Anton Gozhiy closed DRILL-6834.
-------------------------------
Verified with Drill version 1.15.0-SNAPSHOT (commit
2dbd60984bef724e6ae1918fa4b31509ca7a986b)
Cases checked:
# With sqlline, all ddl queries with the option true and false.
# With sqlline, select cases with the option true and false.
# Queries with empty result
# Queries with error
# Large data sets, that requires multiple major fragments
# Used DBeaver to reproduce the original issue and to check the fix
> Introduce option to disable result set for DDL queries for JDBC connection

> Key: DRILL-6834
> URL: https://issues.apache.org/jira/browse/DRILL-6834
> Project: Apache Drill
> Issue Type: Improvement
> Reporter: Bohdan Kazydub
> Assignee: Bohdan Kazydub
> Priority: Major
> Labels: doc-complete, ready-to-commit
> Fix For: 1.15.0
>
>
> There are some tools (Unica, dBeaver, TalenD) that do not expect to obtain
> result set on CTAS query. As a result the query gets canceled. Hive, on the
> other hand, does not return result set for the query and these tools work
> well.
> To improve Drill's integration with such tools a session option
> {{`exec.return_result_set_for_ddl}}{{`}} is introduced. If the option is
> enabled (set to `true`) Drill's behaviour will be unchanged, i.e. a result
> set will be returned for all queries. If the option is disabled (set to
> `false`), CTAS, CREATE VIEW, CREATE FUNCTION, DROP TABLE, DROP VIEW, DROP
> FUNCTION, USE schema, SET option, REFRESH METADATA TABLE queries will not
> return result set but {{updateCount}} instead.
> The option affects JDBC connections only.
