    Hello Renu, How are you executing the insert query, via some script or using vsql. Are you executing the "select count(*) from c" in a new session?

    hi Thanks for your response yes! am using script. yes! I am getting 0 rows when I execute the query in a new session!

    Hello Renu, By default the Autocommit is off in Vertica. Insert query will always need a "COMMIT" statement to save all the inserted records. If you don't specify a "COMMIT" in your script then the transaction ends without saving the changes. That might be the reason when you open a new session, you are getting 0 records. Hope this helps
