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.
