Class SqlRichDescribeModel

java.lang.Object
org.apache.calcite.sql.SqlNode
org.apache.calcite.sql.SqlCall
org.apache.flink.sql.parser.dql.SqlRichDescribeModel
All Implemented Interfaces:
Cloneable
public class SqlRichDescribeModel extends org.apache.calcite.sql.SqlCall
DESCRIBE MODEL [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 SqlDescribeModel.
