITION (partcol1) [IF NOT EXISTS]]
select_statement1 FROM from_statement;
INSERT INTO TABLE tablename1 [PARTITION (partcol1)] select_statement1 FROM
from_statement;
{code}
