> 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}}.
