[jira] [Created] (DRILL-8013) Drill attempts to push "$SUM0" to JDBC storage plugin for AVG

James Turton created DRILL-8013:
-----------------------------------

             Summary: Drill attempts to push "$SUM0" to JDBC storage plugin for AVG
                 Key: DRILL-8013
                 URL: https://issues.apache.org/jira/browse/DRILL-8013
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - JDBC
    Affects Versions: 1.19.0
            Reporter: James Turton
             Fix For: 1.20.0


When running a query that includes the AVG aggregate against a JDBC data source, Drill transforms AVG into SUM0 / COUNT.  COUNT is pushed down to the source correctly but SUM0 is pushed down as "$SUM0" instead of SUM, causing a syntax error.  More info is visible at the link below.
