Class SqlRichDescribeFunction

java.lang.Object
org.apache.calcite.sql.SqlNode
org.apache.calcite.sql.SqlCall
org.apache.flink.sql.parser.dql.SqlRichDescribeFunction
All Implemented Interfaces:
Cloneable
public class SqlRichDescribeFunction extends org.apache.calcite.sql.SqlCall
DESCRIBE FUNCTION [EXTENDED] [[catalogName.] dataBasesName].sqlIdentifier sql call. Here we add Rich in className to follow the convention of SqlDescribeTable, which only had it to distinguish from calcite's original SqlDescribeTable, even though calcite does not have SqlDescribeFunction.
