-----------------------------------
Summary: CTAS with 0 records from a SELECT query should create the
table with metadata
Key: DRILL-5298
URL: https://issues.apache.org/jira/browse/DRILL-5298
Project: Apache Drill
Issue Type: Bug
Components: Metadata, Query Planning & Optimization
Affects Versions: 1.9.0
Environment: MapR 5.2
Reporter: Senthilkumar
Fix For: 1.9.0
Hello team,
I create a table in Drill using CTAS as
CREATE TABLE CTAS_TEST AS SELECT * FROM `hive.default`.`test` WHERE 1 = 0
It runs successfully.
But the table is not getting created as there are 0 records getting returned
from the SELECT query.
CTAS should still go ahead and create the table with the column metadata.
When BI tools fire up multi-pass queries, with CTAS in the first query, the
subsequent queries fail because of a missing table.
In databases like SQL Server, Postgres, CTAS will create the table, even if the
SELECT doesnt return any rows.
