It turns out Pinot's `EXTRACT` function is case insensitive. So we don't need to make any changes for this function. - The `ExtractTransformFunction` is [case sensitive](https://github.com/apache/pinot/blob/60ee5eb0e8a2cf8276565ae8b20fb81292315843/pinot-core/src/main/java/org/apache/pinot/core/operator/transform/function/ExtractTransformFunction.java#L52). - The [SQL Parser](https://github.com/apache/pinot/blob/6eeb9fb5946c3e08eb3f48c72205092517539e60/pinot-common/src/main/java/org/apache/pinot/sql/parsers/CalciteSqlParser.java#L130) converts the `field` to upper case. - For example, if the query is `select EXTRACT(month FROM '2017-06-15') from airlineStats`, the `SqlNodeList` is parsed as ``SELECT EXTRACT(MONTH FROM '2017-06-15') FROM `airlineStats` ``. -- This is an automated message from the Apache Git Service.
