Github user mebelousov commented on the issue: https://github.com/apache/zeppelin/pull/2442 @zjffdu @felixcheung Every day our users run about 1000 queries in the Greenplum (open source Postgres-based DB). There is great need for binding the query to the user and/or to the note. The precode `set application_name=#{noteId};` allows quickly find the note. This precode must be set by Zeppelin administrator, business users will not write any precode in each note for each jdbc-interpreter. I believe the precode in JDBC interpreter is necessary feature for entreprise users.
