-------------------------------------
Summary: Add 2-argument support for PERCENTILE_CONT/DISC
Key: CALCITE-5564
URL: https://issues.apache.org/jira/browse/CALCITE-5564
Project: Calcite
Issue Type: Improvement
Reporter: Tanner Clary
Assignee: Tanner Clary
Calcite currently has implementations for the {{PERCENTILE_CONT}} and
{{PERCENTILE_DISC}} functions. Their syntax may be found
[here|https://learn.microsoft.com/en-us/sql/t-sql/functions/percentile-cont-transact-sql?view=sql-server-ver16].
BigQuery offers these functions as well, but the syntax is slightly different,
and may be found
[here|https://cloud.google.com/bigquery/docs/reference/standard-sql/functions-and-operators#percentile_cont].
The main difference is that instead of using a {{WITHIN GROUP}} clause, the
array is passed in directly as the first argument to the function.
