             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.
