[jira] [Created] (DRILL-4516) Transform SUM(1) query to COUNT(1)
Sudip Mukherjee created DRILL-4516: -- Summary: Transform SUM(1) query to COUNT(1) Key: DRILL-4516 URL: https://issues.apache.org/jira/browse/DRILL-4516 Project: Apache Drill Issue Type: Improvement Components: Query Planning & Optimization Reporter: Sudip Mukherjee If we connect drill with tableau we see some query requests like , select sum(1) tablename.
