Justin Bradford updated DRILL-4374:
-----------------------------------
Description:
Drill drops table references when rewriting this query, resulting in ambiguous
column references.
This query:
{code:sql} select s.uuid as site_uuid, psc.partner_id,
sum(psc.net_revenue_dollars) as revenue
from app.public.partner_site_clicks psc
join app.public.sites s on psc.site_id = s.id
join app.public.partner_click_days pcd on pcd.id = psc.partner_click_day_id
where s.generate_revenue_report is true and pcd.`day` = '2016-02-07'
group by s.uuid, psc.partner_id;
{code}
Results in this error:
{quote}
DATA_READ ERROR: The JDBC storage plugin failed while trying setup the SQL
query.
{quote}
Trying to run this re-written query:
{code:sql}
SELECT "site_uuid", "partner_id", SUM("net_revenue_dollars") AS "revenue" FROM
(SELECT "uuid" AS "site_uuid", "partner_id", "net_revenue_dollars" FROM
"public"."partner_site_clicks" INNER JOIN "public"."sites" ON
"partner_site_clicks"."site_id" = "sites"."id" INNER JOIN
"public"."partner_click_days" ON "partner_site_clicks"."partner_click_day_id" =
"partner_click_days"."id" WHERE "sites"."generate_revenue_report" IS TRUE AND
"partner_click_days"."day" = '2016-02-07') AS "t0" GROUP BY "site_uuid",
"partner_id"
{code}
That query fails due to an ambiguous "partner_id" reference as two of the
tables have that column.
