问题
I am trying to use Apache Drill to export a .csv file. This other question indicated that this is achieved by:
use dfs.tmp;
alter session set `store.format`='csv';
create table dfs.tmp.my_output as select * from cp.`employee.json`;
I tried running this block (of three commands) simultaneously in the Apache Drill web interface but got the error bellow. It somehow is not recognizing the ; or not taking multiple commands.
I also tried running each line separately, without the ; but the changes of the two commands did not persist (and the export command (3rd command) deafauted back to exporting a parquet file (the set default)).
How can I run this in Drill?

Drill Web-UI does not support submitting multiple queries within the same query page. Please try using SqlLine or submit in Web-UI one-by-one
alter system set `store.format`='csv';
query to set store.format at the system level, since Web-UI does not store session by default and after that submit the following query
create table dfs.tmp.my_output as select * from cp.`employee.json`;
