i using hdinsight , need delete clusters when finished running queries. however, need data gather survive day. working on queries create calculated columns table1 , insert them table2. first wanted simple test copy rows. can create external table select statement?

drop table if exists table2;  create external table table2 select *   table1 stored textfile location 'wasb://{container name}@{storage name}.blob.core.windows.net/';
