> Hi, I wrote some codes for query parser. These diffs are aimed to pass test
> case of query parser, especially org.apache.drill.parsers.DrqlParserTest.
> To do that, I modified the DrqlAntlr.g and AntlrParser.java.
> - Add some rules (N_AGGREGATE_FUNCTION, aggregateFunc, ... )
> - Swap groupbyClause rule and havingCaluse rule in selectStatement
> - Modify some parsing routine in AntlrParser.java
> I think that the defined grammar still has some problems even if this diff
> is applied. Also, it is not important thing. However, you can pass test
> case ;)
