----------------------------------------
Summary: Window's ORDER BY expression is unparsed as positional
ordinal
Key: CALCITE-7644
URL: https://issues.apache.org/jira/browse/CALCITE-7644
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Sergey Nuyanzin
Assignee: Sergey Nuyanzin
Example sql
{code:sql}
SELECT "employee_id", "salary", "hire_date",
SUM("salary") OVER (
PARTITION BY "employee_id"
ORDER BY CASE WHEN "salary" > 1000 THEN 1 ELSE 0 END
RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS "sum_val"
FROM "employee"
{code}
{{OVER}} part will be unparsed as {{ OVER (PARTITION BY "employee_id" ORDER BY
4 RANGE ...)}}
while it should be
{{OVER (PARTITION BY "employee_id" ORDER BY CASE WHEN ... THEN 1 ELSE 0 END
RANGE ...)}}
it seems only occurs after {{ProjectToWindowRule}}.
