> Currently, when a window function is used without an OVER clause, Calcite reports a generic error message:
> "OVER clause is necessary for window functions"
> This message doesn't tell users which function is missing the OVER clause, which can be confusing when a query contains multiple window functions or when the error occurs in complex queries.
> Example query:
> SELECT rank(), row_number() OVER (ORDER BY id) FROM emp
> Current error message:
> "OVER clause is necessary for window functions"
> This change improves the error message to include the function name:
> "window function RANK requires an OVER clause"
> This makes it immediately clear which function needs to be fixed and it behaves consistently with PostgreSQL, improving the developer experience and reducing debugging time.
> Changes:
> - Added new resource message: absentOverClauseWithFunctionName
> - Updated SqlAggFunction and SqlValidatorImpl to use the new message format
> - Updated all related tests in SqlValidatorTest
