Victoria Markman created DRILL-3396:
---------------------------------------
Summary: Add other function names to the error message disallowing
frame definition
Key: DRILL-3396
URL: https://issues.apache.org/jira/browse/DRILL-3396
Project: Apache Drill
Issue Type: Bug
Reporter: Victoria Markman
According to SQL Standard ( ISO/IEC 9075-2:2011(E) 6.10 <window function>)
window frame definition is not allowed.
page 220
7) If <ntile function>, <lead or lag function>, <rank function type> or
ROW_NUMBER is specified, then:
a) If <ntile function>, <lead or lag function>, RANK or DENSE_RANK is
specified, then the window ordering clause WOC of WDX shall be present.
{color:red}b) The window framing clause of WDX shall not be present.{color}
Calcite already throws an error, however it only mentions RANK and DENSE_RANK
functions even if your query does not contain them.
It is confusing and we should fix that for row_number and other functions as
well.

Error: PARSE ERROR: From line 1, column 54 to line 1, column 58: ROW/RANGE not
